Mpeg-2 bitrates and specs for broadcast

Need some advice please for a new "ad server" system I wil be using soon..
1.Spec preference is for 25Mbps .
Is that achieved via Target Bit rate or Maximum Bit rate in the AME export settings?
2. Spec preference is 50i Upper field dominant.
AME does not have that option.
Is 25 Progressive effectively the same?
3. Spec preference is 4:2:2 (MPEG-2)
No option in AME for that... so what does one do?
4. Any advice on other MPEG 2 settings GOP N /M frames etc...for best results?
BTW- will be doing a workflow and pipeline test with faciilty. Just wanted a starting point.

Check this Apple Compressor help section - it contains quite good explanation of GOP.
In regard to best settings for M and N I don't have an unequivocal answer...
P- and B-frames require to store less data than I-frame. Hence, the longer the GOP, the higher the compression (the lesser the file size). That also implies that with the same overall bit rate you can get I-frame of a better quality, 'cos larger fraction of data will be allocated to each I-frame.
On the other hand, longer GOP is more sensitive to data damage, error propagation etc. Not to mention that P- and B-frames are of a slightly worse quality, which results in subtle flickering - have a look at e.g. this AVC-Intra vs H.264 blind test:
According to religious beliefs (see Apple help section above), GOP sequence duration equal to 1/2 second provides balanced compression/stability ratio. Hence Jim's suggestion about N=12. Also repeating P- every other frame with M=2 improves both resistance to data damage and picture quality. Therefore, choosing between Jim's and Joe's suggestion I'd be more inclined to M=2 and N=12 (sorry Joe... )
However, I can be completely wrong. So, happy confusion! (© Joe Bloe Premiere)

HDV mixed format editing and mastering for broadcast TV

Hi
I have HDV blues with regards mixed format and multi time base.
Any help advice will be greatly appreciated.
I have never handled HDV in multiformat and multiple timebase to Mater and output for Broadcast television.
I am hoping to master to DVD directly on the configuration ( details provided below ) to deliver to NTSC and PAL market for DVD retail.
However I would need to take to a post house, one or more quicktime file to Output to Digital Betacam for television broadcast for both NTSC and PAL formats.
with regards
problems I am facing are on two fronts:
1) I am unsure of best quality and workflow to output master on Digital Betacam tape for broadcast TV in NTSC and PAL both formats.
2) With sequence set at HDV 1080 50i, and export setting as current setting, upon render and export of self contained quicktime direct from FCP timeline I face few troubling symptoms;
- that the quicktime exports 3mins to 35 minutes of qt clip but not the whole program of 90 minutes as one clip. System crashes and I have to reboot.
- Another symptom is that by doing above my time line shows aduio as out of sync to video. here i see that Audio tracks A1,A2 as being torn apart at cut edit points and have gap of 1 frame at random ( but not on all edit points ).
A3, A4 and other music and sound fx tracks have slipped off sync by few frames , again at random and also other places the edit comes back in sync with audio.
- Of course I am having to re- render this sequence timeline a zillion times even though the previously rendered files still exist in relevant folder.
Program duration: 90 minutes
current sequence : 1440 x 1080 at 50i
edit sequence time-line consists following source material directly ingested from tape via firewire in native HDV and DV:
VIDEO
-HDV footage of 1440 x 1080, 50i
-HDV footage of 1440 x 1080, 60i
-PAL footage standard and widescreen
-NTSC footage standard and widescreen
- still images

Hi guys, thanks for getting back to me. My client has now changed her mind and so I'm just mixing XDCAM and HDV 16:9 footage which is absolutely fine. Awesome. Thanks for your help!
I have one issue - some of the XDCAM footage she has given me is .MP4 video (actually each clip is a folder with 5 files in it (.MP4, .SMI, .PPN, .XML, .BIM). Do I have to convert the .MP4 into .MOV via Compressor to work with it (presumably this will compress it somewhat) or can I convert it simply and losslessly somehow (perhaps using sony XDCAM software?)
Thanks again for any help!

Does anyone know what is the exact HDD model and specs for MacBook Pro (15-inch, Mid 2012)? Thanks

Does anyone know what is the exact HDD model and specs for MacBook Pro (15-inch, Mid 2012)? Thanks.

Thanks for responding me,
I just got this info from the link that you provided me but is there any model name or model number for it?
or any 2.5 would be work?
Thanks again.

Maximum bitrate and size for Apple TV3

Hello,
how much is maximum bitrate and file size for Apple TV3 homesharing? I transfared some bluray, but it lags. Im streaming via cabble.

No official answer on this but specs say:
Video Formats
H.264 video up to 1080p, 30 frames per second, High or Main Profile level 4.0 or lower, Baseline profile level 3.0 or lower with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
MPEG-4 video up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format
AppleTV 2/3 have less than 8GB of memory to buffer movies but there are movies over 8GB and I've certainly streamed larger than that.
What lags? Playback? Stuttery display?

BEST Workflow? MPEG-2 Cutting and preparing for DVD...

Hi all
I am in the process of putting together a showreel. The only way I can get my work on a DVD is to record the DVB-T Stream (its Swiss Television), which Quicktime says is "MPEG2 Muxed, 720 x 540 Pixel" - and it's with 25fps.
Now I'd love to cut those Files in FCP with as high quality as possible and export it for DVD-Studio. If I would not be cutting these files, as I already did last year, there is not much conversion but only demuxing needed to use them in DVD Studio.
But how can I cut those MPEG-2 in FC Studio 2 without much quality degredation?
Whats the best workflow for this?
I read somewhere here in that forum, that I have to convert this into DV, cut it in FCP, and then convert it again to MPEG-2 -- but that sounds like a lot of compression going on...

Thanks for your reply Shawn.
Im aware of the fact that a recompress is not the best way to go. But I don't have any other chance, since a broadcasted signal is already in MPEG-2 and there is nothing I can do about it, this is my only available source. There is no tape for me.
I was basically just wondering if there is something like a smart Compress..say, it only recompresses where there have been changes, between two I-Frames... and evrything els thats unchanged just get copied. that would be the way to go...

Best size and specs for Wallpaper photos?

If I want to import some of my jpegs for iPhone wallpaper, what's the optimal size (and other specs, like resolution)?

I wouldn't recommend having lots of huge picture files on ur iPhone...make a folder of smaller versions of the pictures. I think 480-by-320 looks great already...if you want you can add up a little more than that if your going to plan on zooming in to an object/person on the photo (if there's more than one person on the pic) and just crop that one person for your wallpaper then go for a little more than 480x320...

I don't have a Mac Pro 1,1.
But in my Mac Pro 3,1 I installed an ATI 5770 and it works great. Drop it in, reboot, done.
Althogh, when you go to purchase it from Apple's on-line store, the compatibitlity show a Mac Pro mid 2010. I'm not sure why, that troubles all the rest of the Mac Pro users.
I'm assuming the 5870 would work as well. That provides more GPU memory, but I'm not sure what impact that has on FCP X.

Is there any mechanism for broadcast messages for every client?

Hi, all
I just wanna to develop such a kind of chatting program. So I just build the communication structure for that. I want to use UDP protocol to send and recieve messages. As we know about that protocol, it does not need connection between server and client, so some packages will be lost. I just used only one DatagramSocket to recieve and send any messages back and forth. And I implemented the client using multithread technique. The problem is that when multiple client sent messages to server, how could server broadcast the specific message to all clients. I am very headache about that. I just used Vector to store diffrent address and port. And when a meesage arrived, I will firstly make ajustment about whether the address and port had been stored, if not, I will add, otherwise I will ignore it. So I think it will be terrible that if thousands of clients connected to the server, how big Vector will be. So I want to know whether the Net package or DatagramSocket provided some kind of mechanism about broadcast messages for every interested client. Thanks. Here is my code below:

Hello Amir,
ACS used to tie the license to the MAC address of the machine but I believe Cisco removed that in version 5.1 or 5.2 as users were facing with issues if the MAC changed on a virtual machine.
Other Cisco products, such as the ASA, Call Manger, and even ISE are a lot more restrictive when it comes to licensing. However, Cisco in general has many products that are licensed on the "honor system" where you are responsible for reporting and paying for everything that you are using.
Also, I suppose Cisco could audit any companies out there and figure out what the company is using vs what it actually paid for :)
I hope this helps!
Thank you for rating helpful posts!

Re: specs for project settings and final delivery of animations for HD broadcast

Hi all,
i just finished reading the studio techniques book by mark christiansen and i have i few doubts, maybe someone working on similar proyects can help me out, i hope so!!
i live in a PAL country and i mostly design and animate infographics in AE with shape layers, illustrator files and psd files. i may work in a proyect for HD tv broadcast and some issues and insecurities had crawled in. i would like to describe wich will be my guess as to the workflow:
1- setting up the project in AE:
obviously the color working space should be consistent between aplications. Linearize is important but i don´t fully grasp the concept.
2) my master composition:
here, the choice of frame rate should be 25/50 depending on..? is just a choice if you work with live footage from hd cameras? applies to animations,graphics?
And last question, which would be the preferred delivery file format and encoding? i know the choices are wide but if you have a setting that´s working for you and your clients then i´ll be helpful.
Also. if you have an article you can recommend where there is a clear explanation it´d be appreciatted, it seems (for me) the deeper you digg the more confused i become.
Thanks in advance!!

You must check with the broadcaster. They either publicly publish their requirements or they are listed in a contract. There's no one size fits all here. The best option for broadcast work is to render a lossless or nearly lossless copy of your work as a DI (digital intermediate) and then compress the project to the exact broadcaster specifications using Adobe Media Encoder or another app specifically designed for compressing video for delivery. The only time you ever look like an amateur is when you don't ask for the specifications. I regularly deliver the same footage do different distributors in 6 different formats.

Preparing Music Video for Broadcast in Premiere and Encore?

I am trying to prepare a music video for broadcast in Premiere Pro. However, the specs require audio (Ch. 1-2 stereo, Ch. 3 mono Ch. 4 mono). I can't find a way to do this in Premiere Pro. I seem to be able to do this in Encore - I can create four audio tracks.
Problems so far:
1. I can only import the stereo wav file onto track 1, and have to import it again on track 2. The stereo mix isn't spread across both tracks Left/Right. Will the stereo mix appear on the correct tracks when delivered for broadcast?
2. I need to export the video as an mpeg 2 on my hard drive - not actually burn to disc. Can I export an mpeg 2 video file without burning to disc?

I am delivering the master as an mpeg 2, uploaded by FTP.
Here are the audio specs:
Stereo Left and Right audio signals must appear on channel 1 and 2 respectively
Dolby ProLogic matrixed audio (Lt /Rt) may be substituted for Stereo audio on channel 1 and 2 if desired
Monaural audio may be substituted for Stereo on channels 1 and 2, but must appear on both channels and must be in-phase.
Secondary Audio Program (SAP) if available, must appear on Channel 3, otherwise a mono mix of Channels 1 and 2 should appear on Channel 3.
Descriptive Video Service (DVS) audio, if available, must appear on Channel 3 if delivered in lieu of SAP audio
DVS must appear on Channel 4 if delivered in addition to SAP audio, otherwise a mono mix of channels 1 and 2 should appear on channel 4.
So basically, I need a Left and Right stereo on Ch. 1 and 2. And mono on 3 and 4, because I don't have SAP or DVS content.
I can create 4 audio tracks in Encore, then I import my stereo wav file and mono wav file. But when I drag the stereo wav file onto audio track 1, both channels of the stereo wav file are on track 1. I read in Encore's help files that (assuming this would be going to DVD and not an mpeg on my hard drive) only one audio track can play at a time. Each individual audio track appears to be stereo, but I don't know how they would each correspond with the requirement for Ch. 1 to be stereo left and Ch. 2 to be stereo right. As of right now, it appears that track 1 is both left and right, and I can import the same stereo wav file on track 2 seperately with both left and right audio.
The specs I'm trying to meet are Viacom/MTV which is a major outlet for music video content, so I'm assuming their requirements are reasonable enough.
As for making an MPEG2 from Encore without burning a disc, here is the format:
Container: MXF OP1a (SMPTE 378M)
Resolution: 1920x1080i (interlaced) 16x9 aspect ratio
Encoding: MPEG2, High Profile@ High Level 4:2:2, 50Mbps Long GOP, CBR, 29.97 frames per second (59.94 fields per second)
Audio: Uncompressed 2-, 4-, 12- or 16-channel audio, 24bit @48khz, BWF (SMPTE 382M). All audio channels must be contained within 1 MXF track.
Not sure how to export from Encore - only options I am seeing involve burning to DVD or Blu-Ray.
I really appreciate your help thus far!

SPECS FOR NEW MBP HARD DRIVE AND HOW TO INSTALL NEW OS AND USE TIME MACHINE

I need to replace the hard drive in my early-2006 1.83 MacBook Pro (15-inch), because the Genius at the Apple Store told me that I'm getting weird behavior on it due to the drive slowing down and that it won't last much longer.
I have 2 questions:
First, I want to order the drive online and have it installed locally. I will probably get a 320 to 500GB drive. What are the exact other specs I will need to find the right one?
Second, I am currently running 10.5.8 and backing up with Time Machine. I would like to install 10. 6 on the new drive, but don't know how to go about using the Time Machine backup to get all my apps and files running. Can someone describe this procedure for me?
Many thanks!

Hi Annie,
You need a 2.5" 9.5mm high SATA HD, either 5400 or 7200RPM. Check out macsales, newegg, amazon to name a few places.
How to restore from a TM backup: http://support.apple.com/kb/ht1427
Prepare your HD by formatting and partitioning it:
1. Boot from install disc (press power button, immediately insert install disc and hold down c key).
2. Select your language.
3. Open Disk Utility from Utilities menu.
4. Select the HD in the left pane (the manufacturer’s name and the HD model number).
5. Click on the Erase tab.
6. Choose the Format: Mac OS Extended (Journaled).
NOTE: if you want to zero the HD (which I always think is a good idea, but does take time), click on Security Options, click the button for Zero Out Data, click OK. The larger the HD, the longer this will take, in some cases several hours.
7. Click on Erase and wait for the entire process to finish.
8. Click the Partition tab.
9. Click on Volume Scheme: and choose the number of partitions (normally just one unless you have other plans).
10. Click on the Options button (located underneath the Volume Scheme pane) and select GUID.
11. Click Apply.
12. Quit Disk Utility and continue with the installation process to install OSX or run Restore from a TM backup; when finished, repair permissions, run updates, repair permissions.

What follows is a grouping of some of the most fruitful procedures - from what I've seen in the biggest battery life issue thread - and some background information and discussion for solving or improving the battery life with the iPhone 4S and may be applicable also to devices on which iOS 5.0/5.0.1 has been applied. Credit goes to the respective users who contributed this information to the forum and they should be commended for doing so. This is not a final listing. The goal here is to provide a first stop sort of knowledge base document for newcomers instead of having them perusing the never ending threads where the wheel is reinvented on every page...
Please don't post your questions, usage screenshots, or claims that it worked or not for you or anything here except PROCEDURES/DEBUG STEPS/SOLUTIONS or improvements to the procedures already listed here. Try to use point form and to be as concise and clear as possible. Hope all this helps.
Thank you and good luck!
General info and specs
First, take a look Apple's battery tips, info and specs(obligatory reading for all Iphone 4S users - read it once and for all):
http://www.apple.com/batteries/iphone.html
http://www.apple.com/batteries/
... you didn't read it? loll Always remember this i.e. the definition of "usage":
Usage: Amount of time iPhone has been awake and in use since the last full charge. The phone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.
I'm still not convinced you read the links so here's what Apple has to say in terms of fine tuning your battery life:
Optimize your settings
Depending on how they are configured, a few features may decrease your iPhone battery life. For example, the frequency with which you retrieve email and the number of email accounts you auto-check can both affect battery life. The tips below apply to an iPhone running iOS 5.0 or later and may help extend your battery life.
Minimize use of location services: Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > General > Location Services or use location services only when needed.
Turn off push notifications: Some applications from the App Store use the Apple Push Notification service to alert you of new data. Applications that extensively rely on push notifications (such as instant messaging applications) may impact battery life. To disable push notifications, go to Settings > Notifications and set Notifications to Off. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.
Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.
Turn off push mail: If you have a push mail account such as Yahoo! or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.
Auto-check fewer email accounts: You can save power by checking fewer email accounts. This can be accomplished by turning off an email account or by deleting it. To turn off an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off. To remove an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and tap Delete Account.
Turn off Wi-Fi: If you rarely use Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to Off. Note that if you frequently use your iPhone to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.
Turn off Bluetooth: If you rarely use a Bluetooth headset or car kit, you can turn off Bluetooth to save power. Go to Settings > General > Bluetooth and set Bluetooth to Off.
Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
Adjust brightness: Dimming the screen is another way to extend battery life. Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions. Go to Settings > Brightness and set Auto-Brightness to On.
Turn off EQ: Applying an equalizer setting to song playback on your iPhone can decrease battery life. To turn EQ off, go to Settings > iPod > EQ and tap Off. Note that if you’ve added EQ to songs directly in iTunes, you’ll need to set EQ on iPhone to Flat in order to have the same effect as Off because iPhone keeps your iTunes settings intact. Go to Settings > iPod > EQ and tap Flat.
Usage specs for the 4S - http://www.apple.com/iphone/specs.html:
Talk time: Up to 8 hours (12.5% per hour drain) on 3G, up to 14 hours (7.1% per hour drain) on 2G (GSM)
Standby time: Up to 200 hours (0.5% per hour drain)
Internet use: Up to 6 hours on 3G (16.6% per hour drain), up to 9 hours (11.1% per hour drain) on Wi-Fi
Video playback: Up to 10 hours (10% per hour drain)
Audio playback: Up to 40 hours (2.5% per hour drain)
So a scenario of normal usage could be for example: 4 heavy hours of 3G internet browsing (66.4%), with one hour of call on 3G (12.5%) and 22 hours of standby (11%) = 100%
A battery life issue is a problem where the drain is really out of spec either during usage or standby or both. For example, multi-% per minute drain during usage or a 10% drain per hour during standby is problematic. Browsing the internet on 3G during one hour and losing 16-17% is not.
Apple's test methodology for claiming the specs:

Procedures
davidch tips (reset+full discharge recharge):
Go through these steps to address the battery after updating to iOS 5.0.1:
1. Reset all settings (settings app-> general-> reset)
2. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there). Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)
3. Turn off system location services timezone and iAd
4. Fully discharge battery (tilll it shuts off with the spinning wheel)
5. Fully recharge battery (overnight if possible)
In my experience this improves the Standby battery drain issue significantly in most cases. It reduces drain from 2-4% or more per hr to 0.5% or less. It has worked for many, many users now. If it does not work after a few try's you may have a real battery or hardware issue and should contact Apple. Good Luck!
ram130's variant of davidch i.e. additional steps:
Now using davidch original steps and attaching the tweaks I made to get me more usage. As shown on page 29.

4. Fully discharge battery (till it shuts off with the spinning wheel)
5. Fully recharge battery (overnight if possible)
6. Disable Siri 'Raise To Speak' and REBOOT *( if possible use another camera to verify the                 infrared is off after the reboot).
7. Set emails, icloud and calendars to fetch. ** test. Mines on hourly.
8. If your in a no signal and your phone is saying "Searching..." even after 10mins, reboot while in that area and after 1-2min it should say "No Service". This mainly applies to Verizon customers and improve battery life in these areas.
9. *optional* Goto Settings > General > Network and you will see "Hotspot.." loading something, wait a few seconds and it should say "setup personal hotspot" then exit out.
* I notice a great improvement after disabling this and rebooting. This increased my "screen on" usage or at least helped it. Make the change.
** I have not tested push yet to narrow down the drain but I had this change on my phone. I believe exchange push is responsible for some stand by drain. As for icloud, haven't notice much of a difference. Just try it for a day. My email still came in fast most times. Again still testing, will report back on these..
buxbuster tips(wifi sync, iCloud):
These are my own tested workarounds that worked for my iPhone 4S and seemed to have worked for others as well :
Workaround number 1. Deselect wifi-sync in iTunes and press sync.
If that doesn't work try :
Workaround number 2 : Remove iCloud, reset network settings. ( I guess this won't work for you since you don't have it enabled ).
If both workarounds fail, you can always try to completely wipe your phone. That also solved some of the cases out there.
rolandomerida tips - i.e. buxbuster and additional steps:
Finally, I solved the syncing error loop. My contacts are syncing flawessly again between my devices and iCloud, and yes, the battery stopped draining, which is the main topic here.
I followed instructions from buxbuster (check his workaround a few pages up!) and an additional BIG step to restore contacts and syncing, as seen in a MacRumors forum.
This is what I did:
1. Make a backup of your Address Book, using the vCard option (or both, it doesn't hurt). Save it for later.
2. In your iPhone, delete iCloud account. When it asks, accept both: delete AND delete from my iPhone.
3. Reset network settings. The iPhone will restart, then will ask you to unlock the SIM card.
4.Turn Wi-Fi on.
5. Add the iCloud account again.
That's for Buxbuster's workaround. For some, it might work just like that. My iPhone repopulated from iCloud after step 5, but I still had that "server error" on iCloud. I had to do some extra steps, since my Mac was not syncing to iCloud and couldn't edit anything on my Mac or iCloud. Syncing back had to be fixed, too. If not, the syncing loop would continue from my iPhone, and the battery would drain awfully again.
1. In System Preferences -> iCloud, I turned Contacts off. I chose "keep on My Mac" those contacts, but I got an empty Address Book after a while. And a few minutes later, iCloud contacts were empty and my iPhone also. It is scary at first! Now, before importing that vCard backup...
2. Turn Wi-Fi off. This is important, since your contact-empty iCloud will attempt to wipe your Address Book from your Mac in seconds after importing.
3. Import your vCard backup to Address Book. Just drag it to your blank Address Book window; it asks if you want to import "x" number of cards. Of course, say yes.
4. Turn Wi-Fi on, and then iCloud contacts on again (System Preferences -> iCloud). It will offer to merge your newly populated Address Book with iCloud (which is empty at this point). It should upload every single contact to iCloud, and then to your iDevices. If not, a fifth step would be to import the vCard file to iCloud, but it shouldn't be necessary.
So, with iCloud syncing working correctly, there is no battery draining! Again, that was my particular issue.
I can't tell if this is the single answer to the widely spread battery draining problem, but it sure can be fixed with these workarounds, and yes, Apple should address the problem with a future update, for we affected customers don't need workarounds in the first place

Miless tips (full 800mb release of 5.0.1 and sanitizing a restore):
As for 4S battery life. Try doing this,
1. Settings>Location Service ... disable all location services you do not need. In particularly Facebook because it drains the battery a lot.
Scroll down to the bottom at Settings>Location services>System Services ... Disable Setting Time zone, location based iAds, Diagnostic & Usage.
2. Settings>Notification>Calendar ... turn off the Notification Centre.
3. Settings>General>Reset ... do Reset All Settings. Doing this will not wipe out your iPhone. It will just Reset the network settings, location warning, keyboard dictionary, etc... but it will clear up some corrupted data there. Generally this will help.
Try these 3 steps first... if it still drains a lot, try the following,
4. Drain your battery down to 1%. Then charge it up using USB from PC ... not the charger. The charger output 1.0 A ( x 5V from USB ... you get 5W power). From PC, output is only 0.5A x 5V = 2.5W power. Charging is slower but trickle charge 4S helps the battery retain its charge better. I think it takes about 3-3.5 hours to charge full from USB/PC compared to slightly below 2 hours using iPhone charger.
If after doing the above still could not solve your battery issues (mine with iOS 5.0 was ok up to step 4, but not iOS 5.0.1).... plug you iPhone to a charger (any charger), from iPhone, access your iCloud ... set it up if you havent. Back up your iPhone data to iCloud. if you do not have enough storage (only 5GB is free), go to details and select the apps you need its data backup, choose only those you really need and leave those unnecessary ones out. Back up your camera roll to your PC/Mac manually as it could be too big to backup to iCloud.... once you have it setup, make sure you are on Wifi ... tap backup to iCloud from your iPhone. It will take a while if the file is huge.
Once backup to iCloud is completed, plug your iPhone to PC/Mac and launch iTunes 10.5.1 (make sure you have 10.5.1)
Click Restore. It will automatically initiate a download of iOS 5.0.1 ipsw for iPhone 4S. Wait for the whole process to finish, ie. download, restore software/firmware.
Once its done, do not set up your iPhone from iTunes. Set it up on your iPhone. Go through the selection. When prompted, select restore from iCloud (from your iphone backup earlier). Keep your iphone plugged into iTunes while restoring backup from iCloud. Because while restoring from iClouds, some data will be synced from iTunes if you plug in, e.g. music, video, etc... unless you bought these content from iTunes store. Apps will be downloaded from App Store from the cloud.
Once it's all done restored. Turn off your iPhone,.. and turn it on again.
Now, hopefully your battery wont be draining so fast anymore. Usually it wont after this. But you need to charge your battery at least 4-5 cycles to stabilize the charge on the battery. I dont know why... but battery life seems to get better and better for me after a few charge cycles after all the above work.
Good luck. Let us know if it works for you.
W. Raider tips (Sirii):
Bottom line for me of things that helped battery life are:
1. Turing off Siri and Rebooting the phone by holding the Home button and Top button down, ignoring the slider, until the phone shut down. (turn off Siri, reboot, and check top front of iPhone 4S against a lesser camera like the front-facing camera on an iPad2 - making sure the IR sensor is off)
2. Fully draining the battery, meaning using the phone until it shuts itself off from a drained battery and then recharging it to 100% about 4, maybe 5 times. I charged it both with a Mac and a wall charger.
Hope this is helpful!
Comments
jmm514 remarks (Twitter):
I may have found something. I had Twitter disabled in my notifications, but got a tweet today that popped up on my home screen. Didn't know I had this enabled. At the bottom of the Twitter notification settings is the home scrren toggle. Since disabling this, battery life seems better. Considering there is no setting for frequency of checking for tweets, it appears the phone is continually connecting to wifi to check for new tweets.
tmksnyder comments (notifications, corrupt data in iCloud):
For me, I found my iphone on wifi mysteriously connecting to my mac. I eventually narrowed it down to the Apple Move Trailers app which keeps a file in iCloud. The phone was trying to sync the file with the mac in the background even when the Movie Trailers app was closed (hitting the red x). Based on my macosx logs the iCloud process that was trying to sync was working directly between the phone and the mac without using itunes by connecting to an https address hosted on the phone. It was connecting every 3 minutes and failing (while phone was awake or awake during during a notification). I also found that iCloud control panel on OSX would error if I tried to delete the file. I fixed it by removing the App and doing a hard reset which stopped the sync. I probably could have turned off iCloud document sync in the phone but didn't think of that. My battery life has greatly improved while at home on wifi.    I am now at 28 hrs standby, 2 hrs 20 minutes of usage, and 68% battery. It was ok before where I could get 20-30 hrs standby and 6 -8 hrs usage. My usage today was phone calls, 3g surfing, and music via bluetooth in the car.
I also found even with Itunes iMatch, if I mass updated tages, art work etc, it would hit the phone on wifi even in standby. I was amazed.   Granted if I am not doing updates, Match won't hot the phone so this was a once in awhile event. I could drop my percentage by 5-10% in a matter of minutes when doing updates.   I think a lot of our problems are background processes, associated with iCloud, notification, and apps. More features means more battery.   I think the key thing is to keep track of what has recently been added or changed if battery life gets worse all of a sudden.   It may be an app that was recently installed and if possible you may want to completely remove it and not just quit it.
With twitter, i think it uses push notifications so it doesn't need to be running and actively poll on the phone. For instance , if i quit the mail app, i still will get mail notifications and can swipe the message and load mail. Apple Push Notifications servics maintain the connection to the phone and there are likely pings or connection checks that occur for the service on an os level not an app level. This minimizes the load so there arent a bunch of apps all runing and constantly checking. The notification service , if it is contacted from twitter or another service with data, will check the settings you have registered to the with the apple push service and send the notification to your phone. No matter what, there is a drain with notifications. M hunch is once one application is configured to receive notifications, connection checking occurs betwen the push service and the phone so it knows where it is on the network. If it is implemented correctly, these checks arent frequent if you are still and more frequent as you move. The other drain is for when the noification hits and is processsed. If i get 9 emails over night, my screen just popped up for 20 seconds or so to process each message using battery. I would even think that just go from low power to turning n the screen uses more juice than if the device was already on and i get the message. On nights I get no notifications, I see a 3 or 4 percent drop. On nights with a number of notifications, i have seen up to a 10 percent drop. Besides notifications, wifi sync and icloud will poll on the local network and use up battery if the host computer is on and running itunes or trying to sync a data file that is corrupt (which i had with the apple movie trailers app causing my phone to drain). For me turning off wifi sync and remving a corrupt file in icloud solved my battery issues and I get over 24 hrs of standby with 6 to 9 hrs of use and this is with all the normal location services and push serivices turned on.
See http://developer.apple.com/library/mac/ipad/#documentation/NetworkingInternet/Co nceptual/RemoteNotificationsPG/ApplePushService/ApplePushService.html for more info. I think it has a good overview of how the notifications work.

Well seems like that rumor of iOS 5.0.1 is finally gone the way of the dogs since developers got a beta of 5.1. So as stated earlier in the master discussion-> I suspect if you are filling up this thread with false post or creating a master set of links to various post that are unreliable you are wasting your time. Press is not going to touch the story due to poor or inaccurate sources which may be links from the master thread. This can include inaccurate information, combination of conflicting post or postings from users which may not own the device. Reputable press organizations have policies that require discloser and strict rules about what is a reliable source for a story. It is clear that many of the post in the master thread, which are links presented here are questionable.
Sorry to say that postings taken without any analysis of their totality have been propagated via various sites, for example sites such as http://www.2012federalbudget(dot)com. (Do not visit but I suspect that this is not the 2012 federal-budget site you would expect based on analysis of the records. There are plenty of sites like http://www.2012federalbudget(dot)com propagating questionable post in these threads.) One site for example in the discussion thread used a self signed certificate, the site had a log in to allow users to enter their OpenID. Seems many of these sites are pop and drop drupel configurations.
So remember this is how the really bad rumor of iOS 5.0.2 got started, the 5.1 memory leak issue, iCloud Issues, call quality, address book, etc.
Some of the postings have been very comical, I think the latest now is a dropbox issue. Seems that the length of the previous thread has resulted in various app engines of some proxy servers/tools reaching their limits.
So I would make sure to know the source of any information you link to. Make sure you avoid entering any information to outside links such as OpenID or Apple ID, these are big prize items for anyone with malicious intent. If you have issues and are a valid user contact APPLE CARE. (Note link is using McAfee Secure Short URL Service, and is https.)
http://mcaf.ee/ricdt
The original solution still represents a high level of success for users having any battery issues.
Install 5.0.1 on your iPhone 4s. Some users posting they are still using older versions, bad fake serial numbers, etc.
Make sure your device can run iOS 5.0.1 and is not altered.
Make sure you use a new Sim, not some cut down version which many users admit to doing. (Again, worth confirming what people are posting.)
Reset the device doing a hard reset and software reset.
Let battery drain and then charge for the full cycle, which is 24 hours.
I think you will find you will get the battery usage that APPLE has stated for the device.
Best of luck, stay safe and thanks

Computer specs for nice 3D rendering/ after effects rendering and video rendering in general ?

Hi there! I would like to know what the perfect specs for a laptop/workstation/computer are, so that I could do my creative work from home..my old laptop (Macbook Pro, 8Gb Ram, V 2010) is not good enough for 3D rendering, not even Video rendering or After Effects... I need to know what graphics card for eg or how much Ram or what I need to look for in a computer so that I won't get any error messages after rendering for half a day anymore...;) (--> very annoying) Money is not a first priority...i would first like to know, what the best option would be that one could have and then down size from there;)
I would appreciate every help:) my laptop is dying...i need something new and better;)
cheers stephs

Regardless of workflow, you want a workstation, not a laptop. You will get much more bang for your buck.
Also, as others have said, Windows machines tend to be better choices than Macs right now. And that's coming from two people who used to use/love Macs...
In general, you want the fastest clock speed on your processor that you can afford. You want as many cores as you can get with that nice, high clock speed.
Ideally, you want 4GB of RAM per core of your processor - MINIMUM 16 GB of RAM, (but get as much as you can afford).
You want an SSD for your cache and a good-sized regular hard drive to hold footage, renders, etc.
GPU matters for Premiere and any third-party plugins that use it (like Red Giant Universe, Element 3d, Mettle's ShapeShifter, etc.), but not for AE and not for Cinema 4D (which comes free with AE these days).
Again, this is just some generalization. For more specific info, we'll need to know more about what you're doing.
Also, you don't need to take our word for any of this; read what Adobe has to say on the matter: FAQ: What computer and components should I buy?

Server Specs for SLES and GW 12

I need to look into a new server to put SLES and GroupWise 2012 on it. I am having trouble finding server specs for this, so I was hoping to get a little advice. GW will be the only thing on this box, one PO with about 150 users. Hoping to build something or purchase something that isn't too expensive due to budget restraints.
Thanks

I work for a small non profit organization and we only have one server, never found the need for virtualized servers.

If this is going to be a dedicated physical setup (you are not planning
to run GroupWise on a virtualised server) you should not need a big
budget to find a decent server for those 150 users.
IMO, a dual core CPU with 4 GB of RAM would seem quite sufficient in
this case. Getting a proper disk controller (with a true hardware raid
handling if you are looking for a raid setup) & decent disks that can
handle the I/O required is important too.
The A brand entry level servers that I've seen easily meat this
requirement. Do make sure it's suitable for 64bit.
In any case, GroupWise 2012 has about the same requirements version 8
would demand.
I'm curious, you are not already virtualising servers?
Cheers,
