Why is QuickTime export only using 2-4 cores?

I'm trancoding video in QuickTime Player 7 (to H.264 and AAC), NTSC dimensions and good quality. It's taking quite a while, but it should be going faster for what I have. I have an 8-core Mac Pro, but the export process only ever goes a little above 300% CPU usage, meaning that it's using 4 cores max. My CPU isn't maxed out by anything else, and I have 3GB of free RAM.
Transcoding video is supposed to be a totally parallel task, but it's not using all of my cores. Any explanation or fix for this?

Premiere Pro and Adobe Media Encoder will take all the resources it needs to do it's work. If it's not using all available resources, it's because it just doesn't need them. One possible reason for this is you're using an effect that's just very slow.

Pages '09 only uses one processor core?

Hello,
some days ago i had to open a document containing nearly 2.000 pages. Don't ask why.
Working with this document was quite complicated because Pages was responding very slowly. I used the activity monitor to see what was going on and i recognized that Pages only uses one core of my eight core MacPro.
I tested iWork on my iMac and MacBook Pro (both DualCores) as well: same problem.
Does iWork only use one processor core?
Kind regards,
roman

How much memory do you have in your system? I'll bet if you check activity monitor (applications/utilities) and go to system memory tab therein you will see lots of page outs. This happens with huge docs and little memory as the doc is being swapped between active operating memory and the hard disk The only way to solve this problem is to get more memory (not storage) in your system. For a 2,000 page doc you're going to need lots and lots and lots of extra gigs of memory. By the way - how big is the too big file of yours?
Number of processor cores isn't going to solve the issue if you have pageouts. It is a system memory/size of document issue and completely unrelated to how many processor cores you are using.

Why is quicktime slower when using multiple mdat atoms

Hi,
I've been trying to generate a mov file and I noticed that the more mdat atoms I put in my mov file the more the file takes time to load on QuickTime, iTunes.
Even worst, on the iPhone the file takes more than 3 minutes to load.
If there are too many mdat atoms quicktime even says that the file is invalid ( error -2004 or -2002, I don't remember exactly).
Why is quicktime/iTunes slower when using multiple mdat atoms ?
Thanks,

Yeah! Problem solved: It's a QT issue.
Cause: Mac Update Software downloaded a faulty QT.
Solution: Download QT from Apple's QT site.
Great to have the Video back

Why does my printer only use 25% of the page and shrink to fit?

when i print certain things it only uses 25% of the page. It is so small i can't read it. If i go to print preview and modify the size, it puts it on multiple pages. I can't figure out how to change any settings.

Firefox extracts the paper size information from your Windows printer settings, so that's the first thing to check. In the print dialog, if you click the Properties button and review the dialog for your printer, do you have a small paper size selected and can you update it?
If Windows is correct and Firefox is mistaken, you can reset the stored paper size using the about:config preferences editor.
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the search box that appears above the list, type or paste '''paper''' and pause while the list is filtered
(3) Look for your printer's paper-related settings and then right-click and choose Reset for each (e.g., size, height, width, etc.).
If you return to your document and try Print Preview, does Firefox compute the correct size?

AME is only using one processing core out of six.

I have not been able to figure out why AME is only using one of the six processing cores that I have in my Core i7 hex core processor. I'm running Windows 7 Ultimate 64 bit and the latest version of AME 2014 CC. When I render in Premiere Pro CC 2014 all cores are utilized. The codec that I'm using in AME is "YouTube SD 480P 29.97 - H.264". The video that is being encoded is fairly complex but it is only 30 minutes long and AME is estimating 18 hours to completion. That seems pretty excessive for that length of video.
Any help would be greatly appreciated.

Re: AME CC2014 Very Slow Encoding

Multisim 11 only uses one CPU core during simulation

Hi,
Just recently I've been using MultiSim again, v11 if that matters, and simulating goes slow, to my opinion that is.
Now there are two things that I've noticed:
- Multisim only uses one of two CPU cores during simulation, not both;
- I've enabled CPU throttle (AMD's Cool'n'Quiet) but corespeed remains very low even though Multisim needs CPU power while simulating.
The simulating of a NE555-based LED-flash circuit requires about 28 seconds to get to 100ms in the simulation. Now if I can get the CPU to throttle up, by for example having Prime95 stress one of the two cores, then the simulation only requires 12 seconds to get to 100ms.
So here are my two questions:
1. Is Multisim 11 capable of using more than one CPU core while simulating? If yes, how can I get it to use more than one?
2. Probably not the right forum to ask, but is there a way to force Windows 7 Ultimate x64 to throttle up the CPU when Multisim starts simulating? Since Multisim does not seem to stress the only core it uses enough to throttle it up. Using Prime95 on one core does trigger a throttle up.
With regards,
Bart Grefte
Relevant specs:
Windows 7 Ultimate x64
Multisim v11
AMD A4-3400
16GB RAM

Completely forgot this topic....
Is there a good reason why there is no multicore support? Multisim can certainly use it for simulating.
As for the CPU throttling, I found a batch that can increase/decrease the "minimum processor state"-setting and it works immediately, no reboot required.
@echo off
powercfg.exe -getactivescheme > "%userprofile%\appdata\~apo.tmp"
set /p v_currentscheme= <"%userprofile%\appdata\~apo.tmp"
set v_currentscheme=%v_currentscheme:~24,36%
del "%userprofile%\appdata\~apo.tmp"
powercfg -setacvalueindex %v_currentscheme% 54533251-82be-4824-96c1-47b60b740d00 893dee8e-2bef-41e0-89c6-b55d0929964c %1
powercfg -setdcvalueindex %v_currentscheme% 54533251-82be-4824-96c1-47b60b740d00 893dee8e-2bef-41e0-89c6-b55d0929964c %1
powercfg -s %v_currentscheme%
exit
Usage is simple:
Start -> run -> c:\pathtobatch.bat 100
for "minimum processor state"-setting at 100%
Start -> run -> c:\pathtobatch.bat 5
for "minimum processor state"-setting at 5%
Please note that "set v_currentscheme=%v_currentscheme:~24,36%" is not the same for every language. The original batch had "set v_currentscheme=%v_currentscheme:~19,36%" (most likely for the English version of Windows 7), but since my Windows install is in Dutch, I had to change it in order for it to work.
Running the batch with @echo off removed will show why.

Quicktime exports only part of my movie to WMV

I'm trying to export a QT to WMV using QT conversion, but it will only convert about 45 seconds of the movie. Any ideas?

I would bet that you're using Flip4Mac in trial mode for that conversion process. You'll have to buy the license from them for $49. to get the restriction removed...it's worth it, if you do this sort of thing a lot. Go to the F4M preferences and click on the upgrad tab.

Why do my firewalls only use the domain username and password for login and enable passwords, not a different enable password like my switches do? The RADIUS config looks the same...

/* Style Definitions */
table.MsoNormalTable
{mso-style-name:"Table Normal";
mso-tstyle-rowband-size:0;
mso-tstyle-colband-size:0;

Issue:
Cisco firewalls require only one level of password i.e. the domain username and password are used for both logging in as well as reaching global configuration mode.
Background:
We have multiple Cisco network devices set up which authenticate to our Windows domain controller using NPS (Windows 2008 R2). The switches we have set up all function exactly as we would hope as they require your domain username and password to login to the device. They then require a separate password when you use the enable command, this is stored in Active Directory:
Switches:
Username:domain-username
Password:domain-password
SWITCH>enable
Password:enable-password-in-Active-Directory
SWITCH#
Firewalls (as they currently are):
Username:domain-username
Password:domain-password
FIREWALL>enable
Password:domain-password
FIREWALL #
With the firewalls however, they require your domain username and password first, and then your domain password again when using the enable command. I want the firewalls to use the enable level password that the switches currently use instead of the domain password again. The current configuration look like the following:
Current switch configuration:
aaa new-model
aaa authentication login default group radius local
aaa authentication enable default group radius enable
aaa authorization exec default group radius local
aaa session-id common
radius-server host 192.168.0.1 auth-port 1645 acct-port 1646
radius-server source-ports 1645-1646
radius-server key 7 1234abcd
Current firewall configuration:
aaa-server DC01 protocol radius
aaa-server DC01 (outside) host 192.168.0.1
aaa authentication ssh console DC01 LOCAL
aaa authentication enable console DC01 LOCAL
key 1234abcd
Any help would be great, thanks!

Cisco ASA works that way by design. You could remove "aaa authentication enable" and then you could use the "enable password" command to set your enable password.
But if you do that, then ASA would change your username to "enable_15". That would break Authorization and Accounting if you're using them. Let me clarify with an example
Firewalls :
Username:domain-username
Password:domain-password
FIREWALL>show curpriv
Username : domain-username
Current privilege level : 1
Current Mode/s : P_UNPR
FIREWALL>enable
Password:enable-password-from-running-config
FIREWALL #show curpriv
Username : enable_15
Current privilege level : 15
Current Mode/s : P_PRIV
If you're using Authorization and Accounting it's recommended to stick with your current behavior.

Quicktime export still uses reference movie!

I am trying to export a file to deliver to a client. It plays in QT player 7 fine--so I go to Export... and choose my settings, then click OK. Then I burn the resulting file to a DVD.
When I try to play this file on another computer, I get an error saying an audio.aif cannot be found, and without it the movie cannot play properly. This is the same kind of warning you get when you save a reference movie and delete the original file. But I didn't do that...I exported and waited as it recopied every frame!
What's going on?

Same problems here and have spent days on every variable option. Thank you though for the tip of Snapz Pro. I'm downloading a trial now to see if that works but I'm concerned about the quality of the final file. I'm actually thinking of finding a way to export the Keynote into a video editing program and bring the AAC or .Mov files in separately and re-size them on top of the Keynote Quicktime to re-edit the timings. Anyone tried that yet?

Quicktime X only uses one core on a C2D

On my mac mini C2D activity monitor shows that quicktime X refuses to use more then one core which makes hd movies look very laggy and bad. What can I do to make it use both cores?

QuickTime itself limits to a single processor/core in most cases.
Worst is that quicktime is slow to render movies.
I hope Apple will rewrite quicktime so it supports Open CL and Grand Central Dispatch.
Kind Regards

Why is Quicktime Pro only for Quicktime 7??

I just bought an upgrade to Quicktime Pro, but it is for Quicktime 7. My Mac seems to be Quicktime 10 and the instalation istructions don't work.
Why did the Apple store sell me an upgrade that is 3 versions out of date?
How can I get Quicktime Pro for my version of Quicktime?

Hi there!
I am a Mac newbie - just switched from Windows about 4 weeks ago.
I am confused!
My MacBook Pro came with QuickTime Player 10. I have downloade QuickTime Player 7 from the link Niel provided. I install it. But Version 10 still shows in my applications! Even after I reboot my Mac.
I purchased the Pro upgrade and obviously cannot register it until I figure out how to get 7 to appear.
Help! How do I get my MacBook to recognize Version 7?
Thanks in advance for any help!

Quicktime export to dv format (preferably PAL)

Hmmm,
I just read Karsten's post and I think I already know the answer but ...
I really need to be able to export a slideshow from iPhoto to DV PAL format. For some reason I can't understand, iMovie produces really bad moire interference patterns with my mum's still photos in the Ken Burns effect, but iPhoto doesn't. I can work around this if I can just do the photo animation and transitions in iPhoto then export to iMovie to add captions, titles, music, voice overs and chapter markers.
The highest quality export I can find is 640x480 which is virtually useless to me. Karsten's post suggests that the frame rate is for NTSC and I need PAL.
I was certain this was possible in previous versions of iPhoto - am I correct.
Why does Apple keep taking away the things I want - firewire, replaced iMovie HD with iMovie 08 (yuck!), export options (what have I missed?)
Anyway, I'm hoping someone can point me at a workaround that isn't too complicated for my mum.
Steve

Neither iPhoto 4 or 5 has a PAL option under the Quicktime export, only size options. Which iMovie version are you having trouble with? If it's V7 try downloading and usingiMovie HD 6 which has been made available to iLife 08 users who want the many features of V6 that were dropped out of V7.
An alternative that I suggested in the topic with Karsten was using QT Player to convert to PAL after exporting out of iPhoto. It creates a larger file but if you're going into iDVD it will be encoded again. The extra encoding may lessen the image quality but you'd have to give it a try, save the iDVD project as a Disk Image (File->Save as disk image) and play the disk image with DVD Player to see how the encoding went before committing to disk (burn with Disk Utility at the slowest speed available).
Happy New Year
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
Note: There's now an Automator backup application for iPhoto 5 that will work with Tiger or Leopard.

Adobe Media Encoder only using single core of CPU (core parking has already been disabled and did not solve the problem)

I only edit videos every few months and the last time I edited a video was around 6-9 months ago. At that time, I noticed AME was only using a single core of the CPU and contacted Adobe who instructed me to disable core parking, which worked. After disabling core parking AME used 100% of all 12 logical cores to process the video and all was good. Then last week, I decided to edit another video and noticed AME was very slow and checked and it was again only using a single core to process the video, but core parking is still turned off. By slow I mean that a 10 minute video with the lens distortion correction preset and one video transition effect is estimated to take nearly 3 hours to complete. For comparison, the GoPro software processed the same clip with the same effects in 20 minutes. Also, through troubleshooting with Adobe over the last few days, I have also tried downloading previous versions of the software but the prior versions have the same issue.
The video I'm trying to edit was shot on a GoPro Hero 4 Black with 1080p Wide at 60 frames per second. The default video format for GoPro is .mp4. The output settings I'm using when I export from Premiere Pro to AME are H.264 with the YouTube 1080p HD.
My system:
ASUSSabertooth X79
Intel core i7 4930k (6 physical cores, 12 logical cores)
16GB DDR3 Quad channel RAM
Samsung 830 SSD 128GB
NVIDIA GeForce GTX 460 (not CUDA compatible, I know)
Please ask if you need any additional information to help solve this problem.

This has been driving me CRAZY... so going over the message boards from 2 to 5 am this morning I found the best explanation I have seen. The problem is that Adobe Creative Cloud is NOT "Processor Group Aware". Windows parses any more than 36 cores into "Processor Groups" and while the Pro version of Windows 7 & 8 can handle 256 threads they have to spread them across multiple processor groups.
Simple Version: AREA | How many cores does 3ds Max support?

Windows XP Mode (Virtual PC) only uses half a CPU core/thread.

Not only does windows xp mode not support multiple cores, to me it looks like it only uses half a core/thread.
I noticed this because I just setup windows xp mode (virtual pc) on my computer. I updated it, joined it to our domain and then installed our legacy ERP software. This ERP software was designed and programmed to run on windows 98 or 2000, I can't
remember right now, but its hardware requirements are very low. This software runs very slows in the virtual pc, with the processor being the problem.
Matching the processor spike on the virtual pc using both performance monitor and task manager I compared it to task manager running on the host (my windows 7 machine). The spikes in cpu matched one of the threads on my i7 processor (I use threads
because an i7 has 8 threads but only 4 cores). To my surprise when the CPU reached near 100% on the virtual PC the same spike on the host was only about 50% of the cpu thread.
The host has a i7 950, 3.07GHz processor. So this means that the virtual pc can only use up to 1.5GHz. I have not run into the problem reported in other posts on this forum where the CPU is always at 50% or 100% on the virtual PC because when
their is no activity the CPU drops to 10% or less and stays there.
I will now have to use vmplayer, problem is having enough xp licenses for all users.
Was anyone else aware of this?

You can't use a half a thread. Windows VPC uses one core at 3.07GHz, there's no halving the speed of the CPU.
The only way WVPC would use a lower clock speed is if there is power management throttling the CPU speed down. Do you have a power management setting throttling your CPU? Are you sure the problem is the CPU and not disk or network related?
Task manager on the host is not a very accurate way to determine CPU usage of the VM.
If you have the correct version of Windows 7 (Pro or higher) there are no issues with XP Mode licenses, you get one license included with Windows 7. There's no restriction requiring you to use XP Mode with Windows VPC, it will work under 3rd party
virtualization solutions.
