Playback is choppy / slow while speeding up clip anything above 200%

Coming from using Final Cut Pro X for a while, ive just bought myself a new laptop.
Basic Specs are:
Intel i7 3840QM 2.8ghz with 3.8ghz turbo
32GB Ram 1600mhz
1TB SATA 7200rpm in Raid 0
2GB GeForce GTX680M
Long story short, ive been a long time PC fan my whole life although using the mac only for video editing and being a basic macbook pro 13" with final cut pro x seems to outperform my newly acquired PC laptop.
I bought this laptop with the intentions to move my video editing platform back to a PC state and with the new Premiere cs6.
everything is smooth and all that but the same issue i remembered about premiere back when i wanted to try it out in cs3 time. the playback for previewing video is slow and choppy.
i have to always "render" my video just to preview it smoothly which is very time consuming. I always thought because back in the day my laptop wasnt as good as my new one now so that was the issue and moved over to my mac which was great for video editing only.
but that mac has basic specs compared to my new laptop and still the preview is flawless and smooth with LIVE video previewing. i mean i can do speed duration changes of 10% slow down all the way to 1000% speed ups and watch my video that same instant after.
but with premiere if i do anything speed changes of more then 200% original frame time it plays fine for 2 seconds at that accelerated speed then gets choppy and slow.
I even changed the playback resolution to 1/4 quality and i get the same issue.
i wouldnt mind waiting for the render so i can see that smooth playback and determine whether i like it or not except when rendering my clips from my gopro which is recording at 60fps 1080 it takes over 15 minutes.
This has always seemed to be an issue with premiere for me and am wondering if there is something i am missing here..
anyone point me to the right direction?
im not hating on PC or adobe at all, i love these two platforms in every other way but when it comes to this editing all i hear is good things about them but when i go to use them for myself its extremely frustrating.
P.S. yes i have set my GPU to use the mercury GPU accelerated mode which did minimal difference with playback smoothness.

I was having this issue last night while going through a bunch of 1080p 60fps footage I took yesterday with my Hero3 Black. I wasn't doing any speeding up or down, just previewing footage to cut sections out. It would play back fine for 6 seconds, then get choppy which got worse the longer I let it play. It played fine for 6 seconds after each pause and play.
I used Cineform as mentioned to convert the files which are now huge but play back without trouble. A 13 minute 2.8GB file became 25GB.
Hopefully this issue gets fixed so I don't have to go through all that.

Timeline shifts when I when I slow or speed a clip

How do I stop the entire timeline from shifting when I change the speed (from the Modify menu)? If I make the clip slow motion, it enlarges and every track shifts to the right. I just want a particular clip to enlarge and everything else in the timeline to stay put. Help?

In FCP 7 you can turn off the timeline rippling effect, in earlier versions you can't.
What I used to do (prior to FCP 7) was to select and copy the clip to be adjusted, move to the end of the timeline, paste the clip at the end of the timeline, adjust the speed to where I am happy, then trim the speed adjusted clip so that it is shorter than the original (by dragging the right end of the speed adjusted clip to the left), copy that and paste it back over the original clip, adjusting its duration to fit the edit.
Hope this helps.

External firewire hard drive reverts to slower transfer speeds

This is the strangest hardware problem I've come across. I'm running a unibody mbp (June 2009) with an external WD 2.0TB Caviar Green drive mounted in a firewire 800 enclosure made by icydock.
Lately, I've noticed that after an unknown amount of uptime, the speed of file transfers to the WD external drive slows down dramatically. I figured this out by watching my time machine transfers take a bit longer after awhile, and I verified this using aja system test and speedutilities.
When I boot my mbp in the morning, file transfers and time machine backups to the external WD transfer at a rate of about 67-75MB/s. This is the speed the drive should always be working at since it's connected via firewire 800. Aja speedtest verifies the speed is as it should be as well.
Then, after a couple hours of using my mbp, or even later in the day, I'll transfer a file to the external WD or run a time machine backup and find that the transfer will only run at a max of 29-35MB/s. This is exactly half the speed the transfer should be going at. Subsequent transfers stay at this slower rate no matter what I do.
However, I've been able to fix this problem by unmounting and remounting the external WD or restarting my mbp. After doing either of these actions, the WD external goes back to contant transfers at 75-80Mbs. So something is happening where the longer the mbp is running, or after some sort of disk activity, the external WD reverts to a slower transfer speed (closer to FW400). I can't isolate whether it's an issue on the mac os side or the hard drive or the hard drive enclosure because I can make the hard drive go back to optimal speed again merely by unmounting and remounting it. This works consistently until a few hours later when the drive begins to handle transfers at half speed again.
I run hourly time machine backups to the drive. The time machine backups can't be the culprit because the drive remains running at optimal speed after the backups (verified with aja system test and speed utilities)
Any possible ideas as to why the drive cuts down to half its optimal transfer rate after a bit of time? I can't figure out the cause of this, and the consistency of the drop leads me to think this is an issue with the power management on the drive since it reverts to full fw800 speed when I umount and remount the drive or restart my computer. Could this be an OSX issue where for some reason the system isn't negotiating the fastest speed?
Any help appreciated.

From the SoftRAID manual:
Fire hubs and disk drives. FireWire hubs are notorious for introducing errors and instability onto the bus.
Make sure that all of your consumer electronic devices (iSight, cameras, scanners) are connected to a separate FW bus. These devices are not built to the same standards as storage devices and known for introducing errors onto a FW bus.
Cables. While most cables work fine with a single device, many cables will introduce errors when 2 or more disks are connected to the bus.

How many thousands of Apple TV users have to scream their complaints before Apple will respond to the fury over the impossibly slow download speeds of movies bought through iTunes??????

How many thousands of Apple TV users have to scream their complaints before Apple will respond to the fury over the impossibly slow download speeds of movies bought through iTunes?

As jules says, your rate (currently at least) may be slow.
If it used to be good I wonder is your ISP is slowing ('throttling') your speed after you've used so many GB of a quota each day or month - check what they think you should be getting as a download speed.
While Apple's servers do occasionally play up, it's generally the ISP being slow not Apple.
If you're using Google's DNS servers that has caused issues for some.
Recommended speeds for near instant playback:
SD         2.5Mbps
720p      6 Mbps
1080p    8 Mbps
Is your speed test from somewhere like speedtest.net?
It might be helpful to post Mbps to ensure we/you are not confusing speeds by using different units to those measured.

WRT310N Playstation 3 Slow Download speed and general lag

Hey guys, I just recently bought the WRT310N and got both of my computers working with it. One is wired directly into the router, while the other is running off wireless. My Playstation 3 is able to connect to the router but I am getting an extremely slow connection speed.
Right now, both PC's get about 6.4-6.5 Mbps download speed while my Playstation is anywhere from 600 Kbs to 1.2 Mbps. I have plugged in my Playstation 3 directly into the modem and got a speed of 3.2 Mbps and was downloaded a demo very fast, but I do not recieve anywhere near those results when using it wireless.
Any advice? I have tried opening the ports, but that only seemed to slow it down. A couple of days ago I opened the ports specific to the game NHL 10 and for two days I was getting such a good speed in the game that it felt like I was playing offline, which was great! Then this morning, it just seemed do a complete 180. Now when I play the game I get an extreme amount of lag, and my other games like CoD4 get random lag spikes. Like, I'll be running and I get a lag spike which seems to happen fairly consistently every minute or so.
Any advice? Should I try opening the ports again or what?

I think you need to adjust the wireless settings of your Router, The wireless settings on your Router must have been setup to its default that's the reason you are receiving low signal strength on your PS3.
Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1 and press Enter...Leave Username blank & in Password use admin in lower case...
For Wireless Settings, please do the following : -
Click on the Wireless tab
- Here select manual configuration...Wireless Network mode should be mixed...
- Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbours network...
- Set the Radio Band to Standard-20MHz and change the Standard channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on Save Settings...
Please make a note of Wireless Network Name (SSID) as this is the Network Identifier...
For Wireless Security : -
Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WPA, For Encryption, select TKIP...For Passphrase input your desired WPA Key. For example , MySecretKey , This will serve as your network key whenever you connect to your wireless network. Do NOT give this key to anyone and remember the key.
NOTE : Passphrase should be more that 8 characters...
Click on Advanced Wireless Settings
Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304 >>Click on "Save Settings"...
Now see if you can locate your Wireless Network and attempt to connect...

FCP 7.0.3, 4x3Ghz CPU, 6GB Mem, RAID 10 but playback still choppy!

Hi, this is a bit crazy. I am editing a ProRez project and I would consider my MacPro reasonably powerful but when I play for 30 seconds or so the playback goes choppy. I have to stop and start and then get another 30 second chunk playing smoothly, then choppy again.
I am not playing on a external motor or doing any type of playback preview, I do have a Blackmagic Intensity card but am not using it.
I have checked all the drive settings (User/System Settings) and they are all pointing to the RAID array.
RAID conested to Mac with FW 800. I have done speed tests with blackmagic SW and got over 50MB/s read/write. Project is 22 mins. Format is ProRes 422. I am using Lion OS X.
Any ideas?
Ben
PS it now seems to be working a lot better but still cant play whole project.

Sorry, should have read your title more closely. Here's a handy reference doc on Pro Res specs. With respect to speed your setup should have no trouble. Do you have another drive you can use as a test media drive? Also, forgot to ask about available space on systems drive.

Mac Pro slow write speed on Samsung SSD drive

Hi,
I am wondering why I get very slow write speeds on my Samsung SSD 840 Series 250 GB system startup drive in my Mac Pro (early 2008).
I get an average write speed of approx. 35 MB/s and not much more for top speed. I tested it by transfering a large file (8GB, .m4v) from my Mac Pro internal Raid 0 (4x 2TB Stripe Set) delivering up to 550 MB/s. The read speed of the SSD is around 270 MB/s which I consider to be OK for that I have just the 3 Gb/s internal SATA interfaces in my pretty outdated Mac Pro.
I don't see any Memory or CPU overruns or consuming system tasks while doing the tests and no other user programs except Activity Monitor is running. The following screen shots from the Activity Monitor should proove my findings:
Setup:
Samsung SSD 840 Series 250 GB (SATA 6Gb/s and 3Gb/s compatible) system startup drive. Free Space left on SSD is around 100GB of 250GB.
Mac Pro (early 2008, Model 3,1), 2 x 2.8 GHz Quad-Core Intel Xeon, 8 GB RAM, NVIDIA GeForce 8800 GT 512 MB.
OS X Mavericks 10.9.1
Samsung sais there should be 540 MB/s for Seq. Read and 250 MB/s for Seq. Write for their SSD drive.
Any hints what could be done to increase especially that low write speed of around 35 MB/s (average) on the SSD in my Mac Pro?

Really great 'The hatter' !!!
Thanks a lot for your exceptional support.
Next to my 4x discs in the 4 SATA II drive bays I have installed a additional OWC drive kit that allows me to have another 2 disks sitting in the empty bay below the CD/DVD drive and those are connected to the motherboard. So there is a lot to handle for that controller you mentionned ;-)
I will follow your guidance and boot from my 'maintenance' system on direct attached external drive, install the TRIM Enabler there as well and do the DU repair run. I always have a separate system available that gives me the chance to boot my Mac from there. And in addition I regularly use ONYX to keep my OS X clean and do the maintenance.
Anyway, you're the man of the day!
PS; I am looking forward to finally receive my new Mac Pro (late 2013) ordered on the 18th of December one of these days and then I hope that I can fly ;-)

Test bed : WLC makes slow WLAN speed vs. Autonomous

Hi experts,
User complint very slow download speed (~140kbps) compare to wire around ~50mbps. Those are too different.
So I move out from the production, then did my own test.
I tested on seperated environment, seperated AP(1130)/switch/ WLC(7.0)/PC client with Windows file sharing. Then compare againt STANDALONE AP. All are flat configure without any Auth etc.
Result are, standalone AP is winner = 5MB/sec while WLC based is only 1MB/sec. Then I also try to do LOCAL SWITCHING (H REAP) to diable tunneling that could make some delay. Result is the same, no improvement.
I also find out for cisco support forum. Much many discussions ask us to disable feature such Client exclude, MFP, Aironet IE and tune for a/b/g supported.
What else to tune or aware of ?
Please do me a suggestion. Thank you.
Nipat.p

David,
Do you mean Static&Dynamic CH? I used default WLC's setting (Dynamic, DCA)?
Anyway, my testbed is using only 1 AP in 2 scenarios WLC-based vs. Autonomous at the same location.
I also asked from the others end user who is using WLC. Windows file share speed is also around 1-2.4MB/sec. So poor!!!
Then, What else for WLC parameter should I take care of? I got a slot to re-test by tomorow.

Itunes choppy, slow since upgrading to 10.x

I've updated quicktime to version 7.x still didn't help. It doesn't appear to be CPU or Memory related as the system is running at CPU levels of 25% utilized and memory is about 50%.

Hi and Welcome to Apple Discussions...
Try emptying the cache and reset Safari and see if that helps.
From the Safari Menu Bar, click Safari / Empty Cache. When you are done with that...
From the Safari Menu Bar, click Safari / Reset Safari. Select the top 5 buttons and click Reset.
If you are running Safari in 64 bit mode, try running in 32-bit mode instead. Right or control click the Safari icon in the Applications folder, then click: Get Info In the Get Info window click the black disclosure triangle next to General so it faces down. Select 32 bit mode. Also, (in that same window) make sure Safari is NOT running in Rosetta.

WAP321 slow download speeds

Hi!
I have a WAP321 access point in a home environment, powered by PoE, and sharing two VLANs with VAPs, one home network, and one guest network.
The problem I have is that my download speeds are very slow, while my upload speeds are fine. I usually get around 20-40 Mbps down (access point to device), and 60-70 Mbps up (device to access point). This is tested both with speedtest (I have 100/100 fiber) and iperf on the local network.
I am happy with the upload speeds, and would like to have similar download speeds.
The only thing I can think of that would have this effect is QoS, but I can't find a way to turn QoS off completely. I don't really need QoS at this point. I have these QoS settings right now:
I need to use mixed n/g mode for compatibility, but I have tried 5 GHz and there was no difference. I have also tried different channels but found that channel 6 that I was already using was the best. I have also tried to use 100% transmit power with no difference. 20/40MHz was slower than 20 MHz.
My diagnostics file is attached. Any help would be appreciated.

Best way to change speed of clips

Hey, I want to change speed of clips, both faster and slower in one clip. What is the best way to do that preserving the quality? I am still learning FCP so my apologies, and I had a hard time finding anything on here through search.

Jerry's right...
Take a look at this:
http://homepage.mac.com/captmench/SlowMo3.mov
Two frames each of FCP and Shake at 50%. Use your arrow keys to go frame by frame. First frame is normal, second is interpolated. Look at the background!!
Creative cow should have the whole tutorial online soon... I'll post back with the link when they do.
Also, for time remap -- shake's got that under control too... but for now, look at this:

I'm with Sky, and have had very slow broadband for a while now. Above are the statistics from the test socket. Sky seem to think there is a problem with the line. I've now plugged the router into the main socket.
Any help would be appreciated.
**EDIT** My phone line is with BT, my broadband is with Sky. The problem Sky says is with the phone line it seems.

Hi Joe,
Try sticking your telephone number into this line tester page and let us know if it finds a fault. If it comes back clear, you'll need to go back to Sky as there'll be no issues with your telephone line. If it comes back with a line fault, we can get it progressed towards a fix

Slow Broadband Speed

Hello Whom May Consent
I have just found out that I am not the only one have problem with BT broadband speed. Many people seem to have problem with their slow Internet speed due to the exchange problem. That’s good, because after 10 calls to BT, I still don’t know what the problem with my broadband. So let me tell you what the problem is.
My Internet speed suddenly got very slow (0.4mb) since the morning of 05/11/2010. I thought this was just temporary problem with the Internet speed and nothing should be worry about. The next day, I still face the same Internet speed (0.4mb) which is ridiculous when you pay 25 pound per month. Therefore I took action and made a call to BT customer service. I am sure I dial the right number to an “ENGLISH” company and somehow the line goes to INDIA. Strange~~~
The guy on the phone question me 10mins to check my identity and ask me lots of stupid question like have you try to connect your computer with wire instead of wireless or have you try to change the filter for my Internet connection etc. In the end, the India guys on the phone told me after 24hours my connection should back on the normal speed (5mb). Guess what, it didn't’t.
Clearly I was very angry and made a call back to “India” again to find out that was the problem with my Internet. This time the India guy on the phone seems to know the problem and very helpful. He told me that there was engineering work by my area on the “BT Infinity” which slows my broadband down and this work should be done by Friday 12/11/2010. The India guy even made a promise that he will call me back on Saturday morning 13/11/2010 to check the Internet speed.
Guess what, the India guy let me down. Not just he breaks his promise that he didn't’t call, my Internet speed is still 0.4mb. I was so frustrated at this point and made the call to BT for the third time. I went through the same procedure (10mins of ID check) and this time India guy told me there is a problem with my local exchanger and will get the engineer to fix it. Again, he promised me that he will solve the problem within 24hours.
Sadly the problem is still unsolved. I called BT again. The India woman on the phone told me this time she need to send an engineer to my house on Tuesday on 16/10/2010. At this point I was so angry that I said something very bad to the India woman (I am sorry) but still agree to wait for the engineer to come to my house all morning (missed all lectures).
Long story short, engineer comes and nothing has changed and today 20/11/2010, the engineer comes again to try and solve the problem with my Internet speed. What all his done is change my telephone filter and nothing has changed. Internet speed is still is still 0.4mb. I have been told by the India guy on the phone after the engineer visit that my line is been investigated by the engineers and the engineer will call me tomorrow 21/11/2010.
I just hope this time the problem can be solved otherwise I will cancelled the BT broadband and get my money back for this month’s broadband usages.
PS if they charge me any money for the engineer visit, I will make sure who ever pickups my complain call to feel suffer

Its been almost 2 Weeks...SLOW DL SPEED

My download speed has been really slow recently. my package is 20/5 and now im getting 0.4/2.6.
Whenever I called customer services, they asked me to do the same things. (reboot your modem, turn off your computer, go to speedguide.net, and optimize your setting and so on and on...)
Some of them admitted that they have a problem and others did not. I think that they have been received some complaints and they know about it but they couldnt pinpoint what exactly caused this.
I called them 4 times already, and they keep saying that i should wait and see.
Yesterday I researched some other FIOS forum, and I found In northeast area some people had been experienced the same sluggish download speed as I have.
These people said after verizon's ONT firmware update, they all having slow download speed. and they called technical support and tech guy sent some command and reboot thier ONT. and it was fixed.
So I called yesterday and explained the situation and asked for "hot fix". but she could nt understand the situation and kept saying wait and see.
she even said "hot fix is for Microsoft products."
humm... What shoud I do??

They mentioned that they had to implement a "hot fix". That almost sounds like a software patch, is that what that means or something else. If we gave you the group ticket number, could you look it up and see what they did?

I called FIOS services center and asked for hard reset on my ONT and they did...no improvement.
they keep saying no problem in thier network...hummm...
I tried 100 full duplex setting change as one guy suggested...no change...
During some research thru internet, One thing I found is that there are quite a number of people who have the same problem as I have.
here is a link for messages.

http://www.dslreports.com/forum/r21208319-northeast-BIG-Drop-in-dl-speed I
'm having the same problem. I think mine started early last week also.
I'm getting extremely horrible download speed, from only about 100kbps to 700kbps, on sites like microsoft.com, adobe.com, nvidia.com, giganews.com, ftp.netscape.com, etc. But my upload speed doesn't seem to be affected at all as is shown on speedtest.net. The download speed is so bad that even regular web browsing is somewhat affected.
FIOS tech support said it could be a hardware problem somewhere in the Verizon network and they'll try to pin point it and call me back in 48 hours. I'll call them tomorrow night if I don't hear from them.
The reason for him to say that is because while most places I'm getting horrible download speed, speedtest.net does show that I'm getting full 20Mbps down and 20Mbps up on a few of the testing servers. And while I was going to Trendnet.com to download drivers for my wireless usb adapter, I found that on »downloads.trendnet.com/ I can download at full 2.2+Mbps like I use to be able to.
Hey njchoochoo, try downloading this file and see if you're getting full download speed like you had before.

If you do, then we're basically having the same problem and I believe there should be more people out there with this.
