Choppy Playback of Videos

Installed iTunes 8 on an older PC (XP, 2GHZ single core AMD athalon, 512 RAM). The playback is very choppy and almost unwatchable. Theses are iTunes purchases as well. I've never had any issue with poor video playback before, but then again I've never tried to play iTunes store videos. I also noticed that itunes is using anywhere between 65%-82% of my CPU when playing these videos and ~53MB.
is this an iTunes 8 problem, or is my comp just not up to playing iTunes store videos.

I have the same problem here. Some research on older topics gave me this discussion:
http://discussions.apple.com/category.jspa?categoryID=149
It seems it was a know problem in previous ITunes versions. I have 3 PCS in my house, one with Vista and two with XP installed. In all of them video playback stops by 10 seconds of plaback, keeps freezed by 2 or 3 seconds, and then return. If we play video files in other softwares, like QuickTime, everything works fine. Any solutions?
Thank you.

HD video has choppy playback on timeline

Equipment:
New MacPro 2 X 2.93 GHz 6-Core intel Xeon
12GBs Ram
Nvidia Quadro 4000 2048 MB video card
Software 10.7.2
Video Card: Kona 3 with 9.0.3 driver & 9.01 premier plugin
Videodrive: 7200 RPM 2 TB internal (not the system drive) remaining space about 750 GB
Adobe CS 5.5 software
I just switched from FCP 7 to CS5.5 including a new computer which I perceive is optimized for CS 5.5. In playback my audio is choppy and dropping out some of the time, then if I stop and start the payback it will be fine, or sometimes there is no audio. doesn't seem to be any consistencey in what will happen the next time I start playback. On the timeline is a 1080i ProRes file I finished in FCP 7, then imported the video & audio file to Premier to make a couple of last minute changes. Program is 50 minutes long. I have the sequence setup as Kona 1080i compressed. I imagine I have missed something very basic here, but don't have a clue what it could be. Can anyone point me in the right direction?
Thx...Jim Watt

John,
I don't really think it's applicable in this particular situation. I have just switched to PP for FCP-7. All my FCP 7 shows are mastered in ProRes and this last one of course was too and it's the one I had to make a small change in. I didn't see anything in the post you referred me to that suggests that PP cannot/will not play back proRes material.
At the moment I'm screening DVCPROHD 1080i material and I'm having the same problem with choppy playback/freezes and lost audio in the viewer. I saw a post that came from Walter Biscardi for audio setup and followed that, which did seem to help a little, but the problem still exists. This is what i did...
Audio...set preferences in Premier to "built in output" and also set audio mapping to same, set audio hardware to "built in output" with caches at 1024
set computer preferences audio output to Kona card...
So I think this is some sort of setup that I have missed since I get identical problem with ProRes and DVCPROHD. Any other sugestions will be most appreciated. I'll give AJA a call tomorrow if I can't find a fix on the forum.
thx...jw

Choppy Playback - Video Card? Settings?

I am experiencing Choppy playback, I am using HD video recorded on a Flip Mino and a iPhone 4.
After getting numerous "dropped frames" warnings, I have transcoded my media to proxy video and still get choppy playback and dropped frame warnings (I have elected to turn off the warnings).
I have a late 2009 MacBook Pro with a NVIDIA GeForce 9400M with 256MB VRAM. 4GB of RAM.
I am selecting to use Proxy Video in my Preferences.
I use an external G Drive via FireWire. I realized I am on the low end of video card requirements, but should playback be this bad?
I have to export to a MOV file to actually see playback without the frame drops.
Is this unusual, or am I limited by my video card?

That drive will work best for video editing compressed HD with the eSATA interface. FW800 would also give you a few HD streams. But, if you use the USB2 or FW400 interface, you're not going to be much better off than using your single drive. That's called a "bottleneck."
Here's what you need to find out:
1. Estimate what the data-rate is for the footage you want to use. There are "data-rate calculators" all over the internet. Use Google.
2. Mulitply that data rate times the number of layers you want to play simultaneously in real-time.
3. Install a drive AND interface combiniation that exceeds the "Sustained Data Transfer Rate" for the number you came up with in #2.
Then, if you drop frames, it's not because of your drive (array); it's due to puny CPU or some other factor.
Some codecs strain the CPU more than others. Long-GOP codecs require more decoding to play back than intraframe codecs. Most DSLR footage is Long-GOP, and some flavors of it take 100% of all eight of the 3GHz cores in my MacPro to play back one stream. 2 or 3 is out of the question, no matter how fast my RAID is.
So, it may be that drive speed isn't your problem... you may have just maxed out your CPU's ability to decode that many streams of video in real-time.
But, if you do the math I just suggested, you can determine whether your drive is the issue.

ITunes 12.1 for Windows (64-bit - for older video cards) did not fix choppy playback

After reading all the other posts I tried installing the (64 bit for older video cards) and it did not solve my choppy playback with Music or Movies. I am running windows 8.1, Intel i7-4500U CPU @ 1.8GHz, 8 GB RAM, 64-bit OS, x64 based processor, DELL Inspirion 15. Never had problems until upgrading to 8.1 from 8.0.

Did you see if changing the Play Audio Using select in Edit > Preferences > Playback to "Direct Sound" resolves the issue? Otherwise you may want to consider rolling back to 12.0 and waiting until a future release is shown to resolve the playback issues in 12.1. See Turingtest2's notes on Troubleshooting issues with iTunes for Windows updates for steps needed to completely remove all installed iTunes components, and for links to the 12.0 installers.

Choppy playback/rendering for one camera in a multicam sequence

Any help is appreciated with this weird, specific problem...
I have a sequence (let's call it "MAIN") which contains many separate multicam sequences (let's call them "M1" through "M5"). Each of these multicam sequences is made up of footage from two cameras, a Canon 5D Mark III and a Canon C100. All footage in M1-5 was shot sequentially, and neither camera changed settings, although the cameras recorded with different settings from each other. The 5DIII recorded at 1080p 23.976fps. The C100 at 1080i 60Hz. This footage makes up all the assets in my project panel and they have no special media interpretation.
Here's the problem. Everything looks/plays fine until I get to M3 in my MAIN sequence. When I switch to camera 2 (the 5DIII), the playback in the program monitor looks about half the framerate of the original footage and all of my other sequences. Camera 1 plays smoothly. Camera 2 in any of the other multicam sequences plays smoothly (while in MAIN). When I open up M3 in the timeline, it plays smoothly. When I open up the original video in the source window, it plays smoothly. Everything plays smoothly but camera 2 in M3 (in MAIN) in the program monitor.
I rendered a clip of MAIN that has M3 cam 1, to cam 2, back to cam 1. Camera 1 is smooth, while camera 2 plays back at about half frame rate and looks interlaced. So this is a real problem and not just some display issue.
The interlaced look of the render made me think there's some sequence settings that were off, whether they were in MAIN or M1-M5. However, the sequence settings of M1-M5 are all identical, and the sequence settings of MAIN are not affecting any of the other multicam sequences.
I tried restarting my computer and deleting my cache. No dice.
Premiere Pro CC
Windows 7 Professional 64 bit
HP Z820 w/ 2 x Xeon E5-2630
128GB RAM
GTX-570
Addendum: After playing around with sequence settings a bit, but after resetting them to be all as they were, now M2 is giving choppy playback on camera 1, while camera 2 plays smoothly. What in the world is going on here?

The LEDs were reflecting on the book that the GoPro was on but I got it to work with a garbage matte using a frame grab with the lights off and including the book. It worked a treat! But I am going to remember the dark grey matte thing; less is more and all that. Thank you for your input, much appreciated. Ooh and as for multicam syncing I just nested the composite shot and used that as a single camera source.

Choppy playback with mxf files...

Hello. I have been working with Premiere Pro CS3 for quite sometime until just recently. Then last week I installed Windows 7, then Premiere Pro CS5.5 along with various updates. I usually work with DVCProHD (Panasonic), 720p, 60p. I just started working on a new project and playback is very choppy, whether the footage is rendered or not. Everything else works fine. My computer (purchased in 2008) has Dual Intel Xeon 5150 (10.64 Ghz total), 4GB DDR2-667 FBDIMM RAM (4x1GB), and an ATI FireGL V3350 256MB PCIe Video Card. I am using a dual monitor set up as I used to do with Premiere Pro CS3 and Windows XP (with no problem before I went to CS5.5). I checked the settings for the Mecury Playback and it seems to show that it is selected but also grayed out (can't be changed to anything else). Anyone have thoughts on why the choppy playback? Even Premiere 6.0 never gave me choppy playback like this. Thanks in advance.

> Exactly how much RAM is Premiere Pro CS5.5 able to use at maximum?
All of it. That's one of the reasons that we ported Premiere Pro to be 64-bit.
Are all files of all types giving you choppy playback, or just some? If it's only some files, then tell us as much as you can about those files.

No Playback on videos in the Project (PE9)

Hello
I need some help with a serious problem. I have been having some problems with Adobe Premiere Elements 9 for a while. Whenever I go to playback a video in the project the video won't play, but the audio will. This goes for what is in the timeline and the actual videos (not in the timeline) when trying to replay them in the program. Also whenever I move the marker (the thing that represents where you are in a video) if the video changes it is extremley choppy. Please help. I am running a Compaq Presario CQ56 Notebook PC with an Intel(P) Celeron(R) CPU 900 @ 2.20 GHz. I have 2.00 GB of Installed memory (RAM). I am running Windows 7 Home Premium. My system type is 64-bit. Please help.

1st, you need lots more memory... 2Gig is BARELY enough to load Win7 64bit... with nothing left over for programs
2nd, a notebook will usually have only one 5400rpm hard drive... you need a 2nd 7200rpm hard drive for all of your video files (see below)
3rd, depending on the type of file you are trying to edit, you may simply not be able to edit at all with a Celeron
4th, what is the type of video graphics adapter, and what is the driver version?

Now, at the same time and with the same hand... while still using the baton to conduct the orchestra... pick up a bow and play a fiddle... this would be doing something with your video file at the same time as all the other work
You as a person cannot do both at the same time with the same hand
A computer is a LITTLE better, in that it can switch from one kind of task to another very quickly... but not quickly enough for EASY video editing
You need AT LEAST two hard drives (separate drives, never a partition http://forums.adobe.com/thread/650708 for more) with Windows (or Mac OS) and software on your boot drive, and video files on a 2nd drive so the boot drive is not slowed down by trying to do everything

Choppy playback after upgrading to iTunes 11

I am still on OSX 10.6.8 so I can still use Front Row on my laptop. I just recently upgraded to iTunes 11 and now playback of video will become choppy and sometimes stalls and the sound will also become choppy and unsynchronized with the video. This occurs when playing video on iTunes or Front Row. Has anyone else experienced this and if so, have you come up with a solution?? Thanks in advance.

I was also having this issue on my iMac running OSX 10.6.8 after upgrading to iTunes 11. Clearing my user Library Cache seems to have solved the issue.
In case you're not sure how to do that, open a finder window, hit Cmd-Shift-G to go to a folder, then enter "~/Library/Caches". Select all the contents of the Caches folder, and hit Cmd-Delete. You will be prompted to enter your password in order to delete these files. Restart your machine and empty the bin when you log back in.

Choppy playback after burning data dvd in toast

Hi Ive just finished burning a copy of various short clips which I exported as a quicktime files from FCP onto my desktop then saved them as quicktime mov. through QT player which was successful enough.I then burned a copy of this QT movie in toast as a data dvd compatible for Mac & PC viewing.When I played the dvd in QT 7.4.5 the playback was choppy but the sound was fine. I then played the same disc on my G5 desktop running panther and QT 7.4.1 and it was absolutely fine.Is this process rather a roundabout way of doing things ? and what could be causing this choppy playback on my laptop?

Data DVD's and regular movie DVD are not read in the same way. A regular movie that is being read by your DVD player app is being stream too...and the player is set up to read from a DVD that way.
On the other hand a data DVD the data is just setting there...The DVD player can't send the video to Quicktime fast enough to play smoothly. That's why you need to copy the data DVD to the hard drive.
It would be if you had a 1gig image on a DVD and tried to edit it with Photoshop from the DVD. Photoshop would constantly bog down trying to read from the DVD while editing the image. Same if you had video files on a DVD tried and to it them from a editing app. The editing app not getting the data fast enough making editing very slow. Sometimes the program that's trying to read the from the DVD will freeze or crash. Best to copy the data from the DVD to the hard drive.

Audio waveform causing choppy playback

Having issues with nearly all Premiere cc 2014 (8.1) timelines where playback with audio track expanded to show waveform causes bad, choppy playback. As soon as i collapse the audio track playback is perfect. Not very useful when cutting interviews and needing to see waveforms.
Running a late 2013 mac pro 3.5ghz 6 core intel xeon e5 32gb ram all footage stored on a lacie 6tb thunderbolt.
Any fixes or help appreciated
Thanks

Everything's on the internal drive - a 320 gig 7200 rpm WD. Still has ~120 gigs free. The thing that's really getting me is that when I unplug the USB audio adapter, the video playback is fine.
There is an external drive for TM backups, but I just unplugged that to see if it was part of the issue and it doesn't seem to change anything.

Experiencing lots of audio stutters / choppy playback

With Adobe Flash Player in Youtube I am experiencing lots of audio stutters / choppy playback. The problem started happening only recently and seems to be getting worse. I am running Flash Player 11.2.202.208 in Internet Explorer 8 on Windows XP (SP3) with a pentium 4. I cleared my internet history / cookies. I did a disk clean up and defrag. I tried uninstalling and reinstalling Flash Player, and also turning off hardware acceleration in Flash Player. What else can I do?
Thanks.

Hi Daniel,
I think the best approach at this point would be to gather system information and open a new bug report at bugbase.adobe.com. Could you take a look at the following FAQ and gather the info needed and open a new bug report? Once opened, please post back here with the bug URL.
How do I troubleshoot and report problems with Flash Player Video?

Quicktime choppy playback

The Quicktime player works fine with 1080p video in full-screen mode but windowed it's choppy. Perhaps 5 fps for a couple seconds at a time, and 1 frame every three seconds the rest of the time.
CPU usage is 2% user, 4% system
VLC works fine full-screen or windowed.
I tried 32-bit mode. Still no good.
Any ideas?

Dear Ozcanuck
We also have a Sony Bloggie and experience problems with playback in iPhoto. I have found however that if you pay the videos through Slideshow in iPhoto they play a lot better without the choppy playback. You can turn off the background music so that you can here all the audio. It is a bit of a fuss but it saves exporting it and using up more memory etc.
I hope this solves your problem to some degree. it is annoying you can't just click play. It seems to be just affecting the Bloggie as my sisters lumix hd videos play fine with and without the Slideshow.

Choppy playback with QT 10?

Help! I am using Quicktime 10 to watch some videos. Video playback is very choppy, audio seems unaffected. I am on a Macbook Pro, OS 10.6.7. This problem just began a couple of weeks ago. I always do all the software updates recommended by Software Update, so did this problem arise from an update?

If you're still using the DivX 5.2.1 component it could be the cause. The authors acknowledge some issues with QuickTime 7. They also offer a "beta" version of newer software.
Another possible solution to choppy playback might be found in the Audio MIDI Setup app (Utilities folder). Set the audio output format to 44100 Hz and try the file again.

Choppy playback with specific user

Hi All-
I have an older Macbook Pro 2007, 2.4 GHz Intel Core Duo, 6GB 667 MHz DDR2 SDRAM, 10.6.8. I recently purchased a Nikon D800 and when I try to view the HD videos from the camera, it plays back choppy.
However, I created a new "Test" account on my Mac and it plays back perfectly smooth within that account. Do I need to migrate to that new account or might there be some settings or preferences that I could look to change in my original to solve the choppy playback?
Thank you very much-

How can I connect my iMac to a TV for playback of videos? My TV does not have HDMI.

How can I connect my iMac to a TV for playback of videos? My TV does not have HDMI.

You need to find out what video out you have on your iMac, and what kind of video inputs there are on your TV.
It will help to know exactly what model iMac and exactly what make/model TV you have.
Depending on the exact model iMac you have, it may have miniVGA, miniDVI, miniDisplayPort or Thunderbolt output. Your TV may have composite, S-video, component, DVI, VGA or HDMI inputs. Once you confirm what kind of ports your iMac and TV have, then we can probably suggest the correct cable or adapter so you can connect them to each other.
