Quicktime playback very choppy

Hello,
I have recently purchased a MacPro (late 2013, 8 core 3GHz, 64 GB memory, OSX 10.9.2) and this morning it started playing video very choppy.
First off, there were some mp4 videos on my drive that all of the sudden I'm getting an error message that Quicktime can't play them. Almost as if a piece of software had gone missine or a bad upgrade (which I haven't done in the last few days).
The .mov files I have gotten to play play alright if they're very small files.  Anything else will play for a bit )10-30 seconds) then first the audio starts cutting out then the video starts to get really choppy. It's like Quicktime is running out of memory, but that can't be the case with 64 GB.
Additionally, and possibly related, work in FCPX has slowed way down to about half the speed of my retina MBP. Could a video card have gone bad?
Anyone have any suggestions?  Thanks!

also, if i put the video on an external hard drive, it runs fine.
Interesting ... fairly rare sort of problem, but it might be worth checking if the new drive is currently set to PIO rather than DMA. There's information on how to switch a drive to DMA in the *Modify your System Drive Configuration* section in the following document:
[Troubleshooting iTunes for Windows XP and 2000 video playback performance issues|http://support.apple.com/kb/TS1386]
(iTunes uses QuickTime for video playback, so a lot of the same basic troubleshooting principles apply.)

  • HD rental video playback very choppy

    I just rented the Rum Diary on my apple tv, it was playing fine until about an hour into the movie then the video got very choppy.  I tested my internet speed, it was just under 11 Mbps, can anyone tell me where i can file a complaint about this?

    Hi,
    Same problem with same type series 6 Samsung TV about 2 months old.
    Problem is most noticeable during fast pan scenes or anytime 2/3of the screen is doing something. Chunky, chunk, chunk.
    So the trick is to just turn off all the Samsung Motion Plus stuff off?
    I'll dig thru the menus and see what I can find. Is this something Apple can address?

  • Quicktime plays very choppy

    I have a kodak easyshare camera and when I put the videos from my camera on my computer it goes to MOV format. When quicktime is trying to play the video it plays very slow and choppy. ANd you really can't watchit that way. I don't know how to fix this. My camera records in HD, i don't know if that makes a difference. How do I play my videos on quicktime? Or how do I make it so I can play it on something else? Media player does not recognize the MOV format.

    I'm having a similar problem on a PowerBook. I noticed the problem after downloading the QT security update. After experiencing the problem, I opened the same .mov files in RealPlayer and did not experience the same problem. It appears to me that QT is not playing the files at the proper FPS rate. Frustrating.

  • Keynote transitions and quicktime movies very choppy, not smooth

    When playing a slideshow, my slide transitions and Quicktime movies are not smooth, especially when using Magic Move for a transition. There is also a long delay for the start of a transition, even if delay is set to zero. I believe I have adequate hardware but any suggestions are appreciated.
    Oddly, if I export a Quicktime version of the presentation or view in "Rehearse Slideshow," all transitions are smooth. Any tips for better playback performance while in Keynote? I would use the exported QuickTime for the actual presentation if there was a way to automatically stop/start playback at the end of each slide. Is there??
    Tech Specs
    Keynote version 6.5 (2110)
    OS X Version 10.10
    MacBook Pro (Retina, 13-inch, Late 2013)
    Processor: 2.6 GHz Intel Core i5
    Memory: 8 GB 1600 MHz DDR3
    Graphics: Intel Iris 1536 MB

    A number of recent posts have reported similar issues, all running on MacBooks.
    I have not experienced these issues on desktop machines.
    Try deleting Keynote, empty trash then install from Mac App Store
    When playing Keynote, close all other open applications.

  • Very choppy playback for Flash Player in all browsers

    I'm new to this forum but I hope someone can help me.
    I'm running Windows 7 Professional 64-bit with a AMD Phenom II x4 965 BE CPU and 8G DDR3 1600 memory on a MSI NF980-G65 mobo. All of a sudden today Flash Player (v 10.1.85.3) started very choppy video and playback. This happens on both Firefox 3.6.10 and IE 8 v8.0.7600.16385. I tried reloading Flash but it still is acting up.
    Any ideas?

    Internet Explorer uses ActiveX Controls for Flash Player.
    Firefox uses a plugin for Flash Player.
    Each must be installed separately.
    Chrome comes with Flash Player preinstalled; it doesn't need to be installed.

    Hi, thanks for the screenshot and info. Your Flash files for IE & FF are correct along with the Shockwave Flash plugin for FF.
    Did you find the Shockwave Flash Object in addons for IE to make sure it is Enabled? Check all categories. It is in Run without permission and All add ons.
    Also you may want to make sure your graphic and video drivers are updated to the latest versions. This site has some of the Vendors listed and that may be helpful and it gives information on hardware support.

  • I have Adobe Elements 9 and I used to be able to export HD 1080p videos with no issue. But recently, when I export using H.264 MPEG or MPEG 2, which I normally used, the high resolution videos come out very choppy.  How can i fix this?

    mr
    Are you running the 9.0.1 Update of the program and on what computer operating system is it running?
    Is your video card/graphics card driver up to date according to the manufacturer of the card?
    Is your computer optimized, including maintenance of pile ups of preview files, conformed audio files, and conformed video files?
    Do you have the latest version of QuickTime installed on your computer with Premiere Elements 9.0/9.0.1?
    What are your project settings and what are the properties of your source media? When you say that "used to be able to export...." is that on the same computer, same brand/model/settings for the camera recording the video now in use, same Premiere Elements 9.0/9.0.1?
    Where player are you using for the playback of these exports?
    Please give us more details on the size of the projects (then and now) as well as details of the customized export settings in your Share/Computer/ route. Premiere Elements 9.0/9.0.1 is only a 32 bit application running in 32 bit or 64 bit system. Not sure if computer resources might be taxed more so now than before.
    More later.

  • Quicktime playback is terrible

    My quicktime playback is terrible. I have quicktime v7.4.5(v25). The picture is unclear, pixelated, and very choppy. I am trying to play videos from my Kodak digital camera and streaming videos. I tried downloading flip4mac and VLC. I got nothing from these. Maybe this computer just doesn't have enough juice. If anyone can help at all please let me know. I am on the edge of buying a PC and going back to windows.

    Yeah just check out www.forum-snowboards.com. Their homepage has a video playing in the background and my computer plays it in clips like a slideshow. The other videos are from my Kodak digital camera that are about 10MB, 20 seconds long, and 640x480.

  • Timeline playing back very choppy over multiformat video.

    Hi Guys,
    I am editing some behind the scenes footage for a movie our studio is making. A lot of the media has come from different sources. Some red, some mpeg4 etc. The Mac i am using is a Quad Core Mac Pro... technically it should be powerful enough to play over all these fine. But even when everything is rendered, it is very choppy. So much so, that to check my audio is in synch for some of the action shots, i have to export it as a Quicktime and play it back and check it that way.
    Now i have tried RT in unlimited and safe... but it still happens. Does anyone have any possible solutions at all?
    Any help would be much appreciated,
    thanks in advance.

    Please give your full system specifications, what computer, what drives, what camera or deck, how everything's connected, what settings are on the media, what settings you're using in Final Cut, and finally what version of the software, of the OS, and of QuickTime you are using.

  • Quicktime playback issues in windows 8

    For some reason quicktime files are choppy and jittery during playback in Windows 8.
    I have the latest Quicktime installed with no other codecs.
    I tried playback in the quicktime player as well as in adobe products (premiere, after effects, etc.).
    Here's a preview of what the playback looks like:
    youtube.com/watch?v=BghtZznedvo
    The same rotating star video plays fine on my windows XP machine.
    I know this is not an Adobe problem but I was wondering if anybody had any ideas?
    -Pete

    That would be great if I could get away from Quicktime, but unfortunately Quicktime is the industry standard. I produce stock videos and animations and the stock sites only accept quicktime format.
    Maybe I'll wait until Oct 26th and buy the retail version of Windows 8 and then do a complete re-format, etc.
    It's weird but it doesn't seem to matter if it's an H264, Photo JPEG, or Photo MPEG encoded Quicktime file.

  • Very choppy animation when maximizing window on some movies

    Hi when playing some movies using Quicktime X and Perian, when I click the maximize window, the animation is very choppy. Sometimes the dock won't even disappear. On movie trailers it's perfectly smooth though. Is this normal? thanks

    Anyone else have this?

  • Very choppy video

    When using QuickTime Conversion to output to 1920 x 1080 and/or 1280x720 using the default settings within Options --> Settings (save for changing the quality to 'High) the output of the finished video is very choppy. Now using an Intel-based iMac with Leopard, I hadn't seen this before with my old (R.I.P.) G5 and Tiger. What changes should be made within 'Settings'?
    Perhaps while not relevant, the settings within Easy Setup are as follows:
    Use: Apple Intermediate Codec;
    Rates: All Rates;
    HDV-Apple Intermediate Codec 1080i60.
    This is frustrating to say the least. The video as input from the source camera is fine. I.e., no frame drops, etc. The source clip plays fine in QuickTime.
    Many thanks.

    Tom,
    When viewing the video it appears that it's skipping frames; the video is not smooth or 'fluid' if you will. These are of Diesel Freights being taped with the train moving perpendicular to the shooter and one can see them 'skip' or 'jerk' when viewing the video.
    The computer is an 20" iMac, 2.66GHz CPU (Intel Dual Core) and was purchased in January, 2009. (Right before, for the same money, one can get a 24" screen, 4GB RAM, and 2x the hard disk, standard. Of course. Anyway...). There is >135GB of available disk space on this systems 300GB Disk, which is formatted OS-X Extended (Journaled).
    Noteworthy is that Videos that were exported on the G5 I had are not showing this problem when played on this iMac. Only those that were exported from this iMac. Also, when the video is viewed within the canvas it's very smooth. So I wonder if there is something awry with the export process?
    Is it worth reinstalling FCE? I ask this also because you had mentioned not seeing multiple choices for output formats such as I see and had provided the link for. E.g., the ability to export at both "HD 1280x720" and "1280x720 16:9.".
    Thanks for your patience; I know this isn't easy to diagnose without having it in front of you.

  • Quicktime playback freezes all the time

    I have problems with Quicktime Playback on my Macbook Pro.
    Either Quicktime X or Quicktime Pro 7 seem to have this problem. 1080p Video's encoded by Compressor with H264 freezes (as in, does not respond to input, or if it does, it sometime takes 1-2 minutes before it reacts to a command given). It just doesn't respond to anything (and just keeps playing when playing) and the only way to stop it is to Force a Quit.
    It seems fine when just playing the whole file straight and do nothing.
    Sometimes it shows >>00X (>> as fast forward signs).
    This is very annoying, as it prevents me playing any video file I rendered and navigating through it.
    Anybody any ideas, or a tip how I can figure out what to do?
    Alternative players which run well on Mac?
    An example file can be downloaded from http://blip.tv/file/get/Dominicans-ReasonForTheSeasonAdvent705.mov (approx 215 mb)
    Any help is really appreciated!

    Actually, just testing that link I found that it was working fine
    Not sure which link you are referring to here. First is still broken for me and last works fine. I have no problem in either QT X or QT 7 on a Mac PowerBook Pro. File drops 60 to 80 percent of the frames to keep up on original PPC G5 DP model but this to be expected for 1920x1080 content at data rates pushing 5 Mbps.
    Can you be more specific as to what you mean by "not respond to input?" The only delay I get is when I jump the playhead beyond the range of the currently cached data and have to wait for the "download" to "catch up." This will also happen if your ISP connection is congested and the cacheing of data is slower than the playback data rate. You might also check to see how many "processes" you typically keep running. These can also slow your ability to process/play the movie. And yes, keeping multiple applications open can greatly slow down movie playback if they are actively working. (I.e., I would not expect to see much difference if FCP is idling but would expect a big difference if it is doing some "heavy" rendering operations. And even if idling, they system has to devote memory space to the app, as well as, waste cycles checking to see if you task them with some new activity. (Check you activity monitor.)
    As far as I can see, there is nothing seriously wrong with your file and since they play well on my systems, I can't offer much advice here. (I normally stick with Main Profile @ Level 3.1 and setting compatible with iPad/TV playback, but if you need Level 4.0, I don't see anything wrong here.)
