Video Playback (Jerky)

My iPod classic 160 sometimes slows down when playing a video. The sound continues without a hitch but the video slows down to a crawl then catches up to where it should be. Does anyone else have a similar issue with their iPod and video playback?

I have the same problem occasionally (< 5% of the viewing time). There seems to be no pattern to when the picture starts to freeze while the audio continues normally. I have about 110 GB of videos on the i-Pod with about 20 GB of free space.
I just assumed that the processor was maxed and the iPod just bogged down. Open to any suggestions though.

Slow video playback - jerky video

Hi all. I'm having a problem with my Macbook. Its struggling to play Hi def videos either 720p or 1080p. This was never the case until very recently.The video are jerky and slow. I am aware that the majority of the issue is from the processor but like I said I never had this problem before.
I'm wondering if anyone else is experiencing similar problems and if they have solved it.

Hi Lyssa.
Unfortunately i don't have the original RAM Modules anymore. How would the additional RAM affect the playback speed? In addition to all this I am now in the Apple shop because my Mac won't go further than the pre login screen so I think the HD is gone. : (. The laptop has been relatively slow the last few weeks and this I think is the icing on the cake. I will let you know the outcome but appreciate the help.

Does anyone have problems with video playback, jerky video?

Video playback on my MacBook Pro is jerky, really not workable at all. Has anyone else had a similar problem?

This is my pet checklist for questions regarding FCP X performance - you may have already addressed some of the items but it's worth checking.
Check the spec of your Mac against the system requirements:
http://www.apple.com/finalcutpro/specs/
Check the spec of your graphics card. If it's listed here, it's not suitable:
http://support.apple.com/kb/HT4664
Make sure you're using the latest version of the application - FCP X 10.0.3 runs very well on my 2009 MacPro 2 x 2.26 GHz Quad-Core Intel Xeon with 16 GB RAM and ATI Radeon HD 5870 1024 MB. I run it with Lion 10.7.3.
Check that you have at least 20% free space on your system drive.
If you have not already done so, move your Projects and Events to a fast (Firewire 800 or faster) external HD. Make sure the drive's formatted OS Extended (journalling's not required for video). You should always keep at least 20% free space on the Hard Drives that your Media, Projects and Events are on.
If you are getting crashes, there is some conflict on the OS. Create a new (admin) user account on your system. Do NOT import any of the settings etc from the old account - simply use FCP X from there - if it runs a lot better, there's a conflict and a clean install would be recommended - but remember, if you reinstall the system, and then use Migration Assistant (or anything else) to import all your old settings etc etc, you may well be importing the cause of the conflict in the first place.
Keep projects to 20 mins or less (about half that for Multicam). If you have a long project, work on short sections, make them into Compound Clips and then paste these into a final project for export.
If you ever experience dropped frames, I strongly recommend you use ProRes 422 Proxy - it edits and plays back like silk because the files are small but lightly compressed (not much packing and unpacking to do) - but remember to select 'Original or Optimised Media' (FCP X Preferences > Playback) just before you export your movie, otherwise it will be exported at low resolution.
If you have plenty of processor power, for the ultimate editing experience, create Optimised Media - most camera native files are highly compressed and need a great deal of processor power to play back - particularly if you add titles, filters or effects. ProRes 422 takes up much more hard drive space but is very lightly compressed. It edits and plays back superbly.
Hide Audio Waveforms at all times when you don't need them (both in Browser and Storyline / Timeline). They take up a lot of processor power. (Use the switch icon at the bottom-right of your timeline to select a format without waveforms if you don't need them at the moment, then switch back when you do).
Create folders in the Project and Events libraries and put any projects you are not working on currently, in those folders. This will help a lot. There's a great application for this, called Event Manager X - for the tiny cost it's an invaluable application.
http://assistedediting.intelligentassistance.com/EventManagerX/
Unless you cannot edit and playback without it, turn off Background Rendering in Preferences (under Playback) - this will help general performance and you can always render when you need to by selecting the clip (or clips) and pressing Ctrl+R.
The biggest single improvement I saw in performance was when I upgraded the RAM from 8 GB to 16.

I'm downloading using RealPlayer But the video playback is jerky. The audio playback is OK.   Can anyone suggest a solution. Would upgrading to RealPlayer Plus be a good thing to do?

Please can anyone suggest a solution.
PS Would upgrading to RealPlayer Plus help?

I can't understand how internet speeds can be the cause of the problem. My problem with a jerky playback is that I have already down loaded.   Could this be to do with my computer (I maybe able to persuade my wife that I need a new one). Earlier I was listening to a clip of the MJQ, downloaded from UTube, and although the sound was good the picture was not.
My computer is an iMac with an Intel Core 2 Duo with a processing speed of 2.8 Ghz. Does this information help?

Jerky 6500 Slide Video Playback

The spec says it should playback video in QVGA(320x240) encoded as H263 or Mpeg 4 at 30fps. I just cant get it to play anything back without it being extrememly jerky and even sometimes losing sync with the sound.
Stupidly I would have expected the software provided with the phone (Ulead Video Toolbox Basic) which asked for my phone version during installation to at least make videos which can be played on the phone. I've had the video stop on several of them during playback, and they're always jerky.
I tried encoding things in SUPER, that also provides jerky playback. Does the phone need to be returned, or am I doing something wrong? Any ideas gratefully received.
Thanks :-)

I'm still on the quest to resolve my video playback issues. I recorded a video from the phones camera in it's maximum setting, 640x480 at 15fps, so i was kinda making the assumption that if I encode a video at QVGA 320x240, then because the video is a lot smaller it'll playback at 30fps.
I did an analysis of the video from the camera, and the interesting thing is that it has created a video using sound settings which I dont seem to be able to produce in any software, specifically it is using the AMR_NB with 2 channels, which doesnt seem to be an option with any encoder (including Super which is extremely flexible usually, in fact they say in their FAQs that it's not possible for this type of codec but nokia did it), does anyone know what can produce video conversion with these settings?

Jerky H.264 HD video playback

Hi folks,
I finally installed QuickTime 7.0.2 for Windows. Enough of those preview releases already... Anyway, trying to play back some HD stuff I downloaded previously is giving me problems. It's a new 3.0 GHz Dell and I tried to play the 720p version of Batman Begins. During playback the screen is jerky as if there is a resource problem (though the sound is OK). I checked and CPU usage is below 50%. I even tried re-installing, no dice. Finally I tried to play the larger 1080p version and that works perfectly. My only conclusion is that something's wonky with the PC version of the 720p HD videos (same thing with Fantastic Four). Now the videos play nicely on a Mac and in VLC, so it has me stumped.
Cheers,
Michael

I have H.264 video playback too. I am have tried vlc player and it plays a little bit smoother but still not very well. I have looked at my settings in quicktime but it hasnt helped. Anyone have some troubleshooting ideas???

No Hopes for SMOOTH Video Playback in Adobe Bridge ?

Hi....
System Specs
MacPro Nehalem 16 CORES
32 GB RAM - 4TB RAID0
Lion 7.2
I have a bunch of video files that I would like to organize via Bridge.
Works ok but video playback is a slap in the face. Looks like jerky slow motion.
I have tried altering from hardware to software rendering. No remedy.
Bridge has been around for a long while and with each release the app actually performs worse.
Menus are ultimately slow in showing up and entering a folder with 16 video files (QT ProRes),
selecting them all, has Bridge freezing for 5 minutes supposedly creating previews.
Completey unuseable for video.... in my world !
So my question is this...
Are their any plans for implementing Video Capabilities in Bridge
or is some kind of 3rd pty. plug-in available that will enable Bridge to playback what ANY other app incl. the QUicklook and Finder can Playback.
Funny thing is that this whole app has been created to BRIDGE between apps created by adobe. If Bridge was a REAL bridge I wouldn't dare cross it.

It has always seemed that Bridge has been the stepchild of Adobe since its inception and that Adobe spends precious little effort and resources on it.
Remember that Bridge was born as nothing more than Photoshop's Browser. Nothing more.
Then, in a straight marketing stunt, Adobe decided artificially to lump together a number of totally unrelated applications into artificial "suites." These are in fact totally non-related applications that were artificially bundled by fiat of bean counters and marketers. The engineering teams for the individual point applications are totally independent from each other and are not only not in in the same building but in different cities, different states and, some, in different countries. They have pathetically little communication among themselves.
The humble Photoshop Browser was renamed Bridge and jerry-rigged to serve as some sort of go-between vehicle among the applications also jerry-ringed into artificial suites. (Definition of JERRY-RIGGED: organized or constructed in a crude or improvised manner <a jerry–rigged plan>.
Don't expect too much from Bridge, and don't complain about it too loudly, or you might find yourself among others who have been told, in effect, that "Adobe doesn't charge you for Bridge." As a "free" byproduct, you get what you paid for.
In this context, just look at what has happened to the value of Adobe stock in the last five years: –28.20% (minus).
Compare that to Apple during the exact same period: +358.43%.

Video Playback in IE

Hi Everyone,
I'm new to Flash and am also experimenting with a Flash Media
Streaming Server. I am trying to get video streaming to work with
my new website, and the video so far plays great with no problems
in web browsers such as Firefox/Safari, etc.
However, in IE, the playback is noticeably worse. I can't
figure out why! I originally thought it was a streaming issue with
the server, however, this wouldn't explain why other browsers are
handling the stream better. Also, pausing the video playback and
un-pausing makes no difference, ruling out a buffering issue.
Every I.E. browser I try the below video in, the video is
jerky and not smooth. I should note also that if I try to play the
video directly through
http://flash-server.hermonsd.org/test/
(Streaming Server Test Page), it works perfectly in IE.
So I am concluding that the issue is with the compiled Flash
file used directly on the below link. I'm using nothing more though
than the provided FLVPlayback module that comes with the latest
Flash CS3 software. Does anyone know what I may be doing wrong and
what I can do to improve the playback quality in I.E.?
Example Video is here:
http://www.rihanna-online.net/videos/dontstop/DontStop.html
P.S. To avoid a possible flame post about copyright, the
website hasn't opened yet and tentative use for construction is OK
while the record label is reviewing the website to contact me
back.

With weeks of research, I found the cause of the issue. It's
not related to the media streaming server.
It appears there is a known issue with the WMODE function in
Internet Explorer and Flash. When I removed the WMODE code from the
HTML pages calling the flash, the videos played flawlessly.

Inadequate video playback from camera video

I have a Panasonic Lumix DMC FX07 camera. I took some awesome soccer video and was puzzled that I needed Quicktime to view it on my computer. I was sad to see that the video playback was horrible - all audio and jerky video. The video plays fine on my camera. So my first question is: (1) what's wrong with video playback? My second question is (2) do I seriously have to pay $30 to upgrade to Quicktime Pro just to save MY own video to my computer? I am obviously reluctant to do this if the free version of the software does not even work correctly. My computer is basic but I've upgraded the memory and other videos (streaming, my canon camera etc) work fine so please leave off the poor computer specs reasoning. Some honest feedback would be welcome as I am hopefully just not doing something exactly right. Thanks in advance!

I found a sample video from this camera on the web and it's working for me in the newest QT 7.6. I tried also mplayer and VLC player - both are able to play the video, so try them. You can also use them to convert video to another format (mplayer is just player, but it's shipped with mencoder that can do it).
If none of the players is working for you, try to post somewhere small sample video from your cam - I'll take a look on it.

ITunes video playback quality is not that smooth

Hello:
Two questions--
1. Why do the music videos I purchase on iTunes (and then play on iTunes) freeze up for a few seconds after I push play, but then otherwise playback is OK?
2. Why does the "spinning beachball" appear almost everytime I press play for a video?
Comment--
Given that my Mac more than meets the minimum system requirements for video playback, I think the videos should play smoothly from start to finish, especially at $1.99 a piece. I suspect that the playback bugs listed above are the result of iTunes not being that good/powerful of a video player. Hopefully, these issues will be resolved upon future iTunes software updates. In the meantime, I will not purchase anymore videos.
Thanks.

Just updated iTunes to most recent version. Now I'm getting jerky video playback in BOTH iTunes and QT Pro (latest version). CPU use is very high but random; ditto with video playback (i.e., doesn't hang up on the same scene/time).
I had this issue a little over a year ago after updating iTunes to the then latest version. Got nowhere with Apple's "Service" texts. I played around with configs for a while and also re-installed iTunes. It has worked fine until yesterday (same symptoms as last time). As for the past "fix": nothing I can hang a hat on. Methinks Apple updated the version I re-installed with (tho' the version # was unchanged).

Video playback problems [6500 Slide]

Video playback at 25, 29.9, 30 fps is jerky, only 12.5, 15 fps videos play correctly... Lowering the bitrate or using a less complex profile/codec doesnt help much. Funny thing is, it can play its own videos which are whooping 640x480 @ 25fps and 2000-3000kbps [for comparison: the videos i encoded were only 320x240, 25fps, 200kbps] without a problem! O.o So, why has it problems playing my less complex to decode videos?
I tried following ways of encoding in SUPER:
MPEG4
h.263
XviD (h.263/basic)
320x240
25, 29.9, 30 fps
AAC
2ch
44.1kHz
96kbps
All jerky! :[
But halving the fps... Viola, it plays fine!
Is this a known issue?
Will this be fixed in the next firmware? Hope so! >.
Cant nokia release some video coding tool with profiles for each phone model, to ensure flawless playback!? -.-
Regards, KD

I found the intel driver doesn't like xv output. In VLC go Settings > Preferences > Video > Output modules and set X11 video output. See if that works. If it does you can do similar things to totem using something in the gnome-media package (can't remember what exactly of hand...)

OS X 10.8 video playback issues

since upgrading to OS X 10.8 I have several video playback issues.
I have a lot of videos ripped to my Drobo NAS, connected bij FW 800 to my MacMini (4 GB, 2009). Until recently, playback was smooth, either with VLC or DVD Player.
Since upgrading to OS X 10.8, DVD Player is not playing VIDEO_TS folders anymore, all I get is a chequered screen. This is also happening on my MacBookPro and my iMac i7, so this is not a specific hardware issue.
After upgrading to OS X 10.8.2, videos are playing back jerky and audio is out of sync in VLC and QuickTime.
Since I have 10,000+ videos in my library, this is absolutely unacceptable
I tried reinstalling OS 10.8, and trashing the prefs, but to no avail.
please help.

Are you running the latest version of VLC player?

Hope this helps

Problem with audio configuration that affects audio/video playback

Recently, when I watch video on i tunes that sound and picture to not match up. Sound seems to be on-time but the picture is jerky and behind. I un-installed my video driver and reinstalled. Problem persisted. I started my computer in safe mode and it said there was a problem with the audio configuration that effected audio/video playback. I uninstalled i-tunes and re-installed and the problem still persisted. I'm at my wits end and it is driving me crazy. Windows Vista is automatically updated so that's not the problem. Please help.

Have you had a chance to look at this troubleshooting page? It may be of some help: iTunes for Windows: iTunes has detected an audio configuration problem

Built-in iSight video is jerky when recorded into iMovie.

Hello,
When I record video in iMovie directly from my built-in iSight, the resulting video is rather jerky - it doesn't look like the frame rate is slow, it's just that if I move my arm quickly, for example, while it may be a smooth motion in real life, the recorded video has little stutters in the motion, almost if some of the frames are out-of-order. I don't have this issue when using iChat - everything looks fine there. I have a MacBook Pro 17-inch (Mid-2009), with iLife '09, Mac OS X 10.6.7, 4 GB RAM, and about 100 GB of free space on my hard drive. Everything is completely up-to-date via Software Update, and I just ran Repair Disk Permissions in Disk Utility last week. The last time I recorded into iMovie, I didn't have any other applications running on the computer, and it still happened. The computer was sitting stationary on a table. I was using a professional microphone through a FireWire interface, and the audio recorded perfectly - it was just the video that had issues. The audio and video stayed perfectly in-sync the whole time, too. The video looked jerky in iMovie immediately after recording, and still looked jerky after being uploaded to YouTube. I've seen other people's videos on YouTube that exhibit this behavior, and they generally look fine if I go down to a lower resolution for playback, so I'm guessing I'm not alone - it could either be an iSight issue or an iMovie issue.

Sorry, I meant when I use the 'Q' command to put the video onto the storyline. I use the Import files to bring the files into my library of videos and it looks fine there before using 'Q' to stack the video onto the storyline. 99 percent of the time it works fine, it just has this flipped error when building multi-video composites, it has never happened when I build a normal video project.

.m4v videos play jerky with VISTA

sound is OK, but video is jerky. These have been purchased from iTunes and they worked fine with Windows XP. I've tried all the troubleshooting suggestions on Apple support site. Anyone else have a solution?

Take a look here and see if any of the tips help:

The suggestions for Vista are somewhat different than those for XP.
Good luck.
