Short video playback jittery

Greetings,
I started having a very weird issue since last two updates for firefox (currently showing 33.1) on my weaker machine. The videos such as posts marked as GIF (not actually gifs but seem to be short videos in mp4 or webm format) on the popular 9gag website started behaving strangely.
The playback became extremely choppy with the video skipping 2-5 frames backwards and forwards, making everything look like a pop music video. I cannot seem to find anyone else having this issue and after extensive googling and exploring the knowledge base I came up with nothing. Youtube works fine, no other machine so far has the same problem either. It makes no difference if I play the video on main page or open in a new tab. Resetting firefox did not help resolve the issue.
Sadly I cannot make a good screenshot to help show the issue as it only appears during actual playback.

Checked the xine engine options. It was already set to xv. I have never used anything but xv, so I don't know what changing this could do. Some settings don't work.
Grepping Xorg.0.log for EE gives me:

HELP! quicktime videos playback jittery: RAM problem?

hi, i'm hoping someone can point me in the right direction - i use veejay software to mix videos live and have this weird problme all of a sudden, where my videos play back jittery. i thought at first it was the software, but i changed software and though it was working fine before, now suddelny the problem has recurred....
i wonder, since the videos get loaded into ram, and play from there instead of the HD, could i have a ram problem?
thx for any help in this!!! i have a gig on the weekend and NEED to fix the problem...

Can you give some details on your system - What version QT, RAM, free space on HD, etc?
sorry, thought that was in the footer of the message.

Jittery video playback

I'm not sure where to post this, but I'll try here. Hope someone can help.
Lately I've been having issues with stuttering, jittery playback of video materials whether it's on Vimeo, Youtube, full episodes of television shows, HD videos, whatever. None are playing well. I called Verizon and they say my internet connection hasn't changed on their end in the last few months.
Is this a Safari issue? Has anyone else experienced the same problems?
Or do you think this is a video card issue? I have two 32MB cards - ATI VGA and NVIDIA GeForce1 MX. I recently bought a new monitor that's is 1680x1050 resolution. 64 MBs should be fine, right?
Mac OSX 10.4.11, Safari 3.0.4, Quicktime 7.6, Flashplayer 10

Hi,
There have been some posts that claim that repairing permissions can sometimes help with slow/jittery Flash video playback.
Run Disk Utility and repair permissions on your boot disk to see if that makes any difference.

How can i monitor network traffic to debug video playback issues from a NAS?

I am having problems playing videos on my new Mini that i am using as an HTPC.
I have a brand new Mac Mini running Lion with a 2.7 i7 processor and 8GB of RAM with a wired connection to a switch. .
My switch is a NETGEAR ProSafe GS108T-200NAS set to default settings. I haven't had a chance to start messing with VLAN settings or anything else. There is a bit of a learning curve on my part on this end.
My NAS is a ReadyNAS Pro (RNDP6000) with 3 x 1 TB hitachi ultrastar (HUA722010CLA330) drives and a 1.5 TB seagate (ST31500341AS) drive setup in RAID config using X-RAID2.
The problem I am having is video playback when accessing large video files off of the NAS. These are typically 1080 HD mkv files.
I have tested movies as small as 7.5GB with only slight stutters on occasion. I tried a 10.5GB movie and the stalling was much more pronounced. Movies larger than 11GB are completely unwatchable stalling every minute or so.
I have also tried large movies on the local drive and that is not a problem at all - they play back just fine. Beautiful playback in hidef. Mind you, some of these are the same files that were stalling over the network.
I have also noticed that some other network devices get kicked off the network when a movie is playing.
I think it has something to do with the transfer speed of files over the network and the switch - i am no expert at this mind you.
I am wondering if there is some sort of utility that i can use to monitor network activity on the mini so that i can fix my problem. Or has anyone made chages in their switch settings to optimize data trasfer speeds.
Any advice or recommendations on.
Thank you all!

OK, I did a couple of things and ran things a couple of times.
First what I did settings wise:
I enabled jumbo frames on the Mac Mini, ReadyNAS Pro, and the Netgear GS108T switch. All with MTU set to 9000.
I went ahead and enabled jumbo frames on the rest of the computers on the network just in case.
After these changes I ran into the same problems with videos timing out - very annoying and frustrating as you can imagine.
Then I started playing with device configurations. My original configuration was NAS > Netgear switch > Mac Mini. I went ahead and switched the switch to an Airport Extreme I have as my WAP and the setup looked like this - NAS > Airport Extreme > Mac Mini.
Well, long story short, no go. It appears to me that the NAS is the one having issues providing the necessary data at the proper speed. I also tried playing sopme movies off of the NAS onto a desktop i have and had the same issues - choppy frames and crashing movies. I even tried connecting wirelessly to see if that would work.
BTW, I have the Mac accessing the file system using CIFS.
I don't know what else I could do.
I am going to have to go to the Netgear forums to see if i can figure this out. Hopefully, I can get things going to be able to help some people out.
If anyone has any ideas, they would be greatly appreciated.
My only other alternative is spending $2000 for the thunderbolt capable NAS that Apple sells - it's only money!

Apple TV video playback stutters - even with SD

Hi,
i don't know what i am doing wrong, but i have some serious video playback troubles with my new atv:
All files start to play fine, but somehow - like every few seconds - the movie seems to stuck for a very short time - just an eyeblink. it looks quite the same when you play a HD Movie on a computer and the CPU is not really capable of playing back this files...
it doesn't matter if the video files are on the internal drive or streamed over wlan - same problem...
i'll tried lots of different software for the video converting: visual hub, handbrake, quicktime pro... always the same problem...
The strange thing is - all apple trailer movies playback just fine!!! even in HD - smooth as butter...
Please help me!
Thanks - Matt
my setup:
Apple TV 2.3:
720p - 60Hz
TV:
Samsung Le-40a557p2 LCD-TV
Sound via optical cable from aTV:
Sony DAV-IS 50

Assuming you're using conservative video encoding and not pushing things to the limit, I'd say something is probably amiss with the AppleTV.
If you were just streaming I'd look at the network first of all, but you say it hapens with synced files too.
Assuming you've pulled the plug and rebooted at some stage, I think I'd do a system restore (which will delete all media so make sure any purchases are transferred first), and if it was still an issue, then I'd get the new AppleTV replaced.
Occasional glitches happen but they shouldn't happen all the time.

Program Monitor is Black, no video playback after installing new graphics card

I bought a PNY Nvidia Quadro 2000 graphics card a few days ago, and since it's been installed, I've been unable to watch video playback in my program, source or even reference monitor.
Similarly, If I designate one of my monitors soley for video playback, the screen is just black, and as the timecode advances on my timeline I only hear sound.
My project is using "Mercury Playback Engine GPU Acceleration" for Premiere Pro CS6.0.1
I went from using one graphics card to using two graphics cards, and installed a third monitor. I've spent the last few days trying everything I could think of, I even uninstalled and re-installed premiere.
Hardware Specs:
Windows 7 Ultimate (64-bit)
HP Pavilion h8-1230z
AMD-FX8150 3.59Ghz 8 core processesor
16GB RAM
600W PS
EVGA Nvidia GeForce GTX 550Ti
PNY Nvidia Quadro 2000
I am using a PCI x16 for the Quadro 2000
I am using a PCI x1 slot w/x1-x16 adapter for the 550Ti
Could this be the problem?
Additional Information
Vectorscope, All scopes, YC Waveform - Display modes all work.
I downloaded the most recent Nvidia drivers for both of my cards.
I haven't received any error messages or had any problems in After Effects CS6, as video playback is working properly in my other adobe applications.

I am still building a new system, so currently I'm still using a 480. You can read all about my choices and progress here: Adobe Forums: Planning / building a new system. Part 1
There are 11 entries in the Benchmark Results that succesfully use the GTX 680, even though it is not 'supported'. They all use the 'hack'. However, the 680 has been added to the list of supported cards for AE, so it is only a matter of time before the 680 will be added to the list of supported cards for PR. Todd had made that clear. Now, when the 680 is added, it makes sense that the 670 will also be added. My guess is that both will be added in a short while.

IPhone4 help regarding video playback

Hello,
I'm not techno, so I am sure someone out there can help real quick!
Whenever I use my PC to playback some of the short videos I have recorded on my iPhone, some of the clips are upside down, or 'on their side', and I can't see how to rotate them back to the way they should be.
Help?!?!

This project concludes of four parts
1.Segmentation (Video to Image conversion)
2.Comparison (Copare frame using algo.)
3.Extraction (remove duplicate frames based on algo)
4 Summarization (Collect frames and form a new content based video)So, compressing that into a simple question instead of a convoluted one... you just want to remove duplicate frames from a video and save it to file?

Video playback speeds up automatically?

Hi all,
I have a number of short cartoons for my cousins on my iPod nano (7th gen), but the longest video is giving me some trouble. It starts off fine, but about 10 minutes in, it starts to play as if it was on fast forward. Is there some kind of length limit to the video playback for the nano? This particular file is 26 minutes long, while all the other files that play normally are under 8 minutes in length. Does anyone have any ideas where I can start to troubleshoot?
Thanks!

Not a clue about the problem, sorry, but can "imagine" a workaround just to fool the problem.
You must have a PLAY button that connect to that first scene (first chapter in the track, I guess). If you connect that button to the second chapter (just to try) that plays fine or again behaves as it was first?
If that way plays fine, you can add a "false" first scene (i.e. one second of black exported from FCP) and connect the PLAY button to the real first (now second in the track) chapter.
I told you, it's just a workaround to have in hand in case your dead line gets close!!

Video playback, Lumia 925

I searched for an answer to my problem and suspect I may have found the answer to want to confirm it. I have a short video clip (3 minutes) that I want to put on my Lumia 925. The video is in DV-AVI format from a MiniDV camcorder. The spec is standard definition PAL so it is 720x576, interlaced, with a frame rate of 25fps. Despite the Nokia spec stating that the phone will play back AVI it doesn't want to know. The spec also says it will play back mpg files so I have converted the file to PAL DVD compliant mpeg2 (720x576, 25fps, interlaced) with a bitrate of 8Mbps. The phone won't play that either. Now I am not a fan of high compression codecs but, as the spec for my phone says it will play back H264 mpeg4, I have converted it to that but retaining the original resolution and framerate. I tried the file as both a .mp4 and a .m4v but it still refuses to even acknowloedge they exist. I am copying the files to the Video folder in the phone but when I go to Music+Videos, Videos, it tells me there are no video files on the phone.
Could it be that the Nokia spec says the phone will play back 30fps so it doesn't recognise my 25fps files as being video? Only SD NTSC video uses 30fps (well, 29.97 actually) while PAL uses 25fps so why doesn't a UK market phone support the UK standard? I noticed that the video camera cannot be changed from the default 30fps either.
Solved!
Go to Solution.

I guess you could use something like handbrake. Also check this.

ITunes 11 HD video playback slow/choppy/stutter/skipping in OSX

Hi guys,
I'm running iTunes 11.0.1 in OS 10.8.2 on my 2.66 GHzm, 8 GB RAM MacBook Pro and playback in HD (1080p) movies/TV shows in iTunes is slow, choppy, stuttering and skipping. Can't seem to fix it. Any help would be greatly appreciated!
Thanks!

I was having this same problem, and found one cause.
I have an extensive library on a Drobo FS. None of the AppleTV's in the house have any problem streaming full 1080p from it, but my new iMac does. Choppy / laggy video play. Movies and TV shows right from the iTunes store. I can have 3 TV's streaming, and even a 4th laptop, all streaming from the iMac iTunes using the Drobo. They all have zero issues. No lag, no choppy, nothing. iMac has the issue even when nothing else is running. Every time.
BTW, it's happend on my old iMac and the brand new one, both with iTunes 11.
I was told to try setting up a second account on my iMac, and try playing video there. It worked. No problems at all. Weird.
So I started looking at differences between the new account, and my standard. I'd already made sure nothing unusual was running, and no processor hogs (not that anything short of Handbrake at full settings has come close to pegging out the processers on the new box). I found one thing, that made a difference. I had Timemachine backups, going to the same Drobo FS (though a different partition) turned on on the iMac.
Timemachine was running the whole time, and didn't impact any other streaming from the same machine, but it did make iTunes video playback of 1080p movies skip like my 6 year old daughter on the iMac. I turned it off.... no more skipping. I've watched 5 TV shows and 2 movies on that account, and not had another single incident.
Obviously, there is still a problem. The iMac and Drobo have enough bandwidth that they can do all the work at the same time (or I'd be seeing the problem on the other devices while streaming), but they are not playing well together on the same account. I've also checked the throughput to the Drobo FS from the iMac... way more than necessary. If it were a read / write thing on the Drobo, then I'd expect other devices to see the issue when I'm watching something on the iMac that is skipping, but there was still no skipping on any other device at that same time...
But, as I said, I found the root cause in my case. I can turn off Timemachine backups while I'm watching a movie on the iMac, or I can move where I write the Timemachine backups to (going to try this over the weekend to be sure it works). If moving the Timemachine backup to a different drive doesn't work, it's a bigger problem.
I'd really love to see Apple fix this and the issue where I have to turn iTunes on in 32bit mode when using an external library (of it gives the funky quicktime error until you delete and readd the movie).
Hope this helps some of you, if not all.

Video playback very slow/failing with both iGPU and dGPU enabled simultaneously

Until a couple of months ago, my PC was running with an i5 760 and my current Radeon HD 7850 on Premiere Elements 11 just fine - playback was smooth and I could edit my videos just fine.
However, recently I installed a new CPU and motherboard - an i7 4770K. The key feature here is that it has an integrated GPU (hence referred to as "iGPU") which can run in tandem with my current dGPU (discrete GPU, the HD 7850) by having encoding jobs such as rendering videos and transcoding sent to the iGPU in a feature called Quick Sync. In order to utilise this, I had to bind a virtual monitor to my motherboard's VGA port (as according to this post made by vaesauce on the OBS forums), and for all related applications it worked perfectly (HandBrake transcodes really quickly, and I can stream with OBS with negligible performance overhead). Except one - Premiere Elements 11.
When I booted up Premiere Elements 11 to edit a short clip yesterday, I was greeted with a screen that informed me I had incompatible drivers. I went and checked my video drivers for both of my GPUs - both up to date - reinstalled them and rebooted. Tried once again, same issue. Going on to try and edit just resulted in audio playback, and a complete failure of video playback. I found the solution was to disable my iGPU in device manager, then it works fine.
Now, here is my question - how can I have both the dGPU and iGPU enabled and still be able to edit videos with Premiere Elements 11? While it does work in this fashion, the constant going into device manager before and after editing a video is very annoying (also, I'm sure PrEl 11 could itself benefit from the QuickSync!)

Don't disable the Intel GPU. Causes more problems then it fixes. Here's your solution believe it or not. Go to download.com and find the K-Lite Codec Pack_Full and install. It seems that the new updates have been messing peoples system's ability to read Codecs. This fixed my problem and I've been searching all day every day for over a week now.

Video playback slow and audio drop out after render

Hi
I have downloaded a trial version of After Effects from the cc,
Problem is everytime I render ou,t the video playback is slow and the audio drops out
This happens with AVI or Quicktime files.
Using a Intel i5 quad core, 8 gig of ram 250 gig ssd.laptop
Render/export in Premire pro is fine.
Can any one help.
Regards Phil Green
Blue Room Media.

It sounds like you might be hitting the space bar in hopes of getting real time playback. Sorry, but AE doesn't work like that, because it does totally different things from an editing application like Premiere.
And if you've downloaded the tryout version, you really ought to learn how AE works... and a short description is "it doesn't work intuitively". You can frustrate yourself in a hurry.
But this can really help;

**Captured Video Playback Issue - Freezing

I've capture 10 short video clips, and discovered when trying to play them back on the iPhone that some simply will not play. When you open the photo app, select the clip, and press the play button, the iPhone just locks up. Totally locks up. The only way I've been able to unlock is holding down both the Sleep/Startup button and the Home button for 10 seconds and the device resets.
Once reset, if I go to a clip that works, it plays normally again, but select one of the bad clips, and it locks again (also locks if I try to delete one of the bad clips). To remove a bad clip I open the Photo app, highlight the clip or clips in question), press the options button, and then click Delete.
However, once I deleted the clips that caused the crashing, some of the clips that played normally have stopped working and now freeze the entire device.
Once while trying to delete some clips, the whole Photo app on the phone appeared to be completely empty. I restarted and it was the same - empty. Restarted again and everything was back.
Help. I've got an appointment at the Genius Bar Saturday, and am hoping we can get to the bottom of this or get the phone replaced.

Jason,
I just went through the whole restore process, and the issue persists - crashing/freezing on playback of videos captured through the iPhone, as well as fuzzy photos (both viewed through the Photo app). On the fuzzy photo side, what's odd is the first photo you look at seems to look good; all after that look fuzzy. Strange.
On the playback side, I'm wondering if there isn't an actual hardware issue that's causing that problem since the software has been completely replaced.
Not happy with the current situation at all, as the camera is a pretty central function of the phone (for my uses) and as it stands I'm better able to use even the camera from my original iPhone.
Taking this in Saturday, which is the first appointment I could get when I tried to go in on Wednesday. My concern is that tomorrow is the last day I think I could technically return this phone for a refund with no restocking fee. If I go in Saturday and get a replacement phone that's refurbished, as new as my phone is, I'm going to be feeling pretty annoyed.
Thoughts or any additional things to try?

Error Code c00d36c4: Video playback problem on Lum...

I am having a lot of a difficulty playing videos which i have recorded using the phones camera.
i can see the thumbnail for the video in the camera roll.. But they don't appear in the videos.. Under music+videos tile.
if i try to play the video by using the thumbnail..i get an error saying "Sorry, we cant play this file on your phone" followed by error code c00d36c4.
Now, I understand that this problem is due to codec and format issues.. However how is possible for have an unsupported format when the video has been **bleep** with the phones camera!!???
Any advice or solutions?

Same problem. Recording short videos on my 820 and whilst the thumbnail is showing, when I go to playback I get an error but no code. It just says ", we cant play this file on your phone". How can I fix this???

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.
