Jerky playback of footage on a Tv

I burned a movie in final cut to a dvd. However when i try to play it back on a dvd player it is very jerky, is there anything i should take into consideration?
my footage was shot on a cannon rebel t5i and a go pro hero 2 both 1080p at 24frames per second. I am aware filming at 24 frames makes the footage more jerky but what i am experiencing on the Tv screen is extreme. when i play the movie in final cut there is no problem.

i played back with the built Video-ts folder, that stored on my Hard drive.
would i still run into that problem with switching layers?
so, i guess no body ran into this problem when authoring DVD that had one 4 hour long track?

Jerky playback of XD Cam EX footage

One of our Macs is struggling to playback HD footage on the timeline and the Viewer (specifically XD Cam EX).
The footage plays fine in QT. Also it plays OK when we change the *Playback Video Quality* to MEDIUM, as you would expect I presume.
Also this problems isn't consistent, sometimes works fine when you switch the Mac on and then starts again at some point during the day.
Have tried more RAM, and the usual preference deletion.
Oddly, this is our newest Mac with, we have no problems with the other 3 older ones.

Hi John,
I think you can add yourself to [this thread|http://discussions.apple.com/thread.jspa?threadID=2628596&tstart=0] which has not been solved yet.
But since you have several mac's of which only one of them has the problem, you might be able to help finding the common denominator...

Jitter, stutter, or jerky playback on output

Hi friends,
I've edited a video in Premiere Pro CS4 and it plays smoothly in the timeline. However, when I export it for DVD output, and then preview it in Encore, every minute or so, it will play one frame out of order. I don't know whether to describe this as a jitter, a stutter, or jerky playback. The preview is accurate: if I burn a DVD from Encore, the DVD will have the same glitches in playback. Again, Premiere plays everything fine.
The frame can be pulled from before or after the current point in the timeline. The first glitch occurs at 08s 15f and plays frames in the clip in this order: 1,2,3,4,17,6,7,8,9... Then it goes to 01:24:15 and partway into another clip does this:
24s:14f
24:15
24:00
24:01
24:16
25:02
24:17 (back to normal)
Both of these clips with these symptoms have a lot of movement (people moving independently in the frame, plus camera movement), but there are other clips with nearly as much movement, and they do not have a problem.
The source footage is AVCHD 720 30p in a matching timeline. I do have some SD footage later in this timeline. This SD footage was captured to the computer via Firewire from a Canon Optura. It is "Scaled to Frame Size" and rendered in the timeline, and is causing zero problems. I exported using the Media Encoder. I am outputting to DVD using the MPEG2-DVD and NTSC Widescreen preset, with the aspect ratio changed from 16:9 to 4:3 and the quality set to 4.5.
I'm running Premiere Pro version 4.2.1 and Encore 4.0 on an Intel Core 2 Duo T9550 2.66 GHz with Windows 7 (64 bit), 4 GB RAM, a 5400 RPM 320 GB hard drive running the OS and the video files located on a USB 2.0 7200 RPM hard drive.
If any of you have ideas, I would be grateful.
Thanks,
Russ

I've been having this problem since installing Snow Leopard with QuickTime 10 way back when and it's caused me real problems with video rendering. I think it's a codec issue as my raw video files play back ok (H.264 codec), but when I export them and save as Photo jpeg or motion jpeg etc the playback has about 4 or 5 seconds of jerky playback near the beginning of the file.
I've just tried opening all my test files with QuickTime v7 and was staggered to see them all run perfectly. It is indeed very annoying.

Jerky playback of movies, Im getting desperate now, help !!

I have recently purchased a Sanyo Xacti digital camera which records onto an SD card in MPEG 4 format, the camera came supplied with Quick time to view the movies on.
I installed it and everything worked fine. I looked at the option of going PRO with the software because of the editing and file conversion facilities it offered, the £19.99 fee seemed reasonable also, so I did, during this quick time upgraded the player to the current version 7.1 also, since doing this my movies do not play back properly, the quality is grainy on some parts and the footage is choppy and laggy. I am really annoyed now as I expected to gain some useful features, not loose the one thing this player was intended for!!
I have searched through the forums for any clues and tried do some suggestions, i.e. running in safe mode, uninstalling QuickTime and reinstalling off the CD that came with my camera and I have upgraded my graphics drivers as well.
The thing is I downloaded the free VLC media player and that plays fine, the same movies also play ok on my editing software that came with the camera.
I spent half an hour on hold to apples Technical help line then got cut off! nice service eh and its cost £20 for this pleasue with no way of getting a refund or any help on the matter!! so it seems?
Thanks for any help you can give
Regards

"Copy one of your clips to your internal (system) HD. Open & play it in the QuickTime player. Does it play ok?
Do you have more than 1 project, and if so is this happening in all projects or just this one?"
Hello again ~
I have done all the memory upgrades, external (new 1TB:Mac OS Extended (Journaled) / internal: Capacity: 233 GB Available 90GB) moving new project onto 1TB drive and making more room on the internal drive too. Skipping/jerky playback still occurs.
I copied a small section, placing in & out points on a few seconds of the project. I stopped at that point because I couldn't figure how to move to the internal HD. (My brain has been on overdrive and dropping memory rapidly ~ another support topic.) Please tell me how to move the clip to the internal drive.
I did play another completed project, that had no previous problem. It did skip when the player was over the titles/transitions.
I thought of copying the project and starting w/new titles & transitions to see if there was some corruption problem, until I played the 2nd project and had the same result.

Jerky Playback and freezing

When in editing mode I am getting occasional freezing and jerky playback but the sound track continues to run. The same in full playback
The machine is a new 24" 3.06 so I doubt it is a lack of resource problem. Any advice would be appreciated.

oldmovieguy,
Hmmmm...maybe we're on to something!
I did begin another thread, to draw attention to this specific problem we've isolated. Hopefully, between the two of us, we'll figure this thing out! It is VERY annoying. Especially, since creating a movie in the new Imovie 09 is a snap. Luckily, I had marked all my good footage with a star, so I can recreate a project in a jiffy!

Jerky playback even on RAID 0

Hopefully someone has a solution to this irritation!
I am running Premiere Pro CS5 on a Dual Xeon 2.4Ghz, Windows 7 64bit with 24 GB of RAM and an Nvidia Quadro 40000. It is a new system with barely anything but CS5 installed.
I render out PSD image sequences from After Effects and when I play them back on Premiere's timeline, 720p sequences can just about play smoothly however 1080p sequences stutter consistently.
To resolve this issue I have bought an extra 2 WD Velociraptor 10000rpm drives and now have 3 of these drives striped as a single volume in a Raid 0 configuration. I've tested the Max Read of this new volume and I can get 326 MB/s out of it so no problems there.
CS5 is installed on my system C drive. The footage and Adobe cache files are stored on the RAID 0 volume and the Premiere project is saved on an external eSata drive. I have Mercury Playback GPU Acceleration selected in Premiere, I have the latest Quadro 4000 driver installed, I dragged the imported footage onto the New Item icon in Premiere so it matches the sequence settings. Reducing the playback resolution with Premiere makes no difference whatsoever.
It is so frustrating that the jerky playback is still happening. It is happening with footage shot on a Red also. The only possibilities I can possibly think of now are that there is some magic unit size I should use when creating the RAID volume, or whether AVG is somehow interfering, or if there is some feature on Windows 7 that I am not aware of that is doing things with the drives.
Does anyone have any thoughts on how to resolve this?

Don't expect image sequences to play back realtime; they won't. Actually, that's not entirely true; if your I/O subsystem can produce very high transfer rates (which it sounds like yours can, at 300MB/s) then you might be able to if your image sequences are UNcompressed TIFF. Any other compressed format (compressed/LZW TIFF, PNG, PSD) is not optimized for video playback and you're going to get stuttering. You proved this yourself by rendering to an uncompressed .AVI file which you said played back perfectly.
Your options are:
Render your sequences to uncompressed .avi
Render your sequences to a lightly-compressed format like Cineform (only slightly lossy)
Save your image stills in uncompressed TIFF
Or, you could just live with the stuttering -- remember, it's a preview issue only, your final mastered output file will be flawless. If you simply MUST have realtime playback of what you already have because you're trying to time/edit a sensitive part, adjust the work bar to cover just that section and then render the section. It will render to an intermediate format for preview which will play back realtime.
PS: Ignore this hard drive reformatting talk -- If you're seeing rates of 300MB/s out of your RAID-0 then you're hitting the maximum transfer rate of SATA 3 (which is great). The problem isn't your RAID-0.

Jerky playback in Bridge CS4

I get jerky playback of Hi Def mov files shot on my Canon 7D when playing them back through Bridge. The same movies play smoothly with no stuttering whatever on the same machine through Nero or any other player I have installed. According to my camera manual, the frame rate of these movies is 25 fps (I am in the UK using the PAL TV system) and so I set Bridge to play back at this rate (it was originally set to something like 29.77) but that made no difference. Is Bridge using a different codec or what?

Bridge uses Quicktime, so any performance issues wil lhave to be attributed to that, most likely.

Jerky playback

All of a sudden I'm getting jerky playback of video. I've tried the usual fixes: trash preferences, delete render files, repair permissions, repair disk, but nothing has helped. This happens in timeline and also with individual clips in the viewer, on all projects, playing from a variety of hard drives. It may be a coincidence, but it started happening today right after I played a few of the videos on the new google video site. Also, when I open the Mac Finder, the columns are slightly jerky, snaping back and forth laterally, which leads me to guess the problem might be in my system rather than in FCP, so a re-install of FCP might not help. My other programs are working normally. Any suggestions? I'm running the latest FCP 5.0.4.

Perhaps it is now time for the Harpoon solution (aka the Guinness solution in the mid and far west)
for those not in the know:
1. turn everything off.
2. unplug firewire cables
3. unplug power cords
4. get up from well worn chair
5. walk to refrigerator
6. open refrigerator
7. remove bottle of Harpoon (Guinness, local micro brew, etc)
8. pop cap
9. pour into glass ( you AREN'T going to drink it from a bottle, are you?)
10. sip responsibly. enjoy the moment. think pure thoughts
11. return to kitchen. If less than 15 minutes has elapsed, have another. Otherwise, retrurn to edit room.
12. Plug everything back together
12. fire up external monitors, VTR, external hard drives & computer in that order.
does it work now? If yes, congratulate your self. If not, oh well, but at least you are in a much better frame of mind to begin some serious troubleshooting.
cheerios,

Does adding RAM help solve iMovie4 jerky playback

I have been reading threads about jerky playback in iMovie4 in large projects, after adding music from iTunes etc. My wife has a monster project and playback during editing has became very eratic. I have emptied cache, repaired the hard drive, repaired permissions etc. I have not tossed iMovie preferences. I have 23 gigs of space on the HD and a 250gig external FW HD that I bought after she started the project on the internal HD. I would like to know from you experts: 1. Would it help to move the project to the larger external HD? 2. Would adding RAM help (currently iMac G5 1.8mhz with 768 megs RAM)? 3. Is there any way to tell if the project will export to iDVD smoothly if it continues to look terrible in iMovie playback? I hate to go through a few hours of rendering for nothing. Thanks so much for your help. I always find good and useful info in discussions.

Michael, there are some very useful applications that I highly recommend to keep your Mac running smoothly. As a defragmenter I use Allsoft's Disk Warrior that also has a very good directory repair feature. Check out also Drive Genius that has a host of useful features. Also get iMovie file fixers, invaluable tool that is free that will allow iMovie to import certain files in audio and photo formats that are greyed out and also has other features. I believe I got mine from Mr. Lennart Thelander in previous posts here. Cache Out is an excellent application to clear out cache files. I also advise you do a regular permission repair from Disk Utility in your Utilities folder that is on your Mac. These are basically my must have applications. As for copying your iMovie project to your external, just drag your entire project folder ( the blue one with the media and star folder(s) in it directly in the external hard drive. I find that iMovie is one application that requires a clean (defragmented) drive with ample space to spare. I defrag my drives if I trash files often from them, or if I notice erratic and jerky performance or slowness in response. I hope that some of my suggestions will help your in your editing.

HELP! Jerky playback on Premiere Pro 6.0.2 CS6 and Retina MBP (16GB)

Dear all!
Please help me to solve this problem!
It's going on Premiere Pro 6.0.2 CS6 and Retina MBP with 16GB RAM installed.
CUDA Driver Version: 5.0.24
MacBook Pro Retina, Mid 2012
Processor 2,7 GHz Intel Core i7
Memory 16 GB 1600 MHz DDR3
Graphics NVIDIA GeForce GT 650M 1024 MB
Software OS X 10.8.1 (12B19)
Adobe Premiere Pro CS6 (6.0.2. - 072)
While playing back inside PP a jerky playback occurs, every 1-2 seconds it rewinds to 2-3 frames back and continues to play forth...
No special console messages or something similar visible.
Have tried to clean the cache but it doesn't help. Also have tried to switch the mode between CUDA, OpenCL and SW - without any visible changes...
Exhausted... Please HELP!!!!

avrbox, I had the same problem and went crazy because I didn't find a proper solution. I use Windows, though. Finally, I got to fix the problem. I use a i5 processor, which I overclocked with an asrock tool that came with the mainboard (to about 3350 MHZ where the system ran stable). When I turned overclocking off, Premiere played back the clips just fine. I overclocked then step by step until the playback went jerky again and kept that frequency. Maybe your processor is overclocked by stock or you did it manually?
Hope this is your solution!

Jerky playback - even after render

Hi There
I recently animated a clip based on the 20th Century Fox intro, and then imported the clips into Final Cut Express to touch it up and render it out. When viewing it in FCE it appeared to skip a frame or so every 50 frames. I figured this was just something happening within the application, and that when I exported it to a QuickTime Movie, it still did the same thing.
Any ideas on why this might be happening, and how to solve it? The problem is definitely arising from FCE, not the animation software. If it would help, here's the clip here that was exported from FCE. http://dominomf.com/smcfiles/Cuby__20th%20Century%20Sheep44.mov (.mov 2.1 MB)
Cheers
Cuby

Thanks for the comment. The reason I've used a frame rate of 26fps is because the DVD I used to watch the original 20th Century Fox clip had a frame rate of 26fps, and doing the same thing in 'Blender' allowed me to get my parody as close as possible to the original, as far as timing goes.
Do you think if I re-rendered the clip from Blender as a DV-PAL format, this would make any difference?
The clip linked to in my first post was going to be the finished product, so that is why I would like to get rid of this jerky playback.
Thanks again
Cuby

Jerky playback in elements organizer

Hoping some one can help out here. I've downloaded the trial version of Premiere elements to edit videos captured with a Kodak playsport. When I view the captured video in the organizer, it a very jerky playback. When I play back using Windows media player or quicktime, it's nice and smooth.
I've tried capturing the MOV files in 720p and 720p (60fps) and have the same issue.
Anyone have any suggestions?

Jerky playback in PE is almost always because you have not rendered the area where the jerk is. - or else you dont have a fast enough computer or enough RAM or have everything on one computer hard disk.
If you have a horizontal red line above any of your video in the time ine it means you dont have it rendered. It is caused every time you insert a transition or effect or if your original meaterial doesnt match the original project settings when you imported the video.
You dont have to render the whole project if there are only parts with a red line - just adjust the work space pointers to cover the red line and render that.
There are numerous posts in this forum about it and the way to cure it

Jerky playback of movies only in iTunes

Have movies that play perfectly directly from Quicktime (7.1.3) and when loaded on the iPod with iTunes. But when the same file is played within iTunes (7.02) as a movie, the playback is jerky and like stop motion. The apparent frame rate is several per second. Audio playback is fine whike this happens.
Activity Monitor shows about the same level of CPU utilization in both applications Quicktime and iTunes, at around 20% on my 1.6GHz G5 Powermac.
I have Quicktime Pro if it makes a difference.
Using EyeTV (2.3.2) and playing back as a Qucktime movie also produces a clean playback.
So, the jerky playback is only in iTunes.
OS X version is 10.4.7, I'd rather not update to 10.4.8.
I've looked for preference settings and other interactions. Any suggestions?

If you search (itunes forums) you'd have found this tidbit:
I found the problem! The jerky playback in iTunes7 is caused by a conflict with the 3ivx D4 4.5.1 component found in the Library/Quicktime/ folder.
It may also be say an old DivX codec, etc. Same folder. Remove to your desktop and try again.
Also some have reported turning off the internal mic if you have one, and making sure MIDI settings are at 44.100Khz.
Give these a try.

Jerky Playback of iTunes purchased TV Shows (specifically: HEROES)

Not yet another jerky/playback thread?
Well, I feel compelled to do so since I have reviewed all of the jerky/playback threads that I could find and I have tried most, if not all, of the suggestions. Namely:
1. This thread: http://docs.info.apple.com/article.html?artnum=303706
2. Uninstalled Quicktime and reinstalled (ver. 7.1.6)
3. Setting "waveout" for audio.
4. Tried several bit settings for audio (16, 24) along with sampling rates (44000, 48000).
5. Tried two different versions of NVidia Forceware (ver 97.46, ver 158.18)
6. Two different sets of drivers for SATA
The thing that gets me is, I've been watching HEROES all season without incident. In fact, I preferred purchasing each episode and watching it in iTunes as opposed to watching the episodes in my BeyondTV DVR (computer based). One has to conclude that SOMETHING on the system has shifted to affect this change (within the last week), although I'm out of ideas beyond the 6 listed above. I'm tempted to boot into my XP partition to see if everything is fine over there but that would mean I would have to go through the as-of-yet-unfamiliar-to-me process of deauthorizing this "computer" and hoping that my purchases shows re-download. I did this once and I lost the first 6 episodes of Heroes and even "redownloading purchased" media did not bring them back. That's a separate issue that I need to contact Apple about.
So...any ideas? Any information that I'm lacking here to help troubleshoot?

Update:
I booted over into Windows XP (SP2) and everything is fine over there. So, that leads me to the strong inclination that there is something up with the configuration on this side of the divide (Windows Vista 32-bit).
I'm now beginning to suspect some recent tweaks that were made via the nTune application. For those that don't know, nTune is a utility that allows tweaking of nVidia hardware (nForce, n4 - mobo, PCI bus, SATA, video, etc.) What I'm currently trying to research is getting the automatic tweaks that I enabled to rollback to their default settings. So far, I haven't figured out how to do this. There is an option to load a "baseline" profile from within nTune's menu however the behaviors that I noticed post-tweak are still there (difficult to explain but there are indicators that the new settings are still in effect).
I'll post back here if I am successful in rolling back the nTune tweaks and see if that makes any difference with the video playback problems I am experiencing.

Jerky playback of wmv files

Please can anyone suggest how to fix this. Medium size wmv file (128Mb). Flip4mac version 2.2.3.7 and QuickTime 7.6 (472). Very jerky playback of both audio and video with much spinning beachball.
Message was edited by: Roger Sinden

Medium size means nothing. How long is it? If it is one minute that is a really high bitrate video and the G4 may not be able to decode it fast enough.
Try this - open it, then "save As" which will save it into a MOV container (it will still be WMV video).
See if it plays back nicely. Also try a computer from more recent times.
You can see a 128 MB WMV will save as a 256MB or even bigger MOV file as the video is not compressed any more in the MOV container.
