DVD+R DL Intermittent Jerky Playback

Using Verbatim DVD+R DL Media
I exported from DVDSP to .img and burned it to disk in disk utility. Seems to mount fine on my macbookpro computers... but the playback in the DVDplayer application is intermittently jerky. When I hit the stop button and play again... it goes away and everything plays normal again without the jerkiness.
This disk is not recognized by my older Powerbook G4 with DVD drive.
I will be sending this DVD in for Replication...
Since all the data was verified on the disk and it appears to be playing perfectly fine on one computer... should I be concerned if it doesn't on another? or be concerned about it not mounting on a Powerbook G4 with a Combo CD-write DVD-read drive? Would replication fix these problems?
See additional information on this problem at the thread:
http://discussions.apple.com/thread.jspa?threadID=1588705&tstart=0

Could be an issue with the media, the playback device or your bitrates. Hard to say from here. What was your bitrate and did you use AC3 audio or PCM?
Also supplying a DL disc for replication is a big error. Output 2 DDP images and deliver that data to the replicator (layer 0 & layer 1) on HDD or DLT tape. Depending on who your replicator is, its possible you will be replicating thousands of DVD-Rs and will show in some players as the DVD-R format not DVD-Video. Then there's possible read error that can occur. Also depending how your title is authored, You cannot be assured your layer break will be set as intended.
Replicators don't know DVD - they just sell plastic. Give them something to work with. DVDSP allows you to output DDP images used by replicators - thats what this option was put there for - use it! Your a professional, so give them a professional submission and you should expect professional results.

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 - 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 & asset replacement issue

Hi,
Just downloaded the trial version in order to see if it corrects some things I needed on 1.5
So appart from the better responce and added features wich are great I have 2 problems (so far!).
Problem No1 is that the playback of the mpeg (*.m2v) file on the timeline and DVD Preview is very jerky and unstable. I used the same assets in 1.5 and playback is fine there.
Problem No2 and major for me is that when I replace assets in a previously created project the asset length doesn't adjust automaticaly. That is not a problem if the asset beeing replaced was longer since I can drag the end of the replacement asset on the timeline, and it snaps to the right length. But when the asset beeing replaced is shorter than the new asset there is no way I can drag the end of it to he new duration. Only way is to delete the m2v from the timeline and re-enter it, but that deletes all chapters and links to allready created menus with it. Is there anything I can do about that? I use asset replacement every day and this is a major drawback for me. I will have to stick to 1.5 for the time beeing...
Anyhow thanks for a great piece of software wich I was much expecting and sure to buy soon.
Cheers
Christos

Christos.
For the asset replacement options that are not working as you expect, try this:
PROBLEM:
When replacing an asset in a timeline that is longer than the original, it is not always possible to extend the duration of the new clip by dragging it.
METHOD:
1. Create a new project.
2. Import an .m2v file and it's corresponding .wav file.
3. Make a timeline with these assets.
4. Click the .m2v or .wav asset in the project window, press Ctrl-H, and replace it with an .m2v file that is LONGER than the original. After importing notice in the timeline that the new length is the same as the old one.
5. Drag the tail of the replaced clip to extend its duration.
RESULT:
When you drag the tail of the .m2v or .wav file to extend the duration, the clip 'flickers." If you release the mouse when the clip "flickers" off or when the mouse is beyond the maximum duration of the clip, it reverts to the original duration. The same behaviour is exhibited when trimming the clip.
Note: Although .avi files exhibit similar flickering, you can extend or trim the clips without issue.
EXPECTED:
The duration of the clip should always be extended or trimmed to the point where the mouse is when the button is released. If the mouse is beyond the maximum duration of the clip, the duration should be extended to its maximum (like PPro).
WORKAROUND:
1. Position the CTI at the desired out point.
2. Drag the tail of the .m2v or .wav file as close to the CTI as possible while it still "flickers" on.
3. Zoom in on the tail of the clip and repeat step 2 until the clip reaches the desired duration.

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.
Mike Ryan

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 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.

CPU spikes & jerky playback of audio or video content

I've been having a problem with the flash plugin this year. I'm not sure when it started exactly, but I'm certain that this wasn't happening during 2011.
When at a site that uses Flash for video+audio (Youtube and similar) or even audio-only playback (Turntable, Pandora, etc), I find that the flash plugin causes spikes of 100% CPU usage (on one core) and that the video or audio will pause for a moment during those spikes. The disruption is typically in the 100-500ms range.
Frequency of the spikes seems to vary over time. It's fairly typical to experience a situation where it starts off bad and the frequency of disruption lessens over the course of 30 minutes until there are no disruptions at all. If you keep using playback, it'll work its way into being bad again. You're likely to start using the flash plugin at any point on that sine wave of disruption intensity. It might start working well but slowly get worse, it might start bad and slowly get better, it might start at a tolerable level and work its way worse or better depending on if you're on the rising or falling side of the cycle.
Whatever it is, it isn't my Windows install. I switched from an AMD FX-8120 to an Intel 3930K about a month ago and this problem persisted through new hardware and a fresh install of Windows using the latest device drivers for everything. I've even tested different browsers in case it was an issue with only the non-IE plugin or with my specific browser (Opera). The issue happens in Chrome, IE9, Opera, and FF on my system. I've also tested both with and without hardware acceleration, but there is no difference.
I have to wonder if there are any known issues with particular sound cards (Xonar STX), unusual video configurations (dual Radeon 6970s in crossfire), or peripherals. Perhaps with output sampling rates (96 KHz) or security software like MSE?
Anyhow, I mention this here in the hope of either raising awareness of a problem or finding answers if this is a known issue. It's silly that playing back audio would be a challenge in 2012 with good equipment. There is sure to be a logical explanation that can help lead me to a resolution. Thank you.

Hey Tbird, I was asking the guys about this jerky playback bug here:
https://bugbase.adobe.com/index.cfm?event=bug&id=3155813
It turns out this problem is very likely found in mainly computers with single-core CPUs or low-power mutiple-core CPUs. What type of CPU model is on your computer?
My advice to everyone who has this jerky or choppy or stuttering playback on Flash Player 11.2 is to downgrade back to Flash Player 11.1 for now until the Adobe guys can fix this problem which seems to be with the multi-threaded decoding engine introduced in Flash Player 11.1. Make sure you uninstall Flash Player 11.2 completely before installing Flash Player 11.1.
You can get Flash Player 11.1 in this zip file archive from the link below. Just make sure you look for the right setup folder with the right setup program file in zip file archive (For example, if you got Windows 64-bit OS, then look for win64 (or x64 for windows ). If you got windows 32-bit OS, then look for win32 (or x86 for windows)

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.
