Jerky playback of video project

When I play the project, it is very jerky. I thought there might be too much going on w/ transitions, motion in the title, edge feather, altogether slowing things down. Then I thought maybe my hard drive was getting close to full and causing the choppiness. I moved 10GB and now have 70GB left on the 500GB Lacie external hard drive.
Do I need more room on the hard drive?
I added my Lacie drive to Spotlight privacy list.
I'm not using TimeMachine.
No other devices connected.
Thanks,

"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 of video clips in iMovie

Just purchased a Sony Handycam (DCR-SR37E), and the movie playback is very jerky: the red line doesn't flow smoothly through the clips and the playback correspondingly jumps about. The sound is unaffected - it plays back smoothly.
Is this a problem with the computer being too old and slow (iMac G5) or is it a Sony vs Mac issue?

Wow- what a pain!! Just got the brand new MacBook ($999 version) for Christmas, and edited movie in iMovie 09....When I play it certain clips are extremely jerky on playback when I try to convert to youtube or quicktime...Latest Leopard OS- Flip Camcorder...So, basically, the Christmas video is ruined- even though the actual clips are fine...And its strange, because on playback different clips are jerky at different times...Anyone????

Whenever I press spacebar to playback my video project in final cut pro X, the color wheel pops up and freezes the computer. Doesn't matter what computer I use. Why and how do I fix this?

Like I said, I'm doing a simple video and have finally made some progress in editing. All of a sudden, when I try to replay the video the color wheel pops up and nothing works. It just keeps spinning and spinning with no end. I end up having to force quit the program. When I restart it the same thing happens. I've tried it on 3 different computers and the results have been the same. I've read that perhaps the software needs to be updated through the mac store, I did that to no avail. I also read that perhaps the preferences for the project/final cut pro need to be reset. I downloaded a program that is supposed to do this for me but it didn't work I also went into Preferences in Final Cut and hit reset under editing tab which also did not work. I"m really frustrated about this and I"m getting paid for this video. This needs to be resolved ASAP. Thanks in advance for the help: ask any questions.

Please give complete details of your system and the media and the project properties.

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,

No Playback on videos in the Project (PE9)

Hello
I need some help with a serious problem. I have been having some problems with Adobe Premiere Elements 9 for a while. Whenever I go to playback a video in the project the video won't play, but the audio will. This goes for what is in the timeline and the actual videos (not in the timeline) when trying to replay them in the program. Also whenever I move the marker (the thing that represents where you are in a video) if the video changes it is extremley choppy. Please help. I am running a Compaq Presario CQ56 Notebook PC with an Intel(P) Celeron(R) CPU 900 @ 2.20 GHz. I have 2.00 GB of Installed memory (RAM). I am running Windows 7 Home Premium. My system type is 64-bit. Please help.

1st, you need lots more memory... 2Gig is BARELY enough to load Win7 64bit... with nothing left over for programs
2nd, a notebook will usually have only one 5400rpm hard drive... you need a 2nd 7200rpm hard drive for all of your video files (see below)
3rd, depending on the type of file you are trying to edit, you may simply not be able to edit at all with a Celeron
4th, what is the type of video graphics adapter, and what is the driver version?

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 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 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 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.

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.

How to create a DVD with multiple video projects

I want to burn a DVD with several short video projects so that it will run without stopping in between.

Hi
*Play all resp one chapter at a time*
Play All Button
1. There are NO - Play All - button in any version of iDVD
2. It can be faked in several ways
• Easies and most fault proof way is to make a doublet movie containing All and with
Chapters set to match. It will take up x2 space but is easy to understand and produce.
• It's said that one can put all movies into a Photo/SlideShow and this will also
give the function of a Play All button - Never tested though.
• Using another program to do this eg. Roxio Toast™ where there ia a Play All button option.
Mike Evangelist1
You might be able to get close to what you want by using a slideshow in iDVD. (It's not widely known, but you can put videos in a slideshow.) If you set the slide duration to manual, playback will pause after each movie/slide, and you can continue with the 'next' button.

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.

Same thing for a movie file.. If you want to play back the movie via a DVD and a DVD player you must create a Movie DVD and not just burn files to a data DVD... as Data DVDs are just storage devices for files and therefore will only work with computers...
Movie DVDs are special formats that include things like menus and special file formats.. so they can playback via a DVD Player...
You will need a 3rd party DVD Burning app like Toast which is what i actually use.... or the more popular DVD Creator app...to create and then burn a Movie DVD that will playback on a DVD Player....

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.
