Jumpy playback on Vista

A week or two ago, I got home from work, opened up iTunes to listen to some music, and the blayback is INCREDIBLY jumpy. It's to the point where it's unlistenable.
I called Apple Support, who weren't the greatest deal of help, and they told me to uninstall iTunes, Bonjour and Apple Mobile Device Service or whatever, then reinstall the package of all 3.
Well, I did that before they even told me that, and they insisted I try again... So I did, and it's still knackered... Any suggestions? It's an absolute pain!!!

Jumpy playback in vista x64

i just built a new computer, and it's having problems playing back .mov files smoothly. the same .mov file plays back just fine in vlc. however, i need the scrolling quicktime offers.
so far i've tried:
-latest quicktime version
-disabling directX and all related options
-running in safe mode
-updated video card drivers
-tried a few old quicktime versions.
computer specs:
intel i7
12 gigs memory
quadro fx 3500
thanks!

the file was a game cinematic. a coworker downloaded it, so i cant provide the link right now. but it was the quicktime trailer for star wars: the old republic. quicktime lists the codec as h264, and vlc lists it as avc1.

Jumpy playback?

I was wondering... Has anyone else been experiencing problems with playback in iTunes? I have a ton of mp4 videos that I try to play using the video player in iTunes, and it's pretty painful to try and watch... It pauses every second or so, and skips sections of video as it tries to catch up. It's somewhat better playing them in Quicktime. Song playback in iTunes has been kind of jumpy as well. The mpeg files I have for the movies play great in Windows Media Player though. My computer runs extremely well in every other application, so I was wondering if there was a known bug for iTunes playback in Vista or if there was some setting I was overlooking.

I can't help myself, but have you worked through the article on video playback performance?

Dropped frames - jumpy playback

I just moved an old FCP3 project to an external drive and opened the project in FCP5. I'm getting dropped frames and generally jumpy playback in the canvas. This may have nothing to do with FCP3 > FCP5 conversion- just thought I'd mention it. Perhaps just a simple oversight in one of my settings. Any ideas would be extremely helpful.

#12 Dropped frames on capture/playback
Shane's Stock Answer #12:
http://docs.info.apple.com/article.html?artnum=58640
1) Do not capture to your main system drive. Since it is busy reading the operating system and application files, it will intermittently drop frames during capture.
2) Do not under any circumstances run any anti-virus/filesaver software. Including Norton and Virex. Sure, Apple doles out Virex for free, but FCP doesn't cooperate with it very well.
If you absolutely feel you must keep Virex installed on your system then use Kevin's script to shut it off before you use FCP:

3) Check the format of the drive you are capturing to. It should be Mas OS Extended, jornalling off. If it isn't, copy your files from it and re-initialize it. If it is any other format, you will encounter problems. If not at first, then eventually.
4) Trash the FCP preference files. Use FCP Rescue available here:

Jumpy playback on laptops

I've been having trouble with jumpy playback on different laptops. I tried lowering the bit rate but it didn't help.
I'm transfering an hour and a half DV footage to DVD.

Welcome to the boards
Which laptops and which version of DVD SP and which computer do you have?
What bit rates did you use, did you encode outside of DVD SP?
dvdstepbystep.com/faqs_3.php
dvdstepbystep.com/faqs_7.php
Also check your brand of media.
Some software players behave inconsistently, in fact I have now found some combinations of DVD SP and Apple DVD Player which will stutter. skip and stall when playing back from the Hard Drives depending on which version of DVD SP I have used and other issues.
But in general
1.) Lower bit rates
2.) AC3 the audio
3.) Good brands of media
would be three of the first things to look at (also DVD drives can get dirty go bad.)
Do the DVDs play properly on standalone real DVD Players?

Jumpy playback with subtitles ?!

Hi There,
I'm experiencing jittery / jumpy playback of my track with subtitles. My project has a coupe of tracks but only one has subtitles. I burned a test disk and found that on my Powerbook and DVD&TV set, they all play fine, but on a PC the subtitled track plays jittery (the others are fine).
In DVDSP simulation mode I get the same result. It's almost as if the track hesitates then jumps just before a new subtitle... especially if there is a lot of movement in the image. Playing the track from the DVDSP timeline does the same thing, but not as bad.
Any suggestions or solutions? Please?
Peter

hi peter
the problem of jittering happens most of times when we dont give
any stroke or outline to the texts.
so try these values for your subtitles
text colour white- opacity 15
outline 1-black-opacity 15
outline 2-black-opacity 15
try also with bold fonts and with bigger size .

Jumpy playback in iMovie since i started importing HD videos from my 4s iphone

I am getting poor jumpy playback with my 4s iphone vides in iMovie. Is this because I have too many projests going or too many clips? I have a macbook pro with 4 gigs ram and 95 gigs left on my HD.

What might be happening is you might need to Optimize the Video to Full Size. Use the File Menu > Optimize > Full Size for each of the video clips in your iPhoto Videos folder inside of the iMovie Events Library. That should trigger iMovie to recognize the original size/resolution of the video clips and then enable the HD size output in the iMovie Share Menu.

Jumpy playback from image sequences rendered in Apple Prores and then exported to h264

I will start by saying I have been using FCP since 1.0 and am in no way new to this software, but this issue has me going crazy.
First the Specs:
MacPro 2 x 2.66 Quad cor Intel Xeon
16 gig Ram
OS 10.9.2
FCP 7.0.3 (sorry but I am not a fan of FCP10 at all)
In other words, a beast of a system that has played back everything I have ever built on it for years until now. So now for the issue: I work with an amazing 3D Max builder and we have created a building animation exported from that program into and image sequence ( we have tried JPG, TGA and PNG still all with the same effect). I open Quicktime 7 Pro, build the image sequence, save as .mov, import into FCP and drop it into my 1080p30 Apple Prores (HQ ... we also tried SQ) timelines. The timeline renders perfectly and I can play the video perfectly through my system out of Firewire 800 to my Motu V4HD device which then converts the signal to HDMI to my 55" LED TV. The video and playback is perfect.... until:
If I try to play back the same exact time line into an exported video file, the file will play back with random jumpyness in it. I say random since you can play it back 10 times and it will hiccup during playback at different spots in the video. If you review every frame in the file though using Quicktime 10, 7 or VLC viewer, every frame is perfect. So, it must be the data rate right? Wrong. I have exported now to H264 MP4, M4V, MOV , ect, etc at different data rates from 4mb to 40 mb per second. They all have the same randow jumpyness to it. So it must be my computer right? Nope. I have a Macbook pro that is more powerful than this machine and I rebuild the file using the same method (something I have done a thousand times before) and the exported file does the same thing on that machine. I had my friend do it on his machine... same thing. ERRRR....
We have even tried using After Effects and Premier to the same result. Rendered it straight from Quicktime Pro, same. Rendered it to 720p30, same. Render it to 24fps, same. I had another editor render it using whatever methods he wanted to use... same. Tried Compressor, SAME. Tried Adobe Media Encoder, SAME......We even, god forbid, used a PC running Premier and built the image sequence and rendered to h264 at 30fps, 5mbs.... @#$@#$ SAME!
We just remade the 3D Studio Max export into a 60fps animation since I thought that the individual frames we appearing too far apart and thus causing the jumpyness. That was causing the playback of the upclose objects flying across the screen fast to appear jittery, but not the random playback jumps. The 60fps did smooth out the animation greatly during fast flybys, but the playback jumps are still there in all players, QT, VLC, the web, etc.
I was starting to think this issue is realted to Mavericks, but since the PC did the same thing that is not it either. I have linked a sample of the clip below exported to 720p30, 25mbs... something that is much smaller than the original and should playback smooth very easily on any of my systems.
FYI: I have now opened numerous projects I have edited over the last few years and noticed that all of them are now jumpy, so this isn't just an image sequence issue. While the other projects don't use image sequences and instead are shot footage edited together, there is still the random jump (far less than the image sequence as you will see) but they are now there... ***? I have cleared preferences in FCP which helps for a short period of time, but once exported I get the same glitch.
As I said... I am stumped... ANYONE have ideas for me to try?
Here is a sample file for you all to see and please tell me if anyone does not see the issue after playing it several times in a row.
www.media3lv.com/switch/NORTH-sample-720p30_25mb-sec.zip
One last thing to note... my main goal for these videos is YouTube or Vimeo playback via our company website. I have a few other animations online right now using YouTube and the problem is also showing there. At first I thought it was just my videos, but I have looked at numerous YouTube videos now showing 3D animation and alot of them are jumpy.
www.supernap.com/supernap-building-design.html
www.supernap.com/supernap-tscif-exchange.html
These don't show the issue as bad since the camera fly is much slower, but why is this occuring and is it coming from my source, or is this a known youtube issue? I can program this using out own modules, but YouTube and Vimeo allow for multiple resolutions and a checker script which makes it easier to share over all devices at all quality up to 1080p.
Advice is welcome and appreciated?

I have tried at actual, full screen, using 1080p30 size from the original compressed to 4mbs (something my system can handle without blinking), 720p30, etc. etc. etc. Nothing stops the jumps. Even the activity monitor shows only 5%-15% processing being used by QT and/or FCP.
I plan to pull my old G5 out of the closet, it runs 10.6.8 and is still rock solid for video editing in FCP7. If it plays smooth on that 8 year old system then I know it's Mavericks. I'll try that tonight. It floors me though why the original 1080p30 will playback perfect via FCP and Motu, but once I turn of external monitoring and just try to play it via the preview monitor it is jumpy as **** and then the exported file does the same thing. So strange. I even deleted prefences of FCP and that does help with screen playback initially, but it always gets jumps in it after playing for a while.
I knew I should not have started using Mavericks and I HATE FCP10.

Jumpy playback on 30" display

Following the release of CS3, I upgraded my G5 to a Mac Pro, with two xNVIDIA GeForce 7300 GT 256MB graphics cards. Along with my 23" cinemay display, I connected a new 30" Apple HD display. It is a beautiful thing, until I try to play movies or shows purchased from (and played on) iTunes. Playback is jumpy -- completely robotic, as if it is constantly stopping, then skipping a frame. This only happens during full-screen playback in iTunes.
Full-screen movies playing from the DVD Player or VLC are fine.
Any help will be much appreciated -- thanks --

Hi-
Appears to be a problem in the iTunes software. I don't know if it would help, and there aren't any reports of anyone trying it, but sometimes software reinstall fixes system bugs ( if the problem is in ones system).
Did a search, and found that you aren't alone (kinda' counters the "system problem" theory).
You might have a look and see if any of the "fixes", a few have reported, apply to you:

Jumpy playback in CS3

Was a fix ever found for this? I did a search and found a mountain of posts all over, but no solution.
Everything worked fine here until I upgraded my video card to a GeForce 7600 GS now the playback window is jerky.
Tried re-installing, changing the pagefile to none, then to one, then back to two as Microsoft recommends. The computer partition it's on is only used for video editing, only loaded with Adobe software (plus stuff like Nero) and isn't connected to the net.
AE CS4 runs fine, and I've just re-installed Premiere Pro 2 which runs fine, but Premiere CS3 is still jumpy...

Why would you assume I have only one hard drive?
On the machine I have in question I have 5 internal hard drives, two in RAID 0, with several tetrabytes of memory. Drive 0 has 3 boot partitions: music / video / intenet & everything else. All data is spread across the other drives, like sound on Drive 1, video on Drive 2, video render files Drive 3, etc.
I've been using Premiere for over 10 years. Not exactly a noob. Everything works fine here, and has been on this machine for 2 years, except for Premiere CS3...
I take it your response means you never got to the bottom of the problem of the CS3 memory leak..?

Playback on Vista

I've authored a DVD via FCP - Compressor - DVD St Pro - all latest versions. It works fine on mac, Win XP PCs, and on set-top DVD players, but my client tells me it won't play on their Vista build. Surely this is to do with Vista, not anything to do with the build. Has anyone experiences probs like this?
Any advice gratefully received!

Welcome to the Boards
If the DVD is running on Win XPs, Macs and set top players, the chances are that the build is probably good. So it could be related to Vista or how they are trying to play it back. Have they tried opening the DVD in whatever player they are using? Also there is a chance that it is a bad burn, but if the other machines are playing them...usually if there is a bad burn one or two playback mechanisms may compensate, but not all of them.
Have they tried another DVD Playback software? Any error messages report? How did you burn the DVD?

Jumpy playback with full res HD

I am trying to edit full res HD(1920x1080, 4:2:2). When i am playing the clip in the viewer or the timeline it is real jumpy. Is this a hard drive performance issue? or is it something other then that.

How much faster do you thng 2 750gigs in a raid 0 setup be?
Depends on the Raid controller and the type of drives you have. I have a CalDigit S2VR Duo and can get 148MB/s Raid 0 empty, and 102MB/s 90% full. That is eSATA, and that is not recommended for uncompressed HD. DVCPRO HD, HDV, uncompressed SD, yes. You can purchase eSATA enclosures from OWC or Sonnet and get about that....85-105MB/s. But that doesn't give you a lot of wiggle room. Uncompressed HD requires a 4 drive SATA Raid or better for smooth playback.

Having jumpy playback with 60p footage exported to 30p. Pans are worst.

We recently shot a commercial on the Sony FS700 in the native AVCHD codec at 60p. We originally intended to slow the footage down to 30 but the client decided the natural speed worked better. So we simply cut the spot in a 30p sequence and exported. The playback is VERY jittery/jumpy with any vertical lines in the picture, which is very pronounced in any pans. We then cut it in a 60p timeline and exported 60p then converted to 30p, same issue. I did have frame blend on every export.
Exporting 60i does help tremendously, some stations won't accept the 60i file however which sticks us with 30p files which have the issue. The XDCAM 1080 60i file is perfect, however ProRes 30p is not.
Any ideas on this?

Believe it or not, the Import method can sometimes affect playback. Be sure to copy the entire AVCHD folder structure over from SD card to hard drive, unmodified, then in Premiere use the "Media Browser" to import your clips for best results. A definite plus for any spanned clips for sure, also helps with some audio issues.
Also, my understanding of the Interpret Footage option was that if you put 60p footage into a 30p sequence, and also used "Interpret As 29.97" then the footage ought to be playing back at 50% slow motion speed. Something seems off here.
EDIT: Or maybe that's what you meant, the slowmo is perfect?

Jumpy playback from my apple tv

I have had my apple tv for about a month, can watch movies downloaded from i tunes with no bother. Downloaded a tv show and now watched it through the apple tv and it was really jumpy and jittery playback. i then checked another tv show and that was the same, however tried a movie and playback was perfect. can someone help me as i'm at a loss. I was streaming it from my macbook pro.... any help would be excellent

it sounds like an issue with your network.Also is b/g/ or N standard router.
Try restarting your router and ATV2.
Are you doing anything else on the network while your watching the downloads

Playhead moves jumpy in win7/vista (even in empty comp)

hello,
after switching from winXP 32bit to win7 32/64 (and vista), im having this problem with both AE cs4 and cs5:
when i start playback or do a ram preview even in an empty comp, the playhead/cti/current time indicator red line is moving in a jerky way. The Info
panel is showing that its being played in realtime and when i add footage, the video is being played smoothly as well, yet the playhead jumps.
heres a screencap of it: http://webstuff.ic.cz/jerkyPlayhead.wmv
What i tried:
- AE cs5 in win7 ult 64bit
- AE cs4 32bit in win7 ult 64bit
- AE cs4 32bit in win7 ult 32bit
- AE cs5 in vista basic 64bit on different pc (laptop with completely different hw and drivers)
- AE cs4 32bit in vista ult 32bit on different pc
- those OS instalations were clean literally with just AE installed, i then tried installing drivers, qt, windows updates but still the same
- tried changing all AE settings i could find, as well as leaving default settings after clean install
- watched everest stats during the simple comp playback, plenty of free cpu/mem resources
my hw: [email protected], p5e64ws evo, 4gig, hd4870 512
Having tried on different pc, it should not be hardware/driver related, also not OS related within vista/win7 versions and not AE version related. So the problem should be between xp and w7/vista, something is different or missing between those.
This is my first time using OS newer than XP so maybe im either missing something which i didnt need to install on xp and should have now or is this the way how ae is supposed to behave on vista/win7? Does the playhead move supersmooth for you pixel by pixel when the visual playback is realtime/cached in w7/vista?
Any help or tips appreciated

Yes everything else works fine. Im doing alot of intensive audio syncing and altho i make great use of all the various other tools for that during the finalization stages, the ability to simply watch the cti during previews definitely helps me to get general feel and ideas for positioning and rough ins without spamming markers or deciphering scrub sounds too early, i can also quickly position main keyframes during just audio previews without waiting for full video preview in heavier comps. Its small things that add up and it generally speeds my current routine up in various situations. Iam doing alot of precise sync editing in NLEs too, and its even more about the cti there so i guess i might be just too used to it and now it feels wrong when it suddenly doesnt move smooth in AE after i switched os.
I would at least like to know whether its "officially" supposed to move smooth in vista/win7 just so i dont spend all this time investigating the problem only to find out that its actually jumping like this for everyone and they just dont care. Because ive tried close to everything by now and still cant find the cause.
