Video Stutters

I have a Quicktime movie in my Keynote presentation. When I play the presentation, the video stutters. When I play the same movie outside of Keynote all is fine. Would anyone have any suggestions? Currently running on 2.33 GHz Core 2 Duo MacBook Pro with 2 GB RAM.

I believe I found the problem: very long audio files from books on cds
I restored ipod again, and only put one music video on the ipod. The playback was great. So I made sure not to add those long audio files and playback is good as well, no more skipping in middle of tracks.
Hopefully, this will help someone if they encounter a similar situation.

I made a duplicate copy of an imovie HD project and when I updated the titles on the copy, the video stuttered . I'm using Snow Leopard OSX. The length of the movie increased unexpedtedly too.

I made a duplicate of an imovie HD project so I could have two different versions. I tried making the copies both by using File> Duplicate and the Save As command in imovie.
When I changed the title on the copy, the video stuttered when I played it back. Also the overall length of the movie increased by about 6 seconds throwing off some sync even though the replacement title was exactly the same length in seconds and frames as the one I replaced.
any thoughts how to fix this?
I'm using OSX 10.6.8.
thanks.

*24 December 2009*
*Dear Mac Users:*
Hello. Thanks to AppleMan1958 for answering my question about how to edit an iMovie project
on another computer.
Here is a question related to the process of transferring the iMovie '09 project file from my friend's
computer to an external drive so that I can edit that project in iMovie '09 on my MacBook Pro:
How do I know if my Smart Disk FireLite portable external drive is formatted to MAC OS X Extended (journaled)? How I do format this Smart Disk FireLite USBFLB80C to MAC OS X Extended (journaled)?
When I connect the Smart Disk FireLite to my MacBook Pro via USB, open iMovie '09, and select View
Events By Disk or rather "Group Events By Disk," an icon for the FireLite external drive appears, but there is a yellow triangle with a black exclamation mark on the icon for the external drive. What does this "warning" mean? There are MP3s of music on the same external drive and they open just fine in iTunes. The one iMovie project file that is already on the drive will not open up in iMovie.
So, how do I properly format this external drive in order to transfer an iMovie project file from my friend's computer so that I can edit it on my MacBook Pro using iMovie '09?
Sincerely,
Corey

I bought two Seagate 1TB Barracuda drives and installed them as a Raid 0. This did not change the stutter during playback. I contacted the GPU manufacturer and they said to install the latest driver. They have had several updated drivers recently. I have tried each new one as they were releases with no improvement. Nvidia said I can send it in for "warranty repair". I just paid for the GPU card on October 20th. I tried disabling the audio devices. No change.
I need help and do not know what to do next.

Flash video stutters when using DW's player

I'm banging my head against the wall with this one. I want to
add video to my site using Dreamweavers player. But, the video
stutters during playback. This is not an occasional hang up, it
seems to only play every other frame or so.
This problem has nothing to do with bandwidth or computer
speed. This problem occures when played back locally, AND DOES NOT
HAPPEN with another player. The problem is I do not want to use
another player. I add a lot of video for clients and I love how
easy it is to do that with Dreamweaver.
Here are samples using the same video file, only different
PLAYERS:

I don't see any evidence that you used Dreamweaver to insert
the
player. Normally, when you insert Flash with Dreamweaver, it
inserts
code I can readily identify. Did you use GoLive?
The pages you show are consipicuously missing the
<object> code and
the JavaScript that DW uses.
And I don't see any differences in the players. The pages
both link to
files named flvplayer.swf (in different folders) with the
same look and
the same file size. I am late in this thread, so maybe I
missed the
boat.
Anyway, I don't know if this would make a difference with
that player,
but one page uses a relative link to the .flv, while the
other page
uses an absolute link, including
http://. See if changing that one to a
relative link helps.
I only watched about a minute from both pages and, although
872 Kpbs
for the video track is VERY high, I did not see any glitches.
(Did you mean to use two slashes in the second link?)

AVCHD 1080/50i export to mpeg 1080/50i - video stutters

when exporting the complete sequence to mpeg 1080/50i the resulting video stutters at 2 to 3 points. Thus I exported 3 parts of the sequence: no video stutters. Then I create a new sequence based on the resulting 3 videoclips, export the complete sequences and the exported video stutters again at some points.
Can anybody help?

What version of Premiere Pro? ==> PP CC
Have you installed the recent updates? ==> yes
What operating system? ==> Win 7 Professional SP1 64-Bit
What kind(s) of source footage? ==> AVCHD 1080/50i
If you are getting error message(s), what is the full text of the error message(s)? ==> not relevant
Has this ever worked before? ==> yes, has been working for smaller export files (less than 120 seconds)
What other software are you running? ==> nothing in parallel except security & firewall SW
Do you have any third-party effects or codecs installed? ==> No
Tell us about your computer hardware. ==> 6 core CPU 3,4 GHz, 64GB RAM - 6 GB RAM for other applications
Are you using Mercury Playback Engine GPU Acceleration? ==> yes - NVIDIA Quadro 2000
Does the problem only happen with your final output, with previews, or both? ==> only with the final output - the preview is fine - combining the shorter files (up to 120 sec) to one big sequence (4 min) --> the final export is stuttering at some times (even the export of the shorter files was fine)

ITunes 8.1.1 TV Shows Video Stutters but Audio plays properly

I upgraded to iTunes 8.1.1 hoping to fix a problem I was having. When I pay TV shows that were purchased through iTunes the audio comes through properly but the video lags and jumps. If it is a SD video the lag is a "quick blink of the eye". If it is an HD video it can take several seconds for the video to catch up with the audio, looking like the video has frozen.
• I am using an iMac G5 with OSX 10.5.7 with 2GB DDR SDRAM 2GHZ PPC
• The problem occurs if I open the video with QuickTime too.
• The files are all held on an external HD; but when I copy a file over to the main HD, it still happens.
• I've deleted all iTunes plist files and there are no 3rd party apps with iTunes.
• I'm reinstalled QT 7.6 instead of just upgrading it.
• I've done permission repairs and had 3 issues that were not able to be fixed:
"Warning: SUID file "usr/bin/quota" has been modified and will not be repaired. Warning: SUID file" usr/bin/quota has been modified and will not be repaired. AND Warning: SUID file "sur/bin/rsh has been modified and will not be repaired."
• The video stuttering also happens with movies that I make in iMovie 9.0, although all the files work fine on my iphone/youtube/other computers.
Any thoughts on how to fix this?

Hi hockeymom3,
Have you installed any QuickTime components? If you have, try removing them and testing again.
They are generally located in /Library/QuickTime(Launch Finder> click Go> Computer> Macintosh HD> Library> QuickTime) or ~/Library/QuickTime(Launch Finder> click Go> Home> Library>QuickTime).
This article: http://support.apple.com/kb/TA24166 describes similar issues with Intel Macs caused by 3rd-party components.

ITunes movies--video stutters, then sound cuts out

When I play a video file in iTunes, it starts out just fine, but within a few minutes, the video stutters and the audio cuts out completely. The video will continue playing (although it will continue to stutter a bit) but the audio never comes back. Also, oddly, the search box has a white rectangle in it that covers the blue border of the box. It's a little hard to describe. I've tried a ton of things to try to fix the problem, and nothing's worked yet. It happens unfailingly, and I've tried updating drivers, re-installing Quicktime, re-installing iTunes (incidentally, the problem has persisted throughout several iTunes and Windows updates), and a lot more that I can't even remember. I'm on a PC running Windows 8. Does anyone have any suggestions?

This solution was posted by tmeader on iLounge forums:
You need QT Pro:
1) Open up the Video file in Quicktime Pro
2) Select File->Export
3) Select "Movie to MPEG-4" beside "Export:", then click the OPtions button
4) Select "Video" and make sure that the "Video Format" is set to "Pass through"
5) Do the same for "Audio", then hit OK
6) Save the file
Or you can downgrade the firmware from 1.1 to 1.0:

Yu can get the previous updater at Apple support.

QT audio and video stutters in WinXP - IE7 and Firefox - DSL

Every time I click on an audio or video link on a webpage, QT Player opens to play the file. However, every file it opens - audio or video - stutters in a specific pattern. Each segment (chunk, packet, whatever the unit term is) repeats four times before the next one begins. This renders all files unplayable. Reinstalling has not solved the problem. I'm running the latest updated version of the QTPlayer. I don't know the number, but it updated last night, 3/9/2007.
Anybody have a solution?

Video stutters when setting range in and out points within browser

While playing back video and using the "I" and "O" keys to set range in and out points, the video stutters every time I press either key.
Footage is Apple ProRes 422 1080p23.98 and 720p59.94 (problem is more noticeable with 59.94 footage). Playback quality is set to "Better Performance"
FCPX 10.1.3
OSX 10.9.5
Mac Pro (Late 2013)
3 GHz 8-Core
32GB RAM
Dual AMD FirePro D700
Project stored on 7200rpm eSata drive via GbE

Yes that's exactly right. As I'm going through selecting ranges to mark with a keyword tag, the video pauses for a split second (and skips a few frames) every time I use the "I" or "O" keys. As I tend to tag multiple sections within each clip I like to mark my ranges and tag them on the fly while the clip is still playing.

ONline Video Stutters/Skips [other programs affected]

HI. ive been having this problem for quite some time now; everytime i watch videos online, the video stutters and or skips. i tried everything, fixed my internet connection, wait for the video to load completely, but the problem is still there. these past few days when it starts stuttering/skipping my other programs do the same thing too.
like for example if i was on itunes i cant access it since the cursor wont even move, and if im on imovie playing a video or something, it stutters as well. i have a feeling it's not just about my safari, it's about my mac in general [i hope not]
ive updated all my flash, safari, EVERYTHING. still the prob persists. i cant watch vids online at all!
pleasseee helllppp meee!!!!
[ps: i sing on youtube, and i use youtube instrumentals as music, and i cant really do that with stutering audio in the background.LOL. just sharin' how important this is to me! hahah]

You don't really give us enough to go on, so I'm not going to swear to this, but sometimes you see this kind of thing with a dying hard-drive, or filesystem corruption. Make a backup of any important data NOW to be on the safe side.

DVD Rip and then burn - video stuttering

I'm trying to rip from a dvd (legal) - so I can put it in Final Cut, add subtitles, and burn back to dvd? But so far, I'm getting video that stutters on my final dvd.
I tried to rip the video from dvd using MPEG Streamclip, then edited it in Final Cut before burning a dvd in DVD Studio. But in the ripped video the picture fades in and out.
Then, when I burn to dvd, the video stutters incredibly on a regular dvd player (but not on the computer's dvd player). Anyone know what's going on here?
Suggestions?

I just encoded it using compressor. A little bit of stuttering on the dvd (should I apply a de-interlace filter?)
But still have the problem with a constant color change on the video - is there a different program that I should try to rip with rather than MPEG Streamclip?
Thanks.

Video STUTTERING answer!

I have been plagued in the last few years of my Mac experience with not being able to export smoothly after producing a half hour community tv show.It stutterd, froze up,etc.Thinking it was my eMac, I sprung for a PowerMacG5Quadra and...had the same problem! I was devastated and embarassed at the station.
BUT (and don't ask me how this came to me...a Mac "muse" maybe?) today after having yet one more terrible time with the same problem, I opened my external hard drive,dragged the iMovie6 creation into it and..voila!! It exported beautifully..not a stutter to be seen or heard.
I'm hoping this wasn't an anamoly and that those of us haunted by this can take heart. Thanks,Kate

New! Re: Video STUTTERING answer!
Posted: Apr 16, 2006 7:19 AM in response to: Kate Porter
Kate, where is the iMovie project located on your main drive? In your Movies folder or somewhere else?
Karl,I usually keep them on my desk top? Not good?
How much RAM does your G5 have?
I'm confused over RAM and memory..just know it has about 200GB at this point. I started with 500GB thinking that was a lot...lol! Did I find out quick how video gobbles it up!
Do you allow your Mac to go to sleep at night? If yes, is the housekeeping that's done at night getting done? (If your Mac is always asleep, OSX's housekeeping may not be getting done.)
I do actually..and I see your point. I'll leave it on tonight.
Oddly, by the way,the external hard drive tip I shared,tho it seems to have worked for Gavin, stopped working for me the next day! I could only get one clean export and then it started burping midway... I'm almost thinking,since this has happened to me on BOTH my eMac and my Quad,that I'm taxing the software.Is this possible??
Thanks,Kate
