iPhone 4 jumpy video playback

I imported using Image capture, and the quality was bad, and then I imported it into iMovie, and the quality is great.

It is incredible that Apple doesn't pay attention to this issue, it is even more incredible that you have a device that take pics and videos and you can't not play them easily on your pc for an expensive device and you are not able to enjoy it, hard to get support, no way to get ahold of them thru email or chat, where i live there is no apple store, and to call them would cost big bucks and frustration since you have to wait long time in order to get a hold of a human voice.

really DISSAPOINTED, i should have bought something else.

It also does the stuttering and jumpiness when I import it into iMovie. It's impossible to edit when it does this. I have to go back to my old video camera. Very disappointed in this.

Again I tried another opening of my latest videos.

Listen Apple - FIX YOUR QUICKTIME!!!!!!!!!!!!!!!!!!!!!!!!!!

I run it in quicktime and it jumps every second. One of the worst video players ever.

I run it in Total Video Player AND VLC media player and it runs smoothly.

So hopefully Apple can hear the cries of dissatisfation from users like us. If it ain't broken, don't fix it. But since it's Quicktime that's broken, then darn well fix it! It's not just 1 or 2 computers, it's growing like an epidemic!

I have this issue, but it seems to be isolated to videos that were imported from an iPhone 4S via iPhoto to a Mac. When I take a video from the iPhoto library and import it into an iMovie '11 Project, when I hit PLAY in iMovie it "skips frames" (probably 2 or 3) every second. Audio is out of sync, but picture quality is excellent.

When I step through the iPhoto-imported frames one at a time in iMovie, trying to find out how often it has "dropped frames", surprise: there are none. The images are there, in perfect order, from frame to frame with no skips. Hit PLAY, it jumps again, sometimes in different spots.

When I connect the iPhone 4S to the Mac with iMovie '11 open and import directly into a New Event (and make sure iPhoto is OFF), the very same clip from the iPhone will play on the computer with no skips or out-of-sync audio. It takes a long time to import, though...33 minutes for 15 minutes worth of HD video.

My OS is 10.6.8, QuickTime is 10.0, iMovie '11 is 9.0.4, iPhoto is 9.2.3, so this may have been fixed in later software revisions.

iPhone internal playback is "Stabilization On"?

I noticed something after directly comparing clips played back on my iPhone with the same clip imported into iMovie '11 (which fixes the "frame skip" sync problem). The iMovie playback looks the way it actually is with a hand-held video camera: a little shake and vibration. On the iPhone 4S, the same clip has been smoothed out, as if it were a regular camcorder with "Steady Shot" turned on. So I think the iPhone playback hardware has some kind of automatic Steady Shot feature, which you lose when you export it out of the phone.

So, if you're complaining about shaking, not actual skipping and sync issues, when you say "playback is jumpy", try the Stabilization feature of iMovie. If the clip is already in your Event Library, select it, open the Inspector, select Clip and press the Analyze Entire Clip button. Or, you can have the Stabilization analysis done as you import, though this takes time.

I uploaded my Christmas video to iPhoto and when I played it it really looked choppy. I then opened the same file with Quicktime player and it is smooth. I followed the recomendation given by another person that suggested to go to File-> reveal in finder-> original file. After opening it with Quicktime the file plays without the choppiness

I have a solution to this problem of jumpy playback in iMovie OS X.

Problem: I have a 2011 MacBook Air with iMove '11 (version 9) and a newish iPhone 5. I captured video on the iPhone, edited in iMovie for iOS on the iPhone, and then imported into iMovie on OS X. Video playback was not smooth inside iMovie OS X, with annoying jumping . However, there was no problem when playing clips from QuickTime.

Solution: Optimize Video. In OS X iMovie, select all of the video clips inside the Event Browser, right click (or control-click) and select "Optimize Video - Full (original size)". My videos then played smoothly, and I could continue editing in OS X iMovie.

I imported 3 projects this way, and 2 had a problem. It seems like the clips that had the problem had a yellow number in the lower-lefthand corner (which indicates the frame rate which is different from the project frame rate)

I'm trying to edit video shot with a 4S from a few years ago and also have this problem with jumpy playback and in some cases for a few frames the screen goes green.

The problem is that I have already deleted these from the phone and they only exist in my iPhoto. Am I screwed or has anyone figured out how to fix these after they've been downloaded and deleted from the phone?

This is an old thread, but came across it because of my jumpy playback, and I wanted to report my solution. Video is from my new iPhone 5s, imported to iPhoto '09 on my Summer 2009 24-inch iMac (with Snow Leopard OS 10.6.8). Playback is in QuickTime Player 10.0 -- either through iPhoto or opened directly in the Finder -- and leads to short freezes in the picture while the sound keeps playing and the picture then jumps and catches up. Odd solution: Toggle to Full Screen playback, and the picture is just fine!

OK. It looks like Apple Quicktime has been altered. I just got an update reminder to download ver 7.7.5.

I downloaded it, installed and now the videos are not jumpy at all.

Could it have been fixed????
