Jan 25, 2010 2:29 AMby step5,Hi!
Thanks for the hint. I am trying to play video recorded with a Sony WX1 (HD 1280x720 pixel 30f/sec).
With Quicktime X it looks like the sound and the pictures are shifted against each other by a couple of seconds.
Thanks to your hint I tried now Quicktime 7 I found in the Utilities Directory and it works just fine.
I can also edit with iMovie and sound and images are synced. -
Mar 5, 2010 12:13 PMby neil1,I'm having the same problem - I have a Pentax K-7 camera with which I take HD (720p) video. My videos always play back very choppy when playing through quicktime 10 on my MacBook. Can you guys there in Apple please sort this issue out - Quicktime 10 is useless to me as is. -
May 19, 2010 11:05 AMby CrispOne,Just wanted to chime in and say "me too." Running QT10 on a MacBook Pro w/ 2GB RAM, and my HD videos won't play smoothly. Really annoying, since I got this computer specifically to work on video. Apple, you have a reputation for excelling at video and audio production. Please hold up to that reputation. -
Jul 31, 2010 8:37 AMby chadguy97,I'm convinced that Quicktime X is junk. I have a MacPro 2 x 2.66 Dual Core with 8 Gig of Ram that used to play everything smoothly with no jitter or chopping under Leopard 10.5 and QT 7 Pro. Now that I have "upgraded" to Snow Leopard, my computer is close to worthless. I'm thinking about removing Snow Leopard next week.
In addition, I have a BRAND FREAKING NEW MacBook Pro 17" with the Quad Core i7 Chip at 2.66 GHz that also refuses to smoothly play HD videos files with Quicktime X.
Seriously, Apple? What's up with releasing software that is substandard when what you had worked great? Scrap QT X. -
Sep 9, 2010 10:08 PMby Shticky,Here's a suggestion. I tried Quicktime 7, it was better, but still choppy. I downloaded a program called VLC for free and played the same videos fine, smooth as silk. I don't have a powerful computer. Someone said it: Quicktime X is junk. Reminds me of the Windows Media Player circa 2005. Apple, you must redeem yourself! -
Nov 25, 2010 10:09 PMby Fatima74,I run Snow Leopard 10.6.5, both Quicktime 10.0 and QuicktimePro 7.6.6 and I own a MacBook Pro (2.53 GHz with 4G RAM). And I have the same problem with choppy and out of sync HD playback. I am finding thread after thread complaining about the same issue with no solutions. It's been over a year since SL came out and I don't see anything about Apple addressing the issue. This is absolutely unacceptable and I feel cheated by Apple for thinking that buying a mac will allow me to work on and play HD media. -
Dec 5, 2010 3:37 PMby genesis2seven,Plus 1 on this. I have 720p videos from both my D90 and my brand new Flip Ultra HD. I just got the Flip and went to look at the first few videos and they were all choppy. Thought I had a defective camera but then I check other videos I had and they had the same issue. I used to watch them fine in QuickTime. Not sure when the issue cropped up but this is ridiculous. Makes them totally unwatchable. They all work fine in VLC. I'm happy paying for Mac precisely for application packs like QuickTime, iLife and iWork but if I'm going to end up using open source apps anyway I'd just assume go back to Linux. This is really disappointing. -
Apr 20, 2011 5:43 AMby jtsternberg,Add another to the list. Brand new 17" MBP with 4 gb ram, and the i5 processor. What frustrates me is that Apple stuff is supposed to "just work." I'm seeing a lot less of that with their later iterations of software. I upload video from my iPhone to iPhoto, and try playing the video with either iPhoto or QT 10 & I get slow choppy video. Of course it works if i switch to VLC, but why would the built in OS not be able to handle playing HD video? It's rediculous.
