Unresponsive/Laggy Quicktime Player

[stevearm]

Ever since updating to Sonoma, Quicktime Player has become almost unusable for me. Whenever I try and rewind or fast forward, there's a delay and going back to regular playback always results in a delay of a few seconds before it finally goes to normal speed. Sometimes it'll even jump straight back to where I was before hitting rewind/fast forward.

Updated to the latest .3 version and it hasn't fixed the issue. Any ideas ?

Quicktime also crashes my Studio Display whenever I play anything on it but that's a whole other issue!

Thanks in advance for any thoughts people might have

I am having the same issues, especially the bolded issue.

QuickTime Player has always been a limited video player. It still doesn’t play mkv files.

Wouldn’t be easier to use another player?
IINA https://iina.io
VLC https://www.videolan.org/vlc/download-macosx.html

Neither do your proposed alternatives play _my_ media files.
The issue at hand is not about alternatives (yet), but the failing of a standard Mac application.

In my case, M Mac Sonoma QuickTime doesn't loop correctly, it stutters. It's unusable for work. Had to use an M Mac with Ventura upon which we ran that version's QuickTime.

This (and a lot of other macOS 'weirdness') should have been seen by the developers while programming, should have been seen and acted upon, during initial and beta testing. But no...

Can you use a previous OS version of Quicktime in Sonoma? I didn't know that!

Awfully sorry! I realized to late how it could be interpreted. No: we use an M Mac with Ventura and run QT on it (will edit post).
That said, long time ago, I recall we once copied and used an older version from a previous OS. But that's in the mists of time. You can always try

What media files does QuickTime Player play and VLC and IINA do not?

You can copy-paste QuickTime Player from a previous macOS version and it will most likely work in Sonoma.

Good question. In my case neither QT or any replacement can play some of my (old) media files. Some are predating QT and the rest, i.e. we created our own. No known standard agreed upon, that came later. Others are memory dumps created during testing or presentations. They can only be shown or played with similar programs which created them in the first place. The program decides what to do with a blob of bits, which is being fed to it. Sometimes we transferred them for general distribution so they can be played by QT, VLC and others.

I'm getting stutters in Quicktime after updating from Ventura to Sonoma 14.3 this week on my m2 Pro Mini.

Also, stutters in QuickLook views of videos.

Quicktime is just plain broken for me in Sonoma. I'm surprised more people aren't talking about it but it seems to just be isolated incidents, which is weird, even a fresh install of the OS makes it screw up.

I use Quicktime for quickly trimming videos. I don't see that ability in IINA or VLC.

I take it you have done a safe mode boot then back to normal mode to clear up the OS? It helped a lot on my stuttering Magic Trackpad on my iMac M3.

Update: 14.4 Magic Trackpad 2 is much better. Not 100% but way better than before.

I haven't used Quicktime for anything but playback. So as an experiment, I threw about 20 little snippets of videos that I created from iMovie years ago of family videos. All 720p. Wanted to combine them in one big QuickTime file in Mov. After about 15 min of the gray spinning wheel it wasn't showing unresponsive. No Force Quit option was coming up. Then the iMac screen froze, turned pink and shut down! LOL. Rebooted and got that unexpected restart pop up to send the report and I did. So yeah Quicktime in Sonoma and new iMac M3 with 24gb of RAM, 2TB, is still just for your basic playback and maybe quick trimming or combining little files. Other than that I wouldn't touch it again.

I use FFworks but that LosslessCut I may try also. Thanks.

FFWorks handled 30 files easily. Merged them using a VToolbox Hardware encoding. Total of 2 hours in about 12 min or so. QuickTime locked up my Mac, turned the screen pinked and hard shut down when i tried using QuickTime to merge files. 😬
