120fps video files won't open on Ventura 13.4

I also converted with Handbrake to exact specs of the original file and that worked. Only downside was the obvious conversion time. I had a 110 files in the Queue and it took like 15hrs or so and thats with a spec'd out M1 Max MacBook Pro. So for me that was a bit better than downloading the Beta. Just a different option.

Hey man, I downloaded “wondershare Uni converter” had to pay around $90 it converted the footage to 60 frames and still 4K. It’s obviously time consuming but it got me out of a stuck situation.

I did find 2 fixes.

1: premiere pro . somehow the videos are working once imported into premiere pro

2: a software called handbrake which is used to convert and compress files. it works offline and is free. you just convert the files that doesn't work and they start working. there is a full tutorial on YouTube showing how to use handbrake

I did indeed offer a solution. Roll back the 13.4 update using your Time Machine backup.

I see that this is fixed in Ventura 13.5b2. Another option would be to use Adobe Premiere which worked for me to get something out quickly.

Ventura 13.5 is the solution we all needed! <3

13.5 b2 fixes this issue

13.5 b2 worked! Thanks so much.

Same here! Apple this is absolutely mind blowing!! As most professionals, I did do my research, but this is a very specific issue that I would expect to work. I never found this issue until i searched the EXACT issue. Basic video playback? I understand these are high frame rates but this is not unusual.

To anyone reading with this issue, this is where I’m at with solutions until apple fixes:

1. Adobe Premiere reads my files. I will most likely be continuing in here until Apple has an update.
2. If you had proxies made in FCP prior to updating, those still work. May not be ideal but if anything export it out, lean into the lower quality and throw some VHS fx on it and reexport after the proxy export.
3. VLC can convert video, but I’d recommend premiere over that!

You have to be part of the beta testing program. 13.5 beta 2 is a test version not for general release. It’s not that hard to download and install but you have to realize that it’s beta release and while it might resolve the issue at hand here it could also create other problems. Your choice.

Apple Beta Software Program

Having the same issue on my M1 Max laptop. I converted the files using Handbrake but there was a significant reduction in quality. I'm unable to finish projects that I've been working on for months. Apple please fix this.
