120fps video files won't open on Ventura 13.4

If these are your production machines and critical to your work then why did you just install macOS 13.4 without doing some research and testing. Professionals set up a test system machine, or on a partition, and test their software before updating.

Pleading now for Apple to fix things may take awhile. macOS 13.4 is likely one of the last updates before a new version is released.

Same thing happened to me. First I thought it was a bad batch of Sandisk Extreme Pro 4tb SSDs. The only app that can show the content of the clips so far is EditReady. I haven't got to paid $100 for a subscription to explore a complete solution to the issue but the point is that most of us video editors who need to deliver a product need to sit and wait for a new update? Going crazy here. Last week all my clips at 120fps were fine. After the updates, all gone.

Iam facing the same issue. I shoot almost all my works in 4k slog 3 in 10bit. now none will play in finder and as soon as I import them into fcp the clips goes black. I don't know what Iam gonna tell my clients. dear apple please fix this immediately

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

Same issue all my 10 bit 422 Sony SLOG 3 4k/120 footage is bricked with QuickTime preview as a black screen! Audio plays after a few seconds or so, but not working anywhere. DaVinci studio says the footage doesn't even exist. That's what alerted me to a problem in the first place. It was loaded footage that I knew was working before I did a Ventura update 13.4 which was actually supposed to be video codec updates, but it definitely messed something up. Apple please fix ASAP! at least 6 projects all with content shot in slow motion I need to get done. Bringing my computer in to get the OS downgraded is not an option and I don't have an intel based Mac to run the downgrade. Please help!

Ok Ikrupp, you are here to let us know how dumb we are. We got it. You are so smart you must already be retired. Go enjoy your family. Show the world how good you are at surfing, skiing, rock climbing instead of coming here to state the obvious and make people feel worse than they do. You are not here to offer any solution or to share a similar experience.

Hey everyone, same problem, Apple please fix the issue, we all have to get our projects done

Apple engineers aren't here. We're all end users like yourself. Tell Apple about your problem via Feedback - macOS - Apple.  

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.

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!

And again, to prevent this happening again on your production hardware take the following advice.

1. If enabled turn OFF auto-update on your business Mac
2. Do not immediately install a newly released update. Wait a week or two and research any problems users are reporting.
3. Before updating your business Mac make sure you have multiple (more than one) backups of your important apps and files.

The same advice goes for updates to your production software. If an updated or new version is released either wait to see what others say or have a test system in place to make surest performs to your specifications.

You will save yourself grief and anxiety. Look before you leap, as the old saying goes.

Has anyone installed Ventura 13.5.2? Are there still problems with the files in 100P?
I use Resolve. Thank you!

I'm sure that several searches had been done from a lot of people here. All the creators were unanimous on the fact that this update brings very good aspects for video editing. If you have the budget to scrap a computer for testing, great.

The truth is, you can't expect your videos to fail to open after an update designed for video editing...
