Hi!

I've been using vMix for a few years now, and I don't think I've updated Windows or vMix the entire time. I do this because the system isn't on a network or the internet, and I want a stable environment.

Prior to lockdown, I was recording out to ProRes as a regular thing, and using the resulting files to edit then on Final Cut on a Mac.

Over the lockdown, I didn't boot the vMix system at all, and switched to Premiere Pro on my Mac. I also upgraded my MacOS from Sierra to Mojave.

Now, when I try and view the ProRes files, they take foreeeever to load into QuickTime, and there is no audio. Also, once loaded, the files don't play, I hit play and they stay on one frame.

I've tested these new files on an old Sierra installation, and they have the same issue. And my old files using the same method work fine.

What am I missing? Can anyone explain what's happening? Is there a setting I changed a year ago and forgotten that would cause this?

Any help appreciated
