Hi. I am having a problem that was working before I had to reinstall my Windows 10. I have MOV files that were recorded on an Atomos Ninja V, and I was able to open open them in Vegas Pro 17 until recently. I did go into preferences and selected deprecated tab to enable Quicktime. I also installed Quicktime from the Apple site, and from the Vegas support page (they look the same). I can get sound, but no video. I also can''t play the MOV files in Quicktime, just sound and no video. I am able to play the files in freeware programs like VLC media player just fine. I think there is some switch in Vegas that I might have forgotten? Any help will be greatly appreciated. It sure would be awesome if Vegas would support the Prores codec that was just released in March for Window apps, but you can only get that in Abobe video products right now, and Resolve is working on it. You can download the beta codec now.
