I was going to play with converting my GH5 10 bit clips to cineform before editing, but wasn't sure how to go about encoding it. I see it in Quicktime settings, but I apparently have to manually key in resolutions above 1080p (I'm shooting 4K), and don't see any options for high bit depth above 8 bit, though I've heard of people here saying they use it for 10 bit video...
Am I missing something?
You are probably using the licensed (gopro?) version, which is 8 bit, at least in QuickTime libs. Got it listed as a custom AVI renderer?
The codec went open source last year, and IDK if someone has compiled a vfw version, or what options are available
Same settings are available under AVI. A few encoding presets (filmscan1 is default), the option to 4:2:2 or 4:4:4 or 4:4:4:4, but no bit depth options.
Perhaps for my needs there is something better. I'll try the XAVC-I out. I think it does support 10bit.
That's the route a lot of folks are taking, if you keep it in Windows. I guess ProRes for portability.
An overlooked legacy AVI encoder that handles gargantuan resolutions is Helix. At 444 RGB 8 bit, It should be roughly the "equal" of 10 bit YUV.
Do you need an intermediate or a proxy? ie, are you trying to interact with another program or just looking for timeline performance?
Cineform endodes in YUV422 10bit, RGB 444 12bit and RGBA 4444 12bit.

You can use the free Virtualdub2 (new virtualdub filtermod) to batch encode your files with its native cineform encoder (based on the cineform sdk)
Problem is you can't get the 10 bit out of Vegas because MagicYUV uses vfw api.
