In the screenshots you posted I don’t see where you select 10bit. How do you know it’s being processed as 10bit?
It could still be processing it as 8bit but then saving it in a 10bit ProRes file. It would only be 8bit info but in a 10bit wrapper.

That’s why I prefer command line because you have complete control of the workflow.

If it outputs a ffmpeg log file you can confirm its workflow with that.

That’s super smart. And you may be right. I’m fairly certain that doing it this way in Hybrid preserves the 10bit during the entire process though. If it didn’t, then I’d be seeing the artifacting that Harmy was seeing when he did the conversion in Media Encoder, as well as the artifacting seen in MPV. But the Hybrid conversion is totally clean. The input file is 10bit, the output file is 10bit, and there’s no artifacting at all. So I’m pretty positive it stayed as 10bit the whole time. But you’re right, knowing that for certain is definitely great. I might have to read up on how to do the command line. But for now, Hybrid gets the job done for me. (Especially with my original workflow of rewrapping to MP4 and then doing the ProRes conversion in Resolve. That definitely preserves the 10bit). 🙂
