3 years ago @eugeniosz You are very welcome for the software. Thanks for using it.
Normally FFmpeg and VideoToolbox can fail when trying to convert a 8-bit video to 10-bit, but a 10-bit-to-10bit conversion should work.
Let me ask the Video Transcoding Hivemind™ if they've seen this before. Stay tuned...

Hi all, I've just tested the command above on my 2018 i7 Mac mini (which can output 10-bit from VideoToolbox as opposed to many other older Intel chips which cannot).
My source was Soul (2020) - 4K version with a 10-bit video track.
The test command run was: other-transcode --hevc --10-bit --add-audio all --surround-bitrate 384 --duration 00:01:00 /Volumes/4K/Soul\ \(2020\).mkv. I'm running ffmpeg 4.3.2 from Homebrew.

3 years ago @eugeniosz Without knowing your Mac, we need to check the following:
- Can your Intel Mac actually output 10-bit even from source? From my testing, the Mac mini (2018) and later Macs can but M1 Macs do not support 10-bit output. I'm not sure when the Macs started being 10-bit output capable so worth checking.
- Is your input truly 10-bit? If you drag-drop the source onto MediaInfo, you should see a "Bit Depth: 10-bit" (as above but from the source). For example: my iPhone 11 Pro is set to 4K/60fps but it's only an 8-bit output. I don't know if the iPhone 12 models upgrade the bit-depth. But the real test would be a 4K movie rip like Soul 4K above.
My guess at this stage is the first one above ... Intel Mac version & (possible lack of) 10-bit VT support Thanks, Joe
Hi Joe, Thanks for your answer. Below more info, I use an iMac 2019 with i9-9900K and AMD Radeon Vega 48 64GB RAM

Hi. I post this here even though I think this could a FFMPEG issue. Applying the other transcode command: other-transcode --hevc --10-bit --crop auto --add-audio all --surround-bitrate 384 /Volumes/MyMovies/HDR10bit_movie.mkv generate the command: ffmpeg -loglevel error -stats -i /Volumes/MyMovies/HDR10bit_movie.mkv -map 0:0 -c:v hevc_videotoolbox -pix_fmt:v yuv420p10le -b:v 8000k -color_primaries:v bt2020 -color_trc:v smpte2084 -colorspace:v bt2020nc -metadata:s:v title\= -disposition:v default -map 0:1 -c:a:0 ac3 -b:a:0 384k -metadata:s:a:0 title\= -disposition:a:0 default -map 0:2 -c:a:1 aac_at -aac_at_mode:a:1 cvbr -b:a:1 256k -ac:a:1 2 -metadata:s:a:1 title\= -disposition:a:1 0 -map 0:3 -c:a:2 aac_at -aac_at_mode:a:2 cvbr -b:a:2 256k -ac:a:2 2 -metadata:s:a:2 title\= -disposition:a:2 0 -sn -metadata:g title\= -default_mode passthrough HDR10bit_movie.mkv it fails with the following: Transcoding...

Also trying with Handbrake (nightly build with H.265 10bit Videotoolbox) it fails.
