New Export Settings Option for H.265 10 bit in mastering

Is your feature request related to a problem? Please describe.
There is no way to MASTER a proper 10 bit output in h265. this one addition would be so great.

---

Describe the solution you'd like
output in much high quality ProRes and use Handbreak to convert to 265 10 bit master.

---

Describe alternatives you've considered
non-master options. But the master 10 bit h265 would be higher quality than the non-master versions.

a) h264 is not defined for either 10bit or 422 (banding is reduced by the color sub sampling, not necessarily the bit depth – so 422 is more important than 10bit), that means, FCP cannot export this due to only using hardware (GPU) backed codecs. h264 in 10bit and/or 422 needs software 'hacks' which are slow and inconsistent.

b) what you are looking for it x264 which uses DITHERING to remove banding. 10bit 422 is NOT supported on the web anyway (only for HDR HEVC formats in special use cases as you already discovered). to get x264 use the free shutter encoder (handbrake is not so accurate and has too many settings that impact the files), turn OFF hardware encoder use (see screenshot) and feed a prores (only export prores to guarantee full quality, HEVC compresses dark areas heavier than h264 even).

you can use my x264 youtube preset for the best settings and no banding when coming from 10bit 422 footage. drop it in username/Shutter Encoder/Functions and click the 'star' in shutter encoder to activate

I've been discovering this over the last few days that 10bit h264 is basically a hack. So, I get that. Thank you for explaining. I was getting to the point of posting that myself.

Basically, What I'm seeing is that under "Mastering" export options, I'd like to see 10 bit h265 and possibly 12 bit h265 options. I don't have enough hard drive space to render these files in ProRes for quality. h264 isn't enough.

there is 10bit HEVC if you use apple devices/social media or computer. the latter is very close to a master file but also compatible with windows (important). what you'd like to see is under 'video and audio' (where you can choose prores) to have HEVC in addition to H264 with a 10bit option. you can already just use compressor for this (if you have it). send a project to compressor and use your custom preset or a build-in one. no interim render step needed.

you've summed it up perfectly. I don't have compressor.

The settings for h264 under mastering is different than social which is different than computer. HEVC 8 bit, 10 bit, and 12 bit under Mastering seems like a critical option without Compressor, just as a base line. This is 2024. Not 2019. These options are essential to HDR output and Wide Gamut at the mastering level. I consider this a BUG rather than an enhancement. But as you wish.

It also seems equally overly Aggressive for Apple to NOT have any "audio sample rate" dropdown for export. Even audio mastering doesn't have any options, period. I get that apple put that in Compressor, but man, it's not even the bare minimum. I'd really like to be able to select between 48khz and 44.1khz for the output of the audio without having to buy Compressor, or changing the project settings to do different exports. Again, this is almost 2025. Apple is behind.

Updated the original request to make more sense. The Mastering export really could use a 10 bit 265 for highest quality.
