Is your feature request related to a problem? Please describe.
Due to how dark my video is, there needs to be a greater bit depth to capture more gradients of deep grey. There is too much banding in the regular 8 bit encoding options, both in H265 and H264. But there is literally no option for H.264 10 bit. 10 bit output is only in H265, which is not supported by odysee, tiktok, x/Twitter?, and others. YouTube and rumble does support H.265.
But the only way to get H264 10 bit is to export in H.265 10 bit, then use Handbreak to convert it to H.264 10 bit.

Describe the solution you'd like
Relabel existing H264 appending" 8 bit" and add "H.264 Single-pass (Faster) 10-bit" and "H.264 Multi-pass (Better) 10-bit".

Describe alternatives you've considered
The only other option is output as H.265 10 bit, and use hand brake to convert it to H264 10 bit.
