    but how they look visually? I found it a bit strange how h264
    compresses to different sizes yet h265 is all the same.. you
    tried with rgb(a) - float project setting in all cases, yes?

    The file quality (sharpness) looks fine against the input hd01.mov
    file, the file colors varies a bit between greenish and
    yellow-brownish.

    I didn't change the default project setting, just loaded the
    hd01.mov file once, and rendered all files from it.
    The default Setting > Format color model is RGBA-8bit
    Obviously it should have been set to the higher RGB(A)-Float for
    this 10-bit 422 ProRes HQ file format?

I think yes, there even was bugreport about it but back in time it was said fine-tuning project settings (from auto/default at media load) is user responsibility...

I have re-rendered all h65 files with Setting>Format>Color model=RGB-Float or RGBA-Float and OK.
I'm not sure this is right or wrong, because all h265 file sizes and Bit rate become still practical the same size as with RGBA-8.

Here two examples:

du -sk hd01_cin_appimage_ffmpeg_h265-10bit_yuv422p.mp4 hd01_cin-multi_rgba-float_appimage_ffmpeg_h265-10bit_yuv422p10le.mp4
26240    hd01_cin_appimage_ffmpeg_h265-10bit_yuv422p.mp4
26268 hd01_cin-multi_rgba-float_appimage_ffmpeg_h265-10bit_yuv422p10le.mp4


And here follows comparision (diff) of Mediainfo output for the same files:

diff hd01_cin_appimage_ffmpeg_h265-10bit_yuv422p.mediainfo hd01_cin-multi_rgba-float_appimage_ffmpeg_h265-10bit_yuv422p10le.mediainfo
