I succeeded to rendered further combinations and cleaned up<br>
my file name syntax as follows:<br>

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

<br>
The file quality (sharpness) looks fine against the input hd01.mov<br>
file, the file colors varies a bit between greenish and<br>
yellow-brownish.<br>
<br>
I didn't change the default project setting, just loaded the<br>
hd01.mov file once, and rendered all files from it.<br>
The default Setting > Format color model is RGBA-8bit<br>
Obviously it should have been set to the higher RGB(A)-Float for<br>
this 10-bit 422 ProRes HQ file format?<br>
<br>
<br>

<br>
<br>
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...<br>

<br>
I have re-rendered all h65 files with Setting>Format>Color model=RGB-Float or RGBA-Float and OK.<br>
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.<br>
<br>
Here two examples:<br>
<br>
du -sk hd01_cin_appimage_ffmpeg_h265-<wbr>10bit_yuv422p.mp4 hd01_cin-multi_rgba-float_appi<wbr>mage_ffmpeg_h265-10bit_yuv422p<wbr>10le.mp4<br>
26240 hd01_cin_appimage_ffmpeg_h265-<wbr>10bit_yuv422p.mp4<br>
26268 hd01_cin-multi_rgba-float_appi<wbr>mage_ffmpeg_h265-10bit_yuv422p<wbr>10le.mp4<br>
<br>
<br>
And here follows comparision (diff) of Mediainfo output for the same files:<br>
<br>
