I am confused as well. I did not look into the code base, as it appeared too many times there, inclusive unused code. Instead, I searched for the string in the plugins with "motion" in the name in the bin/plugin/video directory. There the only one was motion2.
I also did a no_vaapi h.264 .MP4 render test now using the renderfarm, because I was not getting 100% CPU. With 8 client renders on the same machine as the host, it rendered twice as fast and CPU was 100% all the time. Very likely 3 clients would have been sufficient. Anyway, the file size was also as small as without using the renderfarm. I am _guessing_ that witH pure software rendering, upscaling the frame rate from 50 to 120 has a lot of duplicate frames, which pure software rendering detect and therefore decodes as very small differences. I don't have high-fps source media, tried to find some but so far all raw or non-downloadable. And there are multiple raw formats, I wonder how to distinguish between them. I took a short look at the blank frame problem that the freelancer's patch should fix, but have not yet duplicated it. later. Also, I saw weird things using the interpolate video effect, later too.
