The following do not work and all get the same type of error messages: pfm.pfm, phm.phm, qoi.qoi

Hm, i tried those with just 1.qoi filename, and you tried with %d type ? i also set render type to single frame, and you tried range or in-out points?

I set render to whole project, but the input was my standard hockey.ts test case. I will try a different video.

They do work when I do "single frame". Is that what it is supposed to only work on? If so, I will just add a comment to those 3, saying for "single frame only". What do you think?
