RE: help please - Selur - 09.05.2026
Side question: Why even care about Primaries and Transfer when using PNG output?
I will probably remove them from the ffmpeg call since they should not have any impact on the output. => nope I leave them there, too much trouble to remove them and for the decoding they might make sense.

tbh idk, learning as i go it might make zero diff
RE: help please - Selur - 09.05.2026
Those are flags for video not images,...
As a side note: just uploaded a new dev, which allows overwriting input color primaries and transfer under "Filtering->Misc->Overwrite input"

That's a bug, I introduced during refactoring.
=> uploading a new dev which should fix it. (will be up in ~10min)
