@shotcut, Could you explain me then why SPR with 100% zoom (thus neutral, not changing anything with scaling) and used only for y scrolling, causes such quality degradation? Shouldn’t be like that if zoom==100% then no scalling is done? And why when setting 100% as zoom, sometimes it’s not possible to set position and size as 0:0 1920:1080? but there is one or two more or less as values?
