Sorry if that’s a silly question

A few pixels over a session IMHO doesn’t constitute dithering
Dithering moves each frame in a “random pattern” by anywhere from a few pixels to 20 or 30 pixels each frame, a session could be 20 to 100 frames
Each dither is random too
Hope that puts it into perspective
Maybe others can offer more advice and explain in more detail too
