Each dither is random too
Hope that puts it into perspective
Maybe others can offer more advice and explain in more detail too

Understood. To clarify I’m talking about a flexure movement of normally around 15 - 20 pixels over a single session of maybe 80 - 100 frames and then often combined over several sessions where the total can be 30 - 40 pixels. Like I said I might be missing something but i’m assuming a fixed pattern noise is fixed to the chip and as long as the signal moves but the noise doesn’t for enough frames over a given total then it will be recognised as noise and be removed. I would assume that dithering is only benificial if there is almost no differential flexure movement thoughout the entire session(s) ?
Not discounting what you’ve said Martin. I’m just trying to establish a greater understanding.
