I'm using VapourSynth/Other/BasicVSR++ to restore a DVD source. The output has noticeable temporal inconsistency – the background jumps every few frames, especially in long shots.
I suspect this is due to chunk processing. Increasing length to 150 makes those 150 frames coherent, but the jump reappears exactly between frame 150 and 151. It seems the model doesn't handle boundaries well.
Is there a way to process with overlapping windows (like a sliding window with crossfade) to smooth out boundary jumps? Or any other recommended approach to maintain temporal continuity across groups?
