does anyone know a good guide how to denoise mpeg2 videos, which come from VHS videos, recorded with DVD-recorder?
I assume you're stuck with the captures you already have, yes? (Most of the issues come from the analog world and ought to be fixed there- a TBC on the playback deck output, capturing YC outputs if available instead of composite, cleaning the playback heads :), etc.)
One thing that can help is covering any head-switching noise at the top or bottom of the frame that with a black bar before re-encoding; sure, you'll lose a couple of lines, but they're garbage anyway and can confuse the encoder. Might mask a px or two on the L/R edges of the frame, too.
