Hi,
does anyone know a good guide how to denoise mpeg2 videos, which come from VHS
videos, recorded with DVD-recorder?
My goal is to reduce the bit rate as much as possible.
From my view, the most disturbing is the temporal noise.
Some few videos in "long play" recordings too show heavy blockin

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-

Did anyone ever write a TBC filter in software?
It might be a bit dependent on picture content, but it strikes me it ought to
be possible to do something that would match up the horizontal position of rows
of pixels by minimising contrast between adjacent line

My question is not about head-switching effects, it mainly is about
temporal noise. E.G., there is the hqdn3d filter, which can do both,
spacial and temporal denoise. But I'm missing some guidance about
using the parameters and in comparision to other
