Maybe my request is not related to dvd-backup, but I don't know a better place, sorry for that.
I have some vhs tapes from my video performances I like to convert to mini-dvd. After capturing the results are too noisy to use a bitrate under 4000kb which most standalones can play. In fact a rate about 2000 is needed to burn 30min of video plus some menu and sound specials. Compared with standard dvd-clips that should be no problem because the material is not high resolution everywhere.
So I've started working with spatial and temporal smoother and achieved results in the right direction, but didn't hit the target. Due to the threshold strange pixel appeared at the border between smoothed and original material.
What I understand is that threshold is a kind of step function which decides what to do with the pixels(smooth or not).
Isn't it possible to write code that uses a linear or better quadratic curve function and blend between original and smoothed pixel? This should avoid strange pixel and more smoothing is possible.
As attachment there is an example picture. I'd like to use strong smoothing in the cloudy background and a lot of untouched details in the middle.
I think this should help other users in the upcoming worldwide tape2dvd challenge.
Any other help is welcome,
