[FFmpeg-user] Deinterlacing VHS

[Noeck]

Hi,

I have digitized VHS video recordings on my computer. The Video is
originally recorded in a PAL system (interlaced). I would like to
improve the video quality with some filters. Cropping and color
correction is clear.

But deinterlacing is hard, as the lines of the half-images are not
exactly one pixel apart because the resolution is not identical with the
analogue resolution on tape. The framerate should be like on tape. yadif
does improve things a bit.

Is this just an ill-posed problem or are there special settings to
achieve a good deinterlacing in this case?

Are there any other recommendation how to improve visually percieved
quality for typical VHS videos?

Cheers,
Daniel
