Hi all,
I have video captured on V8 tapes in about 1990. They are low resolution
video. Recently I sent the tape to a profession shop ripping them on DVD. I
have ripped the DVD to computer as .VOB files. On the whole their quality is
not so bad except those video taken in-door then the screen not very clear.
I'm prepared converting them to .mp4 files and simultaneously increasing the
resolution to 640x480 or to 1280x760 to check whether their quality can be
improved? The audio is excellent.
Please advise what command line shall I run? Thanks in advance.
I don't know whether VSR (video super-resolution,

has been implemented in FFmpeg. I'd sure like to know.
VSR appears to use some of the techniques of motion-vector interpolation, but to employ the
synthesized pictures to increase the apparent resolution of the existing pictures, instead. I
haven't determined whether that increase applies solely to the pictures in key frames or to all
pictures (contained in B & P frames, also) in a processing/filter chain.
Regards,
Mark Filipak.
