[FFmpeg-user] Changing scan type (progressive<->interlaced) without reencoding.

[Bouke (Edit 'B)]

It’s no problem at all.
Btw, it’s very common to store progressive as interlaced, as broadcast still requires interlaced material, no matter how it is shot.

From memory, just do a -c copy and you’ll end up with the source in a progressive container.
