Why do you need to make interlaced from progressive?
Excuse me to jump in.
For example, when encoding for BD I need to make the choice between
1080i to retain resolution, or 720p for ease of handling.
(Although I never had to used FFmpeg for this task)
If you have good reason (and 50/60 fps source) then you also have to
be careful around chroma conversions and any scaling filters for which
may get auto inserted and break chroma (cause it to bleed between fields).
Is there a technical term for this phenomenon, or any resources I can
read further on this? Hopefully one aimed at video operators rather than
codec designers...
Thanks.
