You needn't apologize at all, your help is very notable.

Wow, I didn't know about this: it solves my problem even much more better.

Timeline-editing is exactly what I asked for, but you wrote me about even 
better solution (previous note).

So in other words both solutions are excellent but the first is better ;-), 
marking as SOLVED. Many thanks to everybody, you solved the problem faster 
than very quickly.

P.S. Sorry for keeping you waiting so long for my answer, I had to unmask 
newer version of ffmpeg first (in Gentoo ffmpeg-2 is still marked as 
unstable), recompile it and test both solutions (I didn't have a usable mixed 
record with both progressive and interlaced frames /big compression prevented 
from detection of interlacing/, so I made it from two).
