[MPlayer-users] TELECINE or not TELECINE?

Thu Oct 9 11:57:16 CEST 2003

Hi list,

I have some pretty big (about 700MB) mpg-files that I want to encode
in divx to save space.  However, mencoder prints messages about "3:2
TELECINE" and "Progressive seq" every few seconds (logfile attached).
Using -ofps 23.976 or the pullup filter doesn't change anything.
Mplayer prints the same messages, but the video looks fine.

Can anybody tell me what's going on here?  Can I do something about
it, or should I simply ignore the messages and encode it just like
that?  The output looks ok, but I want to make sure I don't screw up
anything before I delete the mpg-files...

Thanks,
Rainer
