Hello Guys!
I'm experiensing some real strange (to me) problem.
I have to extract portions of a video, let's say, one second.
I use
ffmpeg -i origin.mxf -ss 00:00:00.000 -t 00:00:01.000 -c copy -map 0 -y
chunk.mxf
What I get is this:

Seems ok lookin at duration, but the frame= 16 is really strange since the
video is at 29.97fps...

The video has ony 0.53s, or 16 frames more or less...
I tried setting the fps by hand, using -to instead of -t but nothing
changes...
Does someone has some idea about it? What am I doing wrong?
Thanks and Best Regards
