[MEncoder-users] skipping/jumping in video when cutting sections

[Adrian]

Hi,

I'm trying to use mencoder split a clip up and join
sections of it together out of order.  Wherever a
join happens in the video,  I get a skip or jump in
the footage.

For example, The resulting video from the syntax
below will skip at the 20s mark.

mencoder \
 file1.avi -ss 10 -endpos 20 \
 file1.avi -ss 30 \
 -o output.avi

#  file1.avi [10..30] + [30..end] will end up in output.avi

Can anyone suggest a way to avoid the skipping in the output?

Thanks,
Adrian.
