[MEncoder-users] concatenating two movies

[Gilles Pelletier]

After succeeding in making a movie from jpeg files with:
mencoder "mf://*.jpg" -mf type=jpg:w=640:h=480:fps=0.5 -ofps 30 -ovc
lavc -lavcopts vcodec=mjpeg -o still00001.avi
I am now trying to concatenate this movie with another one taken (as a
movie) with my camera: 00263.avi
Here is the command line:
 mencoder still00001.avi 00263.avi -ovc copy -oac copy -o output.avi
Here is the output:

All video files must have identical fps, resolution, and codec for -ovc copy.

Exiting...

The only difference I can see is 112.1 kbps (13.7 kbyte/s) for the
animated pictures and 9477.2 kbps (1156.9 kbyte/s) for the movie.
Would that be the resolution? I wouldn't think so. What am I missing?
