join could mean several things:
* you are trying to merge the two files, so you end up with 2 video
streams and 2 audio streams concurrently, with the length of the
output file being the maximum of the length of the two inputs
* you are trying to concatenate the files, so you have 1 video stream
and 1 audio stream, with the length of the output file being the sum
of the length of the two inputs
(as mentioned in the FAQ:
I suspect the latter:
Your videos are of different sizes, so that may cause problems (or
maybe not, I don't rightly know).
