Bash also stops at the ';', it is a command separator. It is like
entering two commands like this:

videosplitcmb -x -iorg.mp4 -t0
1768 -t2420;2972 -otest4.mp4

You have to escape the ';', like this: '\;'


In fact, if "videosplitcmb" is your program, it doesn't even see the
second part, it is bash who stops at the ";" before calling "videosplitcmb".
