Hi Yanhe,
I'm not sure what you are trying to get (or what you expected) from that command.

None of those commands are multi-frame actions spread out over time.  Only the mclip command changes the display, but it does so in a single step, so even if you put wait (which should be at least "wait 1") after it, you would only get one frame:

movie record directory ./my_movie pattern Movi1-* fformat jpeg; mclip #0 offset -1 slab false; wait 1; movie stop

Movie-related commands, including several that can have multi-frame actions:

Or maybe you wanted several frames recorded while nothing is happening?  Then you would need to include larger numbers of frames in the wait commands, e.g.

movie record directory ./my_movie pattern Movi1-* fformat jpeg; wait 50; mclip #0 offset -1 slab false; wait 50; movie stop

I hope this helps,
Elaine
