I don’t know how you are looping, but if I use View… Loop in Quicktime Player, I don’t see any pause in the movie created with command script:
rock y 10 68;wait
rock y -10 68; wait
movie encode ~/Desktop/test.mov
… also your commands are a little weird because rock will already change direction, so you get an identical movie by running a full cycle of rocking, e.g.:
rock y 10 136;wait
movie encode ~/Desktop/test2.mov
If you are using some other method of looping, maybe it is repeating the end frames. I don’t know if this “View… Loop” display in Quicktime Player goes from the 136th to the first or assumes they are the same and goes to the second instead.
