<div dir="ltr">Thank you so much. I think rerecording the morphs is my best option. I wonder however if there's a way to reset the molecular movie to start after each time I play it using coordset.

My experiments just now suggest even “max framerate” may not have much effect on how fast the morph looks in interactive playback. I think you will need to use approach #2: go back and create the morph again, but with more steps. That will slow down the motion during interactive playback (as well as in a recorded movie, if you make one).<br>

How can I use perframe to play the movie and introduce a wait of a few milliseconds in between frames thus controlling the speed of the molecular movie?<br>
