Thanks for the help. I was able to play a movie and save it, but there 
is still a problem.

What I did was:

open animnew.pdb coordset true

graphics rate maxFrameRate 2

movie record format png

movie record directory Movies # Doesn't seem to do anything since no 
frame files (.png) saved there

but then if I try

movie encode framerate 2 quality higher output Movies/DemoMD.mp4

chimerax gives me an error that no frames have been recorded.

If I do

coordset #1

a movie gets recorded but with the default options. The only way I got 
my options in movie encode to apply was to execute the movie command in 
the middle of the animation playback before it ended, but that excluded 
a few frames at the end and is clearly inconvenient.

How do I record and set the encode options at the same time?

Also, is there a way to save the frames as .png files in a directory?

Thanks,

Aleks
