This error is because you are running the "movie duplicate" command before any video frames were recorded. The "movie record" command is not like a live screen capture. It only records when frames are rendered and that only happens when the scene is changed. So if you use "movie record" then rotate the view with the mouse, then "movie duplicate 10" will work since you will have already recorded one frame. But ChimeraX movie recording is almost never done by hand-typing commands and moving things and changing the scene by hand.

Movie recording is typically done by putting commands in a script file (*.cxc) and loading that file rather than typing commands by hand. The reason for that is it gives precise control of how long each motion and scene change takes.

Here is a tutorial that gives an intro to ChimeraX movie making.
