[chimerax-users] crossfade issue

[Elaine Meng]

Hi Omid,
I've never seen this problem, but I always make my window the same size as I want for the movie beforehand.  In case it is some kind of confusion between dimensions or aspect ratio of the window vs. the movie images (only a guess), I'd recommend doing this instead:

windowsize 640 480
movie record supersample 3
wait 60
crossfade; cartoon hide #1/D-F; wait 60
movie encode framerate 60 output test.mov

What you sent wasn't quite enough to reproduce your situation, since we'd also need the structure, display styles, current window size, etc. (e.g. you'd have to send a session file if you're willing to make it publicly available).  If so, instead of sending a message here, use menu: Help... Report a Bug and attach the session file as well as the commands that you sent below, and a description of the problem.  That also lets us know the ChimeraX version and type of computer you are using.

I hope this helps,
Elaine
