Hi, Sorry, as you have seen, “movie” doesn’t have the transparentBackground option that is available with the “save” command. <http://rbvi.ucsf.edu/chimerax/docs/user/commands/save.html#image> <http://rbvi.ucsf.edu/chimerax/docs/user/commands/movie.html> Chimera had a “bgopacity” startup option, but as far as I know this has not been implemented in ChimeraX. I can imagine possibly using the “save” command (with transparentBackground true) as a “perframe” action to manually script saving all of the individual image frames, and then using a separate program to encode the image frames into a movie, but it would be a lot of work. Alternatively, there may be programs able to post-process your solid-background movie into a transparent-background movie, but I haven’t investigated or tried to do that myself.

Hi, I have succesfully created images with transparent background, but it seems is an impossible task for a movie. Is there any way around this? Thanks and regards, -- Dr Norberto Escudero Urquijo Prof. A. Warren's group Cambridge Institute for Medical Research (CIMR) Hills Road, Cambridge, CB2 0XY
