[Chimera-users] Save as GIF (animated or otherwise)

Thanks Cristina! That's pretty much exactly what I'm looking for (I guess
the ppms or pngs can be converted to mp4 subsequently).

It doesn't seem to work though when entered under the "additional encoding
options" section of the "Record Morph Map" dialog (as "movie encode
resetMode keep"), I guess either it only works in a script or I am using
the incorrect command.

Re the transparent background you mean for movie frames or regular still
images? For the latter the "Transparent background" checkbox in the "Save
image" dialog works fine, for the former I am not sure.

Cheers,
Oli.
