[ccp4bb] Generate high resolution pirctures in pymol

[yang li]

Hi all,
    Can somebody please help me to generate high resolution movie files for
secondary structure of proteins? After I ray a model with high resolution in
pymol and then save it as movie frames, the high resolution and ray seem
lost. I have tried the command likes ray 2000,2000 and it does work for a
single frame, but can anybody tell me how it could be extended to say 40 or
80 frames of a movie?
    Your suggestions are highly appreciated. Thanks in advance!
