I'm rendering some longer movies that have long sequences of duplicate frames, eg: Molecule side view (5 seconds) Rotate/Zoom (3 seconds) Another view (5 seconds) I've noticed that when using the mpng command, these duplicate frames are rendered, one after another... Is there a setting I'm missing? cache_frames doesn't seem to prevent the behavior, and is unusable for longer movies. If not, may I humbly suggest this as a feature request? It could reduce rendering times significantly. I've debated scripting the duplication of a single frame post rendering, but I'm not sure it's worth the extra work. Thanks, -Nick |

Hi Nick, Unfortunately, there's nothing you can do about it. mpng just writes out the frames one after the other, with raytrace_frames set raytraycing each of them. cache_frames just puts each (rendered) frame in memory, so Pymol can cycle through them sort of smoothly after all frames are rendered. It has nothing to do with your problem. The only solution is to script the duplication or to write some python script to handle the moviemaking/ raytracing/ framewriting. It would of course be nice to have Pymol recognize that from one frame to the other the scene did not change and hence the same image could be written to disk again...
