I have so far been using VMD to create visualizations of molecular trajectories. However, I find myself not entirely satisfied with the quality of the resulting animations—when you want to do snapshot-by-snapshot movies, the simulation "moves" too quickly.
Additionally, I sometimes receive individual graphics images, and need to convert those into an animation. Since I worked on OS X, I've tried both imageMagick and more recently the built-in iMovie. However, I'd like more flexibility in the available movie formats than imageMagick provides, and more command-line interface control than iMovie offers.
So, what I'd like to know is, are there other visualization tools that can either:
- given a MD trajectory, can produce the snapshots and an animation of the complete trajectory with more control provided than VMD; or
- given a set of snapshots (in TGA, TIFF, PNG, etc.), can produce animations in multiple formats (MPEG, M4V, etc.)?
