- Are you using adaptive sampling? If not, use it. Also, you can often get
- very good edges (for video at least) by using Low Anti-Aliasing with a
- threshold of 20-30. Experiment before rendering out the entire animation.
- Using Adaptive Sampling and the edge threshold causes a selctive resampling of
- only the image areas that have higher contrast and are therefore more likely
- to show jagged (aliased) edges. This is probably a gross oversimplification,
- but it is the basic idea.
