in the foreground. Vegas provides sophisticated compositing including green screen, masking, and key-frame animation. Nesting allows a prior project to be included in another project, modularizing the editing process so that an array of tracks and edits become one track for further editing. Any changes to the previous project become reflected in the later project. Nesting is especially helpful in large, complex or special effects projects, as the final rendering suffers no generation loss.
