ScreenEdit is no match to Apple's QuickTime Pro. Nonetheless, Just like QuickTime Pro, ScreenEdit lets you edit QuickTime movies by copying, cutting, pasting and trimming frames. It also lets you re-compress QuickTime movies with such QuickTime built-in compressors as Animation, DV, H.264, MPEG-4 (Part 2).
An exclusive feature of ScreenEdit is Split. ScreenEdit allows users to split an movie into upto 19 segments in equal length plus another one with remaining length.
