I'm using a Mac G4 with QuickTime Pro iMovie, and I have Final Cut Pro 2 and Sparkle (not very familiar with video editing). I have 15 second mpeg video clips from a Sony digital camera that I need to edit (color/brightness/cropping) that I need to take to the web, cross-platform. .Mov files don't play well for me in Windows environments, and I want to create compressed mpeg files. The edited mpeg files encoded with Sparkle are about 3 times the size of their .Mov counterparts (too Big).
Is there an encoder, plugins, software, yada, that you know of that will help me accomplish my tasks?
