Question about converting to a movie file

Does anyone know how to turn a Blender animation (or export it) into a movie file or any kind of file that can be played in Quicktime or Final Cut? I’m on OS X 10.5 and I’ve tried everything: changing the codec to Quicktime, changing the codec to AVI raw, naming the tmp/ folder, pressing NTSC in the format panel. Everytime I hit “Anim” it renders but shows up nowhere on my drives. The exporting options don’t include NTSC, MPEG, Quicktime, or HDV. They’re all formats I’ve never seen before. Guess I’m out of answers. All guides and tutorials are pretty much for PC, but even so, still don’t seem to explain how to do this very thing.
