Im a bit of a noob at this but have about 2 minutes of footage i edited in Imovie , to save it as one file i went to share save for cd or whatever that option is and it saved. The 2 minutes of footage is like 300mb is there anyway to compress this. my friend said use fcp to compress the file that or compressor which came with it . Not sure which type to compress to mpeg4 mpeg 2 (whats the difference) also in compressor what does all the 120min 90 and 60 min things mean. Once again any help would be greatly apreciated thanks.
