I used a compression and it made the file size smaller but I'd still like some input on what's the preferred compression on Macs for .MOV files(QT).
I've found HandBrake useful for compressing/converting .MOV files. Especially if you are making any screen captures with Quick Time X.
You can find it
here. Its free and comes in 64bit flavor and uses H.264 compression.
A quick note on its use;
The files it produces are .mp4's but they will have by default the extension .m4v. If you didn't change this before running HandBrake all you need do is double click on the file as you would to rename it and change the extension to .mp4
