I recorded bunch of video with iPhone 3GS and then edited a 12min quicktime movie from the clips. Problem is that the file size became HUGE, 1,24GB!!! 

How can it become so large file? Even one of the raw clips was 15min and 399MB.
I just wanted to export the movie (with quicktime) to my Mac with the same quality as the iPhone recording quality. Here´s the quicktime export settings details that I exported the movie:
-Compression type: H.264
-Frame Rate: Current
-Key Frames: All
-Compressor quality: Best
-Encoding: Best quality
-Data rate: Automatic
Filter: None
Size
-Dimensions: Current 640 x 480
Sound
-Format: Linear PCM
-Channels: Stereo (L R)
-Rate: 48.000kHz
-Render settings: Best
-Sample size: 16-bit
