editing .mov clips with Adobe Premier and resaving as .mov increases file size.. why?

seems like when i crop a quicktime clip, the file size should decrease, but premiere substantially increases the file size. I am editing 30 fps clips, and exporting as 15 fps with sorenson 3 compressor at ~80% quality, and it is still bigger file size.

thanks

Premiere is natively 576x720 AVI DV PAL(NTSC in states) so anything you import is automatically resized to that format, with attendent file increase size (you'll note that your imported clips need to be rendered first) so you are not actually resizing the orginal clip, but resizing an upscaled version of it.

Quicktimes H.26x formats are very efficient and widely compatible. You may want to uprade to quicktime Pro in order to get the required codecs, in fact upgrading to Quicktime PRo would let you do all of your editing and resizing with Quicktime. Its probaly the best £20 you can spend on video editing.
