5D render settings to maintain original format
 

Hi Folks

I have 1080p footage from a Canon 5D. Once edit is complete what settings do I render this footage with so that it remains in its original format and hence is least taxing on the computer.

e.g. when I edit with DV AVI footage I can render the timeline back as DV AVI and there's really no "rendering" taking place, it just stitches the edited clips together and takes hardly any time at all.

How can I achieve this same technique with HD footage from 5D cameras? What format do I render in?
