Answer 2

During the FINISH-save/rendering part, the editor is given the liberty to choose the format and size w/c is dependent on the end-use=> youTUBE?, celphone? burn to DVD? just play on pc?.

The software has normally a default (e.g., what is usually best? for pc playback) and if the editor doesn't overide this, the software will usually save in big files..avi or wmv format .
