Dear Ratbag It is not the editing per se that creates larger internet video files but the difference in image complexity between adjacent edited frames or scenes. Cutting from a busy city scene to a busy landscape scene, with lots of visual elements and components puts more stress on the video & audio compression software and hardware - requiring more data per frame to convey the images. In comparison, a simple unedited talking head or a shot of a barren artic landscape has less video complexity and requires less data to convey. However, that all may be a mute point depending on your compression software parameters. Usually compression software is set for a certain bandwidth - say 600 kbps. So no matter how complex your edits or scene composition, the file size will be the same - instead, the quality of the compressed video will change as the image varies in complexity. A single talking head will look the sharpest while the complex city scape may have compression artifacts and blockiness. If you are comparing an UNEDITED and uncompressed avi video file to an EDITED and uncompressed avi video file, the edited file may indeed be larger. However, once run through the compression engine with same bandwidth limits, the final file sizes should be similar. The difference will be image quality - not size.
