Jazu, doing that is a serious mistake.
Vegas re-encodes every time you re-render, further dropping the quality.
Think about it. A one hour AVI file is 13 GB. A 1 hr. DVD is 4.3 GB.
Something has to give to drop the file size that much and it's the
picture quality.
You can try using programs such as Womble or Video Re-Do for this but,
as far as I know, you 're limited to straight cuts with either if these.
This is why anyone serious about editing either saves the original AVI
files (hard drives are very cheap these days, even in Canada) or saves
the source tapes, project file and capture log and reloads the project
if necessary.
