Put them both on a 24p timeline and render. Vegas will do no-recompress pass-through of the frames, so there will be no quality loss. You can verify this by watching the Video Preview window during the render -- no-recompress frames are not shown, so if you only see black during the render, all is good.

Can you do this with mpeg 2 files? Can you also trim start and end points on an avi without recompression? Is there somewhere I can go to read more about this subject?

No, you cannot avoid recompressing with mpegs. Vegas is designed to edit DV, so the format internally is DV - hence no recompression. An AVI is just a container, it depends on what's in the AVI as to whether it will need to be decompressed or not.

There are some mpeg-2 editors available - www.womble.com for example.

The Womble one looks good. Is that the one you recommend?

I've never used it, so I can't recommend it. However other folks here on the board have used it and it seems to be the one that gets refered to most frequently.

"Vegas is designed to edit DV, so the format internally is DV "

My understanding is that effects and transitions are done in 8-bit precision, but there is no "DV" format as such in Vegas.

I shoot and work with 10-bit uncompressed video, Vegas does not downgrade this when you use simple cuts.

(With MPEG-2 of course there is no such thing as simple cuts, because of the intermediate frames in this format.)
