Anyone have an answer to this - or are there any encoders that will skip recompressing sections of an MPEG movie on the timeline that don't don't require additional rendering for effects, etc?

Thanks

What you need is a simple MPEG2 editing program (and not an encoder). You can use TMPGEnc for simple cut/join, and there is also a slighlty more capable program called Womble MPEG-VCR (the MPEG2 version). They both will not re-render the entire video file, if all you do is cut pieces.

Ulead Mediastudio can do this, I wish Vegas could do it too..

Vegas -- or at least DVDA -- should do this. I have many captured MPEG clips (from my AIW 8500DV card). I want to simply cut certain scenes and then put on a DVD. I can put these into DVDA and it creates the DVD without re-rendering. I can cut the beginning and end of an MPEG file, and DVDA will create the DVD without re-rendering. However, if I want to cut something out from the middle, I either have to edit it in Vegas (which results in re-rendering as noted in the original post), or I have to put TWO instances of the file onto the first menu in DVDA which results in two titles. This is a pain to navigate because the DVD format requires the DVD to go back to the Title menu once a given title has finished running. You cannot have the two clips (even though they originated from the same file) run consecutively without stopping back at the title menu and forcing the user to press buttons.

Thanks for the info. Unfortunately, I don't have DVDA - I'm using Dazzle DVD Complete to assemble my DVD's. This program has worked quite well for my needs.

Nevertheless, as an answer to my initial post mentioned, TMPG has the ability to cut and assemble existing MPEG2 files without re-rendering. I've tried the evaluation copy and it works great for simple cuts and assembly jobs.

Go to digital-digest.com and you'll find several joiner/cutter prog for mpeg2. Biggest prob doing this sort of edit is that you're limited to ending/starting a clip to the closest I frame.

If you do use TMPGEnc, I recommend encoding your MPEG files using CBR instead of VBR. I kept getting glitches when cutting and joining VBR MPEG files in TMPGEnc.

Vitec also has a very good editor for mpeg (as well as a ac3 stream editor) that can edit on I frames and P and B frames (re-encodes only that GOP).

there are a few others as well (not many)

The Vitec program looks good, though it is rather expensive
