anyway to save edited file WITHOUT rendering it?

Hello, everyone, I'm new to this so forgive me if it's in the manual(could not find it). I'm using the ATI AIW 8500DV and capturing to MPEG2 at 8000kbps and bough VV3.0a to edit out portions and before saving it to DVD.

Is there a way to edit out portions of the mpeg2 file and either save it to the original or to a secondary file AS_IS without rendering it? the real problem is that the Ulead Video Studio 6 program I bought *insists* in rendering and converting it to the .vob format before it burns it, when all this is done and said I can spend 8 hours just to do one show.

If anyone from SF reads this , can we add this to a wish list?

just the cuts, save and don't render?

while at it can we get more multi-processor support within this program? I have a second 1800+MP just sitting idle and feeling unused ;) and a easy way to set it so it grabs as much time slice from the OS as possible

Hmmm. I'm gonna guess the answer is no. MPEG files are very complex in that frames can refer backards and forwards in the file to "fill in pieces" of themselves. You can't just chop a piece out of an MPEG file and expect it to work. If you did, the frames immediately preceeding the cut and probably quite a few afterwards would be scrambled, and i imagine the sound syncronization would probably be lost too.

When Vegas renders the file, it converts each frame into a fully self-contained picture, and then regenerates the MPEG compression from scratch to avoid the above problems.

Uncompressed AVI and DV files can be processed efficiently in this manner though. If a section of the source material isn't being changed or processed in any way, Vegas will simply copy the frames to the output very rapidly without having to re-render them.

If you capture your files as .avi, Vegas will render cuts-only projects to the same exact format without recompressing. If you are using a format that does not contain all the frame data in every frame (e.g. MPEG, .WM) then we always recompress.

hmmm, i was allways curious about that. Glad to hear that is the case.

thank you all, guess I'll have to get a RAID card next that works in the 64 bit slot/66mhz and get a couple of drives and stripe together 200 gigs to record 2 hour shows

to be fair I just test drove a program from down under that does *cut* a mpeg2 file to a clipboard and then let's you render just that piece. but for 695.00 guess I'l go the hardware route

I was searching the forums for an answer to this question, but I'm kind of disappointed to discover the answer. I'd been hoping for something equivalent to VirtualDub's Direct Stream Copy, which works very nicely for this task, except there are some formats it doesn't handle, probably for copyright reasons (e.g. .wmv files).
Even for .avi files, it would be nice if there were a "same as source" checkbox in the "Render as..." dialog, rather than having to explicitly specify all the details (things like the audio sampling rate and bitrate, for example). Or am I missing something here?
