render times!!!

I have a P4 1.6 with 256Ram an hour long avi. take my box about 3 hours to render an Mpeg2 (main concept) Is there something I can do to make this go faster??? (This is why I like audio) Video is so darn hungry for number cruntching. Is there stuff that runs in the back ground that slows vegas5 down? The only thing that I have checked in the preferences is "disable dual processor support" since I don't have it. should I just leave it unchecked.? or buy a gig of ram. I dunno???

rendering takes alot of time. if you have dvd architect, you should render your video and audio in a dvda template. if you don't, when you bring the media over to dvda, then it will take longer because dvda has to re render again. rendering always takes some time. i do all my big rendering at night when i am asleep

Getting a faster CPU would help. Disk speed may also be a factor since rendering is very I/O intensive, but in your case a faster CPU would probably help much more.

There are two things that are similar: rendering, and encoding.

Rendering is what Vegas does to combine together the video from multiple events, whether they are on the same track (when overlapped, they have to be rendered at the overlap points) or on different tracks.

Encoding is what happens when the video must be changed into a different format, usually from AVI to MPEG or WMV. In this case, the software must look at every bit in every frame, and often compare it to bits in previous and future frames. This is a killer of a compute task. With the excellent MPEG-2 encoder in Vegas, you can approach real time encoding with a 3 GHz computer, if you are not also doing rendering (i.e., if you start with nothing but an AVI file that is the result of a previous render operation, and do nothing but encode it to MPEG-2). Of course, if you simultaneously render AND encode, then it is impossible to predict how long everything will take because some render operations can take hours, even for just a few minutes of video.

RAM will generally not help you with render or encode operations. It can however, be quite useful in making timeline operations go faster, especially if you use a lot of high-resolution still photos.

Thanks guys. I guess for now I will be plagued with long render/encode times. I purchased Vegas5+DVDA2 bundle in hopes to make it faster. I have not tried redering in DVDA format and then the audio. I did try to render as an AC3 but that took as long as would the video. I quit the process. I would expect the AC3 only render would have been quicker. I was wrong.
I love Vegas4 and 5 they ROCK but my learning curve is real slow in DVDA so what I've been using is uleadsDVDWorkshop and when it comes time to burn a disc I check the box that says leave all compliant MPEGs alone. THis makes a dvd in half the time. I don't know what it does but the dvd looks great.
Is there an option in DVDA2 to where it will leave the MPEG alone and not re-encode it again?
