rendering to Mpeg2 takes 12 hours for 10 minute clip

Hello All,
What is the average time to render a 60 min. v4 project to Mpeg 2 to prepare it to burn in DVD architect?
It estimates about 12 hours for a ten minute clip. Are there settings that I need to change to make it render faster.
Computer is HP 734n
512 mb Ram
80 gig HD
64 g-force video
vegas 4a
p4 2.4 ghz

Thanks in advance,
Jack

Did you let it go for a while before you stopped rendering it? It usually takes Vegas a good 5-10 minutes for it's time estiate to level out and give a pretty accurate reading. IF your video starts out with a lot of titles and effects, Vegas thinks your whole project will be that way so it estimates time based on that. I just did a video about a month ago that was some Hockey game highlights for a local high school. When I started to render it it said it would take about 9 hours when it started, but once it got through the opening titles and effects it quickly dropped, I think the final time was like 45 minutes, and that was for a 30 minute tape.

Actually,
I forgot to mention that the project is actually a slideshow with alot of movement and sonic plugins effects (photos are jpg format).... Do you think that would be a reason for the long render time?
Thanks,
Jack

If you are rendering to MPEG2 directly from the timeline with jpegs and lots of pan/crop/track motion, then that could definitely be a contributing factor. You might try rendering to an avi first and then bring that avi into a new project and convert that to MPEG. I don't know if that would help or not, but at least you'll be able to see which part of the process is causing the slow down - the pan/crop stuff, or the conversion to MPEG.

yup, that is your problem, any time you have lots of effects, transitions, color corrections and stuff it will increase your render time, although 12 hours does seem like a long time to render a 10 minute clip, I would bet that it won't actually take that long to do. My suggestion is to make sure your computer is well cooled, maybe stick a fan in front of it, and just let it render overnight. I have had to do that many times with long renders.

If I have lots of effects and/or transitions, filters etc. I always like to render to AVI first so I can view it unimpeded on the TV for one final check to see if it flows and looks as expected. Also, rendering to an AVI allows me to then do a quick print to tape to do a backup of the final project.

Then I render to mpg. On my Athlon 1800 a DVD-NTSC mpg2 in Main Concept takes about 2 times the length of the avi.
