Slow Render Times........Help...

Gentlemen, I need your help... I have a 2 Gig Board with 512 Ram. I use Vegas 4.0. I am running XP Pro. 40 Gig primary, 120 For Video Editing and an external 120, all 7200 rpm IDE. A recent render atempt took 7 hours to render 11% of a one Hour basic compilation, 6 Tracks with no complex transitions or keyframing. What can I do to improve my render times. What settings affect the render rate. I terminated all unessential processes and Disabled my anti-virus. What else should I check...?

Thanks in advance for your help...

Hugh

What effects and compositing are you using?
Have you reduced the levels of any of the tracks?
Are you using velocity envelopes or time stretching?
What format are you rendering to?
What format are the source files?

I've found that "pre"rendering some segmants as DV AVI's and reimporting them REALLY speeds things up. I don't mean using the pre-render option, but when you make some comples fades/effects, if you render that section out as a DV AVI, then re-import it and replace the old stuff with it (and saving as a new VEG file!), you will save time. Well, technicaly not really, because you will of rendered it anyway, but instead of rendering everything forever, you can render everything in small bits and ren render them all at once in no time flat.

Basic Overlap transitions of footage captured from DV tape.
No track levels have been reduced.
No Time stretching or velocity envelopes
I have tried NTSC DV and MPEG2.

Note: when I attempt to prerender the program came back with 327 render points or segments....

Post your VEG file somewhere so we can look at it. Maybe we can see something you are overlooking that would slow it down.

You can mail your .veg file to testbench@vegasusers.com if you want me to post it on my server.

The problem seemed to be that I used an overlay that ran the entire length of my 1 hour video as well as many transitions. Over 372 render points. Once I prerendered the video the render whizzed by in realtime...

You have track 5 set to 98.7%. This slows things down a bit. Is there any reason you don't have it set at 100%?

Also, when you render, are you selecting a loop region only so that you're not including the mpg2 tst render on tracks 8 & 9 and all the blank space before it?
