really (and i mean REALLY) long mpeg render times.

Another questions about the computer I'm setting up. :)

I captured an AVI file with Vegas (uncompressed, 640x480, upper fields, 44khz, 16 bit, stereo), and when I goto render it as an mpeg-2 file (640x480, upper fields, 5 mbs, 44 khz, 16 bit, mono), it take 30 minutes to render a 1 minute clip. I've reduced the quality slider down to 20, but then it still takes 15 minutes to render. I'm rendering on an AMD XP 2600 (333 bus), 512 mb DDR333, and have 3 seperate 80gb drives. I've tried rendering onto each drive with the same results. i know there's something I'm missing because on the other editing computer I normally use, I could render a 1 minute clip in 3-4 mintes (AMD Athlon 1ghz, 100mhz bus, 256mb PC130 ram)

ANY help would be greatly appreciated! Thanks!

I'm venturing a guess here, but because it was uncompressed doesn't Vegas have to re-render it as a compressed avi before converting to mpg? Were you using an uncompressed file on the computer that only took 3 or 4 minutes per minute?

Why are you rendering a MPEG-2 to 640x480 instead of the default 720x480?

To both your questions:
Paul_Holmes: You're right. On the other computer i use DV Compressed AVI's. That might help (less info for the mpeg compressor to sort through).

BillyBoy: The TV station is using a special MPEG player to play commericals over the air (TV). The MPEG player only supports up to 640x480 resolution. I belive it's a Soloist Duet. I forget who makes it. I did try using a 720x480 MPEG but the results were horrible: looked worse then rendering the fields backwords.

Well, I updated Vegas to 4.0b and not I render a 1 minute clip in 2:20 minutes :) That's from uncompressed AVI video too.
Oh, I found out the maker of the MPEG player at the TV station. It's Adtec Digital.
