Sony Vegas taking forever to encode to mp4

[ArtOfLosingMFZB]

So I'm currently encoding a project from Sony Vegas that's a little over two hours long (about 2:15) and it's taking a VERY long time to encode the video. I'm outputting to mainconcept/avc mp4 with a main profile at around 1,500,000 to 2,000,000 bps and, so far, it's been encoding for 9 hours with an estimated 17 hours to go. Is that normal??? Is there a way that I can encode this thing quicker? I would have exported it to uncompressed AVI and then encoded with meGUI, but, in my experience, those uncompressed files are way too large and I don't have that kind of hard drive space. On the upside, it doesn't seem to be hogging much of my CPU, as I'm still able to browse the net.

Oh, yeah, and I also enabled two-pass encoding which I'm sure is doubling the render time.

depends on your computer. list it's specs in your profile. any effects/filters also increase rendering time.

I updated my profile with my computer's specs, but I'll paste it here as well: Windows Vista, Intel Core2 Duo CPU - T5800 @ 2.00GHz, 4GB Ram, 250GB HDD

I don't have any effects/filters in this project, strictly cuts.

sounds like a laptop maybe? what video card?

[ArtOfLosingMFZB]

Yes, it is a laptop, with an ATI Mobility Radeon HD 3400 Series video card.

you might want to try rendering with the cpu instead of a laptop gpu. click custom while in the render as template and select render using cpu only.

It doesn't give me that option. I'm using Sony Vegas Pro 10, do I need to upgrade to 11?

[TreeTops]

Your Vegas render custom screen doesn't have 'encode mode' on the bottom?

[aedipuss]

when using vegas pro 10, the mp4 encoder you need to use is the sony avc/mvc type. the mainconcept one is crippled. vegas pro 11 went back to the mainconcept avc encoder.

Ahhh, okay, yeah that was my problem. I was using the mainconcept instead of sonyavc. I am an idiot. Thanks for all the help.
