Test Render Codec

I am ultimately outputting to DV.. What is a good codec to use for test renders that are low-res, full frame-rate and takes very quick to render?

Stick with DV. I can't think of any reason to use any other codec for your test renders. It renders faster than just about anything other than uncompressed AVI, and takes up a lot less space.

Set up a custom DV render template that uses the "preview" render quality setting. Up to 16 times faster render than the "good" setting. You won't get any resampling, even if you have it activated on clips. So any speed changes might not be as clean. But it will render speed changes in real time this way. Picture quality wise, I've only found the deform filter will show a difference between the two. Just a slight stair stepping effect.
Now I need to ask why test render? Vegas is solid, whatever you see in previewing the timeline is what you'll get on final output.

This particular project uses LOTS of layers.. many of which are hi-res Photoshop files (upsampled for the sake of scaling in Track Motion).. many of which have multiple VideoFX.. It slows the preview to a slide-show framerate.. This is the only way to see the true behavior of a lot of the motion effects.

As an aside, I have since discovered the 'Build Dynamic RAM Preview' feature which seems to satisfy this need.

But as a secondary aim, I'd like a codec that is small enough that I could feasibly fit 5-10 minutes of footage on a CD-R and give it to a musician I am collaborating with.. simply for the sake of syncing up stuff. The idea being is they take the low-res footage, make changes to the .veg file in the context to music they are creating, then return the new .veg file to me, and I substitute high-res clips into the Media Pool.
