Quicktime render unusually LARGE

I'm still using Vegas 5 ('cause I dig that vintage sound ;-))

I had a request from a client to take a 5 minute (20MB) Windows Media video clip and convert it to Quicktime. Easy enough, I thought.

I was able to easily import it into the program, then "Render As" Quicktime.

A couple hours (!) later, it finishes, but the finished Quicktime file weighs in at 13GB!

What did I do wrong??

No doubt you rendered an uncompressed QT file.
Choose a template, or make your own custom settings.

That was it. I don't normally use Quicktime, so I was in a bit of uncharted territory. Thanks!

I always have a ton of issues with sound and aspect ratio with QT. Here is what works for me:

I render out of Vegas in dnxhd ( the free avid dnxhd lite codec ) in either 720p or 1080P (dvcpro works too). then I open that in QT pro and export that to H264. when I do that, sometimes I have to set the resolution to something like 853 X 480. You'll need to test it. Sometimes it depends if it's going to a PC, and Apple, Youtube or Vimeo. QT doesn't seem to encode aspect ratio very consistently between platforms. When even I send QT uncompressed I get no audio......

Ducking for flack.........

As a guideline, I've rendered a 7 min running time QT H264 file that came out to something like 500 meg. (note: had this way wrong originally)

You are absolutely correct. Quicktime rendering in Vegas supports 1:1 PAR only, as far as I've been able to determine.
