Until now I've been rendering to uncompressed AVI then MP4 via Quick Time with H264 codec. Great quality but time consuming.
I'd like to render staright to MP4 from Vegas and notice there are two options (Main Concept and Sony) - is one preferable to the other?
More importantly, I can't adjust the size, which is set at 320 x 240 (the custom button is greyed out). Is this my version of Vegas? I'm using Sony Vegas Movie Studio Platinum 7.0.
