While trying to render some of my new videos for upload on YouTube with Sony Vegas Pro 9, I encountered a problem where the rendering process would crawl to a stop after 1% or simply freeze. Well, I found a quick solution around it, that is to render it in MP4 instead of AVI.
This works really well btw, now I can do a 20 minute 1080P video rendering in about 5 minutes.
Use the above screenshot settings and change the frame size to 1920×1024 pixels for 1080P. You can also try the above settings for 720P, which should be pretty good also.
Btw, my first short film with Canon 7D is almost done uploading!
