I have rendered it in .avi, .mov & mp4. I have been editing footage for 1 year plus with this same pc, I built it and it is more than powerful enough. All this trouble started when I would render the footage and it would only produce the audio. Well I had to reset all the settings to default to fix that issue and now I have this one. I have had a buddy to capture and render the footage to a pc with Vegas and a MAC with Final Cut and it was fine on thier end. I grabbed some footage off my second angle camera which is a Kodak Playsport and edited it real quick with the Kodak software and rendered it and it was fine. Both cameras (primary camera is Canon XHA1 and second angle camera is Kodak Playsport)are running 1080i.
