I will need to start encoding to H.264 format for downloadable video products. I know Sony Vegas can encode from the timeline to this format, but I also am aware of other encoders available for purchase. Does it benefit me in any way to use a different encoder than the one Vegas uses? If so, which would you suggest and why? My starting format will be AVCHD 1920x1080 and probably scale down to 1280x720. Thanks!
