This is very useful. I am assuming that you are Mr. Safety on Youtube. Thank you very much.

Some issues....

Vegas 7 does not give a 1MBS template option. I set it to 3MBS and then changed that to 1MBS on "Internet/LAN" using the custom settings.

I have vegas 7 and so can use AVC/AAC and have been but the quality after rendering is a lot worse than my camera.

RESULTS

The results appear to be no different, either on my computer or on youtube, than the "MAIN CONCEPT (AVC/AAC) *.mp4" default setting that I was using previously according to Youtube's instructions. THe AVC settings do not seem to allow 30 fps (only 29.70) or to set 1MBS (only half that.

The strange thing is that the video quality is both worse that yours and worse than the mp4 straight out of my digital camera (casio exilim p505) is far better. I guess that this is just because there are more pixels when it is coming out of my camera. But I can't understand why your videos are so much better quality. If I have the quality in my camera that is going to waste, why can't I compress (or whatever) less than you are doing to achieve a simlar result as you are achieving?
