Is it possible? Sure, just setup each source clip as a sequence that has the audio feed you want for that shot and leave the tracks linked so that you cut between both video and audio. Is it advisable? Probably not. People are far less used to changing of the audio scene they are watching. Video creates kind of a disconnect between the scene we are ...

The Mainconcept or Sony codecs in Vegas are subpar for low-bitrate output such as needed for HTML5 use. Use ffmpeg to generate your HTML5 videos.

So as long as whatever you're shooting can update and refresh at least that quickly, it's not important to do much better. Even shooting a mechanical metronome will probably get you as close as anything else. The refresh rate of the display ...

According to the Using Commercially Available Microphones section on page 76 of the manual for the HF G20, it should be possible to connect a stereo microphone to the external mic connection. There may be some problem with the kind of a source you are using or the way you are connecting it.
