There are two reasons for running through the camera:
1 - It removes sync issues. There are delays inherent in the analogue to
digital conversion for both video and audio. When they are separate
input streams, sync is not maintained and drift between the end result's
audio and video can become noticeable.
2 - We already mix a house feed on an analogue sound board. It is
trivial to add room mics to this (not run out to the house mix) and run
the result to the camera, no extra equipment required.
