Never would I light these dudes or slow myself down with external mic. It's just dangerous. So I shoot EVERYTHING in auto preset and create what I want in post. I use only the camera mic when shooting motorsports and don't so much as drag my sticks out of the closet.
I do not normalize or use compressors with audio. I manually change levels as needed and once married with music and sound effects and stingers, it becomes seamless. I do a lot of color grading in post and often I stabilize shots in post as I shoot everything hand held, usually quite high on adrenaline.
Watch for Street Freaks on Velocity! :)
