Greetings-- I am not a video pro but I sort of fell into making a bunch of videos about how to shave (don't laugh, I have over 1 million total views on my Youtube channel). I use Foodtv's "Good Eats" show as inspiration and guidance and I see the host, Alton Brown, narrate various cooking guides both on camera and off. Are there any "rules of thumb" regarding on-camera vs. off-camera narration?Â
