I've seen countless tutorial web videos done by amatuers and they all have one thing in common. ANNOYING UNECESSARY LOUD MUSIC PLAYING IN BACKGROUND! Most of them are Rock N' Roll or Alternative, Heavy Metal. We don't care what kinda songs you're into, we don't care if it's your favorite song. Keep that crap off. You think you're cool? It's really pathetic, makes you look like a moron rather than a smart guy, teaching these tutorials.
Tip #1 Don't play music in your bedroom, bathroom or where ever you do your recording while your talking. We can't hear you. Do this and your video will become useless.
