I think he made some good points. What's wrong with learning the technical aspects of video and audio? I've been a hobbyist for several years now, so I don't claim to be an expert. I watch some hunting shows that I can't believe are being shown on TV. Panning way too fast, zooming way too fast, very shaky video, camera noise on the audio, etc. The same thing goes for some of the hunting videos I've watched.
I don't know if it's just me, but it seems like some people think they can get a camera, shoot some footage, and sell videos without knowing a whole lot about it.
There are a lot of online resources for video. A lot of what I've learned about editing and taping I've learned from forums on the internet along with reading a lot.
Yeah, maybe a little harsh, but some good points.
