Thinking about starting a YouTube channel

[DaleCooper]

One thing that will make it hard to watch a channel is bad audio and almost every channel starts out with bad audio, so get a good microphone.  If you're going to be a talking head, get good lighting too.

I'd add that if you can't get good lighting, then start without the talking head and just use really good b roll. Archival footage of real events is always fun to watch in documentary-style videos.
