I did a bit of casting about on the Internet in an earlier post on creating video. Here’s a shorter, more focused list. I haven’t explored all the topics at the first site, nor even tried many of them, but there is much good advice and many useful tips. Also, as I get going, I’d like to move up to a richer experience and a more interactive one for the viewer. That means thinking about Camtasia or options, and something that replaces Zaption.
