What "video techniques" have you seen help keep learning fun?
What works and doesn't seem to work? I know everyone learns very different, but I'm looking for a overall general "visual video techniques" used that really works. Any special animation effect? Does subtitles help or does it distract the watcher from what's on screen? Certain pop up effects? Basically, how does one maximize the learning capabilities of using videos as a teaching medium for the general population?
