This is the stuff from which screenplays are made. Increasingly, I develop characters and dialogue for many of the corporate projects I work on. Even corporate stuff needs to be entertaining, so there's lots of opportunities to use humor. Training vignettes need real-life dialogue. Plus, unlike spec screenplay writing, you get to see the results on the screen.
Many corporate videos rip off established TV genres.
News magazines, MTV, mysteries, talk-shows, commercials, Mission Impossible. You get to have fun with this stuff. You get over the blank page syndrome in a hurry. Grind it out or go broke. The money is not great, but with enough clients, it can be livable.
