Here’s my third try at an introductory video. I’ve added captions in case people with hearing problems can’t access the audio. And sometimes you just can’t hear well on a mobile device; so it makes sense to provide subtitles. Producing them in iMovie is fairly difficult, however, and I am not sure I could put them in a five minute long video. But I may figure out a way, perhaps with a different program. My one regret? I now see I should have made them bigger? Oh, well. Next try.
