Even on high bandwidth connections it's annoying. My read speed is much higher bandwidth than videos for things that can be explained in a paragraph or three.

Even on high bandwidth connections it's annoying. My read speed is much higher bandwidth than videos for things that can be explained in a paragraph or three. Videos should probably be used when: 1. Your audience is non-technical. 2. A (moving) picture is worth a thousand words (eg, words can't do it justice, but a quick video can). 3. You're not bandwidth constrained (or firewalled). 4. You're not just video'ing text entry, or if you must, you ensure the user can zoom in or enlarge the video to see it (the embedded video can't be enlarged, I had to open it in Youtube to actually see it).
