You should see a footnote "This video made exclusively for drumbeat.org" appear right away
You should see a subtitle "this is a subtitle" appear at 1 sec away
Popcorn subtitles appear on top of the video at specified times.
Popcorn footnotes are lines of text that can be placed anywhere on the page and styled with html as you wish, like the large, red, math text to the right of the video, timed to appear three times: between 0-15, 16-25 and 26-36 seconds into the video.
