Notes and caveats
- Full-screen, sound-on video in X's Immersive Media Viewer (the Video tab, or a video opened full screen and swiped up). A call-to-action button appears after one second. Recommended: captions for spoken audio; the most important visual at the three-second mark.
- Read from the page's diagram labels as pixels of a 1080 x 1920 frame: 155px at the top and 300px at the bottom (the two full-width lines). The diagram isn't drawn to scale (only the top band matches a 1080 x 1920 frame), and it also marks 245px, 205px and 155px on the elements at the bottom (progress bar, buttons, label), not drawn here. The overlays show for the first two seconds only (decision D42).
