A heads-up display that fills its placed box: corner brackets, a timecode that counts up from 0 to `seconds` as p goes 0 to 1, a label top right and a progress bar along the bottom. The recording-viewfinder look. Plain HTML and CSS; the timecode is rewritten by the timeline clock like motion_counter.
