Spectrum Reel is a Video.js 10 skin built from a scan of the film it plays. The seek bar borrows the old movie-barcode idea and makes it the timeline: not one colour per scene but every frame, eight a second, squeezed into a column and cut into scenes at the hard cuts, so you can see the aurora or the desert and jump straight there (click, [ and ], or the Scenes menu). Instead of one gradient over every frame, each row of controls gets its own backing for the picture behind it: a thin shade over a dark horizon, a paper chip over cloud or a lit city. That map is made once per video by a small script, so nothing reads the video during playback, and without it the skin falls back to a plain scrim. Footage: NASA ISS time-lapses (public domain in the US), streamed from Mux.
