Darkroom, a Video.js v10 skin that develops your video like 35 mm film.

Darkroom turns the Video.js v10 player into a roll of 35 mm film. The scrubber is the strip itself: four perforations to a frame, chapters spliced on frame lines, and every frame you have watched develops into an orange negative printed from the video's own storyboard. Hover a frame and it flips to a positive, with a contact print above it naming the frame and time. The readout is a darkroom timer instead of a timestamp: a camera counter that starts at S, ticks through 36 exposures and ends at 36 END, where a Roll complete card rewinds the strip in steps.

Safelight red is kept for focus rings, the exposure lamp and active states. Everything else is paper on a grain textured panel that holds 11:1 contrast over white footage, so the controls stay readable over any video. The icons are a custom family drawn for the concept: a viewfinder for fullscreen, an aperture for settings, a rewind crank for restart.

It is fully keyboard operable with visible focus everywhere, 44 px touch targets, reduced motion support, forced colors support, and a responsive layout tested from 240 px to fullscreen in Chrome, Safari and Firefox. The showcase page lets you switch between dark and bright footage and between 16:9 and 9:16.

That film-strip scrubber is clever.

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.
