Black Box: a flight recorder for AI phone calls.
AI receptionists take thousands of calls, and every one deserves a black box. Black Box is a Video.js v10 skin for reviewing call recordings, styled as a hi-vis flight recorder. The seek bar is the tape: a two-lane waveform with the AI agent above the line and the caller below, so you can see who spoke before you press play. Hover anywhere to read that line. Flags mark the moments that matter (connected, booked, objection, closed), and the level meters, REC lamp, captions and transcript all run off real player state. It is keyboard-first, readable over bright and dark footage (try the test bench above the player), works from 360px up, and calms down under reduced motion.
A flight recorder for AI calls is a smart, real use case. The two-lane waveform makes total sense.
a flight recorder for ai phone calls is such a clever use case, black box feels like a real product

Kerf is a Video.js 10 skin built on one idea: cut the picture instead of covering it.
Most players float their controls over the video, then fight the footage for contrast with gradients and blur. Kerf cuts a notch into the player’s own frame and puts the controls there, on a solid surface in your product’s colour. They read the same over a white sky or a black night. Previews, menus and volume rise out of that frame from the control that opened them, and sink back when the film plays.
It’s built for modern SaaS and minimal products: one accent and one radius to set, plus light, dark or auto surfaces. It folds the controls away before the first play, and adds chapters, storyboard previews and captions as a notch. Every control works by keyboard, focus rings are visible, it honours reduced motion and forced colours, and it supports right-to-left layouts. axe-core reports 0 violations.

Cutting the picture instead of covering it is a really strong idea.
Tapedeck TD-90 is a cassette deck that plays video. The seek bar is the tape: it runs through a smoked window between two reels, and as the film plays the tape winds from one reel to the other.
The reels aren’t decoration. Grab one and turn it to scrub, clockwise to wind forward. They spin twice as fast at 2× and slow down at 0.5×. Ticks along the tape mark every tenth, matching the 0–9 keys.
The deck works like real hardware. Play, captions and fullscreen are piano keys that latch down when on, with an LED. Time reads off counter drums. CUE drops a marker on the tape; press it again to wind back to it. Each chapter shows up as a track on the cassette label. Volume is a VU meter, settings is a ruled spec sheet, and tooltips are embossed label-maker tape.
Every control sits on a solid surface, so it stays readable over bright or dark footage. Keys are 44px on touch, focus is always visible, and with reduced motion the reels stop and nothing slides. It comes as a cream deck or a black deck, and you can recolour the tape live.

In the wild: it’s the player for the project film on my portfolio, robiulhasan.dev
Film: “Boing Studio, a walkthrough”, a screen recording of a site I designed and built, streamed from Mux.
Using the tape as the timeline is so good.
Who wants to come to a picnic with an outdoor movie? I'll bring the video player 🧺🎬
Picnic Cinema is my new Video.js skin: a 3D garden cinema where the controls hang as tags from festoon bulbs. The lights glow when you pause and dim when the film starts.
Too comfy to reach the bulbs? Grab the remote on the picnic table.
You can still use the keyboard like a normal player: Space to play, arrows to seek and change the volume, F for fullscreen.
this is such a fun concept!
