…ynthesized chiptune, brand-styled composite - mgba_runner: K (set held keys) and M (movie frame dump) commands for frame-exact footage capture - capture.ts: one 31-press choreography replayed on GBA/GB/NES in a shared 24-frames-per-press schedule, every frame dumped as PPM - music.ts: original 125 BPM A-minor chiptune/electro bed synthesized from scratch (square arps, triangle bass, noise hats, sine kick), structured to the storyboard - promo.ts: 1080p60 timeline renderer (title, live-typed component, TS-to-C split, cartridge sizes, lockstep three-console gameplay with button read-out, receipts, close) streamed raw into ffmpeg; finished with the pocketjs-video-outro brand card in X-compatible mode Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ps, logo badge, new tagline - drop the cartridge-sizes interstitial; ROM sizes now sit under each console in the gameplay segment, demo starts at 19.2 s (was 23 s) - gameplay entry stays locked to the soundtrack: lead melody moved to bar 10 = 19.2 s, breakdown/resolve retimed, bed now exactly 46.9 s - PocketJS logo badge on every frame; no appended end card - title tagline: Reactive JavaScript in 2 KB of RAM - fix rawvideo truncation: await FileSink.write/flush per frame — an unawaited backpressure Promise dropped bytes mid-frame (EPIPE) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…oolchain jargon line - the badge previously drew assets/images/logo.png (the launcher's play icon), not the brand mark; redraw the site's 32x32 lens/viewfinder SVG (rounded-rect edge, lens dot, two bars, silver gradients) in canvas vectors so it stays crisp at any size - remove the 'no JS engine on device · arm-none-eabi-gcc · sdcc · cc65' footer from the TS-vs-C split page Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

What
A fully reproducible pipeline that renders the Pocket Vapor promo video for X, end to end, from the repo itself:
How
K <mask>(set held keys) andM <n> <prefix>(run n frames, dump each as PPM). Frame-exact, deterministic.Gotcha fixed along the way: Bun
FileSink.write()returns a Promise under backpressure; not awaiting it truncates the rawvideo stream mid-frame (ffmpeg:packet size < expected frame_size, then EPIPE). Every frame write/flush is now awaited.Every number shown in the video is cross-checked against the blog post and
vapor/README.md.bun test vapor/tests: 41 pass, 7,264 expect() calls.🤖 Generated with Claude Code
