cdn-sip

Static asset CDN for the SIP Protocol ecosystem — served at cdn.sip-protocol.org via Vercel.

Contents

• tokens/ — token logos (consumed by sip-mobile src/data/tokens.ts)
• videos/ — demo + showcase videos (consumed by sip-app and sip-website)

Notes

• Showcase videos were re-encoded H.264 CRF 24, constant 30 fps, +faststart — visually identical to the source recordings at ~85% smaller (539 MB → ~83 MB). Originals were exported at a wasteful 5–26 Mbps; re-encoding reclaimed the waste with no perceptible quality loss.
• CORS (Access-Control-Allow-Origin: *) and cache headers are configured in vercel.json.
• Hosted on Vercel (project sip-cdn, scope rectors-projects). Pushing to main auto-deploys.
• Migrated off VPS reclabs3 (nginx /home/sip/cdn) on 2026-06-01.
