remotion-render-pipeline

What problem does it solve?

This Skill turns a ready Remotion composition into a production-ready MP4 by synthesising voiceover, rendering the video, validating technical output, and shipping it to storage, Telegram, and Linear without manual glue work.

Core Features & Use Cases

• Typecheck guardrail: runs tsc --noEmit before rendering to prevent wasted cycles and guaranteed-bad outputs.
• Voiceover synthesis and caching: generates per-scene audio MP3s via ElevenLabs (with deterministic cache keys) and gracefully falls back to on-screen text when ELEVENLABS_API_KEY is missing.
• Deterministic render with timeout + retry: executes npx tsx render/render.ts with a 600s timeout and a single retry for hangs/crashes.
• Technical validation: verifies duration tolerance, codec (h264), resolution, and file size limits before publishing.
• Multi-channel delivery: uploads the MP4 to Supabase storage using signed URLs, notifies via Telegram (inline vs link by size), and creates a routed Linear ticket for tracking/escalation.
• Artifact reporting: writes a per-job JSON summary to .research/renders/ for traceability.

Quick Start

Ask the agent to render and deliver the MP4 for a known job after remotion-composition-builder has marked the composition as ready, providing jobId, the composition id (e.g. Explainer), outputPath, and the full props plus linear routing information.
