remotion-docker-template

A dockerized Remotion starter with three example compositions, vendored Remotion skills, and an alternative Lambda deploy path.

When to use

Apply this skill whenever you are editing code in this repository. For deeper Remotion API patterns (transitions, captions, audio, etc.), defer to the vendored remotion-best-practices skill at .claude/skills/remotion/.

Compositions

ID	Resolution	Duration	Demonstrates
`HelloWorld`	1920×1080	8s (240 frames)	Atomic design pattern, frame interpolation, three-section timeline
`TransitionsDemo`	1920×1080	9s (270 frames)	`@remotion/transitions` (`TransitionSeries` with fade and slide presets)
`CaptionsDemo`	1080×1920	10s (300 frames)	`@remotion/captions` — `parseSrt` + `createTikTokStyleCaptions` flow

All compositions are registered in src/index.tsx with zod schemas for prop validation in Studio.

Atomic-design layout

src/components/
  atoms/        — primitives (AnimatedText, AnimatedCircle, ScrollingPage)
  molecules/    — composites (IntroSection, ContentSection, OutroSection, CaptionPage)
  organisms/    — full compositions (HelloWorldComposition, TransitionsDemo, CaptionsDemo)

When adding a new component, place it at the appropriate layer and follow the existing folder convention:

ComponentName/
  index.tsx
  types.ts
  README.md
  ComponentName.test.tsx

Tailwind v4

Tailwind is enabled via @remotion/tailwind-v4 in two places:

remotion.config.ts — for Studio (Config.overrideWebpackConfig((c) => enableTailwind(c)))
render.mjs — for headless renders (bundle({ ..., webpackOverride: (c) => enableTailwind(c) }))

Stylesheet entrypoint: src/index.css (single line: @import 'tailwindcss';).

Use className on container divs (see src/components/molecules/IntroSection/index.tsx as the reference migration).

Do NOT use transition-* or animate-* Tailwind classes — Remotion renders frame-by-frame and CSS transitions don't apply. Animate via useCurrentFrame() + interpolate() / spring() instead. This is enforced by .claude/skills/remotion/rules/tailwind.md.

Rendering

# Studio (live preview)
npm run dev

# Local render — set COMPOSITION_ID env to pick which one
COMPOSITION_ID=TransitionsDemo node render.mjs
COMPOSITION_ID=CaptionsDemo node render.mjs

# Docker render
COMPOSITION_ID=TransitionsDemo docker compose up remotion-render

# Lambda (alternative)
./scripts/deploy-lambda.sh TransitionsDemo
# Full guide: docs/LAMBDA_DEPLOY.md

render.mjs reads COMPOSITION_ID and dispatches to per-composition input props (TITLE/SUBTITLE for HelloWorld, SCENE_ONE_TEXT/etc. for TransitionsDemo, SRT_PATH for CaptionsDemo).

CI

GitHub Actions in .github/workflows/:

build-and-publish.yml — pushes Docker image to GHCR on main
render-video.yml — manual dispatch with composition_id (choice) + per-composition input fields
upload-to-releases.yml — attaches rendered MP4 to a GitHub release
