Remotion Markup: A Skill for Programmatic Video Animation

Where this fits

You're building a video-generation agent that outputs Remotion compositions. The agent writes React markup, but you keep seeing animations that don't play—CSS transitions silently fail in Remotion's renderer, and the agent doesn't know the difference. The remotion-markup skill gives your agent the exact rules for driving animations with useCurrentFrame() and interpolate(), so the generated code actually renders as video.

Why agents benefit

• Avoids silent render failures: The skill explicitly tells agents that CSS transition, animation, and Tailwind animation classes won't work, forcing them to use Remotion's frame-based API.
• Preserves user edits: It instructs agents to detect and respect code changes made outside the conversation, preventing destructive overwrites during iterative editing.
• Guides timing curves: Agents learn to use Easing.bezier() and Easing.spring() for precise animation control instead of guessing with arbitrary values.
• Promotes structured markup: The skill points to interactivity best practices, encouraging agents to wrap elements in Interactive.Div with descriptive names for better debugging and future interaction support.
• Reduces back-and-forth: By embedding these rules into the agent's context, you cut down on repeated corrections and re-renders during development.

Practical scenarios

Building a product promo video

An agent assembles a 10-second promo with a title fade-in and logo scale-up. Without the skill, it might use transition: opacity 2s—which renders as a static frame. With the skill, it writes opacity: interpolate(frame, [0, 30], [0, 1]) and the animation works on the first render.

Refactoring an existing composition

Your human developer manually edits a component to add a spring effect. The agent, following the skill's "preserve user changes" rule, notices the new Easing.spring() call and doesn't overwrite it when adding a new animated element.

Multi-scene sequence with custom easing

An agent builds a slideshow with staggered text reveals. It uses Easing.bezier(0.22, 1, 0.36, 1) for a smooth ease-out, and each scene's markup follows the same structure, making the whole composition consistent and maintainable.

Add it to your agent workflow

Install the skill directly into your agent's skill directory using the CLI:

npx skills add remotion-dev/claude-code-plugin --skill remotion-markup

Once installed, the agent will automatically load the guidance when it detects Remotion-related tasks. For example, when you ask it to "add a fade-in to the title," it will produce:

import { useCurrentFrame, interpolate } from "remotion";

const frame = useCurrentFrame();
const opacity = interpolate(frame, [0, 30], [0, 1]);

You can also explore the skill's details on the OpenAgentSkill page to see its metadata and community usage.

Compare before adopting

Before adding this skill, compare it against alternatives like generic React animation guides or Remotion's own docs. Check three things: quality signals (does it reference official APIs correctly?), maintenance freshness (the version 4.0.516 suggests active updates), and workflow fit (does it complement your agent's existing skills for video generation?). Also consider whether your agent already has a similar skill that could conflict—this one explicitly redirects to a broader best-practices skill when markup isn't the core task.

Why it is worth tracking

The skill comes from the official Remotion team (remotion-dev), which is a strong quality signal—it's maintained in lockstep with the Remotion library itself. With only 13 stars, it's early, but the low star count also means less noise and a focused scope. Track it if you're building any agent that generates video content; as Remotion's API evolves, this skill will likely update to match, making it a reliable reference for your agent's animation code.
