When to use

Use this skills whenever you are dealing with Remotion code to obtain the domain-specific knowledge.

New project setup

When in an empty folder or workspace with no existing Remotion project, scaffold one using:

npx create-video@latest --yes --blank --no-tailwind my-video

Replace my-video with a suitable project name.

Starting preview

Start the Remotion Studio to preview a video:

npx remotion studio

Optional: one-frame render check

You can render a single frame with the CLI to sanity-check layout, colors, or timing.
Skip it for trivial edits, pure refactors, or when you already have enough confidence from Studio or prior renders.

npx remotion still [composition-id] --scale=0.25 --frame=30

At 30 fps, --frame=30 is the one-second mark (--frame is zero-based).

Captions

When dealing with captions or subtitles, load the ./rules/subtitles.md file for more information.

Using FFmpeg

For some video operations, such as trimming videos or detecting silence, FFmpeg should be used. Load the ./rules/ffmpeg.md file for more information.

Silence detection

When needing to detect and trim silent segments from video or audio files, load the ./rules/silence-detection.md file.

Audio visualization

When needing to visualize audio (spectrum bars, waveforms, bass-reactive effects), load the ./rules/audio-visualization.md file for more information.

Sound effects

When needing to use sound effects, load the ./rules/sfx.md file for more information.
