LeClap tools (6)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • compose_video

    Render a video from an inline template descriptor (`template`). Supply user clips via userVideoPaths (absolute paths under the configured media dir) for each project_video section, optional form `fields`, and an optional `locale`. Renders in a forked worker and returns the output mp4 path plus duration/codec metadata.

  • get_template_schema

    Return the JSON Schema for a template descriptor plus a short authoring guide. Use this to understand the full set of fields when building or editing a template for compose_video.

  • ping

    Health check — returns a fixed readiness string.

  • probe_media

    Inspect a local media file (absolute path under the configured media dir) and return its duration, video/audio codecs, audio sample rate, and byte size. Probes via ffprobe directly so it never writes to stdout.

  • render_remotion_clip

    Render a composition from YOUR Remotion project to an mp4 (real motion graphics an FFmpeg filtergraph cannot express). Point it at your Remotion entry (`entry`, or a prebuilt `serveUrl`, or the configured --remotion-entry) and a `compositionId`, with optional `inputProps`. Returns the clip path; feed it to compose_video as a `project_video` clip (see sectionHint) so FFmpeg composites it in front o

  • validate_template

    Dry-run an inline `template` descriptor against the core schema WITHOUT rendering — returns instantly. Get back whether it is valid plus what compose_video will require: the project_video clip sections and the form fields. Use this to iterate on a descriptor in milliseconds before the slower compose_video render.

What the publisher says

From the LeClap repository's README, as published. We do not edit it. Read it on GitHub

LeClap

Deterministic, on-device, agent-callable video — composed by prompt or by hand.

Describe a video in one JSON template — sections, filters, music, overlays — then render that same template on a phone (React Native, on-device) or in the browser (WebAssembly). No upload, no server, no generative model: the render is deterministic and reproducible, not sampled.

Quick start · Templates · Library API · Architecture · Docs

✨ What is LeClap?

One JSON template. It renders on Node, in the browser via WebAssembly, and natively on-device on React Native — same template, same pipeline, reproducible run after run on a given platform. No upload, no server, no generative model.

🎥 Demo

Two looks at LeClap — a finished clip rendered from a single JSON template, and the mobile app composing one fully on-device.

🎬 Template-driven render one JSON template → a finished clip · unmute for sound 📱 On-device on Android the app: capture → compose → render, on the phone

🤔 Why LeClap?

Generative tools can't reproduce a result twice. Cloud renderers can't run in your user's pocket. Remotion renders without a server, but needs a browser engine to do it — LeClap links FFmpeg into the app itself.

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
