# Third-Party Notices

This product includes and packages third-party software for local video editing, preview, export,
and transcription. Release owners must review the exact binaries and package contents before public
distribution.

## FFmpeg and ffprobe

The app uses FFmpeg and ffprobe as native sidecars for media diagnostics, audio extraction, proxy
generation, silence detection, and export validation.

- Project: https://ffmpeg.org/
- License: FFmpeg is distributed under LGPL 2.1+ by default, or GPL when built with GPL-only
  options. The exact obligations depend on the binary build configuration shipped with a release.
- Release check: run `pnpm --filter @aivideo/desktop release:verify-sidecars` and review the
  printed FFmpeg `configuration:` line before external distribution.
- Distribution note: keep source offer, license text, and attribution aligned with the selected
  FFmpeg binary provider before publishing a beta outside the team.

## Remotion

The app uses Remotion packages for timeline preview composition and final rendering.

- Project: https://www.remotion.dev/
- Packages used by the desktop app include `remotion`, `@remotion/player`, `@remotion/renderer`,
  `@remotion/bundler`, and `@remotion/media`.
- Release note: verify Remotion's current commercial and licensing terms before external
  distribution, especially for commercial use and packaged render workflows.

## Chrome Headless Shell

The app packages the Chrome Headless Shell version selected by Remotion for deterministic local
preview and export rendering. Chromium license and attribution files are retained beside the
packaged browser runtime.

- Chromium project: https://www.chromium.org/
- License: BSD-style license plus third-party component licenses included with the runtime.
- Release note: retain the packaged `LICENSE.headless_shell` and `ABOUT` files in every artifact.

## whisper.cpp and Whisper Model Files

The app uses a local whisper.cpp sidecar for transcription and downloads the selected Whisper model
to the user's application-data directory on demand.

- whisper.cpp project: https://github.com/ggerganov/whisper.cpp
- whisper.cpp license: MIT.
- Default model filename: `ggml-base.en.bin`.
- Model location: the app settings point to the user's transcription model folder, normally under
  the desktop app's user data directory.
- Model source: `ggerganov/whisper.cpp` on Hugging Face. The base.en file is verified against the
  release SHA-256 before use.
- Distribution note: model files are not bundled in the app package. Review the model repository's
  license and model-card terms before changing the download source or redistributing weights.

## Rspack and esbuild

Remotion's packaged bundler uses Rspack and esbuild to compile project-local React/Remotion source.
Their JavaScript packages and architecture-specific binaries are included in the application bundle.

- Rspack: https://rspack.dev/ (MIT)
- esbuild: https://esbuild.github.io/ (MIT)

## Electron

The desktop shell is built with Electron.

- Project: https://www.electronjs.org/

## React

The renderer UI is built with React.

- Project: https://react.dev/
- License: MIT.
