Case study
ReaCut: video-editor reconstruction
An independent video editor whose authors document REA-assisted investigation of Jianying/CapCut behavior and project formats. The public implementation includes a local timeline, FFmpeg export and an experimental, lossy draft importer.
Requirements and limitations
- The v0.5.0 preview reports macOS Apple Silicon testing; Windows/Linux builds still need device validation. The macOS package is ad-hoc signed and not notarized.
- The experimental importer is documented against controlled Jianying 11.0.12922 drafts. Basic conversions are lossy: effects, keyframes and styles can be lost, and projects cannot be written back.
- REA supports the reported research workflow but is not a runtime dependency. The project uses its own code and format; MIT source and bundled third-party components retain separate licenses.
