About MP4Recover

MP4Recover is an open-source web tool for attempting to repair broken MP4 video files. It combines several existing repair and processing utilities, including fix_avcC, FFmpeg, MP4Box, remoover, untrunc, and reencoding, behind a browser interface. The project's README lists a hosted version at mp4-recover.activetk.jp, and it can also be run locally.

The tool is designed to run in Docker. Setup requires Docker Engine and Docker Compose, a cloned copy of the repository, and running the build.bat script on Windows or build.sh on Linux or macOS. After the build, the interface is opened at localhost:8080, although the port depends on the docker-compose.yml file. The source does not describe which types of damage the tools can repair, and it does not describe how uploaded files are handled.
