Untrunc
Untrunc repairs corrupted or truncated MPEG-4 video files by using a healthy reference clip to rebuild missing or damaged index metadata. It supports MP4, MOV, M4V, and 3GP containers, and leaves raw media data unmodified rather than re-encoding it. The reference must come from the same camera and use the same recording settings as the damaged file. Repairs run offline on local files, with no video uploads or telemetry. There is no file-size limit; streaming mode can handle files larger than available RAM. Windows downloads include a graphical interface and a command-line tool, while other platforms have a command-line workflow. The site describes support for GoPro footage and Sony XAVC, with the anthwlock fork adding compatibility and performance improvements. Optional stretch mode can adjust audio duration to match recovered video. Untrunc is free for personal and commercial use under GPL-2.0. It cannot repair empty files, corrupted raw video data, or non-MPEG-4 containers such as AVI and MKV.
