a tool for the repairing of prematurely terminated .m4a files that are missing their moov atom
Drag-and-drop video file integrity checker for production workflows. Catches corrupted containers, missing moov atoms, and broken recordings that transfer verification tools like Offshoot and Hedge won't flag. Windows + macOS.
Explains why an MP4 or MOV scrubs badly, uploads slowly or will not play until fully downloaded. Reads the container layout directly: where the moov index sits relative to the mdat, how well audio and video are interleaved, wasted free padding, edit lists that shift the start, and recordings OBS never finalised. Zero dependencies, read-only.
Repair corrupt or truncated MP4 and MOV video on macOS. Rebuilds the missing moov atom so GoPro and camera footage plays again.
Homebrew tap for Cinesalve, which rebuilds the index of truncated MP4 and MOV recordings
