Instead of Untrunc
Untrunc alternatives
Untrunc repairs damaged or truncated MPEG-4 videos by rebuilding missing or damaged index metadata from a healthy reference recorded with the same camera and settings. It supports MP4, MOV, M4V and 3GP, and reconstructs file structure without re-encoding the raw media. Repairs run offline on local files; the software is free, open source and available for Windows, macOS and Linux. Windows includes both a command-line tool and a graphical interface, while other platforms use a command-line workflow.

Its reference-video requirement is central: Untrunc cannot recover empty files, corrupted raw video data, or containers such as AVI and MKV. Readers may prefer another product for a different file type, a browser-based workflow, or repair without a matching reference. Compare the formats and recovery method each alternative supports, along with its platform, price and privacy approach. Some alternatives repair documents or archives rather than video, while online services may require uploading media. A broader repair scope or easier workflow may suit a different problem, but it does not make every option a substitute for Untrunc's local MPEG-4 repair.
