Stellar Repair for Video vs Untrunc

Stellar Repair for Video repairs damaged or inaccessible recordings from cameras, phones, and other video devices. It works with files on memory cards, USB drives, SSDs, HDDs, and CF cards, and supports formats including MP4, MOV, AVI, MKV, MTS, and WebM, among others. It addresses issues such as blurry, grainy, frozen, flickering, stuttering, or out-of-sync playback. For severe corruption, Advanced Repair uses a working sample file made with the same device and video format. The software can process unlimited files in one batch and lets users preview repairs before saving them. It is listed for Windows, macOS, and web browsers, but it is not for mobile devices; phone and tablet recordings need to be transferred to a Windows or Mac computer. The free download previews repaired files only up to 20% of their total size. Standard costs $49.99, paid once, Professional costs $59.99, paid once, and Premium costs $69.99, paid once; each edition is listed with a Single System license.

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.
