| Intended users | The site names action-camera users, drone pilots, dashcam owners, screen recorders, security-camera operators, and videographers as users. | The maker describes use in both private and business contexts, including repairing camera and smartphone videos. |
| Privacy | The site says repairs run offline on local files, with no video uploads or telemetry. | The license says the software anonymously collects technical camera data, such as codec name and frame resolution, and that video data or information about video contents is not shared with Grau GmbH. |
| Purpose | Untrunc repairs corrupted or truncated MPEG-4 video files by using a healthy reference video to reconstruct missing or damaged index metadata. | Video Repair Tool repairs broken or damaged video files that do not play in a media player. |
| Repair method | It rebuilds the file structure without re-encoding or modifying the raw media data. | It scans for video and audio stream data and can reconstruct those streams without relying on a valid container format. |
| Support | The site directs users to the anthwlock GitHub Issues page for technical support and says the informational website does not provide software support. | The maker asks customers to submit a playable camera sample to check support and says adding support for a camera may take some weeks. |

In their own words
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.
