Grau GmbH is a German software company known for its expertise in data recovery and video processing. Their Video Repair Tool is a standalone utility designed specifically to repair corrupted, broken, and unplayable video files.
Developed by a German-based software house, the Video Repair Tool (VRT) is a specialized utility that focuses on reconstructing the raw video and audio streams of damaged files. Unlike standard media players, it doesn't rely on the "container" (like .MP4 or .MOV) being intact. Instead, it scans for raw data chunks and builds a new, playable file from scratch. Format Support: Repairs MOV, MP4, 3GP, and M4V files. grau gmbh video repair tool free download
