Minitooler Video Repair is a browser tool for diagnosing and repairing damaged videos that will not play, seek, or show the correct length. It accepts MP4, MOV, MKV, AVI, WebM, and TS files, including files that will not open. Automatic repair can rebuild an index, regenerate timestamps, discard corrupt packets, or remove a damaged audio track. It first tries to repack the video losslessly, keeping the original video and audio intact in a new container; re-encoding is a last resort. Diagnosis and repair run in the browser with ffmpeg compiled to WebAssembly, and the page says the file is not uploaded or stored. Minitooler lists crashed screen recordings, interrupted phone or camera clips, unseekable videos, and drone or dashcam footage as use cases. The free plan is listed at free and allows 3 repairs a day, with files up to 100.00 MB per file on the Video Repair page. Pro costs $5 a month and includes unlimited repairs, no file-size cap, every future tool, and priority support. No signup or email is required, and repaired results have no watermark.
