Video Repair for Windows

Video Repair fixes MP4 and MOV videos that won't play — right on your PC, offline.

When a camera, phone, drone, dashcam or screen recorder stops suddenly (the battery dies, the card is pulled, the app crashes), the footage is usually still in the file. What is missing is the index a player needs to find it — the "moov atom". Without it, Windows shows error 0xc00d36c4, the video lasts 0:00, or nothing opens at all. Video Repair reads the file, finds every frame and writes a new index around them. Nothing is re-encoded, so picture and sound are exactly as recorded.

HOW IT WORKS

1. Add the broken video: drag it in, or press Ctrl+O.
2. Video Repair checks it and repairs it in one go. One number shows how far it has come, from the first check to your finished video — in the window's title too, so you can work in another window meanwhile.
3. If the camera's settings were lost with the index, it finds a working video from the same camera in the same folder by itself, or asks you for one.
4. Watch the whole repaired video free. Save it when you are happy with it.

WHAT IT FIXES • Recordings cut off by a flat battery, a crash or a pulled memory card • Videos that show 0:00 length, a black screen, no thumbnail, or error 0xc00d36c4 • MP4, MOV, M4V, 3GP and AVI files from phones, GoPro and other action cameras, DJI and other drones, dashcams, OBS and other screen recorders • Other formats Windows can't play (MKV, WebM, TS, MTS, WMV and more): Video Repair can make a copy that plays. That copy is converted, so it is not byte-for-byte the original, and your original is never touched.

PRIVATE BY DESIGN • Your videos never leave your computer. The repair runs offline. • Your original file is never changed. The repaired video is saved as a new file. • No account. The program counts anonymous usage (for example how many repairs finished) and never sends a file name, a path or anything from your video. You can turn this off in Settings.

GOOD TO KNOW • Video Repair fixes files that exist but won't open. It is not a deleted-file recovery tool, and it cannot bring back footage that was overwritten. • AAC sound (used by most phones and action cameras) usually comes back from the damaged file itself. Other sound, such as the PCM some cameras record, needs a working video from the same camera; without one, the picture is recovered silent. • Making a copy that plays from H.265 (HEVC), VP9 or AV1 video may need a free codec from Microsoft Store. • Windows 10 and 11, 64-bit. English and Arabic interface.

The download is Microsoft's signed installer: it installs Video Repair from Microsoft Store, which keeps it up to date.
