MP4 repair and OBS recovery guides
Practical, no-fluff guides for recovering corrupted recordings — why MP4 files break after a crash, how to repair them locally, and how to stop it from happening again.
OBS and screen recordings
Start here if a desktop recording was interrupted, will not remux, or needs a safer recording format.
How to fix a corrupted OBS recording
Recover an unfinished OBS MP4 and check a recording that may be incomplete after remuxing.
Screen recording corrupted? The 4 GB trap
FAT32's 4 GB limit, crashed recorder apps, Bandicam audio problems — causes and repairs.
Repair an MP4 after a PC crash
What to do first when a crash, power loss, or forced shutdown leaves an MP4 unplayable.
OBS MKV vs MP4 recording settings
Compare MKV, standard MP4, fragmented MP4, and Hybrid MP4 for recording and editing.
GoPro, phone, and camera recordings
Find a saved copy first, then choose the recovery steps for your device and file type.
GoPro battery died? Recover the footage
Preserve the SD card, check camera repair, and distinguish a missing file from a damaged MP4.
Phone died while recording? Fix the video
Check saved videos, backups, and incomplete transfers before trying local MP4 repair.
GoPro video corrupted? How to repair it
SOS repair first, then local reference-file repair when the camera can't fix its own file.
Camera died while recording (Sony, Canon, Panasonic)
The 21 GB file that won't open usually still holds every frame. In-camera repair first, then PC rebuild.
Drone video corrupted after a crash?
The footage usually survives the impact even when the drone doesn't. DJI and others.
Dashcam video corrupted? Recover accident footage
Why the crash clip specifically breaks, 0 KB files, and repairing copies while preserving evidence.
Canon .DAT file recovery
The file a crashed Canon leaves behind is your footage without a container. How to get it back.
.MDT file recovery after camera power loss
The unfinalized file Panasonic and similar cameras leave behind — and how to get the footage out.
Video errors and playback problems
Use the exact error and the original file to distinguish transfer, codec, and container problems.
FFmpeg "invalid data found when processing input"
Check the input, inspect streams with ffprobe, and learn when remuxing can help.

Why the error happens and how to rebuild the missing index and recover your video.

Codec problem or real corruption? The one-minute VLC test, and how to fix both.
Error 0xc00d5212: "missing codec"
Usually a missing HEVC codec — but on interrupted recordings it's real corruption. How to tell.
Error 0xc10100be: "this file isn't playable"
Why Windows can't parse the container, the extension-mismatch trap, and the repair path.
Error 0xc00d36e5: "item is unplayable"
Almost always a truncated transfer. Check the original first, then repair the copy locally.
