Repair a corrupted GoPro video
GoPro cameras write the last clip’s index when you stop recording. If the battery dies, the camera freezes or the card is pulled out first, the MP4 stays on the card but won’t play. Here is what to try, in the right order.
Step 1: let the camera try its own repair
Before moving or deleting anything on the card, put it back into the same GoPro and switch it on. Many GoPro models detect a clip that was not closed properly and offer to repair it, showing a repair or SOS icon. Let the camera finish and don’t remove the battery while it works. If the clip plays afterwards, you are done.
Step 2: copy everything from the card
If the camera can’t repair the clip, or says the file cannot be repaired, copy the whole card to a computer with a card reader. Keep the damaged MP4 exactly as it is, and stop recording onto that card until you have a copy.
Know what you are looking at:
- GX…MP4 files are HEVC (H.265); GH…MP4 files are H.264. Older models use names starting with GOPR and GP.
- Long recordings are split into chapters: GX01xxxx, GX02xxxx… Only the last chapter is normally affected by an interruption.
- .LRV files are low-resolution previews and .THM files are thumbnails. Keep them, but the MP4 is what needs repair.
Step 3: record a matching reference clip
A short healthy clip recorded on the same GoPro with the same settings helps the repair a lot: same resolution, frame rate, lens or field of view, HyperSmooth setting, bit rate and codec (HEVC or H.264). Ten to twenty seconds is enough.
Why GoPro files need a careful repair
Besides video and audio, GoPro MP4 files carry extra tracks such as timecode and GPS or sensor telemetry. When the index is missing, a repair has to separate these tracks from the picture and sound inside the file. A reference from the same camera and mode shows exactly how that camera interleaves them.
How FrameRescue handles GoPro files
Upload the damaged MP4 and, if you have it, the reference clip. FrameRescue analyzes the file, rebuilds the index around the surviving video and audio, and checks the result before offering it. You pay €5.00 only if a repaired file is ready.
No repair tool can guarantee every GoPro mode. Footage that was never written to the card, or was overwritten later, cannot be rebuilt.
GoPro repair questions
What does “file cannot be repaired” mean on a GoPro?
The camera’s built-in repair could not rebuild the clip. That does not always mean the footage is gone: copy the file from the card to a computer and try a structural repair with a healthy clip from the same camera and settings.
Why is my GoPro video split into several files?
GoPro cameras split long recordings into chapters of about 4 GB, such as GX010123.MP4, GX020123.MP4 and so on. Usually only the last chapter is damaged after an interruption; the earlier ones play normally.
Should I format the card after a corrupted GoPro file?
Only after you have copied every file you need, including the damaged one. Then format the card in the camera before recording again.
Can the .LRV file help?
The .LRV file is GoPro’s low-resolution preview copy. If it plays, keep it as a fallback, but it is not a substitute for repairing the full-resolution MP4.
