Video recovery guide
GoPro Battery Died While Recording? Recover Your Video
If your GoPro lost power and the last recording will not open, stop recording on that card. The next step depends on whether the video is missing, present but unplayable, or simply absent from the app. A flat battery does not prove the footage is lost, and it does not guarantee it can be recovered.
Start here: keep the original card and copy its files before attempts that can change them. If the video is visible, check its size and playback. If the camera offers file repair, follow the instructions for your model with a charged battery.
Choose the recovery path that matches your file
| What you see | What to try |
|---|---|
| Missing in the app, visible on the card | Copy the video with a card reader and try opening the copy. |
| MP4 exists and has a non-zero size, but will not play | Check camera repair, then try a compatible reference clip on a copy. |
| Video is missing from the card or has 0 bytes | Look for a backup or recover the file from the card before attempting MP4 repair. |
| Earlier chapters play, last chapter does not | Back up every chapter and investigate the final segment separately. |
1. Preserve the SD card and completed recordings
Do not format the card or make more recordings on it. On a computer, inspect the DCIM folder and copy the original files to another drive. Keep filenames and completed chapters together. A low-resolution preview is not a substitute for the original video.
If the card disconnects, reports read errors, or cannot be copied, stop repeated repair attempts. MP4 repair needs an accessible file; a storage-recovery service may be more appropriate for irreplaceable footage.
2. Check the camera's own file repair
With a charged battery and the original card, check whether your camera offers a repair prompt. Some GoPro models perform file repair automatically; older models may use an SOS prompt. Follow the instructions for your exact model and keep power stable while a repair is running.
For example, the GoPro HERO5 Session manual describes a file-repair message. That does not mean every GoPro uses the same button sequence or can repair every damaged file. Copy any repaired output and check it before reusing the card.
3. If the MP4 exists but still will not play
Try the copy in another player first. A codec compatibility problem is different from a broken recording. If the video remains unreadable, a short healthy recording from the same camera can provide a reference for a repair tool.
- Match the camera, codec, resolution, frame rate, and audio settings as closely as possible.
- Use an existing healthy clip where possible. If you need to record one, use a separate card after preserving the damaged recording.
- Try repair on copies, keeping the original untouched. See how to choose a reference file.
- Check the start, middle, end, audio, and synchronization of the output. A playable preview does not prove every frame was recovered.
Try local repair for an existing MP4
StreamSalvage for Windows can attempt repair with a reference clip. Video processing stays on your PC. Preview the result free; export costs $29 once. Compatibility and recovery depend on the recording.
Try StreamSalvage on Windows4. If the video is missing or empty
Check other copies, previous imports, and backups. If the original file cannot be found, card recovery must come before container repair. Save recovered files to a different drive. StreamSalvage repairs existing files; it is not an SD-card undelete tool.
How much footage can come back?
There is no fixed number of seconds a repair will recover. Data still in memory when power failed may never have reached the card. Damage or overwritten sectors can also remove material. Keep any playable chapters even if the final chapter cannot be repaired.
For future recordings, check battery condition, leave storage headroom, and follow your model's power and card guidance. For other GoPro errors, use the general GoPro repair guide.
Frequently asked questions
Does a GoPro delete footage when the battery dies?
Power loss can leave an unfinished or damaged recording. Completed files may still be available, but recovery depends on what reached the card and whether it remains readable. Check the card and backups before assuming the footage is gone.
How do I recover GoPro footage after the battery died mid-recording?
Stop recording on the card and back up readable files. Follow any file-repair prompt for your camera model with stable power. If an MP4 still will not play, try repair on a copy with a matching reference clip. Missing files need card recovery first.
Can I repair a 0-byte GoPro video?
A 0-byte file contains no video data for an MP4 repair tool to rebuild. Look for another copy, completed chapters, or recoverable data on the original card. Save any recovered files to another drive.
Why is the end of a recovered GoPro video missing?
Some frames may not have been written before the camera lost power, or part of the file may be damaged. A repair tool cannot recreate footage that is absent. The amount of missing material varies.
