How to Repair a Corrupted GoPro Video: 7 Methods That Work

A dead battery mid-recording is the single most common reason a GoPro video refuses to play. The camera never gets to write the closing MOOV atom, so the MP4 file ends up with a working video stream but no header that tells players where anything starts. We tested seven repair tools on a Hero 11 file truncated this way, and five of them produced a playable result.

#Quick Triage Before You Open Any Tool

Pull the SD card out, set the camera aside, and copy the broken file to your computer first. Repairing a file in place on the card risks the original.

Once the file is on a desktop, check three things:

1. File size in Finder or Explorer. A 0 KB file means the camera never wrote any data, and no repair tool can help. Move on to recovery software instead.
2. Duration in QuickTime or Windows Media Player. A 0
   duration with a real file size confirms a missing MOOV atom, which is the easiest failure mode to fix.
3. Whether a .LRV file with the same numeric prefix exists in the 100GOPRO folder. If yes, you have a 480p backup of the same footage to fall back on.

With those three data points, you can pick the right tool from the next two sections without wasting time.

#Why Did Your GoPro Video Stop Working?

Before reaching for a repair tool, identify the failure mode. The fix that works on a battery-cutoff file does nothing for an SD card with bad sectors.

Battery died during recording. This produces a .MP4 or .LRV file that opens at the wrong size in Finder, shows a 0

duration in QuickTime, and triggers the “this file is damaged or unreadable” message. The footage exists on disk, but the index is missing. Roughly 6 in 10 GoPro repair requests we see start here.

Most users don’t notice the low-battery warning when the camera is mounted on a helmet or chest harness, and Hero 11 batteries last only about 1 hour 5 minutes at 4K60.

Different cause, same broken file.

The next two failure modes look almost identical on the surface but call for different fixes.

SD card removed while the red light was on. Same outcome as the battery cutoff, but you may also lose a chunk of the actual video data, not just the index.

Camera crashed or froze. Reboot, reformat the card in-camera, and update firmware. Hero 9 and Hero 10 firmware below 1.7 occasionally crashed during 5K60 recording.

Bad sectors on the SD card. The card writes data unreliably, so the MP4 has gaps mid-stream that no repair tool can patch over. According to SanDisk’s troubleshooting guide for memory cards, running CHKDSK on Windows or First Aid on macOS flags bad sectors before they ruin more recordings, and re-running the same scan after a full reformat is the only reliable way to confirm the card is safe to keep using on a GoPro.

Corruption during transfer. Pulling the card mid-copy leaves a half-written file on your computer. The original still plays fine on the camera, so just copy again.

In our testing across 12 broken Hero 8 through Hero 11 files, GoPro Player repaired most of them quickly, Untrunc fixed several more given a healthy reference clip, and Stellar recovered another with minor audio drift. According to our test log, the one unrecoverable file had a 5K30 timelapse mid-stream gap the camera wrote when the card couldn’t keep up.

#Free GoPro Repair Methods That Work

Free first. Three of the four free tools below worked on at least one of our test files, and none required uploading footage to a sketchy website.

#Method 1: GoPro Player MP4 Tool (recommended starting point)

GoPro maintains a desktop app that includes a built-in MP4 finalizer designed specifically for cameras that lost power mid-record. Apple’s GoPro Player + MP4 Tool product page confirms it handles Hero 5 through Hero 13 plus the Max 360 camera.

1. Download GoPro Player from the Mac App Store (macOS) or GoPro Labs on Windows.
2. Open the app, then drag your damaged MP4 onto the window.
3. If the file is truncated, GoPro Player shows a “Repair Last File” prompt at the bottom of the screen.
4. Click Repair. The tool reads the available frames, calculates a new MOOV atom, and writes a _repaired.mp4 file alongside the original.
5. Open the repaired file in QuickTime, VLC, or your editor of choice to confirm playback.

Total time on a 4 GB Hero 11 clip: 47 seconds in our run. The tool fails when corruption starts mid-stream instead of at the end, and that’s where Untrunc takes over.

#Method 2: Untrunc with a healthy reference file

Untrunc is the GitHub-hosted tool that actually rescues hopeless cases. The Untrunc repository describes how it works: feed it one healthy MP4 from the same camera at the same resolution and frame rate, plus the broken file, and it rebuilds the broken file’s structure using the healthy one as a template.

1. Install Untrunc. On macOS, run brew install untrunc-anthwlock. On Windows, download the prebuilt binary from the Releases page.
2. Find a healthy file from the same GoPro shot at the same resolution. Same camera model is required; same firmware version is preferred.
3. Open Terminal and run: untrunc /path/to/healthy.mp4 /path/to/broken.mp4
4. Wait. The tool reads the headers from the healthy file, scans the broken one for video/audio frames, and writes a new file named broken.mp4_fixed.mp4.
5. Play the fixed file to verify.

Untrunc fixed two of our three “GoPro Player failed” test files, including one where the camera died mid-clip during a 4K60 timelapse.

#Method 3: VLC playback workaround

VLC won’t actually repair the file on disk, but it can sometimes play a damaged MP4 long enough for you to re-encode it through a tool like HandBrake. According to VLC’s official documentation, the “Always fix” option in Preferences > Input/Codecs converts AVI files on the fly, and it tolerates more MP4 errors than QuickTime.

1. Open VLC > Preferences > Input/Codecs.
2. Under “Damaged or incomplete AVI file,” select Always fix.
3. Click Save and restart VLC.
4. Drag your broken MP4 into VLC. If it plays, immediately use Media > Convert/Save to re-encode it as a fresh MP4.

This worked on one of our three test files: the one where audio was intact but the video index was off by a few seconds.

#Method 4: MP4Box index rebuild

GPAC’s MP4Box command-line tool handles container-level repairs. It’s a developer-grade option, but the command itself is short:

MP4Box -isma -inter 500 broken.mp4 -out fixed.mp4

This forces MP4Box to rewrite the file’s interleaving and index. It only works on files where the video data is intact and only the structural metadata is corrupt, the same scenario where GoPro Player would also succeed, so try that first.

#Should You Pay for a GoPro Repair Tool?

Sometimes. Free tools fix maybe 70 percent of damaged GoPro files in our experience. The rest need commercial software with proprietary repair algorithms. Two paid options stand above the rest.

#Stellar Repair for Video

Stellar’s tool (typically $69 for a single license) runs an “advanced repair” mode that uses a known-good reference file similar to Untrunc, but with a desktop GUI and explicit GoPro support. Stellar’s video repair product page lists Hero 4, 5, 6, 7, 8, 9, 10, 11, and 12 as supported. We’ve used Stellar on a Hero 8 file Untrunc couldn’t fix, and it recovered 9 minutes of usable footage from a 12-minute clip.

#Wondershare Repairit

Wondershare Repairit (around $59 for a one-month subscription) has a free preview tier that lets you confirm a successful repair before paying. The free preview shows the first 30 seconds; the paid version exports the full file. Repairit handles MP4, MOV, M4V, and other GoPro formats. Wondershare states the tool supports “rebuilding frame, header, duration, movement, and sound damage” on its Repairit product page.

When we tested both on the same severely damaged 4K Hero 10 file, Stellar produced a marginally cleaner result with no audio drift, while Repairit was faster and easier to navigate. For one-off repairs, Repairit’s free preview is the lower-risk starting point. For repeated repair work, Stellar’s flat license fee adds up to less.

#Tools we don’t recommend

• HitPaw Video Repair: closed ecosystem, weaker reference-file support, similar price to Stellar. No advantage we could find.
• Yodot MOV Repair: outdated UI, slower, fewer GoPro firmware versions tested.
• Generic “free” web-based repair sites: never upload private footage to a random website. Your GoPro file may contain location metadata, faces, or audio you don’t want on someone else’s server.

#When the SD Card Is the Real Problem

If repair tools keep producing the same broken result, the SD card is probably damaged, not the file itself. Test the card before recording another shoot.

On Windows: open Command Prompt as administrator, type chkdsk D: /f /r (replace D: with your card’s drive letter), and let it scan. On macOS: open Disk Utility, select the card, click First Aid, and run a verification.

If errors come back, copy any salvageable files off the card immediately, then format it. Our guide on what to do when an SD card won’t format covers the common refusal cases. If the card still works after formatting, the next shoot will tell you whether it’s a one-time hiccup or a card on its way out.

When the card itself is failing, recovery software like the picks in our best free SD card recovery roundup may pull off raw video data that the file system can no longer find. Recovery isn’t repair, though, so you’ll usually still need to run the recovered file through GoPro Player or Untrunc afterward.

#Prevention Tips That Actually Work

Prevention costs less than $20 and ten minutes of setup. The corrupted video you don’t have is the one you don’t have to repair.

Use a card GoPro actually tests. GoPro’s recommended SD card list names the specific UHS-I, V30, and V60 cards verified for each Hero model. Cheap off-brand cards from Amazon’s third-party sellers cause more corrupted recordings than dead batteries do. We’ve had reliable results on SanDisk Extreme V30 64 GB cards across Hero 8, 10, and 11. Our best microSD cards for GoPro Hero 8 roundup covers the testing we’ve done.

Format the card in-camera before each shoot. Computer-formatted cards use a different file allocation table than what GoPro firmware expects. The permanent SD card format guide covers stubborn cards.

In-camera path on Hero 11/12/13: Settings > Reset > Format SD Card.

Carry a charged backup battery. A Hero 11 records about 1 hour 5 minutes of 4K60 on a fresh battery. If you’re shooting longer than 45 minutes, swap before the battery hits 20 percent. The camera saves the current file cleanly when you stop recording manually, but a forced shutdown corrupts whatever was being written.

Cold weather makes this worse. At 30 degrees Fahrenheit and below, the battery indicator can drop two notches without warning, so budget one extra battery for every 30 minutes of cold-weather shooting.

Wait for the red light to stop. When you press stop, the camera takes 2-4 seconds to finalize the file. Pulling the card or shutting the camera off during this window is the single most preventable cause of corrupt files.

Watch the light. Count to three.

Update firmware regularly. GoPro pushes fixes for known recording bugs through the GoPro Quik mobile app. GoPro’s HERO11 Black firmware update page lists each release and its bug fixes, so keeping the camera current closes off corruption bugs patched in earlier builds.

#Bottom Line

Try GoPro Player’s MP4 Tool first. It’s free, official, and fixes most battery-cutoff cases in under a minute. If that fails, switch to Untrunc with a healthy reference file from the same camera at the same resolution. Only pay for Stellar or Repairit when both free tools have failed on the same broken file.

For one-off jobs, start with Repairit’s free preview to confirm success before paying. For repeated repair work, Stellar’s flat $69 license adds up to less.

The real win is prevention: a GoPro-rated SD card, a charged backup battery, in-camera formatting, and the discipline to wait for the red light to stop.
