To recover deleted GoPro videos you have two possible outcomes, and which one you get is decided mostly by how quickly you stop writing to the card. GoPro cameras write three parallel files for every clip — the full-quality MP4, a low-bitrate .LRV preview, and a .THM thumbnail — and the small files often outlive the big one. The full MP4 is the goal. The .LRV is the fallback that keeps a clip usable when the original is partly gone.
Stop recording to the card immediately, do not format it, and do not use it for anything else until you have tried. Every additional minute of recording reuses free blocks, and the blocks a deleted clip occupies are the first ones the camera will take.
The Three Files Behind Every GoPro Clip
A GoPro clip is not one file. It is a set, and knowing which member of the set you have recovered tells you what quality to expect.
| File | What it is | Typical resolution and bitrate | Survives deletion? |
|---|---|---|---|
.MP4 | The primary recording, H.264 or HEVC | Up to 5.3K at tens of Mbps | Recoverable until its blocks are reused |
.LRV | Low-resolution preview used for camera playback and app review | Roughly 480×270, well under 1 Mbps | Often recoverable when the MP4 is not |
.THM | A small JPEG thumbnail | A few kilobytes | Usually recoverable; little value on its own |
On HERO5 and later models the three files share one four-digit clip number with different two-letter prefixes, so GH01 0001 is the video, GL01 0001 is its preview, and GS01 0001 is the thumbnail. On older bodies the primary file is GOPR0001 and additional chapters take names such as GP010001. Matching by clip number is what lets you rebuild a set after recovery, because the numbering is the only reliable link between the three.
Camera 360 footage uses a different container again, and clips from those models need a stitching step before they can be edited, which is covered in stitching 360 footage.
Why GoPro Deletion Is Usually Recoverable
Two operations on a GoPro get called “deleting”, and they are not equally destructive.
“Delete” and “Delete All” in the camera menu remove directory entries. They do not touch the video data, and because SD and microSD cards implement no TRIM command, nothing tells the card’s controller that those blocks are free to erase. The data sits in place, marked unused, until a new recording overwrites it.
“Format SD Card” in the camera menu rewrites the file system structures. It is still a quick format rather than a low-level erase, so the previous data also usually remains until it is overwritten. The distinction between the two kinds of format, and why the camera’s version is more forgiving than it sounds, is set out in in-camera versus computer formatting.
This is the counterintuitive part for most GoPro owners. The camera’s own “Delete All” feels like the most thorough option available because the footage disappears from the screen. In recovery terms it is the gentlest. The genuinely destructive operation is continuing to record, which is what most people do while deciding what to do.
Path One: Getting the Full-Quality MP4 Back
The full-quality file is worth an attempt even when the deletion was days ago, because GoPro writes video in long sequential runs that carve cleanly out of a card.
- Stop all writes. Power the camera off, remove the battery if it can be removed, and do not review footage on the camera’s screen. Playback on the device is a read, but menus that allow editing or clipping are not.
- Remove the card by its edges and set the write-protect tab to locked if the card or its adapter has one.
- Image the card before scanning it. A byte-for-byte copy becomes your working surface and the original stays untouched for a second attempt. The procedure is the same one used in cloning a card before recovery.
- Scan in deep mode. A signature scan looks for the MP4 structure itself, so it finds clips whose directory entries no longer exist. The general behavior of this scan on video files is described in camera video recovery, and the GoPro-specific pass is covered in GoPro Hero recovery.
- Sort results by clip number and size, then work out which candidates belong together as chapters.
- Save to a different drive, never back onto the card or onto the image.
On a worked example, a 64 GB card deleted in the camera and left powered off typically returns the most recent clips at full length, with older ones degrading as new recordings have reclaimed their blocks. The clips you shot yesterday are usually the ones that come back intact.
Path Two: Salvaging the .LRV Preview
When the MP4 is fragmented beyond recovery, the .LRV is often still there. It is a real video file, not a thumbnail, and it can save a take that would otherwise be a loss.
| Property | Full MP4 | .LRV preview |
|---|---|---|
| Resolution | Up to 5.3K | Roughly 480×270 |
| Bitrate | Tens of Mbps | Well under 1 Mbps, often a few hundred kbps |
| Usable for | Final delivery, grading, client work | Reference, social clips, shot logging, sync |
| Audio | Full quality | Present in most files, but verify rather than assume |
| Typical file size per minute | 100-400 MB | A few MB |
The honest assessment of what an LRV can do: it proves what was shot and when, it can be cut into an edit as an insert at small size, and it can act as a timing reference for reconstructing a damaged MP4. It cannot substitute for a 4K master, because there is no information in the file to restore. Upscaling an LRV produces a soft, blocky image, and no tool creates detail that was never recorded.
Two situations make the LRV especially valuable. When a clip was recorded over several chapters and only the middle chapter’s MP4 was overwritten, the LRV for that chapter preserves the content even though it cannot match the surrounding quality. And when the audio in a damaged MP4 is unusable, the LRV timeline frequently gives you enough of a reference to realign a separately recorded track. The dedicated workflow for these files is in recovering LRV files.
Why “Recovered but Won’t Play” Is So Common on GoPro
A recovered GoPro clip that refuses to open is usually not damaged. Three specific causes account for most of these cases, and each has a different fix.
The index was never completed. GoPro finalizes a clip’s index when recording stops cleanly. A file whose recording was interrupted by a battery pull, or whose directory entry was deleted, can exist as a complete stream of video samples with no index at the end of it. Players need that index to seek and to report a duration, so they refuse the file. The stream data is intact and only the container needs rebuilding, which is the case handled in repairing a file with a missing index.
The codec needs a decoder the player does not have. GoPro records H.264 in some modes and HEVC in others. A recovered HEVC file is perfectly valid and simply will not open in an application with no HEVC support, or on an older system without the right codec package. Test in a second player before concluding the file is corrupt.
The chapter is only a fragment. GoPro splits long recordings into roughly 4 GB chapters, so a two-hour session arrives as a series of files. A recovered chapter is a valid but incomplete clip, and some players handle a very short fragment poorly. The numbering in the file name is what tells you whether you have the whole set.
This produces the counterintuitive symptom that confuses most people: the .LRV preview plays perfectly while the full-quality MP4 will not open. The low-bitrate file is complete and indexed; the high-quality file is complete but has no index. The clip is not lost, and discarding the pair because the MP4 would not open is a common and avoidable mistake.
Rejoining Chapters After Recovery
Recovered GoPro footage almost never arrives as one file, because the camera never produced one. A long recording is a numbered set of chapters, and the job after recovery is to put the set back in order.
Match chapters by the shared clip number and the ascending chapter prefix, confirm that durations are consistent with the expected split size, and check for gaps — a missing GH02 between GH01 and GH03 means one chapter is still missing and may be worth a second scan pass. Then join the chapters in order. Most editing applications accept a sequentially numbered set and treat it as continuous footage, but the merge is cleaner if the files are concatenated without re-encoding, as described in stitching GoPro chapters. The chapter naming logic itself, including which prefixes belong to which model generation, is explained in how GoPro chapters work.
If you are on Windows and the card is still detected by a computer, a purpose-built recovery tool such as XRecovery (xappset.com) can scan SD, microSD, and other memory cards for deleted or formatted video files, including chaptered GoPro footage and the .LRV companion files. As with any recovery tool, stop writing to the card first and always save recovered files to a different drive.
Two verification steps are worth building into the workflow. Play each recovered clip end to end in two different players rather than accepting a successful open as proof, and confirm that audio is in sync at the end of a clip rather than only at the beginning. A structured pass through those checks is described in verifying recovered video files, and the format-specific case for GoPro media is in GoPro video recovery.
Frequently Asked Questions
Can deleted GoPro videos be recovered?
Yes, in most cases where recording has stopped. The camera’s Delete and Delete All commands remove directory entries and leave the video data in place, and SD and microSD cards implement no TRIM command, so nothing erases those blocks until a new recording reuses them.
What is a .LRV file, and is it worth recovering?
It is a low-resolution, low-bitrate preview that the camera writes alongside every clip for playback and review. It is worth recovering when the MP4 is gone, because it preserves the content, the timing, and usually the audio at roughly 480×270. It cannot replace a full-quality master.
Why does my recovered GoPro file not open in a player?
Usually because the clip’s index was never completed or because the player cannot decode HEVC. A file containing a complete stream of video samples but no index will not open until the container is rebuilt from a reference clip shot with the same camera, resolution, and frame rate.
How do I know if I recovered all the chapters of a long recording?
Check the chapter prefixes in the file names. GoPro splits long recordings into roughly 4 GB chapters that share one clip number, so a sequence reading 01, 03 with no 02 has a gap. Missing chapters are sometimes found by a second deep scan of the card image rather than by the first pass.
