How to organize GoPro videos: chapters, LRV files and 800 clips

An action camera produces more files per hour than anything else in your bag, and every one of them is named by a scheme that was designed for a memory card, not for a human being. A weekend of riding, diving or skiing lands on your drive as 400 files called GX010042.MP4, and the only way to know what is in any of them is to open it.

Here is what those names mean, what you can throw away, and how to get from a card dump to a library you can actually search.

Decoding the filename

GoPro filenames carry three pieces of information, packed into eight characters:

GX 01 0042 .MP4
│  │  │
│  │  └── file number: which take
│  └───── chapter number: which segment of that take
└──────── codec and generation

The prefix tells you the encoding:

Prefix	Meaning
GOPR	Older AVC single file
GP + number	Older AVC chapter, e.g. GP010042.MP4
GH	HEVC on HERO6 and HERO7
GX	HEVC on HERO8 and newer
.360	MAX and 360 cameras, a dual fisheye container

The important part is the middle. GX010042 and GX020042 are the same take. The camera splits a recording into segments, historically at the 4 GB file size limit, and continues counting chapters. If you sort a folder alphabetically, chapters of the same take sit next to each other, which is convenient. If you delete “duplicates” because the last four digits repeat, you have just cut a hole in the middle of a shot.

The files you can delete

A GoPro card contains more than clips:

• .LRV Low Resolution Video. A proxy copy the camera writes so its app can preview without transferring gigabytes. Safe to delete. Some editors keep them, rename the extension to .MP4, and use them as review proxies. That works and costs nothing.
• .THM Thumbnail, one JPEG per clip, for the camera’s own playback. Delete.
• .WAV On some models, a separate raw audio track. Keep it if you recorded with an external mic setup, otherwise it is redundant.
• .JPG bursts and timelapse sequences. These are not clips and should not be mixed in with them. Give them their own folder before anything else touches the shoot, or you will be scrolling past 900 stills to find a video.

What you should not delete: the telemetry is inside the MP4 itself, not in a sidecar. GPS track, accelerometer, gyro and speed live in a GPMF data stream in the file. If you ever want a speed overlay or a map, it is in there, and re-encoding without care strips it.

Copy first, organize second

The order that keeps you out of trouble is the same as for any camera, and worth repeating because action cameras tempt you to skip it:

1. Copy the whole DCIM folder to your working drive. Do not cherry pick on the card.
2. Verify the copy completed. Count the files.
3. Back up before you delete anything, including LRV and THM files.
4. Only then start sorting.

Action camera cards get formatted quickly and often, usually while standing in a car park with cold hands. That is exactly the situation in which the only copy of the good run gets erased.

Grouping by session, not by day

Here is where action footage differs from an interview shoot. You did not shoot scenes, you shot sessions: a morning run, an afternoon dive, a helmet cam and a chest cam of the same thing.

A structure that reflects that:

2026-08-14_Chamonix/
  01_Helmet/
  02_Chest/
  03_Drone/
  04_Stills/
  05_Selects/

Two habits make this work:

Split by mount, not just by camera. Helmet, chest, bike, handheld. When you cut, you cut between angles of the same moment, so having them separated is what makes multicam assembly quick.

Create 05_Selects on the first pass and use it. Action shooting has a terrible signal to noise ratio, often 20 usable seconds in a 12 minute clip. A selects folder, filled while you are still interested in the footage, is worth more than any tag system.

Making 800 unnamed clips findable

The core problem stays: GX010042.MP4 says nothing. You have three options.

Scrub. Free, and it costs you an evening per shoot. Most people do this once and then never revisit the archive.

Log by hand. Open each clip, type a description. Ten to fifteen seconds per clip if you are fast, so around two hours for 500 clips. Nobody sustains this.

Generate descriptions. A vision model looks at frames from each clip and produces a description, subject tags and a motion classification. For action footage this works well, because what you want to search for is exactly what is visible: snow, road, underwater, drone shot, crowd, close up on the bike. See searching video by objects for what this looks like in practice.

Whichever route you take, write the result into the filename and into Finder tags rather than into a separate app’s database. Filenames and tags travel with the files, onto the archive drive and to whoever edits next. Where footage metadata should live is the longer argument.

A renamed action clip looks like this:

GX010042_Chamonix-Ridge-Descent-Helmet_16x9_4K_60FPS.mp4

Original number first so you can always trace back, description second, technical facts last.

The audio nobody organizes

If you record ambience, an interview at the trailhead or wind noise for the sound design, those recordings usually end up in a folder called Audio and are never opened again, because a WAV file has no thumbnail and no preview.

The fix is the same as for video: describe and transcribe. A recorded voice becomes searchable text, and ambience gets classified by type, so a file called ZOOM0003.WAV becomes Chamonix-Wind-Ridge-Ambience.wav. There is a whole article on organizing audio recordings, because sound libraries rot faster than video libraries and nobody notices until they need one specific sound.

Doing it automatically

Cliptag handles the whole pass on macOS: drop the copied card folder in, it analyzes every clip’s frames and audio, writes a descriptive filename, applies Finder tags, files everything by media type and date, and transcribes anything spoken. Stills and audio in the same drop are handled as their own media types rather than being ignored.

Two GoPro-specific notes:

• Chapters are separate files to the file system, so they are analyzed separately. Chapter two of a take often gets a slightly different description than chapter one, which is honest: they are different parts of the shot.
• .360 files from a MAX are not a standard video container and are not supported. Export a flat version first.

The on-device mode on Apple Silicon is free and unlimited, which matters when a single trip produces 800 files. Cloud analysis is more precise on specific subjects and is priced per clip, with 25 free per month.
