If your GoPro is creating multiple files per video, the additional files could serve different purposes. Here’s a breakdown of common extra files you might see:
1. MP4 Files (GXO####.MP4) – The Main Video
- Your video is likely split into multiple parts due to file size limitations, especially in high-resolution formats (4K/5K, high bitrate, or long recordings).
- You need to merge them in editing software to get the full video.
2. LRV Files (GXO####.LRV) – Low-Resolution Preview
- These are Low-Resolution Video (LRV) files used for faster playback on your GoPro app.
- If you're browsing on your GoPro or editing in the app, it uses these for smooth performance.
- Not needed if you're transferring full-quality files.
3. THM Files (GXO####.THM) – Thumbnail Images
- These are tiny thumbnail images used to display previews on your GoPro or app.
- Not part of the actual video.
4. WAV Files (Audio Separates in Some Modes)
- If enabled, GoPro might save separate audio tracks (for example, RAW audio in some Protune settings).
What You Can Do:
- Keep the MP4s (merge them if necessary).
- Ignore or delete LRV and THM files unless using the GoPro app.
- Check WAV files if you need separate audio tracks.
