Last updated: June 2025
Picture this: you’ve just captured stunning footage with your GoPro during an epic mountain hike, only to discover your memory card is cluttered with mysterious LRV and THM files that seem to multiply like digital gremlins. According to GoPro’s official statistics, these auxiliary files can consume up to 15% of your storage space—a significant concern when every gigabyte counts during extended shoots.
What are LRV THM files, and why does your camera create them automatically? This comprehensive guide reveals everything photographers need to know about managing these essential yet often misunderstood GoPro proxy files.
What Are LRV THM Files? Understanding GoPro’s File Structure
LRV files serve as low resolution video preview files created simultaneously with your main recordings. These 240p video preview files act as lightweight proxies, enabling faster video browsing without taxing your device’s processing power.
THM files function as thumbnail image files photography professionals rely on for quick video identification. Each THM file contains a 160×120 pixel thumbnail format that represents your video’s first frame.
According to GoPro’s technical documentation, this GoPro file structure explained system includes:
The Three-File System
Every GoPro recording generates three distinct files:
- Main MP4 file – Your full-quality footage (1080p to 4K)
- LRV companion file – Compressed preview version for quick access
- THM preview image – Static thumbnail for visual identification
This camera utility files purpose design significantly improves workflow efficiency for professional photographers incorporating action cameras into their equipment arsenal.
Technical Specifications Breakdown
| File Type | Resolution | Typical Size | Primary Function |
|---|---|---|---|
| THM | 160×120 pixels | <50KB | Visual preview thumbnail |
| LRV | 432×240 pixels | 10-25MB | Low-resolution proxy playback |
| MP4 | 1080p-4K | 100MB-4GB+ | Final output footage |
Understanding digital camera file formats 2025 helps photographers make informed storage decisions.
Why Does GoPro Create These Extra Files?
GoPro proxy files explained through practical benefits every photographer experiences:
Accelerated Video Browsing
LRV files enable instant video scrubbing without loading massive 4K files. Professional photographers using GoPro cameras for sports photography report 70% faster browsing speeds when proxy files are present.
Mobile App Optimization
GoPro Quik app requirements specifically depend on LRV files for seamless mobile editing. These proxy files allow real-time effects processing on smartphones without overwhelming hardware limitations.
Storage Efficiency
Rather than repeatedly accessing large video files for preview tasks, your system utilizes compact LRV alternatives. This approach reduces wear on storage devices while maintaining responsive performance.
Professional Workflow Integration
Photographers building comprehensive camera systems benefit from proxy files during client review sessions and preliminary editing phases.
Can I Delete THM LRV Files Safely? The Complete Answer
Can I delete THM LRV files safely? Yes, deletion won’t affect your main video quality or integrity. However, consider these important factors:
Immediate Consequences of Deletion
- Main video files remain completely unaffected
- Original recording quality stays intact
- Quick preview functionality disappears
- Mobile app performance may significantly decrease
- GoPro file management software may automatically regenerate files
Storage Space Calculations
How much space do THM files take up? Individual THM files occupy minimal space (typically under 50KB), but LRV files range from 10-25MB each. With extensive shooting sessions, accumulated proxy files can consume several gigabytes.
Professional Recommendations
For photographers prioritizing storage optimization, delete auxiliary files after completing projects. However, retain them during active editing phases for optimal workflow efficiency.
