Key Facts
- LRF stands for Low Resolution File, created automatically by DJI devices during video recording
- LRF files are MPEG-4 format videos at 1280x720 resolution and 29fps with approximately 8000 bitrate
- The DJI Mimo app uses LRF files for the Trim Download feature, allowing preview and editing without downloading full MP4 files
- LRF files can be safely deleted after importing footage to save storage space
- You can rename LRF files to .MP4 and play them on media players like VLC or QuickTime
What Are LRF Files?
LRF files, which stand for Low Resolution Files, are compressed video proxies automatically generated by DJI drones, Osmo Action cameras, DJI Action 2, DJI Pocket 2, and Osmo Pocket 3. These files are created simultaneously with your full-resolution video recording and serve as lightweight alternatives for quick preview and editing purposes.
Technical Specifications
LRF files are encoded in MPEG-4 format with a resolution of 1280x720 pixels (720p), frame rate of 29fps, and a bitrate of approximately 8000 kbps. This compression ratio makes them significantly smaller than the original full-resolution video files, typically occupying only a fraction of the storage space while maintaining adequate quality for preview purposes.
Purpose and Function
These compressed files serve several important functions in the DJI ecosystem. The primary purpose is enabling playback and preview on your DJI controller or mobile app without requiring the full-resolution file. Additionally, the DJI Mimo app relies on LRF files for its Trim Download feature, which allows users to preview, edit, and download specific clips directly to their smartphones without transferring the entire video file.
Storage and Management
Once you've imported your footage into your computer, the LRF files become optional. Many users choose to delete these files to conserve storage space on their devices and computers. The full-resolution MP4 files contain all the video quality you need for professional editing and final output. If you ever need to use an LRF file as a standalone video, simply rename the extension from .LRF to .MP4 and it will play on any standard media player.
Compatibility
LRF files maintain excellent compatibility across devices. They can be played on virtually any media player that supports MPEG-4 files, including VLC Media Player, QuickTime, and most modern browsers. This cross-platform compatibility makes them useful for quick sharing and preview on different devices without requiring format conversion.
Related Questions
What is the difference between LRF and MP4 files from DJI drones?
LRF files are low-resolution proxies at 720p created for quick preview and editing, while MP4 files contain the full original resolution video. LRF files are much smaller and use less storage, making them ideal for mobile app editing and previewing.
Can I delete LRF files from my DJI drone storage?
Yes, you can safely delete LRF files once you've transferred your footage to a computer. They are optional preview files, and the full-resolution MP4 files contain all the quality you need for final editing and output.
Why does my DJI drone create both LRF and MP4 files?
DJI creates both files to provide efficient workflow options. The LRF files enable quick previewing and mobile editing through the Mimo app, while MP4 files preserve full quality for professional editing and final delivery.
