DJI LRF files: what they are and can you delete them?

By Adrian Sava · For Osmo Pocket 4P and 4 users

An .LRF file is a low-resolution copy of a video, saved at the same time and with the same name. The DJI Mimo app uses these copies so you can preview and trim clips on your phone without downloading the full MP4. Your full-quality video is the .MP4, and it doesn't depend on the LRF.

Can I delete DJI LRF files?

Yes, from the copy on your computer, once you no longer need to preview or trim those clips in DJI Mimo. Deleting an LRF doesn't touch the MP4 or its quality. I'd leave them alone on the card itself: some users report the camera showing an error when it plays a clip whose LRF is gone.

If you keep them, keep them together

Leave each LRF in the same folder as its MP4, with the same name. If you move your videos into folders and leave the LRF files behind, you end up with a pile of previews that no longer match anything.

Which clips get an LRF?

On my Pocket 4P card, only normal clips have an LRF. Slow-motion clips get a .AAC file instead, with their sound. My LRF files are 1280×720 and have sound.

LRF vs MP4: which one to edit

Always the MP4. LRF files are low resolution, so they're only good for previews.

When LogSortie moves or renames a clip, its LRF, AAC and SRT files go with it. More about LogSortie
