What it is
djifix is a free command-line utility for repairing many corrupt video files recorded by DJI Phantom, Mavic, Spark, Inspire, or Osmo devices. It requires the original recording from the camera’s SD card and is not general-purpose repair software. A pre-built binary is available for Mac OS X on 64-bit Intel architecture, while the C source is released under the GNU GPL for compilation with a C compiler. Depending on the corruption, output may be MP4 or H.264. Some H.264 results may not play in many media players or editors; the site points to VLC or IINA for playback and ffmpeg for conversion to MP4. Osmo repairs may recover video without audio. djifix cannot restore footage never written to the file, including final seconds held in volatile memory. Files under 10 MBytes contain only a fraction of a second, and all-zero or all-0xFF files cannot be repaired.
For and against
For

- GNU GPL C source is available
- May produce MP4 or H.264 output

Against
- No pre-built Windows binary

- Osmo repairs may lose audio
- Cannot recover unwritten footage
The verdict
djifix is a narrowly targeted option for damaged DJI recordings, with Mac binaries and open C source. Its file requirements, platform limits, and possible H.264 or audio issues should be considered before use.
Who it suits
It is for Mac users recovering original DJI camera recordings from an SD card. It may also help users comfortable with command-line tools and possible H.264 conversion.
