What djifix is

djifix is a free command-line application for repairing many corrupt videos recorded by DJI Phantom, Mavic, Spark, Inspire or Osmo devices. It is intended for the original recording on the camera’s SD card, not for files produced by other repair software or general video repair. A pre-built binary is available for Mac OS X on 64-bit Intel architecture. The C source code is released under the GNU GPL and can be compiled with a C compiler; there is no pre-built Windows binary. Depending on the damage, repaired output may be MP4 or H.264. Some H.264 files may not play in many media players or editors; the site suggests VLC or IINA for playback and describes using ffmpeg to copy H.264 into MP4 format. For Osmo recordings, a repair may recover video without audio. djifix cannot restore footage that was never written to the file, including final seconds that may remain in the camera’s volatile memory. The maker says files under 10 MBytes contain only a fraction of a second of video, and files made entirely of zero bits or 0xFF bits cannot be repaired. Paid file repair and H.264-to-MP4 conversion are also offered on request; the repair fee is refunded if djifix cannot repair the file.
