What djifix is
djifix is a free command-line application for repairing many corrupt videos recorded by DJI Phantom, Mavic, Spark, Inspire, and Osmo devices. It works with original recordings taken from the camera’s SD card; it is not a general-purpose repair tool and cannot process files produced by other repair software. Depending on the damage, it may produce an MP4 or H.264 file. Some H.264 results may not play in many media players or editors; the maker suggests VLC or IINA for playback and documents using ffmpeg to copy H.264 into MP4 format. Osmo recordings may be recovered without their audio track. djifix cannot restore footage that was never written into the file, including final seconds that may remain in the camera’s volatile memory. The maker also 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. A pre-built download is available for 64-bit Intel Mac OS X. The C source is released under the GNU GPL and can be compiled with a C compiler. The maker offers paid repair and conversion on request, refunding the repair fee if djifix cannot repair the file.
Who it suits
djifix suits owners of supported DJI devices who have the original recording from the camera’s SD card and can use a command-line tool. It is also an option for people who can compile C source or run the provided 64-bit Intel Mac binary.
What it does well
- Free to use.
- Supports recordings from five listed DJI device lines.
- Can produce MP4 or H.264 output.
- C source is released under the GNU GPL.
- No reference file is needed.
What to know first
- Requires the original camera SD card file.
- No pre-built Windows binary is offered.
- Osmo repairs may have no audio.
- Unwritten footage cannot be recovered.
Limits
djifix cannot recover video that was never written to the file, and Osmo repairs may omit audio. Files under 10 MBytes and files containing only zero bits or 0xFF bits are described as unsuitable for repair.
Getting started
- Open the djifix website.
- Use the original recording from the camera’s SD card.
- On a 64-bit Intel Mac, download the pre-built binary, or compile the C source with a C compiler.
- If the repair yields H.264, try VLC or IINA for playback.
- Use ffmpeg to copy some H.264 output into MP4 format.
Verdict
Choose djifix if a supported DJI recording is corrupt and you still have the original SD card file. Look elsewhere if you need general-purpose repair, a pre-built Windows application, or recovery of footage never written to the file.
