Do you have a zero-byte MDT file?

Risk of permanent loss. Immediately stop recording, eject the card and contact us!

Panasonic Lumix GH4 was announced on May 2014 and is a mirror-less Micro Four Third system camera.

This standard created by Olympus and Panasonic guarantees that virtually any lens can be used on MFT camera bodies, as long as an adapter exists.

After a new iteration of this camera, Panasonic released the GH4R in 2015, enabling the V-Log L grading and 24 fps 4K video continuous shooting.

Fix corrupted MDT on SD cards

The dreaded MDT files

Any video recording malfunction or abrupt shut down, will end up producing a MDT file.
MDT files cannot be opened, are not playing with any software.

What does MDT stand for in Panasonic lingo?
Nobody know for sure, but we have our own definition for it...

How to recover unplayable or lost GH4 clips?

MDT files or clips extracted from the card cannot be opened directly.
While video and audio data is present inside, the “brain” of the movie — indicating what this data means — is not present.

Things could be even worse if the MDT files present inside the card are 0 kb in size. In such situations, quarantining the card is mandatory.

Patrick Hall, from Fstoppers, explains both problems at length in this video:

Recover 0kb MDT clip from Lumix GH4

“I have to tip my hat to the guys over at Aero Quartet, they did an incredible job recovering this”

“If you accidentally bump the camera and you're recording, you'll definitively loose the footage you're filming.”
“Camera isn't pulling power from both batteries at the same time.”

Repair consists in reindexing the movie, this is the job of the Repair Kit.
