Again, my files were not caused by a memory card corruption but rather a loss of power from the camera itself. Now keep in mind that the GH5 camera is not an AVCCAM camera but since this link showed up multiple times on forums about GH4/5 corruption, I figured it would be worth noting it here and testing it out. Panasonic's website claims that this software can help restore footage that has been accidentally deleted from an SD memory card. A few message boards pointed to some software called Panasonic AVCCAM Restorer and AVCCAM SD Card File Recovery (located under the Software tab).
I searched through their website and tried to find a OEM software solution for these corrupt files but that path lead no where. Let's see what Panasonic offers in terms of data recovery. Unfortunately very few of the forums I found offered any helpful advice on how to recover these files, but after reading dozens of threads, I have come up with two of the best solutions if you find yourself in the sticky situation of having lost footage. Upon investigating if these files could be recovered, I found that many Panasonic users have experienced corrupt files in one form or another, and the problem dates back to the older GH4 as well. They have all been related to abrupt power loss, and all of those power losses have been related to a loose connection between the camera and the battery grip or a premature ejection of the battery inside the grip. We actually have lost about three files total in the first 60 days we have owned the new cameras. This file corruption wasn't the first time we experienced a lost file on the new Panasonic GH5 system. This process of hotswapping batteries was never a problem with any of our Nikon cameras ( Canon grips unfortunately place both batteries in the grip tray so hotswapping isn't an option at all), and as you can imagine, I was horrified to find out the hard way that the Panasonic GH5 cameras are not capable of saving files to the memory card if the grip battery is removed before power is transferred to the internal camera battery. Recently while filming our video on How to Build The Best PC for Photo and Video Editing, I accidentally corrupted a long, one hour take by trying to hotswap a dying battery in one of our GH5 cameras. I consider myself pretty experienced with electronics, computers, and cameras but by no means do I understand all the ins and outs of how data is recorded to camera buffers and transferred to flash memory cards. Let me first give a disclaimer that I am in no was a specialist in data recovery.
