I am getting intermittent corrupt video files using any size and class SD card. I have formatted to FAT32 and used different sizes for the 16gig they sent to 64gig. It can happen at any time. Trying to do a simple hoover or high speed maneuvers. sometime I get great video sometimes and sometimes individuals images and videos or even the whole card is lost as if it has been wiped clean. I am wondering of I am loosing connection to the cards via all the cameras leads and thus corrupting the SD card? I started to carry a laptop and check each recording to see if it is corrupt or OK. This is a slow and painful process though. Any thoughts?
