I have a Nextbase 512GW for about a month now. I have noticed that several times on a journey, the recordings will be short, like 24 seconds, 40 seconds, 1.40 mins etc etc. On a motorway journey today, of about 27 videos shot, 9 of them were short and not the 5 mins I set. Even more of a concern, I checked continuity between these curtailed videos. After every shorter video I noticed I am losing anything from 10seconds to 50 seconds of footage, which is totally unacceptable and negates the purpose of having the camera in the first place. When I noticed this happening a few weeks ago, I turned off the G sensor completely, along with the Parking sensor, so its not them. It is definitely not the SD card either. I am well versed in these cards, and have read up at length on good and bad cards, as I have quite a collection for a range of 4K GoPros, and a 4K DJI Mavic drone that need the very best cards. I have a range of Toshiba Exceria, Lexar 633X, Sandisk Extreme, and Samsung Evo cards, at 64GB which are among the best available. What could be causing this before I bring this back for a refund?
