Hello, I bought a GH4 one month ago and I'm now starting to use it everyday. The problem is that most of the times I'm recording I cannot stop the recording by pressing the record button or any other button. The only way to stop it is to turn the camera off and even after I turn the button to "OFF" the camera keeps recording for like 8 seconds and then it turns off. It seems that the videos don't get affected and it seems they stop when I press to stop. So let's say I was recording and I pressed stop at 10 seconds of video, although the camera says its still recording until like 30 seconds, when I preview the video it has only the 10s I wanted. The problem is that I'm wasting a lot of time with this issue, having to turn the camera on and off all the time.... and I'm currently working on a video project. I'm using a micro SDXC with an adapter, could that be the problem? This is my memory card: Kingston MicroSDXC I U3 64GB Class10 This is happening like every 10 times I record, 5 of them I have this issue...Does anybody know why?
