Hi Everyone,
First post here, love this camera but I wanted to see if I could help shed more light on this
I use a Samsung 64GB card. This issue has crept up on me very recently.
Had it happen twice today. And have the exact same issue. After recordings that last approx 20 minutes, when I arrive at my destination, I press the start/stop button and the camera does not give me the three beeps saying it's stopping. I can't see the screen when I press it so I've not been able to confirm that it's showing that it's recording before pressing the start/stop button.
The video has always been long enough that a new file is created, on one video, I think that may be what triggered the issue as I noticed it just wasn't recording.
I have an external mic plugged in and I know it works, and love using it, it's a stereo mic. What I've noticed when this happens, is that the first video file in the recording has the audio recorded from the internal mic, even with the external plugged in. Once the second file is created, it is using the external mic. This was verified both because I was talking in my helmet and my voice was inaudible for the first clip, but the wind was overwhelming, and in the second clip, my voice was crystal clear and the wind was nearly non-existent. Also, when checking the details under the MP4 file properties, the sound was shown as mono for the first clip and stereo for the second. The second is always an automatically created clip.
I've had it happen twice today, once on my way to work, and once on my way home for lunch.
I've since tried to recreate it, both times with a formatted card. Once with the camera on before plugging in the mic, and with the mic unplugged during recording with no effect to the stereo/mono status of the tracks (sound was affected of course). The second time, with the camera turned on with the mic already plugged in.
My trip back to work after lunch it did not occur.
This is really confusing, but I am trying to run a motovlog and while I can deal with the UI freezing at the end of recording as the camera shuts itself off in a minute, the internal mic being used is detrimental.
