My Q8 Camcoder sometimes turn off when I was recording. I checked the battery and SD card spaces they all look perfectly fine. It is not a problem caused by battery and storage space. I could not find the reason why the camera suddenly blackout during my recording process which makes me very frustrated, and I cannot make a complete recording since I can not predict when it’s going to be dead.
This is due to a limitation of the .mov file, which the Q8 and Q4 use to record. The maximum size a .mov file can be is 4GB. Once this limit is reached while recording with the Zoom camcorder, it will begin a new file to continue further recording , if this does not happen check in the settings to see if you can continue recording after it has reached the 4gb file size.
