I filmed a two-minute clip, but I was surprised to see only 26 seconds of the clip, and the rest was deleted. However, I watched the entire clip on the camera, but on the PC, 80% of the clip was lost. Sometimes the camera stops working, and I have to restart it again so that I can use it. Is this normal and does it happen? Is Highlights (EH) reliable for work, or is it under development?
