Hello. The first camera often was locking for 1080p 60fps. So you're never sure if or not the recorded. Then she broke down. Amazon immediately sent me a new one. Thank you. This one is also blocked during 60 or 1080p 50fps. It is sometimes even slower than the sd card but I tried several class 10 card and it's like. The video quality is good, but I do not advise it. Except when using a lower flow rate. Eg. 1080p 30fps. But the picture is not as good and fluid.
