I installed alternative firware, it supposed to make 4GB file and then start new one. But there is a bug and it does not continue. But that 4GB should be enough (about 80 minutes), I installed it anyway. Original firmware did 20 min parts.

This jumbo model feels very promising, it's decent battery out of the box and viewing angle is pretty wide even without addional lenses.
