How do I record a ~45 minute 1080p video with external mic?
I emailed Google about this here is the response I got:

"Thank you for contacting Google. I appreciate your patience with me as I look into this issue. It seems as though the limit placed on the video data file of 2gb is written into the android operating system. This is in effect on all types of android devices.
I have researched a few video control apps, they follow the same rule and stop at 1.9-2gb. At this time I do not believe there is a work around for this issue. I do not have software update information available either. Some of the research I have done points to a possible legislative law that limits the video recording time of mobile devices as it takes away from video recorders."
