How do I record a video with a file size larger than 4GB on Galaxy S4 exfat SD card?
I would change the video quality settings to a lower rez and try again
Leave it 16:9 At 1280x720 instead of 1920x1080. I would imagine your content will be watched on computers and iPads etc and not in imax theatres. You might get 2 hours out of that.

It is a stupid limitation .
I'm in the same boat so I'll keep looking. Maybe there are some developer options to fiddle with.

Cheers
