camera - How do I record a video with a file size larger than 4GB on Galaxy S4 exfat SD card?

I've searched quite a bit and called Samsung tech support who didn't have any documentation on this issue. They all say that there isn't a limit on how much video you can record. I want to record class lectures, they run about 2 hours long. I set up the camera and tap record. Camera runs properly for about 30 minutes then says "Maximum File Size Reached" and stops recording. This happens to occur at a file size of 4GB about where you'd expect fat32 issues to occur. This is a Samsung SGH I337 from ATT Android Version 4.2.2

Here's what I've tried. The camera is set to record to the SD card. The SD card is exfat formatted. I can drop a 16GB .iso onto the card from my windows 7 computer through the phone via the usb cord with no issues. This leads me to believe there isn't a file size limitation from the format of the card. The SD card is NOT full it is a 65GB card with 40GB free.

Does anyone know of an app or a tweak that will let me record unlimited video within the real constraints of my hardware, 50GB's of 1080P video at a time or until battery failure?

Thanks for your time.
