Video size limits?

[P a u l]

Nokia 820/wp8.1:
I find I can't record more than about 4GB of video (720p), or about 53 minutes. The video stops recording at that point. Are there software limits, or camera limits, anything? I can't find any published specs for this. I have a 64GB memory card.

That's because the file system your sdcard is formatted.. Fat32 lets you store files up to 4gb .. NTFS has no limits s as I can remember..

well that's a rather poor answer. He said he has 64 gb sd card and fat32 is not supported at sizes over 32gb. NTFS doesn't work very well on sd cards and is not supported by windows phone. What he has is exfat which has no limitations, yet windows phone will not record video files over 4gb. So why's that?
