Default A camera with quality that of Nikon D3100 but records longer than 10Min.?

Also I want to know why is there 10 minute limit on Nikon D3100. Is this due to memory size because Nikon website says that no matter which Resolution you choose you will always get 10 Min clip.

The Nikon D5100 can record videos as long as 20 minutes.

Anyone care to elaborate....?

If you look at the specs for the D5100, max recording time is stated as 20 Minutes or 4GB (whichever comes sooner).

The maximum file size supported by FAT32 (the file system used by SDHC Cards) is 4GB (actually, it's 4GB minus 1 byte). See more about FAT32 here:


So, unless they wanted to split the recordings into multiple files, that's going to be a hard limit with that file system type.

Now, SDXC Cards (larger than 32GB, which is the limit of SDHC)) use an exFAT file system instead, and a number of newer cameras can use SDXC now. That file system is designed to get around some of the limitations inherent to FAT32 (eXFAT allows larger than 4GB file sizes, and larger than 32GB partition sizes). See more about it here:


But, there are other considerations, too. For example, cameras with larger sensors pushing a lot of data can overheat with longer recording times. So, manufacturers tend to place limits on recording time to prevent component damage from overheating.

Also, in some regions, how a camera is classified comes into the equation, with higher taxes if a camera is classified as a Video Camera. For example, it's my understanding that EU law imposes import tariffs of 4.9% if a camera is capable of 30 minute or longer recording times. So, you sometimes see limits of 29.x minutes to prevent those tariffs, even if a camera is technically capable of longer times. For example, you'll see that limit on some of the Panasonic models now (DMC-GH1, etc.).
