How long can a 32 gigabyte SD card record on a Nikon camera?

The camera has a built in limit of just less than 30 minutes. Other factors may lessen that time, but that is the limit.

That depends on usage and settings and resolution you preferred

I will add to retiredPhil's answer

Video saved to a memory card is limited to a 4 gb file size. This is because all memory cards are formatted using FAT32 and that type format is limited.

In addition, any CMOS sensored camera that shoot video is limited due to the fact that CMOS sensors get hotter the longer they are active, so after you have shot two or three takes, the sensor is already quite hot so later takes will be very short, since the camera will shut off when the sensor gets too hot to protect the sensor.

The newer Nikon full frame cameras with a video feature can stream RAW video to an external hard drive, thus allowing much longer takes since NTFS formatting allow for huge files from any source, ot 4 gb limit.

You can avoid all this by shooting from a script. If you do that, your takes will be well under four minutes each and as you direct your actors, between takes, the sensor will have time to cool off.

There's an expensive alternative if you insist on shooting long takes and that is to have a sensor cooling system added to your camera. You will still be limited to 4 gb video files on a memory card, but the sensor will keep cool during you video production. See the link below.

EDIT: To answer your specific question, a 32 gb card will hold eight 4 gb video files. How long each take can be will depend upon the resolution you choose, HD or Full HD Your user manual will have a chart listing those times
