Full HD Video
The first Nikon DSLR to offer 1920x1080 full HD video, the D3100 can record it at 24 fps, plus, 1280x720p HD video at 30, 25 and 24 fps, and 640x424p at 24 fps. The 30 fps and 24 fps speeds are actually 29.97 and 23.976, respectively, to meet industry standards. Full-time servo autofocus while recording opens up new shooting opportunities. Videos are recorded as MOV files in AVCHD format with H.264 compression, with a maximum individual clip length of 4 GB per 10 minutes. Sound is mono via built-in microphone.
Easy Live-View/Movie Access
The D3000 features a button that provides easy entry to Live View mode. The D3100 uses a lever for that, with an adjacent button to start and stop movie recording.
3.0-Inch Live View LCD
The D3100’s Live View LCD monitor doesn’t swivel like the D5000’s, but it’s bigger—3.0 vs. 2.7 inches. Resolution is 230,000 dots, same as the D3000’s.
Maximum Memory
The D3100 can record images and video to the new high-capacity SDXC cards, and also is compatible with SD and SDHC.
Live View Scene Auto Selector
When using Live View mode, the camera automatically matches the mode to the shooting situation. Scene Recognition System in Live View automatically optimizes exposure, autofocus and white balance.
