About D-Movie function of Nikon D700
The D7000 is equipped with the D-Movie function that enables recording of high-definition movies (1920 × 1080p, 24 fps) exhibiting superior video quality. Autofocusing during movie recording is possible using contrast-detect AF. When the focus mode is set to Full time-servo AF (AF-F) and the AF-area mode to Subject-tracking AF, the camera automatically maintains focus on a subject moving throughout the frame in three dimensions. The D7000 also offers in-camera movie editing functions that allow users to save a single frame as a still JPEG image or delete unnecessary portions from the beginning or end of movie files.
Recording of stereo sound via an external microphone is also supported.
