In the Movie Settings entry of the Shooting menu, you can make the following choices:
■ Movie Quality. Choose your resolution. Use the Movie Settings entry in the
Shooting menu. Or, when Live View is activated, and before you start shooting
your video clip, you can select the resolution/frame rate of your movie. Your choices
are as follows:
■ 1920 × 1080 at 24 fps, high quality, low compression.
■ 1920 × 1080 at 24 fps, normal quality, medium compression.
■ 1280 × 720 at 30 fps, high quality, low compression.
■ 1280 × 720 at 30 fps, normal quality, medium compression.
■ 1280 × 720 at 24 fps, high quality, low compression.
■ 1280 × 720 at 24fps, normal quality, medium compression.
■ 640 × 424 at 30 fps, high quality, low compression. (Useful for video clips dis-

WHAT FRAME RATE: 24 fps or 30 fps?
Even intermediate movie shooters can be confused by the choice between 24 fps and
30 fps, especially since those are only nominal figures (with the D7000, the 24 fps setting
actually yields 23.976 frames per second; 30 fps gives you 29.97 actual “frames” per
second).
The difference lies in the two “worlds” of motion images, film and video. The standard
frame rate for motion picture film is 24 fps, while the video rate, at least in the United
States, Japan, and other places using the NTSC standard is 30 fps (actually 60 interlaced
fields per second). Computer editing software can handle either type, and convert
between them. The choice between 24 fps and 30 fps is determined by what you plan
to do with your video.
The short explanation is that, for technical reasons I won’t go into here, shooting at 24
fps gives your movie a “film” look, excellent for showing fine detail. However, if your clip
has moving subjects, or you pan the camera, 24 fps can produce a jerky effect called “jud-
der.” A 30 fps rate produces a home-video look that some feel is less desirable, but which
is smoother and less jittery when displayed on an electronic monitor. I suggest you try
both and use the frame rate that best suits your tastes and video editing software.
