A dedicated movie-record button has been positioned near the shutter-release button for smooth starting and stopping of movie recording with a feel similar to that of still-image shooting. Full-HD movie recording at a frame size of 1920 x 1080 and frame rate of 30 fps is supported, and the H.264/MPEG-4 AVC video compression method has been adopted. Movies up to 29 minutes 59 seconds can be recorded. Image sensor sensitivity begins at ISO 200 and can be expanded to the same ISO 204800 equivalent possible with still-image shooting. Full-HD movies can be recorded with the D4 using one of three image areas: FX-based movie format, DX-based movie format, or 1920 x 1080; 30 fps/25 fps/24 fps crop. Read the article here:
