The EOS-1D Mark IV captures video with all the benefits of shooting with an EOS digital SLR. The HD recording area on the EOS-1D Mark IV is approx. 27.9mm x 15.7mm, similar when compared to the 24.89 x 18.65mm recording area of Super 35 motion picture film. By shooting video with a large sensor camera, photographers as well as videographers can take advantage of the creative features native to SLR photography. Along with its manual controls, the EOS-1D Mark IV allows for full use of Canon EF lenses, including wide angle, macro, super-telephoto, tilt-shift lenses and fisheye, providing a wealth of depth-of-field and other creative shooting options once reserved only for still photography. The resulting HD video is a standout in its stunning depth-of-field characteristics, remarkable capture capability under poor lighting conditions with its vast ISO range, and deep clean blacks with nearly undetectable noise.
When shooting HD video in AE modes, the EOS-1D Mark IV employs Center-Weighted average metering to help ensure stable motion-picture exposure with the camera automatically selecting the ISO speed, shutter and aperture. Full manual exposure control is also available while shooting video when the camera is set to Manual mode.
Video can be captured at 1920 x 1080 resolution at frame rates of 24 (23.976), 25 or 30 (29.97) frames per second, for up to 4GB per clip. Movies are saved as MOV files and can be viewed in Full HD with HDMI output. Other recording sizes include HD at 1280 x 720 (50/60 (59.94) fps) or SD/VGA at 640 x 480 (50/60 (59.94) fps). The EOS-1D Mark IV has a built-in microphone for simple mono recording and stereo sound can be recorded through a self-powered external microphone.
