อ้างอิง Video Mode The parallel advances made in sensor technology and Internet video distribution have helped create the ability to capture and broadcast video footage. In turn this has put pressure on many professional photographers to capture clips alongside their stills. In addition, the broadcast and movie industries have adopted the EOS 5D Mark II to a degree that appears to have surprised even Canon. As a result, it's not surprising that the D800 features a very advanced, and well-integrated video mode, offering almost exactly the same functionality introduced in the D4 including a headphone outlet for monitoring audio and the option to record uncompressed video to an external drive via HDMI. Like the D4, the D800 features a headphone port for audio monitoring of video capture during filming. There are 20 adjustment levels for audio recording (plus auto) and monitoring volume can be adjusted in 30 levels.Uncompressed HD video footage can be sent out of the camera, straight to an external drive via the built-in HDMI port.
