RAW video is a video file that is output directly from the camera's image sensor without any in-camera image processing (RGB data before demosaicing)*. Like RAW still images, RAW video f iles record rich image information (tonal gradation, etc.), meaning they offer greater flexibility in color grading compared to Log video or video recorded in-camera. This makes them ideal for shoots where postproduction is going to be required.
* Noise reduction, lens aberration compensation and electronic VR are generally performed by in-camera processing. Since RAW video files are not subject to in-camera processing, users need to apply these adjustments as necessary during post-production, by using third-party software.
Nikon's RAW video output function outputs 12-bit RAW data via HDMI connector. The recording format depends on the specifications of the external recorder connected via HDMI. Recording to the camera's memory card is not available. RAW video output is compatible with the Atomos Ninja V ver.10.2 (hereinafter called “Ninja V”), recording in the ProRes RAW* file format.
