The data can be embedded in a line between lines 9 and 20. SR Live Metadata is embedded in line 14 by default. When the output format is 3G-SDI Level B/HD-SDI, SR Live Metadata is also embedded in the 2nd field. SR Live Metadata input HDR SDR Relation Table data included in the input signal can be applied to the conversion settings. The following two modes are supported. Apply Once: Data is applied only when an import operation is performed. Apply Continuously: The input metadata is continuously loaded and the data is always applied. Note There will be a delay of several frames when applying the data. HDR Look Function The HDR Look is a settings that determines the basic Look (visual performance, attractiveness) of the HDR video. This is a basic setting that determines how the image captured by the camera will be displayed on the display as an HDR image. You can select from the following three settings. Live: Characteristics based on the traditional Look derived from current SDR images. A powerful image with strong contrast and high color density. Wide dynamic range with substantial image brightness, capturing highlights without overexposure. Mild: Based on the Live Look but with an overall milder image characteristic. Natural: HLG original Look. Calm, gentle color density. The actual sensitivity setting is reduced, but with better S/N ratio. (Natural Look can be selected only when the output signal OETF setting is HLG.) Look Conversion Function When converting from HDR to HDR, the basic characteristics of the video (HDR Look and HDR Black Compression) can be converted at the input and output. To use the Look conversion function, AIR MATCHING and ADDITIONAL PAINT must be set to ON. 17
