HDR movie recording The camera can record HDR movies when a gamma from [HLG], [HLG1] to [HLG3] is selected in the picture profile. Picture profile preset [PP10] provides an example setting for HDR recording. Movies recorded using [PP10] can be viewed with a wider range of brightness than usual when played back on a TV supporting Hybrid Log-Gamma (HLG). This way, even scenes with a wide range of brightness can be recorded and displayed faithfully, without looking under or over-exposed. HLG is used in HDR TV program production, as defined in the international standard Recommendation ITU-R BT.2100. Items of the picture profile Black Level Sets the black level. (-15 to +15) Gamma Selects a gamma curve. Movie: Standard gamma curve for movies Still: Standard gamma curve for still images Cine1: Softens the contrast in dark parts and emphasizes gradation in bright parts to produce a relaxed color movie. (equivalent to HG4609G33) Cine2: Similar to [Cine1] but optimized for editing with up to 100% video signal. (equivalent to HG4600G30) Cine3: Intensifies the contrast in light and shade more than [Cine1] and strengthens gradation in black. Cine4: Strengthens the contrast in dark parts more than [Cine3]. ITU709: Gamma curve that corresponds to ITU709. ITU709(800%): Gamma curve for confirming scenes on the assumption of shooting using [S-Log2] or [S-Log3]. S-Log2: Gamma curve for [S-Log2]. This setting is based on the assumption that the picture will be processed after shooting. S-Log3: Gamma curve for [S-Log3] with more similar features to film. This setting is based on the assumption that the picture will be processed after shooting. HLG: Gamma curve for HDR recording. Equivalent to the HDR standard Hybrid Log-Gamma, ITU-R BT.2100. HLG1: Gamma curve for HDR recording. Emphasizes noise reduction. However, shooting is restricted to a narrower dynamic range than with [HLG2] or [HLG3]. HLG2: Gamma curve for HDR recording. Provides a balance of dynamic range and noise reduction. HLG3: Gamma curve for HDR recording. Wider dynamic range than [HLG2]. However, noise may increase. [HLG1], [HLG2], and [HLG3] all apply a gamma curve with the same characteristics, but each offers a different balance between dynamic range and noise reduction. Each has a different maximum video output level, as follows: [HLG1]: approx. 87%, [HLG2]: approx. 95%, [HLG3]: approx. 100%. Black Gamma Corrects gamma in low intensity areas. [Black Gamma] is fixed at "0" and cannot be adjusted when [Gamma] is set to [HLG], [HLG1], [HLG2], or [HLG3]. Range: Selects the correcting range. (Wide / Middle / Narrow) Level: Sets the correcting level. (-7 (maximum black compression) to +7 (maximum black stretch)) Knee Sets knee point and slope for video signal compression to prevent over-exposure by limiting signals in high intensity areas of the subject to the dynamic range of your camera. [Knee] is disabled if [Mode] is set to [Auto] when [Gamma] is set to [Still], [Cine1], [Cine2], [Cine3], [Cine4], [ITU709(800%)], [S-Log2], [S-Log3], [HLG], [HLG1], [HLG2], or [HLG3]. To enable [Knee], set [Mode] to [Manual]. Mode: Selects auto/manual settings. Auto: The knee point and slope are set automatically. Manual: The knee point and slope are set manually. Auto Set: Settings when [Auto] is selected for [Mode]. 192
