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].
Max Point: Sets the maximum point of the knee point. (90% to 100%)
Sensitivity: Sets the sensitivity. (High / Mid / Low)
Manual Set: Settings when [Manual] is selected for [Mode].
Point: Sets the knee point. (75% to 105%)
