Note: CineAsset uses a Gamma 2.2 defined by the ITU-R BT.709-5 specification. If the user wants to

use a mathematical 2.22, then he should use the custom input LUT option (see Figure 44).

o Use Custom input LUT - This option will allow the color conversion to be edited

manually using slides to adjust the gamma curves or by using a .csv LUT file.

o Offset - Adjust the image brightness.

o Gamma - Set the input de-gamma. exp. If the input is Rec709, which uses an encoding

gamma of 0.45, the correct setting would be 2.22 (1/0.45).

o Gain - Adjust the image contrast.

Figure 44: Use Custom LUT

Note: Custom LUT files accepted must be 12 or 16 bits with size equal to 512, 1024, 2048, 4096,

8192, 16394, 32768, or 65536.

• Use 3D LUT – this option will allow the use of a .3dl LUT file.
