Applying a LUT to Video Outputs
While recording using special gamma curves, you can apply a LUT to video output from the VIDEO terminal (optional viewfinder), SDI OUT terminals, MON. terminals or HDMI OUT terminal. When a LUTis applied, the displayed image will look as if a standard gamma curve and color space were used, making it easier to check the image on the monitoring device used. To check the image on an external monitor, you will need a monitor that is compatible with the selected color space.
Available preset LUT options by gamma curve and color space
Available LUTs depend on the combination of gamma curve and color space used, whether it was set through one of the preset color settings or through the individual main settings in the custom picture file.

- Open the LUT selection submenu.
HOME screen: 
Monitoring menu: 
- Select the desired terminal and then press SET.
Using the control display, you can also select 
to apply a LUT to sub recording (XF-AVC Proxy) clips when the simultaneous sub recording is activated. From the monitoring menu select the LUT for XF-AVC Proxy clips with the 
instead.
- Select the desired LUT and then press SET.
Repeat steps 2 and 3 as necessary to select the LUT applied to other output terminals.
The gamma curve and color space of the video output will change.
If a LUT is not needed, select [Off].

BT.709 |
LUT for viewing on the optional viewfinder and external monitors compatible with BT.709 specifications. |
| [BT.2020]1 |
Wide DR |
BT.2020 |
LUT for viewing on external monitors compatible with ITU-R BT.2020 standards, which define parameters for ultra-high-definition television (4K/8K). |
| [DCI]1 |
DCI |
DCI-P3 |
LUT for viewing on external monitors that support color spaces and gamma curves that follow the guidelines established by DCI (Digital Cinema Initiatives). |
| [ACESproxy]1 |
ACESproxy |
ACESproxy |
LUT for viewing on external monitors compatible with the ACESproxy standard established by ACES (Academy Color Encoding System). The signal output will use full range coding. |
| [HDR-PQ (OOTF On)]1, 2, 3 |
[PQ (OOTF On)] |
BT.2020 |
LUT for viewing HDR (high dynamic range) images on external monitors compatible with the PQ standard defined by ITU-R BT.2100 standards. The signal output will use narrow range (video range) coding. Select [PQ (OOTF On)] for deeper blacks and higher contrast. |
| [HDR-PQ (OOTF Off)]1, 2, 3 |
[PQ (OOTF Off)] |
| [HDR-HLG]1 |

BT.2020 |
LUT for viewing HDR images on external monitors compatible with the HLG standard defined by ITU-R BT.2100 standards. The signal output will use narrow range (video range) coding. |

BT.709 |
LUT for viewing HDR (high dynamic range) images on the optional viewfinder and other monitoring devices. The LUT follows the ITU-R BT.2100 transfer function to convert a brightness range of 1600% or 400% respectively into a linear brightness scale. Select [(OOTF On)] for deeper blacks and higher contrast. |

1 Not available for the VIDEO terminal (optional viewfinder).
2 For the HDMI OUT terminal, this option is only available when
[HDMI Max Res.] is set to [1920x1080].
3 "OOTF" refers to the opto-optical transfer function defined by the ITU-R BT.2100 standard.
4 Only available for the VIDEO terminal (optional viewfinder).
NOTES
- When you apply the [ACESproxy] LUT to the SDI OUT terminals, MON.terminals or HDMI OUT terminal, the selected terminal will output ACESproxy video data. Using a compatible monitor*, you can perform on-set color grading and check the image after color correction as you continue shooting.
* When using the HDMI OUT terminal, a monitor that supports full range YCbCr quantization is required.
- If you set an assignable button to [LUT], you can press the button to turn on and off the LUTs applied to all video outputs at once.
- If you change the [Gamma] or [Color space] settings in the custom picture file, all the LUT settings will be reset to [Off].
