A 3D LUT is a simple but very powerful way to apply a color grade to footage. 3D LUT files are quite small, (often around 1MB) and can be produced with almost any color grading software, and can be saved on to USB flash drive for use on the monitor or at any point in post-production.
3D LUTs are particularly powerful when used with Portkeys monitors – many can be applied simultaneously on several pages so visualizing color variants onset is made as easy as swiping from page to page. We have some sample LUTS that you can download.
3D LUT Settings
- Access 3D LUT settings menu by swiping left on any page, then tap the 3D LUT icon, you can it is highlighted in the tool list.
2. Toggles the 3D LUT Off/On. You can select a LUT that is Stored from USB or import LUT from USB. Select the tool and activate or deactivate it as desired. Yellow tools are active, they are Grey when inactive.
Select this option and it will open a browser for your USB flash drive. There should be some default Internal LUTS that we have provided as a base, but we always recommend that you use one that is made for your production by either your DIT or Editor to give the closest results to Final.

Meet the above requirements as a valid document.
The LUT file name is required to be in English or numeric to avoid unrecognized, resulting in incorrect file names.
