NOTES
About Look files
- The camera supports Look Files (.cube format) in 17 grid or 33 grid format created with Blackmagic
Design's DaVinci Resolve or other software.
- Look Files with input ranges outside the 0 to 1 range in the header ("LUT_3D_INPUT_RANGE") are not
supported.
- Look Files 2 MB and larger, as well as files with a name containing over 65 characters are not supported.
- Only the following characters can be used in the file name:
Numbers 0 to 9, upper/lower case letters a to z, underscore (_), hyphen (-), period (.) and a single byte
space.
• If the correct input/output gamma curve and color space conversion are not selected, video will not be output
correctly.
• A Look File cannot be used if the [Gamma/Color Space], [HLG Color] or [Over 100%] settings are changed
after registering it.
• When the gamma curve component of the [Gamma/Color Space] setting in the custom picture is set to either
[BT.709 Normal], [BT.709 Standard] or [BT.709 Wide DR], super-white (video signal above 100%) and super-
black (video signal below 0%) levels of brightness will be clipped. When the video signal contains super-white
brightness levels, select
[Press] and then activate the Look File to apply it to a signal compressed to 100%.
• When playing RAW clips, the Look File registered when the clip was recorded will only be applied to the
thumbnail and not the clip itself.
