It is easy to create 3D LUTs using DaVinci Resolve or other color correction software, and LUTs
are available online from a variety of sources. Your URSA Broadcast can store up to six 17 point
or 33 point 3D LUTs, of up to 1.5 megabytes each. Once loaded, you can choose to display
a given LUT on your camera's LCD touchscreen, front SDI, main SDI or any combination of
these outputs.
Your URSA Broadcast supports 33 point 3D LUTs in .cube format created in DaVinci Resolve
and 17 point 3D LUTs converted to Resolve .cube format via LUT conversion programs.
Your camera processes 3D LUTs using high quality tetrahedral interpolation.
Built-in LUTs
Your URSA Broadcast provides a number of built-in LUTs, that allow you to preview different
looks whilst shooting in 'film' dynamic range or when shooting RAW.
Broadcast Film to Video
The 'Broadcast Film to Video' LUT is similar to the REC 709 color standard for high
definition video, and has a high level of contrast and saturation. You may find this
setting useful when using URSA Broadcast alongside other broadcast cameras limited
to the REC 709 color space.
Broadcast Film to Extended Video
The 'Broadcast Film to Extended Video' LUT offers a preview with a wider dynamic
range than the 'Broadcast Film to Video' LUT, and applies a mild contrast change with a
smooth roll off in the highlights.
Broadcast Rec 2020 Hybrid Log Gamma
The 'Broadcast Rec 2020 Hybrid Log Gamma' LUT offers a preview that is essentially a
hybrid between REC 709 and a log image.
Broadcast Rec 2020 PQ Gamma
The 'Broadcast Rec 2020 PQ Gamma' LUT offers a preview with a gamma curve that is
based on what we can perceive with our eyes, for efficient encoding of HDR images.
LUTS buttons
The button icons along the bottom of your URSA Broadcast's 'LUTS' screen correspond to the
following functions:
Load
Manage
Delete
TIP
For more information on displaying LUTs, see the ‘monitor settings’ section in this
manual.
NOTE
LUTs are used as a preview tool only. Your URSA Broadcast does not apply, or
‘bake in,’ LUTS to recorded footage, however information on the LUT applied during a
shot is saved as metadata with your recordings. The 'LUT used' field in DaVinci Resolve
can be used to verify the name of the LUT that was used as a monitoring LUT on set.
