Introducing 3D LUTs
Your URSA Cine can apply 3D LUTs to images on the touchscreens and all outputs. LUTs work
by telling your camera what color and luminance output to show for a particular color and
luminance input. For example you may want to record internally in camera with normal color but
send a preview out to your monitors and switcher of what broadcast legalcolors for your region
will look like. This is also useful when shooting Blackmagic RAW footage or using ‘film’ dynamic
range, both of which have an intentionally undersaturated, ‘flat’ appearance. Byapplying a LUT,
you can get an idea of what your footage will look like after it has been graded.
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 Cine can store up to thirty 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 any of your camera’s outputs.
Your URSA Cine 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.
For more information on displaying LUTs, see the ‘monitor settings’ section in thismanual.
Built in LUTs
Your URSA Cine provides a number of built in LUTs, that allow you to preview different looks
whilst shooting in ‘film’ dynamic range or when shooting Blackmagic RAW.
The Gen 5 Film Look LUT is a high contrast stylized look which provides the same color and
gamma to the default starting point you will get when you use DaVinci Resolve’s film look
creator plug in.

The Gen 5 Film Look LUT is a high contrast stylized look which provides the same color and
gamma to the default starting point you will get when you use DaVinci Resolve’s film look
creator plug in.
Gen 5 Film to Extended Video
Displays a wider dynamic range than the ‘film to video’ LUT, and applies a mild contrast change
with a smooth roll off in the highlights.
Gen 5 Film to Rec 2020 Hybrid Log Gamma
Displays a gamma curve that is suitable for HDR screens and compatible with standard dynamic
range screens.
Gen 5 Film to Rec 2020 PQ Gamma
Displays a gamma curve that is based on what we can perceive with our eyes, for efficient
encoding of HDR images.
Gen 5 Film to Video
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 Blackmagic URSA Cine alongside
other broadcast cameras using the REC 709 color space.
