Introducing 3D LUTs
Your URSA Mini can apply 3D LUTs to images on its LCD touchscreen, front SDI and main SDI.
LUTS work by telling your URSA Mini what color and luminance output to show for a particular
color and luminance input. For example, a LUT may tell your URSA Mini to display a vibrant,
saturated blue when it receives a relatively dull blue input. This can be 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 Mini 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 Mini 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.
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 Mini 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. Blackmagic RAW lets you non-destructively embed a LUT you use during
filming into the RAW file for use in post production. This gives you the option in
DaVinci Resolve to use the LUT or apply a different look. For more information see the
'Embedded 3D LUTs' section.
Built-in LUTs
Your URSA Mini provides a number of built-in LUTs, that allow you to preview different looks
when shooting in 'film' dynamic range in ProRes or Blackmagic RAW.
Film to Extended Video
Film to Video
Film to Rec 2020 Hybrid Log Gamma
Film to Rec 2020 PQ Gamma
Displays a wider dynamic range than the '4.6K Film
to Video' LUT, and applies a mild contrast change
with a smooth roll off in the highlights.
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 Mini alongside other broadcast cameras
using the REC 709 color space.
Displays a hybrid between REC 709 and a log image.
Displays a gamma curve that is based on what we
can perceive with our eyes, for efficient encoding of
HDR images.
