Introducing 3D LUTs

Your URSA Broadcast G2 can apply 3D LUTs to images on its LCD touchscreen, front SDI and

mainSDI. 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 Broadcast G2 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 your camera’s LCD touchscreen, front SDI, main SDI or any combination

of theseoutputs.

Your URSA Broadcast G2 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.

NOTE Your Blackmagic URSA Broadcast G2 does not apply, or ‘bake in,’ LUTs by default

to recorded footage, however you can choose to ‘bake in’ the LUT to your footage.

This can be a useful option for situations where you do not have the time to grade your

footage in post-production, or where you need to give the footage directly to a client

or an editor.

When you are using LUTs as a preview tool on set, the information on the LUT applied

is saved as metadata with your recordings. DaVinci Resolve can display this

information in the ‘LUT used’ field in the metadata tab, which can be helpful for

colorists to verify the name of the LUT that was used on set.

Built-in LUTs

Your URSA Broadcast G2 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.

 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

Broadcast G2 alongside other broadcast cameras using the REC 709 color space.
