Introducing 3D LUTs
3D LUTs can be applied to images on your camera's LCD touchscreen and HDMI output. LUTs
work by telling your camera what color and luminance output to show for a particular color and
luminance input. For example, a LUT may tell your camera 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. Up to 10 17 point or 33 point 3D LUTs up to
1.5 megabytes each can be stored on the camera. Once loaded, you can choose to display
a given LUT on your camera's LCD touchscreen and HDMI output.
Your Blackmagic Pocket Cinema Camera 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 Pocket Cinema Camera 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
A number of built in LUTs are provided that allow you to preview different looks when shooting
in 'film' dynamic range or Blackmagic RAW.
Each camera provides LUTs that are specific to Gen 5 color science:
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 Pocket
Cinema Camera alongside other broadcast cameras using the REC 709 color space.
