To access the LUT settings, simply tap the Settings icon and select the LUTs Tab.
A LUT or Look Up Table is a table that transforms the color response and as such adjusts the ‘Look’ of the input. 3D LUTs have a combination of three inputs defining the combination of R, G, and B values allowing for adjustment of not only color but also gamma and gamut. LUTs can also be used to monitor the input in a specific color space or more creatively to create a specific ‘look’ such as film stock emulation or to match cameras.
It’s worth nothing that not all LUTs are equal and the majority of LUTs are designed to work with in the boundaries of REC.709. This means that whilst they may apply the color adjustments you are looking for they may also effect the luminance of the image and in which case these LUTs should only be used for delivery of content designed to be viewed in REC.709 or SDR.
If you are working with 3D LUTs you can use color correction applications, as well as applications like Davinci Resolve, Photoshop or dedicated applications like LUTCalc. to create you own custom Looks that can then be imported to your ATOMOS device. They can provide a great base or primary grade that allow you to apply an instant look to your footage.
ATOMOS support 3D LUTs in the industry standard .CUBE format and provides 8 LUT memory slots for your load your LUTs into.1D LUTs are not supported and will need to be converted via 3rd party software to be imported.
How to import LUTs to your SHOGUN CONNECT:
Copy the .CUBE files onto your media using a computer and compatible dock.
Tap on MON in the Information Bar across the top of the screen to access the monitoring tools settings and select the LUTs tab.
Tap on one of the numbered slots to select it. Slots that already have a LUT loaded will have a curve next to the slot number whilst empty slots will not.
Tap on the folder icon to access your media.
If you select a slot that already has a LUT loaded, you will be asked to confirm the fact that you want to overwrite the loaded LUT when you tap on the folder.
Navigate through the disk file system to the LUT file to be uploaded, and tap on the name of a LUT to select it. A second tap on the name will import the LUT to the selected slot.
A progress bar will appear on screen whilst the LUT loads.
The LUT has now been loaded and will be selected by default.
Repeat the process to store up to 8 LUTs on your SHOGUN CONNECT.
Once a LUT is loaded into your SHOGUN CONNECT, it cannot be deleted. Loading LUTs into a slot that already has a LUT loaded, will overwrite the loaded LUT.
How to apply a LUT to your image:
Tap on MON in the Information Bar across the top of the screen to access the Monitor Mode menu and select the LUTs tab.
Tap on one of the eight slot numbers to select a LUT to be applied to the display. Tapping on slots that have LUTs loaded will preview the name of the selected LUT (above the Menu bar).
Slots that have a LUT loaded will have a curve next to the slot number whilst empty slots will not.
Tap on the Monitor tab to open the the Monitor Mode menu.
Tap on the LUT icon to apply the selected LUT to your image. The name of the currently selected 3D LUT will be displayed next to the LUT icon.
The selected LUT file name will display at MON in the Information bar when applied to the image.
In the LUTs tab, the settings allow you to choose how the LUT will be applied:
If this option is selected, your SHOGUN CONNECT will bake the LUT look into the recording. When enabled, a CUSTOM LOOK icon will flash in the top corner of the monitor and the LUT cannot be activated during recording to avoid any potential issues with the recorded content.
Baking a LUT into your recording cannot be undone in post-production, so we advise that you consider your workflow before the use of this option.
Baking the LUT into your recording is not supported when recording with the ProRes RAW codec.
OUTPUT LOOK – With this option, the selected LOOK is also applied to the HDMI loop out of the SHOGUN CONNECT. This will allow for instant preview on a larger monitor or to be used with a wireless sender. This function can also be combined with the down convert option that can be found in the input menu.
During color management it’s likely that you may want to review a number of LOOKs and even compare them to the Native Video Source. Tapping the Compare option will apply a 50/50 vertical screen split that will show both the Natural Source Video and the selected LOOK of the LUT.
Please note that activating the 50/50 preview will also be applied to the Loop out and is not available when LUT is set to record.
Remember that you can remove all overlays by simply tapping in the center of the screen. Tap again to reveal the overlays.
