BMD Resolve User Guide

LightSpace CMS can be integrated with BMD's Resolve system for accurate display profiling and LUT generation, enabling Closed Loop display profiling.

The following instructions are for calibration of Displays connected to Resolve with LightSpace CMS.

Resolve Operation

Dolby Calibration

Calibration of displays connected to Resolve using LightSpace CMS is exceptionally simple, with Resolve acting as the pattern generator, and also able to provide output LUT capability.

Initial Setup

Calibration of displays connected to Resolve via a dedicated video output card using LightSpace CMS is exceptionally simple, with Resolve acting as the pattern generator.

  • Connect the display to be calibrated to Resolve's dedicated video output card.
  • Connect the Resolve workstation to the LightSpace PC via a dedicated network cable.
    (WiFi may work if the bandwidth is good and there are no interrupts... but it is not guaranteed as an interrupts will cause sync problems!)
    (LightSpace can also be run on the same PC as Resolve.)
  • Open Resolve, and open LightSpace CMS.
  • Select the 'Network Manager' menu within LightSpace, which controls synchronisation with Resolve.
  • Select Enable to active the Network Manager.
Resolve Calibration

The Network Manager menu is located within the top-level icons.

Note: The 'Patch Indent/Size' controls define the size/position of the patch to be displayed. To see more about the Patch Indent/Size controls see the Direct Profiling page of the website.

However, due to Resolve limitations it is not possible to use all the available LightSpace patch colour controls.

Also, make sure your Resolve project is 'clean' and has no 'weird' colour management configurations!

Direct Connection
  • In Resolve, swap to the Color menu , and using the top menu options navigate to Workspace/Monitor Calibration/LightSpace.
    (Make sure your timeline in Resolve is not empty...)
  • Type in the network IP address that LightSpace lists in the 'Server IP Addresses field.
    (If LightSpace and Resolve are on the same PC 'Localhost' will work.)
  • Press 'Connect' to connect Resolve to LightSpace CMS.
    (The LightSpace Network Manager will now show '1 available client/s'.)
  • Leave the Resolve LightSpace menu window open
  • Close the LightSpace CMS 'Network Manager' window.

Resolve Calibration

Profiling & Calibration

To activate the internal Patch Generator within the Resolve navigate to the desired profiling mode within LightSpace CMS - Calibration Interface, or Display Characterisation.

When the patch window is activate within LightSpace (the LightSpace CMS internal floating patch window has been made active by clicking the small colour display box when using Quick Profiling or Manual Measure modes) the internal patch generator within Resolve will mimic the colour displayed on the display connected the Resolve's video output card.

Profiling can then be performed as normal, using the probe connected to LightSpace, and with Resolve displaying the required patches on the display being profiled.

LUT Use & Verification

After profiling, a Calibration LUT can be generated as normal, and used where required, either within Resolve, a LUT box, or uploaded directly into a suitable display.

Due to the way the Patch Generator is implemented within Resolve you cannot use it to verify any active LUT used within Resolve (the Patch Generator is after the LUT...), so verification needs to be made via the 'Active LUT' capability within LightSpace CMS.

Known Issues

There are a number of known issues with Resolve when used as a patch generator.

  • For patch generation, if Resolve is set to 10 bit output it appears that the conversion from the 8 bit triplet value LightSpace sends to Resolve is 'bit-shifted' to 10 bits, which causes colour errors in the patch displayed. Setting Resolve to 8 bit output works correctly.
    (This may be graphics card dependent, but has not yet been proven.)
  • Resolve cannot use the 'Background Colour' options within the LightSpace Network Manager, and the BG colour must be left set at Black.
  • The 'Patch Scale' option with LightSpace is not correctly actioned within Resolve if used to define a 16-235/16-255 range. Only 0-255 can be used.
    The in-built levels rescaling within Resolve must be used for any signal levels conversions.
  • If trying to use the Resolve Patch generator on the GUI display, it may be necessary to set Video Monitoring in the project bit depth to 8 bit.
    (This also may be graphics card dependent, but has not yet been proven.)
