LightSpace CMS integration with madVR HTPC

Initial Operation

madTPG Calibration

Calibration of displays connected to a madVR based Home Cinema system using LightSpace CMS is exceptionally simple, with integration for profiling and LUT upload.

mdVR Upload

The Upload menu is located under 'File/Upload'.

Prior to profiling make sure the the Brightness and Contrast settings for the display have been set as per the Initial Display Set-up guide.

Profiling & Calibration Operation

To activate the madVR Patch Generator navigate to the desired profiling mode within LightSpace - 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 madVR patch generator will mimic the colour displayed, using the patch size pre-set via the 'Upload' window.

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

LUT Upload

After profiling a Calibration LUT can be generated as normal, and with the LUT held within LightSpace navigate back to the 'Upload' menu, and with the 'NULL Cube' tick box un-ticked, the present LUT displayed within LightSpace can be 'Uploaded' into the select 'Gamut Slot' within madVR

In this way, many different LUTs can be held within LightSpace CMS and quickly and easily uploaded into madVR as needed.

madVR LUT and VideoScale

For all generated LUTs, after the calibration LUT has been generated via LightSpace CMS in the normal way, use the 'Edit/LUT Manipulation/VideoScale' functions to format the LUT data as required, using VideoScale Pass Black, or VideoScale Clip Black functions as required.

Normally, for data range image path workflows, VideoScale would not be needed. However, madVR uses a video level workflow for both video and data ranges, so all LUTs loaded into madVR will need to have one of the VideoScale functions applied regardless of TV Legal or Data ranges being used.
