New Curves in MasterGrade (What's New in 2022.2)

New curves enhance MasterGrade colour grading capabilities.

Flame Learning Channel: Grading with Advanced HDR Curves

New colour curves are now available in MasterGrade, in the Curves menu.

CurveMenu nameUsageX-axisY-axis
Hue vs HueH vs HChange any hue for a specific colour.The colour spectrum from 0° to 360°.A colour spectrum delta from -180° to 180°.
Hue vs Saturation GainH vs SSaturate and desaturate a specific colour.The colour spectrum from 0° to 360°.The saturation delta from 0.5 to 1.5.
Hue vs Luma GainH vs LIncrease and decrease the luma of a specific colour.The colour spectrum from 0° to 360°.The luma delta from 0.5 to 1.5.
Luma vs Saturation GainL vs SSaturate and desaturate colours based on their luma levels.The luma level from 0 to 1 in Video/Log and -7.5 to 7.5 f-stop in Linear.The saturation from 0.5 to 1.5.
Luma vs LumaL vs LIncrease and decrease the luma of pixels based on their luma levels.The input saturation level from 0 to 1 in Video/Log and -7.5 to 7.5 f-stop in Linear.The output saturation from 0 to 1 in Video/Log and -7.5 to 7.5 f-stop in Linear.
Saturation vs SaturationS vs SSaturate and desaturate colours based on their saturation levels.The input saturation level from 0 to 1.The output saturation from 0 to 1.
Saturation vs LumaS vs LLighten or darken colours based on their saturation levels.The saturation from 0.5 to 1.5.The luma level from 0 to 1 in Video/Log and -7.5 to 7.5 f-stop in Linear.
HueHueChange any hue for a specific colour, but with constraints. These added constraints were added for the following benefits:
  • Smoother transitions in regions where hues are compressed.
  • Hues cannot fold over on themselves, so you don't have to worry about introducing artifacts.
The colour spectrum from 0° to 360°.A colour spectrum delta from -180° to 180°.
Note: There is a limit to the number of control points a curve can have. This limit is 30 points for each curve in the RGB graph, and 60 points for the other curves.

About Curves and the MasterGrade Processing Pipeline

The curves are not rendered sequentially but in parallel. All curves are rendered after MasterGrade Primary and Tone controls.

Bypassing a Curve

A blue LED identifies the edited curves inside the curve selection drop-down and on individual buttons.

Bypass a curve by clicking the blue LED on the curve selection button.

Reset a curve by Alt+click the blue LED of the curve.

Plotting Colours

To work on a specific colour, use the Plot button.

To plot a colour:

  1. Click .

  2. In the Viewport, click the pixel to plot it on the curve.

    In addition to the plotted colour, two points are added to the curve, one on each side of the plotted colour. These points isolate the plotted colour, helping you edit only the colour you selected.

    Note: No points are added when a point exists nearby.

Note: If you click and hold instead of just click, the plotter becomes a picker with a zoom window. Use it to precisely pick a colour. If you have enabled Show Sampler Colours, a vertical bar indicates what colour you are currently picking.

The Plot button offers two modes:

  • Plot Front View samples the original, ungraded image.
  • Plot Current View samples the pixel as shown in the Viewport, with all the grading applied.

Gear Menu

Use the Gear menu to access many functions and preferences.

Display vertical lines that highlight the plotted colour on the curve:

  • Show Sampler Colours

Display a grid on the Curves canvas background:

  • Show/Hide Grid

You can display a vertical colour preview in the three Hue vs. curves. It appears when you move gesturally a point, and it gives you preview of the outcome.

  • Show/Hide Vertical Preview

Resets all curves in the MasterGrade node:

  • Reset All Curves

Frames the selected points on a curve:

  • Frame Selected

Frames all points of a curve:
