Hue vs Luminance color curve

*new since VEGAS Pro 20 update 2*

This curve enables you to define a hue or the average of a range of hues in the video and then adjust the luminance of just that color. This way you can control luminance levels that range from the entire video to very targeted areas of the video based on selected hue. For example, you could sample a range of blues and then increase the luminance to make the color look brighter.

Using the Hue vs. Luminance curve

  1. Add a video file to the timeline and select the video event.

  2. Click the Color Grading button to open the Color Grading panel.

  3. Navigate to the HSL Curves tab and select Hue vs. Luminance from the Curve Type drop-down list.

    The curve background shows a color spectrum that starts with red at the left, moves through various hues, and ends with red on the right. The white horizontal line in the vertical center of the spectrum depicts the curve.

Defining a range of color hues that you want to adjust

For instance, if you want to change the luminance level of the blues in your video, define a range over the blue shades in the spectrum.

  1. Double-click the curve on the left side of the desired color range to add a point to the curve.

  2. Add another anchor point on the right side of the color range.

  3. Double-click between the two anchor points you added to create a control point, adjusting the saturation of the defined color range.

    You can add as many other points to the curve as you want.

  4. Drag the control point vertically:

    • Any value above the mid line adds luminance.

    • Any value below reduces luminance.

The vertical line that runs through the point identifies a luminance spectrum that you can use to target the change you want. If you don’t see the change you expected as you move the control point, move it left and right as well as up and down.

Changing Saturation of Non-Selected Color Range

  1. Drag both anchor points defining the range to the bottom of the spectrum. This pulls the color out of everything outside of the range while with the middle point you can still add more saturation to the selected color if you want to.
  2. Adjust the range end points and add more points to the curve if needed for desired isolation effects.

Adjusting the luminance of the entire video

  1. Click the Reset button to restore the default curve settings.

  2. Double-click the curve to add a control point.

  3. Drag the control point up to increase luminance or down to decrease luminance.

    NOTE A single control point affects the entire curve and, consequently, the entire video.
