Layer configuration menu description

Layer configuration menu is accessed by clicking on the Layer tab.

This menu provide:

  • A list of the available destinations and the layers associated with that destination.
  • Swap Z order button that allows for layers that are in the same Destination and of the same type to be swapped.

List of destination:

Swap Z order rules

There are several rules that apply when changing Z order:

  1. Can only swap Z order on layers in the same Destination.
  2. Can only swap Z order on layers that are of the same type (2K / DL / 4K).
How to swap Z order
  1. Click on Swap Z order button to enter in the Swap Z order mode.
  2. Click on 1 layer at a time and move it to a different location.
How to access the layer adjustments

Adjustments to layers are performed in the “Adjust” panel:

    When the layer is selected and is visible on the canvas, it will have a blue highlight around the layer.

  2. Click on the Adjust tab that is on the top of the adjustment area.

    The layer adjustment panel is displayed.

Note: It is possible to select multiple layers by clicking on the each targeted layer once Multiple Select is set to ON.
Layer adjustment panel description

The Layer adjustment panel allows access to general layer adjustments and takes effect only if a layer is selected.

Note: Layer adjustments are performed on individual layers. When multiple layers are selected, the adjustments are disabled.

The upper part of the panel is always visible:

This part includes:

  • Layer type: Layer can be a PIP or a Key. The available adjustments depend on the selected mode.
  • Keyframes: There are 2 KeyFrames per layer.

The lower part of the panel provides menus for layer sizing and color adjustments

  • Main adjustment : Border
  • Layer Window adjustment: Size, Position, Mask
  • Layer Color Effects adjustment: Brightness, Contrast, Gamma, Hue, Saturation, Monochrome, Invert

    Note: Layer Color Effects are not available on the E2 Lite processor.

PIP / KEY selection

The first selection is the choice for the layer type: PIP or a Key. Depending on the selection, the rest of the menu will adapt.

Layer adjustment panel > Main adjustment

The Main adjustment panel is variable according the Layer type.

Layer type = PIP (Border Tab):

This menu allows users to adjust the PIP borders.

  • Borders are enabled by selecting the type of to apply.

    Note: Only hard borders are available on the E2 Lite processor.

  • Border width and color are selected by adjusting the corresponding sliders or entering a figure in the adjacent edit boxes. The border width can be entered either in Percentage of the vertical size or in pixels.
  • The selected color is shown in the Current Color bar. The color can also be stored by clicking in one of the square boxes at the bottom of the menu next to the Learn button. These boxes are quick shortcuts to select that color for the Border.
  • Another way to specify a color is to click on the Color wheel. The slider values will change accordingly as the mouse moves around the color wheel.
  • Learn: The “Learn” button in the bottom is a way to store custom colors to be used for later. The way to use this area is to:

    1. Pick a color to save, using color wheel or the R/G/B adjustments.
    2. Click Learn button.
    3. Click any one of the buttons on the right.
    4. The color that was picked is now stored in this button.
Layer type = Key; Mode = Luma

A Luma (Luminance) Key is one in which the hole-cutting information is derived from the luminance (brightness) level of the key source.

Source on the Key Bus can be selected as the “cut.” You can select Self or Matte, Preset Bus or Split for the “fill” source.

Clip: Adjust the threshold of the video that “cuts” into the background. A hole is cut into the background anywhere that foreground luminance is greater than the clip level.

  • Range: 0.00 to 1.00, in .01 increments
  • Default: 50.00

Gain: Adjust the sensitivity of the key, enabling you to change the sharpness of the keyed image. Gain only affects the edge of the key hole, as set by the clip.

  • Range: 0.00 to 1.00, in .01 increments
  • Default: 1.0

Opacity: Adjusts the opacity of the keyed image, from fully opaque to fully transparent.

  • Range: 0.00 to 100.00, in .01 increments
  • Default: 100.00

Reset: Press to return all clip, gain and opacity settings to their default values.

Layer type = Key; Mode = Chroma

A Chroma (Chrominance) Key is one in which the hole-cutting information is derived from a color in the key source.

After selecting a Hue color to key out, it may be necessary to make additional adjustments to improve the look of the overall compositing effect.

Chroma Clip: This is an angle, centered around the Hue color. Any color inside this angle is fully keyed out.

  • Range: 0 to 100
  • Default: 10

Ramp: This is an angle, also centered around the Hue color. It must be equal to or larger than the Chroma Clip angle. Inside the Chroma Ramp angle, the colors keyed out ramp linearly the closer the foreground color approaches the Chroma Clip angle. Outside the Chroma Ramp angle, the foreground colors are not suppressed.

  • Range:0 to 100
  • Default: 90

Opacity: This allows the key source to become increasingly transparent with respect to the background source.

  • Range: 0 to 100
  • Default: 100

Hue: This field selects the color to be removed or keyed out of the input. While this can be manually adjusted, the "PICK HUE" feature also changes this number.

  • Range: 0 to 100
  • Default: 0

Spill: Spill removes unwanted “key” color, which is generally a result of reflection from the (green or blue screen) background, on the foreground object.

  • Range: 0 to 100
  • Default: 0

Shadow: This allows shadows to be preserved or removed in the foreground image (opposite of Highlight).

  • Range: 0 to 100
  • Default: 0

Highlight: This allows highlights to be preserved or removed in the foreground image (opposite of Shadow).

  • Range: 0 to 100
  • Default: 0

Saturation Clip: This defines the threshold along the Saturation axis where keying begins.

Below the clip threshold, the colors are not keyed out. Above the clip threshold, the colors follow the results of Chroma Clip and Gain, but they depend on the Saturation Gain setting as this creates a linear key color strength ramp in the key area.

  • Range: 0 to 100
  • Default: 5

Saturation Gain: This defines the transition along the saturation axis between keying off and keying on.

  • Range: 0 to 100
  • Default: 5

Reset:Press to return all clip, gain and opacity settings to their default values.

Pick Hue

The Pick Hue button allows the user to pick and apply a selected hue from any single Layer.

  1. Click on the Pick Hue button.

    Clicking on the Pick Hue button for a Layer places a crosshair on the Layer in Preview in the Programming Diagram area.

Layer adjustment panel > Layer Window adjustment

The following PIP Adjustment Menu functions are provided: (All figures are in pixels)

  • H Size — adjusts the PIP’s horizontal size.
  • V Size — adjusts the PIP’s vertical size.
  • H Position — indicates the PIP’s position, relative to the horizontal center of the screen (00), as measured from the exact center of the PIP. Thus, the value -34 is 34 pixels to the left of center.
  • V Position — indicates the PIP’s position, relative to the vertical center of the screen (00), as measured from the exact center of the PIP. Thus, the value 70 is 70 pixels above center.
  • Mask: The Mask Panel enables you to mask (crop) the top, bottom, left, and right edges of the PIP or key.
  • Reset All : Press to return all numbers to their default values.
Layer adjustment panel > Layer Effects adjustment
  • Layer Opacity: Adjusts the opacity of the layer.Opacity is adjustable within a range of 0 to 100. The default setting is 100.
  • Strobe: Toggles the strobe function on and off. When On, adjust the strobe Rate interval (in frames) to set the duration that the source is frozen until the next grab.
  • Flip: Flips the image within the PIP:

    • Off: The image is displayed in its original orientation.
    • H: to flip the image horizontally, along the Y axis.
    • V: Flips the image vertically, along the X axis.
    • H/V: Flip the image both horizontally and vertically, along the X and Y axes.
  • Freeze: Enables or disables the freeze action.

Note that almost all color correction effects (except “invert”) work on a keyframe by keyframe basis. This enables you to morph effects from keyframe to Keyframe.
