Output settings

To manually create an output, click on the button.

You can edit the name of your output.

Then, adjust the part of the pixel workspace you want to display in this output, as well as the position and resolution of your output in your desktop.
Map: Adjust the top-left position and the size of the extracted area in your pixel workspace
Out: Adjust the top-left position and the size of your output in your Windows desktop

NDI Off/On button: Stream your output using NDI protocol. Please note that you cannot stream a warped output or an output with the X-Map feature

X-Map Off/On button: Activates the X-Map feature manually

Vertical Off/On button: Activate the Portrait mode if your video-projector is in Portrait mode for instance. When activated, Map width needs to be smaller than Map height (Portrait mode) but the Out width needs to be larger than your Out height (matching with the physical output of your graphics card).

Fill/Key Off/On button: Displays the Fill on an output and the Key (alpha level of the output converted to gray level) on the consecutive output. If, for example, you have one output with the top-left position at 0,0 and a resolution of 1920×1080 with this option activated, Modulo Player will automatically display the Key in gray level on the output with the top-left position 1920,0 and the resolution 1920×1080.

Mask sub-tab:

You can use a PNG still image as a mask on your output. It will use the alpha channel of your PNG as mask.

Color sub-tab:

Use this tab to adjust the color of each output. You can adjust the RGB gamma and level globally and/or by color channel.
Use the Reset button to quickly go back to neutral state.

Background sub-tab:

A background image can be displayed on each output to pre-warp prior to the installation. You can use a theoritical warping point of view as a background.

Soft edge tab:

You can adjust the soft edge on each side:
• Start: The start point in pixels to set up a crop
• Length: Soft edge length – starting from the start pixel
• Gamma & Gain: Adjust the transition curve
• BlackLevel: You can adjust the grayscale outside of the soft edge. It can help reduce the double video black on the soft edges.

Shape tab:

Use this tab to warp your output.

Configuration:

In the top button bar (see picture “Top button bar “ above) , click on the configuration button to edit the warp mode and the number of control points per row and column.

Choose the warp grid mode: Keystone or Curve mode.
Curve Mode allows you to change the number of control points by selecting a number of rows and columns.

*Curve Mode: We advise you to start with a small number of control points. If you need more flexibility, increasing the number of control points will not impact the warp result. However, decreasing the number of rows or columns will reset your warping entirely.
