To Configure the Hardware Channels

The number of hardware channels on your server depends on the configuration you purchased.

  1. Launch the Mira Config application.

    You may be prompted to allow the program to make changes on the computer, click Yes.

  2. Click the Channels tab.
    Note: Your selections may appear different, depending on the number of channels you have.


  3. Select the video processing mode and how you want the channels grouped.
  4. Select the default alpha (key) output that is used on a video plus key channel transport when no alpha channel is present in the clip or no clip is loaded.
    • Output BLACK on key output — the key (alpha) channel outputs a full frame of internally generated black.
    • Output WHITE on key output — the key (alpha) channel outputs a full frame of internally generated white. Use this selection if the output is going to a switcher as an auto-select key. The full-frame white alpha will force the entire video image onscreen.
  5. Click Apply.
