Vision Mixer – Production switcher

An executive area – a Vision Mixer (production switcher), – occupies the middle part of 3D Production module screen. The mixer’s panel is composed of two rows of buttons with executive keys block on the right side of the screen. It is used to direct the chosen content on the air and to prepare the next materials for broadcast. See the image below.

Mixer buttons are located on Program and Preview lines. You can switch between different sources of signals on PGM and PVW by clicking the corresponding buttons.

The top line of buttons – PGM – indicates the image the source of which is sent directly on the air. The selected source button directed to be broadcast at the moment is highlighted in red.
The bottom line of buttons – PVW – allows you to indicate which image source will be aired next. An active button is marked in green. The chosen material is visible in the PREVIEW window.
