This full-featured vision mixer has four HDMI inputs, with a Program output and Multiview Preview. It’s very capable for the size.
Inputs are selected using the buttons with a full-size T-bar for smooth transitions. Perfect for busy multi-camera events.
You can set the output to 720p, 1080i, or 1080p with frame rate conversion built in. There is also a complete audio mixer with separate analogue inputs and outputs.
