Live video mixing / switching

Live video mixing / switching

For local custom channels, Networked VGA Grid supports live video mixing (also known as live video 
switching) while you are capturing, streaming and recording. Video mixing is a great way to create dynamic 
content for your viewers and recordings. With Networked VGA Grid, switching happens in less than half a 
second ( < 500 ms)!

This means you can start your stream with a video source showing a countdown, move to a single-camera 
view, then switch between multiple cameras or multiple layouts with more than one source, and end again 
with a thank you message for attendees. (Layout switches made in your channel are reflected in both the live 
stream and recording. )

For example, your stream could look like this:

Before you can switch between layouts, make sure you have your custom channel with layouts created. See 

Create a local custom channel or layout

.

Now on to the fun part! 

There are two ways to perform live switching. You can use either the Admin panel or the Epiphan Live control 
interface.

Performing live switching in one interface (e.g. Epiphan Live) does not dynamically update 
the visuals in the other interface (e.g. the Admin panel). The other interface must be 
manually refreshed to accurately reflect the current live switching layout information.

Switching / mixing using the Admin panel

Switching live video inputs, or video mixing, is fast and easy using the Admin panel. For best results, you may 
wish to be in a location where you can see the live action, and have a solid understanding idea of what is in 
each of your layouts. Good layout names can help with this. See 

Rename a layout (custom channel)

.

To do live video mixing:

 1.  Login to the Admin panel as 

admin

.  See 

Connect to the Admin panel

.

 2.  Follow the steps in 

Custom channel layout editor

 or
