Live video mixing / switching
Pearl 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 Pearl,
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 custom channel or layout .
Now on to the fun part!
There are two ways to perform live switching. You can use either the web UI or the touch screen.
Switching / mixing using the touch screen
Switching live video inputs, or video mixing, is simple and intuitive using Pearl's touch screen. Simply scroll to
the channel you want to work on, select the layout switching mode and apply the layout you want to use.
By default layout control is enabled for the touch screen, but it's possible your touch screen has been
configured by the administrator to prevent layout switching, or even channel monitoring. If the instructions
below don't work for you, see
Block (or allow) recording control from the touch screen for details on enabling
layout control by the touch screen.
To switch video using the touch screen:
1. If needed, touch the screen once to turn it on.
2. If needed, touch your channel in the grid view to change it to individual view.
3. If needed, touch the screen once to enable controls on the screen.
