## Setup Scene Collection

Scene Collection > new

Practicalli Study Group

Switch between scene collections in the Scene collection menu


## Set up scenes and sources

Switch between scenes to have a very smooth transition between video and audio sources.

For example, start a stream with a full screen webcam scene and then change to a desktop view with just a thumbnail webcam

Rename the existing scene to 'webcam full screen' and add a Video Capture Device as a source.  
Accept the properties defaults.  In the canvas, drag the corner of the video to fill the whole screen.   Add image sources for graphic overlays that add channel branding. 

Create and add a nice 3rd banner for the webcam view, with the tag line of the Practicalli channel, "Discover the fun in functional programming", book thumbnails (slideshow?), website address, github repo and twitter handle.

Create a second scene called desktop.  Add a Screen Capture source and call it laptop desktop.  Add a video capture device for the thumbnail of the webcam.  Use the existing webcam source and scale down in the canvas.  Add any other branding.

> Use the up and down arrows on the Sources menu to raise or lower a source, if it is hidden behind another source

Create a third scene called Editor that just includes the Emacs editor using the Window Capture source.
