I needed something to create tutorials for my app. I wanted to capture the touches and pencil input but I didn't want to bake that into the capture (in case I want to selectively remove it.) It also makes multiple takes easier and some niceties like selecting audio channel and showing the last frame of your previous take to reset.
This also includes an OFX plugin that lets you render the data from that sidecar and change the color or size of touches and pencil input.
Without the framework, it can still record the screen, just not the touches.
Hope this helps someone!
