The simplest way to use Video Pencil in Ecamm Live is by using CueCam’s virtual camera. This way, all compositing will be done by CueCam and you can simply select it as a source in Ecamm.

However, you may have require more complex scenes than CueCam can create (e.g. multiple cameras, side-by-side layouts or using Interview Mode), in which case you’ll need to send Ecamm’s output to CueCam and use the Video Pencil transparent layer provided by CueCam.

This will allow you to see your Ecamm scene on your iPad and draw accurately with Video Pencil. You can just leave CueCam running in the background for the iPad connection alone.

IMPORTANT: You do not need NDI! CueCam creates an optimised connection between your Mac and iPad automatically.

Enable Virtual Cam feature in Ecamm Live’s Output menu.

Open CueCam’s Dashboard via the Live Camera, status bar menu (your Mac’s top right system menu) or via the Dashboard sidebar in a document.

Select Ecamm Live Virtual Cam as your main camera in CueCam.

Add a layer in Ecamm with the source “Video Pencil via CueCam”.

Make sure this layer fills the canvas (using the trackpad or mouse wheel is easiest) and lock it!

At time of writing (CueCan 2.0.4, build 94), you may need to keep CueCam’s Live Camera window open for this to work. In future versions this won’t be necessary.
