How to 2D-stabilize and enlarge canvas to preserve outside pixels? I stabilize a movie clip of 1920x1080 using multiple markers and rotation stabilization.

Great, but a lot of it goes out of the original canvas. I know I could increase the influence so it almost stays in the canvas, but I want to preserve that large movement.

How can I enlarge the canvas so no pixel gets lost, while never rescaling the footage in order to preserve its maximum quality.
e.g. I would like to render a 3840x2160 video where my 1920x1080 footage is moving around in the middle, and I don't care how the rest of the canvas is filled.

NOTE: I spent hours putting those tracking markers already so I would like to preserve all this and simply enlarge the canvas.

Thank you!
Well... I found the answer and it's in fact quite simple.
Setting the rendering to a large resolution with scale 100%  is enough to do the job!

I used the nodes though, to connect Movie > Stabilize > Compositor.
