Let's say, I am rendering an animation and I am half-way in (frame-wise). I would like to save what has been computed so far and resume the rendering later. I can see that the generated .avi file is updating as the rendering goes, but I am not sure if Blender is smart enough to bootstrap from this file and concatenate more frames later.
Is it possible to save the progress of rendering using Cycles engine? If so, how?
Edit: Running on Blender 2.82
