Short film animation licence?

I represent Dash Dot Creations - Polish animation studio specializing in 3D animation and special effects. In our portfolio you can find a couple hundred of animations for advertisements and games, as well as teasers, trailers and special effects. We have cooperated with game companies like CD Projekt Red, Vivid Games, Techland, Astragon, Qubic Games etc. We have our own Motion Capture studio and VR/360 section, so we were thinking about implementing Unreal engine into our pipeline. We wanted to use it to present animations recorded through motion capture. We think it would speed up our work and make the presentations more attractive. Thus the questions about the costs of using the engine in this way? Part of the presentations would be meant for commercial purposes, part of them for our own use only.
