KIC InnoEnergy company, that has its branch also in Krakow, among others conducts master studies in engineering and entrepreneurship of sustainable energy. Swedish branch of the company asked us to prepare a short animation film for KIC InnoEnergy Master School. We started just after taking a look at the brief. For the first two weeks we worked on screenplay and the lector text. The next step was a graphic design and an animation. At the very end we combined the movie with a sound and voice record. After long hours of work on animation and many modifications we finally get the result, that satisfies us and the client. We present it proudly.
