At the request of the customer, we prepared two references, three options each. One was dedicated to budget animated series with a large number of commercials, the other was focused and expensive to produce.
The budget reference included 2D and 3D character themes, as well as moving balls. The client chose an easy-to-implement 2D animation. It included 30 videos of 3-5 seconds each, the cost of one animation was 26 $. You can see the result on Envato
The live footage reference also contained three scenes. We offered the options "World of the Future" with atmospheric space landscapes, "Office of the Future" with classic office scenes and "Dear Videos" with Lux class cars.
The customer chose luxury cars. Logical, as such clips will certainly be in demand on stocks. What is easier - to take a license for a video or to find a luxury car for filming?)
