Story and Test in animation
I created ideas in screenshots of the story in trailer, but I had to choose a few images to create animation and shorten them to one minute.
I tested the animation with two different colours (one for sepia and one for black & white) but both test animations were only 13 seconds, so I needed more animation to target one minute or more.
I added more animation pictures and I checked into make sure everything worked. All images are perfect animation and it was ready for the final trailer.
