Like A dream, everything happens so fast and so magical.

Starting from a usual day in office, travelling to the outer space, swimming in the ocean, being chased, falling from above and all that images linked to each other harmoniously like rings in a long chain.

Daniel Brown and Seeso are the artist behind this Trailer that is made for Seattle International Film Festival, the largest US film festival.

What makes this film footage so unique is the technique that was used.

Rotoscoping is an animation technique in which animators trace over footage, frame by frame, for use in live-action and animated movies. Originally, recorded live-action movie images were projected onto a frosted glass panel and re-drawn by an animator. This projection equipment is referred to as a rotoscope. Although this device was eventually replaced by computers, the process is still referred to as rotoscoping.
