Kaiber

Kaiber made its name on music video work, including visuals for Linkin Park, and built audio-reactive animation that moves with a track. Its current product, Superstudio, is an infinite canvas where you chain image, video and audio models into flows, so you can storyboard, animate and restyle in one place. It's popular with artists who want a distinctive, painterly look rather than photoreal footage. Costs depend heavily on how many iterations you run, since previews and upscales all use credits.
