sp-create-video

Film a prototype. Turn a canvas board into a live-action clip of a real person using the product -- in an office, a lift, on the street -- with the interface itself kept pixel-exact rather than redrawn. Covers the animated motion board, rendering it to a reference video, generating the take with Seedance 2.5 on BytePlus ModelArk or Volcengine Ark, the prompt patterns that hold a screen verbatim and keep subtitles out, reviewing a take frame by frame, and the green-plate composite for when the model will not hold the interface. Use when asked for a demo video, a launch or marketing clip, a video mockup, an app-in-the-wild or UGC-style shot, or any video of a prototype being used by a person.
