Higgsfield Launches Genjutsu AI for Video Object Replacement

KEY FACTS

  • Genjutsu is a video-to-video model from Higgsfield that can replace objects or scenes in a video.
  • The tool preserves the original video's motion, camera path, and duration, changing only the surrounding environment.
  • Users upload a video and enter a prompt to replace products, props, or styles.
  • It supports output at 480p, 720p, and 1080p resolutions.
  • It uses one-time credit packs with no subscription, billed by input video duration.

PHYSIX OBSERVATION

Genjutsu turns video editing from a reshoot into a prompt change, making it an efficiency tool for advertising and short-video teams. But the realism of object replacement determines whether it can replace traditional post-production; if the results are stable, it could disrupt small-scale live-action shoots and green-screen demand.
