Apply prompt-guided visual changes to an existing video while preserving motion and timing. Upload source footage, describe the new look, and choose from nine edit strengths (Adhere, Flex, or Reimagine). Optional guide frames, multi-anchor keyframes, face, pose, depth, normals, and trajectory controls. Output 540p to 1080p with optional HDR. Ideal for color grading passes, seasonal restyles, game-trailer variants, and creative looks without reshooting.
