Same people, new location

Genjutsu Background Change: New Place, Same Performance

To change the background of a video and keep the person and their movement, choose Background, add a photo of the new place as Image 1 and generate: the subjects, their outlines and actions and the camera move are kept, and lighting is matched to the new location. It is a generative edit, so people stay very close to the source but not pixel-identical; if the original pixels must not change, use masking instead. Genjutsu AI is an independent Genjutsu-style editor, not Higgsfield.

What stays and what adapts

  • Stays: the people, their outlines and actions, the camera move, the timing and the selected section's audio.
  • Adapts: the environment, lighting, shadows and reflections, so the people look like they were filmed there.

Location photo guide

  • A wide shot of the place, similar in angle to your clip.
  • Similar time of day and light direction to the source avoids harsh relighting.
  • Similar camera height (eye level, low angle) keeps the perspective believable.
  • Several images can show different parts of the place; 300–6000 px each.
  • Location images are sent as plain references, without the face review used for photos of people.

Background prompts

Beach at sunset
Move the scene to the beach in Image 1 at sunset. Keep both people, their positions and their walk; match the light and shadows to the new place.
Neon street at night
Replace the background with the neon-lit street in Image 1 at night, with wet pavement reflections. Keep the dancer unchanged.
Studio set
Move the action to the white photo studio in Image 1. Keep the people and the camera move; soft studio lighting.

Background change questions

Can I change the background and keep the person exactly the same?

The person, their outline, actions and the camera move are kept very close to the source, but a generative edit redraws every frame, so it is not pixel-identical. If the original pixels of the person must stay untouched, use background removal or masking and composite a new background instead.

Does the lighting match the new place?

Yes. The edit asks for lighting, shadows and colour to match the location in your image, which is the main advantage over a cut-out pasted onto a new background.

Can I use a video as the new background?

No. The new place comes from one to nine images; the motion comes from your source clip.

Does it work with several people in the shot?

Yes. Everyone in the shot is kept and only the environment changes. Fast motion and people crossing each other are where edges can shimmer.

Do I need a green screen?

No. The edit works on ordinary footage; you do not need to mask or key the subject.

Which model should I use?

Seedance 2.5 keeps the people and camera closest to the source (175 credits for 10 seconds at 720p). Reference models such as MiniMax H3 can make bigger changes but loosen the timing.

Keep the take. Change the world in it.
