How to empty a room behind someone in a video
Upload the video and tell Vizard Agent what should go and what must stay. Vizard Agent cuts the person out across the whole clip, checks the outline, hair, hands and feet survived, generates a clean empty version of the room from one of its own frames, and composites them back together.
What do you type into Vizard Agent?
Say "keep the person exactly the same" in the same breath as the removal. Vizard Agent treats that as the fixed point of the whole job, and without it the safest interpretation is that everything in the frame is open to being rebuilt. No reference photograph is needed, because the empty room is generated from the footage itself.
Prompt
What does Vizard Agent actually do?
Emptying a room is not removing objects one at a time. It is easier to lift the person out, build the room they should be standing in, and put them back, so the furniture, the clutter and the door frame all go at once. The person is never regenerated. In the session behind this article it:
- Reviewed representative frames to understand the scene and how the person moves, and checked which tools could edit the setting while keeping the person.
- Cut the person out of the entire forty-five-second clip, preserving their movement, and checked the cutout's format, alpha and synchronisation.
- Confirmed visually that the cutout kept the outline, the hair, the hands and the feet.
- Generated a clean plate from a larger frame, with a continuous wall and no furniture, keeping the floor, ceiling and lighting consistent with the original framing.
- Composited the person onto it with the original audio, then investigated a visual error in the first render by checking the cutout's transparency pixels.
- Delivered 1920x1080 at 29.97fps, 44.57 seconds, with the original audio untouched.
When does this not work well?
Separating a moving person from a room and rebuilding what was behind them has limits in both halves, and they compound. Someone leaning on a desk can't lose the desk cleanly, shadows belong to the old room, and hair and hands are where a cutout fails first. A person lit by a lamp that no longer exists looks wrong, and mirrors show the room you removed.
Common questions
Does the person change at all? No. Vizard Agent composites the original pixels rather than regenerating the person.
Why remove the person first? Erasing furniture around a moving subject is a new problem on every frame. Vizard Agent lifts the person out once and generates one clean room.
What if they touch the furniture? That is the hard case. Contact points betray the removal, and Vizard Agent flags them rather than hiding them.
