How to remove a person from a video with AI (and what fills the gap)

Last checked against the product on

To remove a person from a video on LazyKiwi, upload a 4–15 second clip to the AI Video Object Remover and describe who to remove — “the man in the navy suit next to the flip chart”. The clip is re-rendered with the person gone and the background rebuilt behind them, for 4–12 credits per second plus 10: 5 seconds at 720p costs 50 credits.

How to use it

  1. 1

    Open the remover

    Video Generator → Tools → AI Video Object Remover, or open it directly.

  2. 2

    Upload the clip

    MP4, MOV or WebM, 4–15 seconds, up to 50 MB. Trim to the shot where the person appears.

  3. 3

    Describe the person

    Clothes plus position: “Remove the man in the dark navy suit standing next to the flip chart.” Add what should be behind them: “fill in the window and the floor”.

  4. 4

    Generate and check

    The button shows the price. Check the result; if the wrong person moved, name them more precisely and run again.

What fills the gap

The whole clip is re-rendered: where the person stood, the model draws what is most likely behind them — the rest of the wall, the floor, the street. It works best when that background is visible elsewhere in the shot (an empty floor, a window, a sky) and hardest when the person covers something unique the camera never shows.

Because the clip is re-rendered, small details elsewhere in the frame can shift. Check the result before you replace your original footage.

For the best result

  • Name one person per run, by clothing and position. With several people, run it again on the result for the next one.
  • Say what should replace them: “an empty skatepark”, “the window and the floor behind him”.
  • Steady, well-lit shots give the cleanest fill. Landscape and square clips have given steadier results than vertical ones in our tests.
  • Test at 480p (30 credits for 5 seconds), then rerun the wording that works at 720p or 1080p.

Limits

  • 4–15 seconds at 480p / 720p; at most 5 seconds at 1080p / 1440p.
  • A person who fills most of the frame leaves too little background to rebuild; crop or pick another shot.
  • Only edit footage you own or have the rights to edit.

FAQ

Can I remove a person from a video for free?

The 40 free credits cover a 5-second run at 480p (30 credits). Longer or sharper runs are priced on the button before you generate.

Do I have to draw a mask?

No. You describe the person in a sentence; there is no brush or tracking.

Can it remove a crowd?

One person per run works best. Remove the most visible people first, one run each, on the latest result.

Can it replace the person instead?

Yes, with Character Swap — the person becomes someone else rather than disappearing.
