# Remove Object From Video

> To remove an object from a video, upload a clip of 2–15 seconds to Kenerate Genjutsu, choose Free edit and write one sentence, such as "Remove the trash bin from the table; keep everything else the same." Genjutsu has no dedicated eraser, so results depend on the clip: small, still objects on simple backgrounds work best.

## Key facts
- Mode: Free edit (no dedicated remove mode)
- You give: The clip + one sentence naming the object
- Clip length: 2–15 s (Kenerate tiers) · 4–30 s (Seedance 2.5)
- Masking: None — you describe the object
- Works best on: Small, still objects, simple backgrounds
- Harder: Large or fast objects, occlusions, reflections
- Kenerate Genjutsu (Kenerate): Clip 2–15 s + up to 10 references → 480p, 720p or 1080p · ~2–4 min. Quick test runs on short clips with one small, still object.
- Kenerate Genjutsu Pro (Kenerate): Clip 2–15 s + up to 10 references → 480p, 720p or 1080p · ~3–6 min. A second try when edges or textures around the gap need more detail.
- Seedance 2.5 (ByteDance): Clip 4–30 s + up to 30 references → 480p to 4K · ~4–8 min. Longer clips up to 30 s and 4K masters.

## Steps
1. Trim a short test clip — Start with 2–5 seconds where the object is clearly visible. Short clips are quicker to check and cheaper to redo.
2. Upload it to Genjutsu — MP4 or MOV (WebM and M4V also work) up to 500 MB. Kenerate tiers read 2–15 s; Seedance 2.5 reads 4–30 s.
3. Choose Free edit — There's no remove mode — Free edit is the one that takes your own instruction, and it needs a prompt.
4. Name the object and what stays — "Remove the black trash bin next to the table; keep the table, the people and the camera exactly the same."
5. Compare, then decide — Check the spot where the object was in every frame. If it's not clean, try Pro, a tighter prompt — or Swap object or Change background.

## In depth

### Why removing is harder than swapping
When you swap an object, the new one covers the old one's spot. When you remove it, the engine has to invent whatever was hidden behind it — in every frame, consistently, while the camera and people move. That's why removal works best when the hidden area is simple: a plain wall, a tabletop, open sky, pavement.

### What makes a clip removal-friendly
If your clip ticks most of these, a Free edit removal is worth a try. If it ticks few, plan on Swap object or Change background instead.
- The object is small compared with the frame.
- It stays still, or moves very little.
- Nothing passes in front of or behind it.
- The background behind it is plain or repetitive.
- There's no strong shadow or reflection of it.
- The clip is short — 2 to 5 seconds for a first test.

### Fallbacks that often work better
Swap object turns the unwanted thing into something harmless that fits — a branded cup into a plain one, a parked scooter into a planter. Change background replaces the whole setting behind your subject, which hides clutter without asking the engine to invent a hole. For still photos, an image editor with a mask-based eraser is the more reliable tool.

## FAQ
Q: Can AI remove an object from a video?
A: Sometimes, and it depends on the shot. In Genjutsu you ask for it in Free edit: "Remove the bin from the corner; keep everything else the same." The engine re-renders the clip and fills the gap. Small, still objects on plain backgrounds have the best chance; leftovers or a smudge where the object was are possible, so check every frame.

Q: Does Genjutsu have an object eraser?
A: No. Genjutsu's modes are Replace character, Swap object, Change outfit, Change background and Free edit. Removal is something you request in Free edit, which takes any instruction in your own words. Swap object replaces things rather than erasing them, so pick Free edit for removals.

Q: Which objects are hardest to remove?
A: Large objects that cover a lot of the frame, objects that move fast, objects that pass in front of or behind people, and anything with a strong shadow or a reflection in glass, water or mirrors. In those cases the engine has to invent a lot of hidden background, and results are less reliable.

Q: Can I remove a person from a video?
A: You can ask Free edit to remove a background passer-by, and a small, distant figure on a simple background has the best chance. Removing a main subject who moves through the shot is much harder. Only edit footage you have the right to change, and don't use edits to misrepresent what happened.

Q: What should I try if the removal doesn't work?
A: Shorten the clip, make the prompt more specific about the object and what should replace it, or try Kenerate Genjutsu Pro. If the object still won't go cleanly, Swap object can turn it into something that fits the scene, and Change background can replace a cluttered setting behind your subject.

Q: Is there a free way to remove objects from a video online?
A: Genjutsu runs use credits, priced by clip length and resolution — the studio shows the price before you start. That's why a 2–5 second test clip is the sensible first step: you see whether the removal works on your footage before running a longer clip.

Q: Is the original sound kept?
A: Yes, by default. Genjutsu keeps the clip's own audio unless you switch it off, in which case the engine makes new sound to match the edit. Keeping it means voices and effects stay in sync with the action.
