AI Video Editor
This AI video editor changes a clip you already have by regenerating it from a written instruction: you upload footage, describe the change, and the model produces a new version of the same shot. It is not a timeline editor — there are no tracks, cuts or keyframes here. It does one thing, which is to apply a change to every frame of a clip at once.
That makes it the right tool for changes that would take an hour of rotoscoping and the wrong tool for anything a normal editor does in ten seconds. This route is not connected yet — the controls and prices are real, the Create button is not.
What "editing" means here
Every frame is regenerated. That is the thing to understand before deciding whether this helps you: the output is not your footage with an adjustment applied, it is new footage that resembles your footage plus the change you asked for. Grain, fine texture and small background detail will differ even in the parts you did not ask to change.
The trade is worth it when the alternative is masking a moving subject by hand. It is a bad trade when the change is one a conventional editor applies losslessly — a colour grade, a crop, a speed change, a title.
- Good: changing the season, the weather, the time of day, or the wardrobe of a moving subject.
- Good: restyling a whole shot — live footage towards illustration, or a flat phone clip towards a film look.
- Good: removing or replacing something that moves through frame and would otherwise need frame-by-frame masking.
- Bad: colour grading, cropping, trimming, speed ramps, stabilisation, adding text. Every one of those is better and cheaper in an ordinary editor, and does not regenerate your footage.
Write the instruction as a change, not a description
The prompt here works differently from text to video. There, you describe the whole scene because nothing exists yet. Here, the scene exists — so the prompt should name only what is different, and stay quiet about everything that should stay put.
Describing things you want unchanged actively hurts: mentioning the subject's face invites the model to regenerate the face, which is exactly what you did not want. Name the change, then stop.
| Goal | Prompt that drifts | Prompt that holds |
|---|---|---|
| Change the weather | A woman walking through a city street in heavy rain | Heavy rain; wet road surface |
| Change the season | A park with people in it during winter with snow | Winter: snow on the ground and the branches |
| Change wardrobe | A man in a red jacket standing on a balcony at sunset | His jacket is red |
Where prompt-based editing falls down
Faces are the first thing to go. A subject who is recognisable in your source clip is frequently not recognisable in the output, because the model regenerates them along with everything else. If the person matters, this is the wrong tool.
Text is the second. Signs, screens, packaging and captions in the source turn into approximations of letters. There is no prompt that fixes it.
And consistency across a cut is the third. Edit two clips of the same scene with the same prompt and the two results will not match each other well enough to cut together — the changes land differently in each.
When not to use this
- Anything a normal editor does: trimming, cutting, colour grading, cropping, stabilising, adding music or titles. Use a real editor; it is faster, free and does not regenerate your frames.
- Footage where a person has to stay recognisable. Faces drift when every frame is regenerated.
- Clips containing readable text you need to keep. Signs and captions come back as letter-shaped noise.
- Two clips that have to match each other after editing. The same prompt applied to two shots produces two different interpretations.
- Long footage. This works on clips of a few seconds, not on a finished edit.
- Fixing quality problems. Blur, noise and compression damage are not edits — use the video upscaler or video restoration instead.
Questions people ask
What is an AI video editor?
On this page it means editing by instruction: you upload a clip, describe the change in words, and the model regenerates the footage with that change applied. It is different from a conventional editor, which manipulates your original frames on a timeline and leaves them otherwise untouched.
Can I trim, cut or add music with this?
No, and you should not want to. Those operations are lossless in an ordinary editor and free in most of them. Regenerating your footage to achieve a trim would cost credits and give you back a worse version of the same frames.
Will the people in my clip still look like themselves?
Often not. Every frame is regenerated, faces included, so a recognisable person in the source can come back looking adjacent to themselves rather than identical. If preserving a specific face is the point, use video face swap, which targets the face directly instead of rebuilding the whole frame.
How long can the clip be?
A few seconds. This is a shot-level tool, not something to run over a finished edit. Cut the section you want to change, edit it here, and bring it back into your timeline.
How much does it cost?
It depends on the model, and the editor shows the figure on the Create button before you spend anything. Editing costs the same as generating, because the work the model does is the same — it produces every output frame either way.
Why did the background change when I only asked about the jacket?
Because the whole frame is regenerated, not just the region you named. Keeping the prompt to the change alone, with no description of the parts that should stay, reduces the drift but does not eliminate it.
