Kling O3 Video Edit: Change What’s in a Clip, Keep How It Moves
Kling O3 Video Edit takes a clip you already have and changes what’s in it. Swap the person, restyle the setting, replace an object, turn day into night. The camera, the choreography, the timing, and the cuts stay exactly as you shot them. You get the same clip back, same length, with your changes rendered in.
Tag the clip as @Video1 in the prompt, attach reference images as @Image1, @Image2 for the look you want, and describe the edit in plain words. Output at 1080p in Pro or in full 4K.
What can you do with it?
- Recast a performance. Attach a photo of the new person and tell O3 to replace the performer in @Video1. The gestures, lip movement, and timing carry over.
- Move a scene somewhere else. “Set @Video1 in a snowy forest like @Image1” keeps the action and rebuilds the background around it.
- Restyle footage. Turn a phone clip into anime, watercolor, or a film look, frame for frame.
- Swap wardrobe or props. Change the jacket, the car, the coffee cup, without reshooting.
- Change the weather or the hour. Rain, fog, golden hour, night. The clip’s motion stays.
- Clean up a shot. Remove a distracting object or a person in the background from a take you otherwise like.
How to use it
- Attach the clip. MP4 or MOV, 3 to 15 seconds, 720p or better, under 200 MB.
- Attach reference images. Up to 4: a face, a location, a style frame. Each becomes @Image1, @Image2 in order.
- Write the edit. Say what changes and what stays: “In @Video1, replace the woman with @Image1. Keep her movements, the room, and the lighting.”
- Pick model and audio. Standard, Pro, or 4K. Keep the clip’s original sound or mute it.
What you get
One video, the same length and framing as your clip, as mp4. The original audio is kept unless you mute it.
Tips
- Say what to preserve. “Keep the camera, the choreography, and the lighting” pins down everything you don’t mention, so the edit stays surgical.
- One edit per prompt. A single clear change renders cleaner than four stacked ones. Chain runs for bigger transformations.
- Use a frontal, well-lit photo for a face swap. Identity holds up through turns and profiles when the reference is sharp and straight on.
- Assign by position in the frame. With more than one person, say “the person on the left becomes @Image1” so nothing gets mixed up.
- Draft on Standard, finish on 4K. Same prompt, same clip. Check the edit reads right, then rerender the keeper.
- Trim first. Edit only the seconds you need. The clip has to be 15 seconds or under, and shorter clips render faster.
