Text-to-video and image-to-video create new footage. But much of the time you already have the footage and just want it to look different: night instead of day, a new outfit, a different background, an object removed.
Video-to-video editing applies changes to an existing clip while keeping the subjects and their actions. This article explains the workflow using Pixwit's Video to Video tool.
What the page offers
According to the page, you can restyle video, change backgrounds and outfits, replace subjects, remove objects, and recolor scenes with model-specific controls.
- Upload: MP4 or MOV, up to 200MB
- Reference images: up to 4
- Model: for example Kling O3, listed for 3–15.5-second video with up to 4 reference images
- Resolution: 720p, 1080p, or 4K, with an option to generate audio
- Edit instruction: a text description of the change
- Presets and a custom edit mode
The credit cost updates automatically with your inputs.
Writing an edit instruction
The example instruction on the page is a good model:
"Transform the scene into a cinematic night setting with blue neon lighting. Keep the subjects and their actions consistent."
Two parts matter: what changes and what stays. Always state both.
More examples:
- "Change the jacket to a red leather jacket. Keep the person, movement, and background unchanged."
- "Replace the background with a snowy mountain landscape. Keep the subject and camera motion."
- "Remove the car parked on the left. Keep everything else the same."
Tips
- Short, clean clips within the model's duration range work best.
- Use reference images for specific outfits, styles, or replacement subjects.
- Draft at 720p, then render finals at a higher resolution.
- Check consistency frame by frame for flicker or drifting details.
Use cases
Re-grading a shoot into a different mood, testing wardrobe options, cleaning up distracting objects, and producing stylized versions of real footage for social.
Example edits by goal
| Goal | Edit instruction |
|---|---|
| Change time of day | "Turn the scene into golden-hour sunset light. Keep the people, their movement, and camera motion unchanged." |
| Change season | "Add light snowfall and frost on surfaces. Keep the subject and action consistent." |
| Restyle | "Render the footage as a hand-painted watercolor animation. Keep composition and motion." |
| Wardrobe | "Change the person's shirt to a navy blazer. Keep their face and movements." |
| Clean-up | "Remove the trash bin on the right side of the frame. Keep everything else the same." |
Each instruction states the change and what must stay fixed, the two-part pattern shown on the tool's page.
When reference images help
Words have limits. If you need a specific jacket, a particular art style, or a replacement character, upload up to four reference images. The model can match a concrete visual more closely than a description. Use clean, well-lit references with plain backgrounds.
Limits to expect
- Fast motion and occlusion (people crossing in front of each other) are harder to edit consistently.
- Small details like logos and text may flicker or change between frames.
- Large changes, such as replacing an entire scene, are less reliable than targeted edits.
Start with targeted edits, review closely, and build up from there.
Responsible use
Don't alter footage of real people or events in misleading ways, especially news or documentary material, and get consent before replacing or altering identifiable people.
