How to Edit Videos with AI

Start with one clear shot, name one change and specify what should stay. This guide shows how to prepare footage, use image references and review an AI edit across the whole clip.

Source and instructions

Decide what the source should preserve

Direct a specific change in existing footage, from wardrobe to scene lighting. The source clip supplies the action and camera movement.

Prepare one readable shot

Trim longer footage before upload. Choose a segment where the target stays visible; hard cuts, heavy motion blur and long occlusions make an edit harder to judge.

Write a target-and-preserve prompt

For a wardrobe edit, write: replace the checked shirt with the black jacket in the reference; retain the face, body movement, camera and room. Avoid a simultaneous request for a new pose or location.

Give references a single role

A jacket photo should guide the jacket, not the person or camera. Name the relevant image when adding several references, and remove references that disagree with the requested change.

How to edit a video with AI

From a specific request to a usable clip

Separate an outfit change from a camera move or a new setting so you can judge each result.

Step 01

Choose the test segment

Find a short continuous passage that includes the difficult motion, such as a turn or an object passing in front of the target. Keep your original file for comparison.

Step 02

Specify a visible change

Identify the target by its position or appearance, then state the replacement and two or three details to retain. For several similar objects, describe exactly which one should change.

Step 03

Check the inputs and estimate

Upload the clip and any appearance reference. Select a model that accepts the source and a supported resolution. Review the credit estimate; a higher resolution does not solve an unclear instruction.

Step 04

Compare matching moments

Watch source and edit at the opening, midpoint and ending. Then play the whole result and listen to its sound. Save the prompt with the version; revise one instruction if you need another attempt.

Compare three focused edits

Use these comparisons to practise spotting changes outside the target before editing your own footage.

Change an outfit

Inspect the neckline, sleeves and clothing during movement.

Replace the clothing with the matte black techwear jacket shown in the reference image.

Review and refine

When the edit misses the target

Check the beginning, middle and end, then play the full clip for flicker, shape changes and sound.

The subject changes too much
Reduce the edit to one attribute and name essential identity or geometry details.
Face, hands, silhouette and the target’s outline during turns.
Flicker or drifting objects
Try a clearer source segment and remove conflicting references or complex texture requests.
The moment the object becomes hidden, reappears or crosses the frame.
Background edges look wrong
Specify the setting and light direction; avoid asking to change the camera at the same time.
Hair edges, transparent objects, reflections and contact shadows.
Questions

Questions

Which video files can I upload?

Upload one MP4 or MOV up to 200 MB. The default accepts 2–30 seconds. Duration, dimension and reference limits depend on your selected model; check the uploader’s requirements.

Can I choose length and aspect ratio?

This editing mode follows the source clip rather than offering a separate output length or canvas. Choose the available resolution; prepare a different crop or trimmed source before uploading when needed.

How is this different from Video to Video?

Use this editor for a specific change within an existing shot. Video to Video is the starting point for an overall visual restyle. Neither tool replaces a timeline editor for trimming and assembling a full production.

Change the detail. Keep the shot in view.
