Use Motion Transfer and Object Swap in the Video Generation node to edit a video using its existing footage as a guide. Motion Transfer reuses the source movement while changing most of the visual scene. Object Swap keeps most of the original footage while changing a selected part.

Choose a Mode

Choose the mode based on how much of the footage you want to change. Motion Transfer carries over the source movement and camera work into a substantially new visual scene. Object Swap is for changing one part while keeping most of the original shot.

Motion Transfer

Choose [Motion Transfer] when you want to keep a source performance, movement, or camera move while changing most of the visual footage, such as replacing the subject and setting with a new scene. It works well for carrying a dance, gesture, or other clear movement into a substantially different look.

Genjutsu

Genjutsu requires a source video and at least one image reference. Add up to eight reference images to guide the new subject or setting.

Kling 3.0 Pro & Standard

Kling requires a source video and one image reference. It works best when a person and face are clearly visible and large enough to see in the source video. If the person is far away or appears too small, generation may fail. If the action, pacing, or shot sequence itself needs to change, Motion Transfer may not be the right fit; use a source video with the movement you want.

When you select Kling 3.0 Pro or Standard, these additional controls appear:

SettingOptionsWhat it does
Character Orientation[Match Video], [Match Image]Sets whether the generated character's orientation follows the source video or the image reference.
Keep Original Sound[Yes], [No]Chooses whether to keep the source video's original sound in the output.

Object Swap

Choose [Object Swap] when most of the original footage is already right and you want to change only one part, such as a product, prop, outfit, or character. The goal is to retain the rest of the shot, including its movement, timing, and setting. Keep the edit localized: identify the element to replace and describe the replacement clearly. Reference images can help guide its appearance. Object Swap uses Genjutsu.

Choose an element that can fit the original shot's movement, perspective, and lighting. Large differences in size or shape, new interactions, or changes to several parts of the scene may be difficult to fit into the existing footage. Review the whole clip, especially moments when the element is partly hidden, because generated results can vary.

Choose Motion Transfer when you want to reuse the source video's movement and camera work while changing most of the visual scene, such as the subject or setting. Choose Object Swap when you want to keep most of the original footage and change only a specific part, such as a product, prop, outfit, or character.

Object Swap uses Genjutsu. Motion Transfer is available with Genjutsu and Kling 3.0 Pro or Standard. The models shown in the node are the current source of truth for availability.

You need a source video and at least one image reference. Genjutsu supports up to eight reference images, while Kling 3.0 Pro and Standard support one.

Use footage where the person's movement and face are clearly visible. If the person is far away or appears too small in the video, Kling Motion Transfer may fail to generate.

When you select a Kling 3.0 model, you can set Character Orientation to [Match Video] or [Match Image], and Keep Original Sound to [Yes] or [No].

The source video is required. Image references are optional, but can help guide the appearance of the replacement. Describe which object or subject should change and what should replace it.

Yes. You can use an existing video as the source. The video does not need to have been generated with AI.

Object Swap is designed to preserve most of the source footage outside the changed element, but results can vary. Motion Transfer uses the source movement to generate a new scene, so more of the visual footage can change. Review the full clip, including moments when the subject is partly hidden.

These modes are best for transferring existing movement or changing a localized element. A different action, duration, pacing, or sequence of shots may require a different source video or a new generation.
