Changing characters in videos seems simple but there are several factors to consider. From the movement, camera, timing, lighting and environment, it can be challenging to change the subject without affecting these elements using traditional editing software.

With AI Video Transformation, creators can take their existing video and add new characters, products, outfits and visual elements. The aim of Xelta Bankai is to transform the visuals of a video whilst keeping the original movement, camera path and timing.

Using AI Video Transformation will allow creators to transform their existing videos. By using reference videos and images, creators can change the visual subject of their videos. This can be great for creative experimentation, changing characters, adding products and alternative video ideas.
Why Changing a Character in an Existing Video Can Be More Complex
Imagine you have a video of someone walking in a modern city and wish to change the character.

Using traditional editing tools this could involve:
Removing the original subject from the video.
Creating or adding in a new character.
Positioning and sizing the character.
Creating new movements and expressions.
Adjusting the lighting, shadows and perspective.

Review each frame of the video.
The challenge comes from ensuring the video is changed throughout.
If the original character turns around, lifts an arm or walks behind an object, the new character should follow the same visual pattern.

This is where motion aware AI Video Transformation can help.
What is AI Video Transformation?
AI Video Transformation is a technique to change specific visual elements of existing videos using AI.
Depending on the workflow, creators can add new characters, products, outfits and scenes.
However, there will be a difference between creating a new video and transforming an existing one.
Traditional Video Creation AI Video Transformation
Often starts from a new video or set up. Starts from an existing reference video.
Needs to recreate the scene. Uses the original scene.
May need to recreate movements. Uses the original movement.

Ensure you have a reference image with a clear face, visible clothes and appropriate pose.

Many fashion related content will require several visual changes. Using Bankai you can experiment with changing outfits without having to recreate the entire movement.
This can be useful for:
Fashion concept videos.
Creative outfit ideas.
Character styling.
Alternative costume ideas.
Ensure the clothing looks consistent, fabric and movement of clothing is correct.
3. Change Products/Scenes
You can also use existing videos as a starting point for alternative visuals.

Ensure your video has:
Clear main subject.
Sufficient lighting.
Easy to understand body movement.
Reasonably consistent camera.

When changing characters ensure:

Where Can You Use AI Video Transformation?
Often the best use cases will be when you have the correct movement in your video but want to change the visuals.
Social Media Content
Experiment with changing characters, outfits and visuals using your existing video.
Fashion & Apparel
Experiment with different styling ideas using your existing movement.
Entertainment/Filming
Experiment with different character designs, visuals and scenes.
Advertising/Product

What Can Impact the Quality of an AI Video Transformation?
Whilst AI Video Transformation will help reduce some of the editing required, there are still some considerations.
Consider:
Issue Consider
Inconsistent character Ensure the subject looks consistent throughout.
Face Ensure the face has detail.
Hands/Limbs/Complex Movements Ensure these are not distorted.
Lighting Ensure shadows and highlights match the original.
Clothing Ensure patterns, textures and detail are correct.
Background Ensure there are no unexpected changes.
Why Reference Quality Matters
If your reference image is blurry then it can be difficult to get the correct details.
If your video has quick movements, partially obstructed subjects and complex camera movements then this can create some issues.
Ensure you start with clear videos and a good reference image. Only make one meaningful change at once.
Always review your AI generated video.
This is especially important if recognisable people, branded products, logos, claims and commercial messages are included.
Ensure you have permission to use the source video and reference images. Ensure the final output looks correct.
Why Would You Want to Use a Video Transformation Workflow?
Not all creative projects will require a brand new video.
Sometimes you will have the correct camera movement, timing and composition in your video. All you need to do is change the visual subject.
This is where video transformation workflows can help.
Rather than recreating everything, you can use the existing video as a base. This can help you experiment with different visuals.
With Xelta you can also experiment with the wider AI Video Generation workflow.
Depending on your project:
Use video transformation if you want to keep the original movement and scene.
Use text to video if you want a brand new scene.
Use image to video if you have a visual reference.
These workflows will help solve different creative issues. Choosing the correct starting point can help avoid unnecessary iterations.
