AI video generation is becoming more powerful, and Higgsfield’s newly launched Genjutsu AI model is a great example. This model can smoothly replace a character or object in an existing video while preserving the original scene, camera movement and actions.
Instead of writing long, complicated prompts, you simply upload a reference video and an image of the character you want to use. Genjutsu then recreates the video using your reference character while maintaining the original motion.
The best part? You can currently try Genjutsu for free and generate videos up to 30 seconds long.
What Is Higgsfield Genjutsu?
Genjutsu is an AI video transformation model available through the Higgsfield platform. It can analyse the movement in a reference video and transfer that motion to a new character.
For example, if your reference video shows a person walking, dancing, acting or performing a cinematic action, you can replace that person with your chosen character while retaining the same performance.
You can use Genjutsu for:
- Character replacement
- Object replacement
- Motion transfer
- Cinematic AI scenes
- Social media videos
- Short films and advertisements
- Creative character transformations
The model is particularly useful when you already have the desired action in a video and do not want to describe every movement through a text prompt.
Genjutsu’s Two Main Features
1. Motion Transfer
Motion Transfer creates a new video by copying movements from your reference footage and applying them to your uploaded character.
Use this mode when you want to recreate the performance, actions or body movements of the original video with a completely different character.
2. Object Swap
Object Swap allows you to keep most of the original video unchanged while replacing a particular character or object.
This option is helpful when you like the existing scene but want to change one important element without rebuilding the entire video.
How to Use Higgsfield Genjutsu for Free
Step 1: Visit the Higgsfield Website
Search for Higgsfield AI on Google and open its official website.
Create an account or sign up using your Google account. During the onboarding process, the platform may ask a few questions about your interests and intended use. Answer them to complete your profile.
Once the setup is finished, accept the terms and continue to the main dashboard.
Step 2: Claim Your Free Generation
Higgsfield may display its available plans and offers after account creation. Look for the option that says:
“Higgsfield Genjutsu – Claim Free Generation”
Click on Claim Free Generation to open the Genjutsu workflow.
The free-generation offer and its limits may change over time, so check the latest conditions displayed on the platform.
Step 3: Choose Your Workflow
Select either:
- Motion Transfer to recreate the motion of your reference video with a new character.
- Object Swap to replace a character or object while keeping the rest of the video largely unchanged.
For a complete character transformation based on an existing performance, Motion Transfer is usually the most suitable option.
Step 4: Upload the Reference Video
Click on the media upload section and add your reference video.
According to the tested workflow, the supported video duration is between 4 and 30 seconds. The generated video can also be up to 30 seconds long, giving you more creative freedom than tools limited to very short clips.
For better results, use a reference video that has:
- A clearly visible subject
- Smooth and understandable movement
- Consistent lighting
- Minimal motion blur
- Limited obstruction of the character
- A stable or intentional camera movement
Step 5: Upload Your Character Reference
Next, upload an image of the character you want to place inside the video.
Choose a high-quality image in which the character is clearly visible. A clean reference with suitable lighting, a clear face and an angle that matches the video can improve character consistency.
Step 6: Select the Correct Settings
Make sure Higgsfield Genjutsu is selected as the model.
Choose 720p quality if you want to use the free-generation option. Selecting a higher resolution may remove the free-generation benefit and require credits or a paid plan.
Activate Use Free Generation. The required credits should then be replaced with a “Free” label.
The offer may be limited to one complimentary generation per eligible account.
Step 7: Add an Optional Prompt
Genjutsu can work without a detailed prompt because it uses your uploaded video as the main motion reference.
However, you can add a short prompt if you want to guide elements such as:
- Visual style
- Environment
- Lighting
- Character appearance
- Cinematic atmosphere
- Clothing or accessories
If your reference video and character image already contain everything you need, you can leave the prompt section empty and proceed directly with the motion transfer.
Step 8: Generate the Video
Review your uploaded files and settings, and then click Submit.
Generation time can vary depending on platform traffic. Some videos may be completed within approximately 10–15 minutes, while others may take longer during busy periods.
If the platform is experiencing heavy traffic, try generating your video late at night or early in the morning.
Step 9: Download the Final Result
Once the generation is complete, preview the video carefully.
If you are satisfied with the result, click the download option to save it. In the demonstrated free workflow, the downloaded video did not contain a watermark, although current export terms should always be checked on the platform.
Tips for Getting Better Results
To improve the quality of your Genjutsu videos:
- Use a sharp, high-resolution character reference.
- Select footage in which the original character is clearly visible.
- Avoid scenes with extreme motion blur or frequent obstructions.
- Match the character image’s angle and lighting to the reference footage.
- Begin with a short test clip before attempting a full 30-second video.
- Use simple backgrounds for your first experiment.
- Keep your prompt short and specific when additional guidance is required.
Complex scenes with several people, fast cuts or characters moving out of frame may be more difficult for the model to reproduce accurately.
Advantages of Higgsfield Genjutsu
Genjutsu offers several useful benefits:
- No complicated prompting is required
- Videos of up to 30 seconds are supported
- Character motion can be copied smoothly
- Existing characters or objects can be replaced
- 720p generation is available in the demonstrated free trial
- Downloaded results may be available without a watermark
- It can produce cinematic and realistic transformations
Current Limitations
The free offer may allow only one trial generation per eligible account. Generation can also take longer when the platform is experiencing high traffic.
Results depend heavily on the quality and compatibility of your reference files. Difficult poses, hidden body parts, rapid camera movements and complicated environments may cause visual inconsistencies.
Free access, resolution options, usage limits and watermark policies can change, so verify the latest information on Higgsfield before generating your video.
Final Thoughts
Higgsfield Genjutsu is an impressive tool for creators who want to transform existing footage without writing lengthy AI video prompts. By combining a reference video with a character image, you can produce a completely new video while preserving the original motion and performance.
The ability to experiment with videos up to 30 seconds makes it particularly useful for AI filmmakers, content creators, advertisers and social media users.
Although the free trial may be limited, Genjutsu is still worth testing if you want to explore character replacement, motion transfer or cinematic AI video creation.
