Higgsfield Genjutsu tutorial: from sign-in to your first recast

What you need before you start

• A Google account. Sign-in is the only account step, and it is free.
• A source clip between 3 and 30 seconds: one clean take, one clearly visible subject, steady camera. Phone footage is fine - vertical included.
• Three to six reference images per element you want to change. One full body, one close-up, one detail shot works better than six near-identical photos.
• One sentence in your head: what changes, and what must stay.
• An active plan for rendering. The pricing page shows the tiers, starting with Lite; browsing examples and prompts costs nothing.

Step 1 - sign in and open the generator

The act buttons across the site open Google sign-in. Once you are in, the generator sits on the homepage - the same place where the example gallery and the technique breakdowns live, so you can study a source-and-recast pair right above the upload box.

Nothing is consumed until a render starts. You can open the workspace, upload a clip and look at what a run would cost before you commit to anything.

Step 2 - upload your source clip

• Trim before uploading. The model takes 3 to 30 seconds of continuous footage; a cut sequence has no single motion to transfer.
• Pick the shot where the subject is clearly visible and the camera does one thing - a push-in, a pan, a handheld follow.
• Skip shaky or heavily obscured footage. Recasts fall apart when the original is hard to read.
• Shorter is not just safer, it is cheaper: around 3 to 6 seconds is the most predictable length for a first run.

Step 3 - attach your reference images

• Attach 3 to 6 images per element: face, wardrobe, product, location. Up to 40 images per project in total.
• Keep references consistent with each other. Mixed lighting and angles degrade the face first.
• Mind the order. References are addressed by number in the prompt - "the woman in image 1" - so upload your lead first.
• Use clean, well-lit images. A screenshot of a screenshot gives the model almost nothing to work from.

Step 4 - choose Motion Transfer or Object Swap

Use Motion Transfer when the whole scene should be restaged: new cast, new location, new look, same performance. The motion, the camera and the timing come from your clip; everything visible is rebuilt from your references.

Use Object Swap when one element is wrong and the rest of the shot is approved - a jacket, a product in a hand, a single background detail. It changes that element and preserves everything else.

Step 5 - write the prompt and generate

• Follow the three-part formula: what changes, which reference to use, what must stay.
• Keep it to one or two sentences. Long cinematic paragraphs dilute the reference images instead of helping them.
• Do not describe the camera move or the motion. Your clip already defines both.
• Check the credit cost shown for the run, then confirm. Credits are only spent when the render actually starts.

Your first review: keep it, fix it or rerun it

• Watch identity first. Does the face hold across the whole clip, or drift when the angle changes?
• Check hands, edges and anything that passed behind the subject. That is where artifacts surface first.
• Read the label. Small text and logos can be regenerated imperfectly - verify anything legally load bearing.
• If the result is close, change one variable and run again. If it is wrong in kind, fix the references before spending another credit.
