A Higgsfield Genjutsu alternative for swapping the people in a video

If you want to replace the people in a video with AI and keep everything else, PrismPoster's Remake is a direct alternative to Higgsfield's Genjutsu: you bring a 3 to 30 second clip, pick up to 6 people in it, and choose who plays each one, and the moves, camera, setting and sound stay as they were. Genjutsu is the better pick when you want to steer a render with up to 30 reference images; to swap an object in PrismPoster, the Video Studio's change lane does it from one sentence. Below is what each tool states, side by side, and how to choose.

What is Higgsfield Genjutsu?

Genjutsu is Higgsfield's video-to-video tool, announced on the Higgsfield blog. It works from one input clip of 4 to 30 seconds and has two modes: Motion Transfer, which carries the clip's motion over to a new subject, and Object Swap, which replaces things in the clip. It takes up to 30 reference images and returns video at up to 1080p, priced by length and resolution, and its API docs state the source clip keeps its motion, camera, timing and audio. Higgsfield itself is a subscription suite: the free plan has no credits and watermarks every generation, and credit packs can only be bought on an active plan and expire 90 days after purchase, per its help center. Where Higgsfield's pages do not state something, the table below says so rather than guessing.

What is Remake?

Remake is a flow in PrismPoster's Video Studio for recasting the people in a short clip. You drop in the clip, choose which people to replace, and give each one a performer: a photo of yourself, a character you saved in Character Studio, a photo of someone who agreed to it, or a character you describe. Anyone you don't pick stays in the video as themselves. The viral video remake page shows a full example and the current prices, and how to remake a viral video with AI walks through it step by step.

When is Genjutsu the better pick?

Be fair to the tool you are leaving. Genjutsu is the better choice in three cases:

• You want to swap an object inside the same video-to-video run. Object Swap replaces things in the clip. Remake recasts people and leaves objects alone; in PrismPoster an object swap is a separate pass in the Video Studio's change lane, which changes one thing and keeps the clip's length, shape, camera and pace.
• You want to steer the result with many references. Genjutsu takes up to 30 reference images. Remake takes one performer per person, because the performer is the whole brief.
• You already subscribe to Higgsfield. If your other projects live there and a monthly plan with credits that reset each cycle suits you, staying in one place may matter more than any single feature.

When is Remake the better pick?

• The clip has several people and you only want to replace some of them. You pick who changes; everyone else stays as themselves.
• The sound matters. The clip's spoken words and music come through, so a dance trend keeps its song.
• Real people are involved. Remake asks you to confirm that everyone in the clip is an adult who agreed, and it declines children before anything is charged. Our guide to AI likeness consent explains why.
• You want to see it before you pay for the finish. A draft renders at lower quality and a lower price, so you can check the moves landed first.
• You don't want a subscription. PrismPoster sells one-off credit packs, and bought credits never expire.

How do you replace a person in a video with Remake?

1. Trim your clip to the move you want, 3 to 30 seconds.
2. Open Remake in the Video Studio and add the clip, confirming you have the right to use it.
3. Pick the people to replace and choose a performer for each.
4. Render the draft, check it, and finish the one that works.

Every file carries machine-readable AI provenance, and clips from a free account also show a small AI-generated label. Why AI video tools refuse real faces covers what gets declined and why.

Frequently Asked Questions

Is there a free Higgsfield Genjutsu alternative?

Making a PrismPoster account is free, and in many countries a new account gets starter credits with no card. Remake drafts are paid in credits by the rendered second, so check the starter credits against the draft price on the viral video remake page, which shows the current numbers.

Can I swap a character in a video with AI without a face swap?

Yes. Remake does not paste a face onto the original footage. It puts your performer, with their own look, in place of each person you pick, and keeps the moves, setting and sound from the clip.

How many people can Remake replace in one clip?

Up to 6, each with their own performer. Anyone you don't pick stays as themselves.

Does Genjutsu keep the original audio?

Yes. Genjutsu's API docs state the source clip keeps its motion, camera, timing and audio. Remake keeps the clip's spoken words and music too.

Is PrismPoster a Higgsfield alternative for more than video-to-video?

PrismPoster also makes images, video from a prompt or a photo, and music with vocals, and has a timeline editor that generates on its tracks. The PrismPoster vs Higgsfield page compares the two across all of it.
