This Higgsfield blog post of 13 October 2026 shows how to keep two characters from blending in one AI video scene. Give each character its own Soul 2.0 reference sheet and attach both in Cinema Studio 4.0. The scene prompt gets a reference block plus count, scale and position locks, with both heights fixed (163 cm and 125 cm). For returning characters, Soul ID and Elements are used, one Soul ID per character. At 12 credits per second in 1080p, the whole 60-second example film costs about 726.5 credits, or $36.34.

What is said

★ — how much it matters to the source.

  • ★★★ To keep two AI characters from blending, Higgsfield's blog advises giving each its own reference sheet named in the prompt: generate each sheet in Soul 2.0 and attach both as references in Cinema Studio 4.0; Soul ID and Elements carry recurring characters across projects. · character sheet, Soul 2.0, Cinema Studio 4.0, Soul ID, Elements
  • ★★ Higgsfield's blog says that when a scene adds a second person the model usually gets one weak input (a text description of both, one image with both faces, or a reference for only one), so the two identities share one anchor and their features can mix. · character drift
  • ★★ In a two-character scene, hair, outfits or props can move from one character to the other between shots, which Higgsfield's blog calls swapping. · character drift
  • ★★ Higgsfield's blog warns that a multi-view character reference sheet can be copied literally, so the same character appears twice in the scene. · character sheet
  • ★★ In two-character scenes a child and a teenager can end up the same height or trade heights between shots, which Higgsfield's blog calls scale drift.
  • ★★★ Higgsfield's blog gives four routes to a two-character scene chosen by the starting point: Genjutsu Motion transfer for an existing performance, Genjutsu Objects swap for a finished clip, Cinema Studio 4.0 with separate references for your own scene, Soul ID with Elements for returning characters. · Genjutsu, Cinema Studio 4.0, Soul ID, Elements, motion transfer, Object Swap
  • ★★ Cinema Studio 4.0 takes up to 50 references per generation and generates multi-shot clips up to 30 seconds with native audio; Genjutsu keeps the motion of an existing clip and changes who or what is in it. · Cinema Studio 4.0, native audio, Genjutsu
  • ★★ To keep two similar characters apart, Higgsfield's blog writes into the sheet prompts what separates them: age markers, build, height and wardrobe palettes that do not overlap (mustard and denim for one sibling, purple and cream for the other). · character sheet
  • ★★ Higgsfield's blog makes one 16:9 Soul 2.0 sheet per character in a three-panel layout: full-body rear view, a large frontal face close-up with the full hair silhouette, and a full-body front view, in the same outfit on a clean background. · character sheet, Soul 2.0
  • ★★ Animal characters in a two-character scene (a black panther and a capuchin monkey) get sheets in the same three-panel format so they stay consistent next to the main characters. · character sheet
  • ★★ Higgsfield's blog advises a separate reference for any important prop or location that must stay the same across shots; a prop seen in every scene gets a prompt that fixes its exact size, materials and a single button colour.
  • ★★ Higgsfield's blog generates each location empty in Soul 2.0 at 16:9, with a fixed three-quarter camera and a clear open area for the characters, and excludes people and animals so a location reference never adds an extra figure. · Soul 2.0, location reference sheet
  • ★★★ Higgsfield's blog structures a two-character scene prompt as a reference block (one line per reference with name, age, height, traits and an instruction to keep its identity), a count lock, a scale lock, a position lock, timed shots, quoted dialogue with voices, and locations as geography only.
  • ★★ Higgsfield's blog adds a count lock to a two-character prompt ("Show one Jerry and one Lucy") plus a line that the character sheets carry identity only, so their three panels never become three copies of a character. · character sheet
  • ★★★ To keep two characters at the right relative size, Higgsfield's blog fixes both heights in the prompt (163 cm and 125 cm) and the ratio between them, with the younger one about 77% of the older one's height.
  • ★★ Higgsfield's blog adds a position lock: the first frame puts each character on a fixed side of the screen, and hands stay consistent, such as a remote always in the same character's right hand.
  • ★★ Higgsfield's blog asks for new camera positions in each location line, so the location image sets the layout of the space and never becomes the opening frame. · location reference sheet
  • ★★ In Cinema Studio 4.0 (Cinema Studio, Video), add the scene's character, prop and location references, paste the prompt, set the look in the Director's Panel (Film setup, Camera, Color palette, Lighting), then 16:9, the scene duration and sound on. · Cinema Studio 4.0
  • ★★ Before generating, check that every tag in the prompt's reference block matches an attached image, and reuse the same character and prop references for every scene so the cast stays consistent. · Cinema Studio 4.0, character sheet
  • ★★★ Cinema Studio 4.0 at 1080p costs 12 credits per second, so an 18-second scene costs 216 credits and a 60-second film 720 (prices checked 12 October 2026). · Cinema Studio 4.0, credit
  • ★★ The same two-character reference setup works in Seedance 2.5 on its own, with the images added under References. · Seedance 2.5
  • ★★ Higgsfield's blog advises reviewing every clip against the character sheets before generating the next scene: a close-up against the sheet's centre panel, no traded hair, clothing colours or props, the height difference in wide shots, one of each character. · character sheet
  • ★★ Higgsfield's blog says most consistency problems in a clip show up around the 5 to 8 second mark, so each clip should be watched to the end. · character drift
  • ★★ When a two-character clip is off, Higgsfield's blog advises changing one thing per retry, the prompt or a reference, never both at once.
  • ★★ To bring two characters back across a series, Higgsfield's blog advises training a Soul ID for each in Soul → Train new character on 20 to 80 images; trained characters appear in Elements automatically, and props and locations are saved as Elements from Assets. · Soul ID, Elements
  • ★★★ A Soul ID represents one identity, so for scenes with two or more recurring characters Higgsfield's blog advises one Soul ID per character used through Elements, where each person, location and prop is made once and pulled into any shot by name. · Soul ID, Elements
  • ★★ In Cinema Studio 4.0 or Seedance 2.5, typing @ in the prompt field picks characters, props and locations saved as Elements by name. · Elements, Cinema Studio 4.0, Seedance 2.5
  • ★★ When a two-person performance already exists, such as one you filmed yourself, Higgsfield's blog advises Genjutsu Motion transfer so your two characters repeat it. · Genjutsu, motion transfer
  • ★★ Genjutsu Motion transfer (Video → Genjutsu) takes a reference video of 4 to 30 seconds and up to 30 character images, such as character sheets, and generates at 480p, 720p or 1080p. · Genjutsu, motion transfer, AI Influencer Studio, character sheet
  • ★★ When a two-character scene is finished and only one character needs to change (a drifted face, a variant, a recast for another market), Higgsfield's blog advises Genjutsu Objects swap with reference images of the new character; the rest of the frame stays as it was. · Genjutsu, Object Swap
  • ★★ Higgsfield's blog costs two props made with GPT Image 2.5 Sunburst at 5.5 credits, 2.75 per image (checked 12 October 2026). · GPT Image 2.5, credit
  • ★★★ Higgsfield's blog puts the whole two-character workflow for a 60-second film (four sheets, two props, four locations, five scenes) at about 726.5 credits, $36.34 at 20 credits per $1. · credit
  • ★★ Cinema Studio 4.0, Seedance 2.5 and Genjutsu are on the Plus ($49 a month) and Ultra ($129) plans; Starter ($15) includes Seedance 2.0 Fast and Mini, and plan details can differ by region (checked 12 October 2026). · Cinema Studio 4.0, Seedance 2.5, Genjutsu, Plus plan, Ultra plan, Starter plan, Seedance 2.0
  • ★★ Higgsfield's blog says two-character scenes are easier to control than larger casts: as more recurring characters share the frame, identities, wardrobe and proportions get harder to keep apart even with individual references.
  • ★★ Even with separate references, extreme angles or heavy style shifts can still change details of a character, Higgsfield's blog says. · character drift
  • ★★ Genjutsu Motion transfer and Objects swap do not take trained Soul ID characters directly; Higgsfield's blog advises character sheet images or AI Influencer characters instead. · Genjutsu, Soul ID, Object Swap, motion transfer, AI Influencer Studio, character sheet
  • ★ Higgsfield's blog advises using only reference footage and faces you own or have permission to use.
