The Master Guide / 06 Anchors and stills · Stylised films (Seedream 5.0 Pro)
Seedream for stylised films
Seedream 5.0 Pro makes every still of a stylised film (decided). Nano Banana Pro keeps photoreal work, and GPT Image keeps cut-outs and graphics with text.
Seedream 5.0 Pro makes every still of a stylised film (decided). Nano Banana Pro keeps photoreal work, and GPT Image keeps cut-outs and graphics with text.
Use it when the film is stylised: 2D, anime, cartoon, illustration, a paper or clay look, painted 3D, 3D CG (computer graphics), or caricature in a real world. It makes the style anchor, each character's three-quarter design, turnaround, expression map, cast line-up and state sheets, the stylised location plates, props and products drawn in the style, the stylised storyboard and internal frames, and the correction passes on all of these.
Don't use it for:
photoreal faces, products, plates or frames, or edits of them (see Photoreal anchors (Nano Banana Pro));
transparent cut-outs: leave its background-removal option off, because GPT Image generates with transparency, and each job has one tool (see Still prompts, storyboard frames and diagrams → Transparent cut-outs);
any text that must read, and any label: labels follow Photoreal anchors (Nano Banana Pro) → Products and labels, words on screen are graphics built in finishing, and every staging map and position image, labelled or not, is GPT Image's (decided);
anything that needs 4K.
Why [proven]: it was the largest stills model in nine of the fourteen placing films of a judged festival on Seedance 2.5, six of them stylised. That count says which model they used, not how they used it. The method comes from the films that show it: one, FIX, shows its full sheet-and-plate method; Soulless, Morek and Lullaby show parts. The festival was Higgsfield's own, so the platform chose the winners, while the makers are independent.
Its limits, and the check for each
Limit | What it means | The check | What you do |
Faces sometimes widen [official guidance] | A drawn or caricatured face comes back broader than its design | Put every face crop beside the approved design, scaled to the same head height. Compare the head's width to its height, the eye spacing and the jaw (steps below) | Fail a wide face. Regenerate with the design attached, and add "do not widen his face" to the design lock (the list of facial structures that must match; see Stylised films (Seedream 5.0 Pro) → Settings and prompt style). Never stretch or squash the file |
Identity drifts between identical runs [official guidance] | The same prompt and references give a slightly different character or place each time | Check every new candidate from scratch beside the approved anchor. Never assume a re-run matches | Attach the approved anchors to every later still. Keep the approved file as the only source of that design: never regenerate it "to get it back" |
2K is the maximum [official guidance] | No 4K close-ups, label checks or 4K hero pages | Look at every full-bleed page image at page size, and check it is sharp | Use the 2K file, and plan nothing here that needs 4K |
No seed | No exact repeat | Record the prompt, references and settings of every image in your take log (see Planning, budgets and takes → Your take log) | Keep the approved file. Treat a remake as a new image and check it in full |
No 4:5 | A 4:5 feed version has no native frame | Look up the ratios your plan lists for the film (the shot plan; see Planning, budgets and takes) | Make the plate or frame at 3:4 with the action inside the 4:5 area. Then keep the full width and trim equal strips from the top and bottom until the frame is 4:5 (one sixteenth of the height in all) [best available, not yet validated] |
Drawn styles drift toward realistic halftone [official guidance] | Halftone dots creep in. Photographic skin or soft depth may follow (observed in use, not in the maker's notes) | Compare the line weight, shading steps and texture with the style anchor at 100% | Restate the style lock (the sentence that keeps every person, object and surface in the medium; see Stylised films (Seedream 5.0 Pro) → Settings and prompt style), re-attach the style anchor and regenerate |
Logos corrupt [official guidance] | A broken logo. Stray letters appear too (observed in use), though the maker claims good text | Check every image for letters, logos or text nobody asked for | Generate no text in Seedream. Readable words follow the routes under Don't use it for |
Do it yourself
Compare a face's width with its design (Photoshop or Affinity)
Put the face crop and the approved design's crop on one canvas.
Scale them to the same head height.
Compare the width with two vertical guides.
