What's the best AI tool to generate a 4K multi-angle character reference sheet for film?

For 4K multi-angle character reference sheets in film, Nano Banana Pro is the strongest single model — it generates four-angle turnarounds plus face and mid-angle closeups at 4K max with high prompt adherence. Pair it with Recraft for photorealistic face portraits (pores, stubble, lines) and route both through the invideo agent so the sheet locks into context for every downstream shot.

Use Nano Banana Pro for the sheet itself. In documented productions it generated 360-degree turnarounds at 4K max with four angles plus face and mid-angle closeups, and it was chosen over Nano Banana 2 specifically for character work because of stronger prompt adherence on identity details. For the face portrait that anchors the sheet, generate it in Recraft V4 first — Recraft renders skin imperfections (pores, lines, stubble) that make AI faces read as real, then feed that portrait into Nano Banana Pro as the locked reference for the multi-angle pass.

invideo is an agentic video creation tool with every current image and video model — Recraft, Nano Banana Pro, GPT-Image-2, Veo, Kling, Seedance 2.0 — available inside one agent, so you don't pick a platform per model. Spin up a casting sub-agent, give it the character description, and have it run the same prompt on two image models in parallel (Nano Banana Pro and GPT-Image-2 is a strong pairing) so you can pick the aesthetic that lands. One production generated 11 reference images total — headshots and head-to-toe refs across four characters and one prop — and locked each character in about 5 generations at roughly $9.78 per character.

Generate four options per asset, not one. Across documented productions the workflow that worked was four variations per character sheet and per environment reference, pick the best, lock it before any video generation begins. Two specifics that materially change sheet quality: remove objects from the character's hands before the multi-angle pass (props in hand break consistency across turnaround angles), and include close-up panels for scars, accessories, and small details — wide-only sheets cause downstream video models to hallucinate the missing detail. For evolving looks across a sequence (costume changes, trinkets added beat by beat), generate a separate sheet per beat rather than one master sheet.

Once the sheet is locked, the same agent attaches it to every video generation. Route Seedance 2.0 reference-to-video for shots where the character must carry context across clips — it accepts the character sheet plus a location reference simultaneously, which produces better identity hold than start/end frame methods. Kling handles native multi-shot sequences from a single reference well; Veo is strong on photoreal motion. The invideo agent picks per shot. As Hridaye, invideo's creative director, puts it: "the AI always needs to see what the character is exactly, right? Or else it'll kind of hallucinate and imagine something that's under the cap. So, we don't want to do that. We always want the character to be seen as we see it on the character sheet."

One discipline worth keeping: if a continuity error shows up later in a shot, fix the panel in the character sheet rather than re-rolling the shot — the agent identifies which panel contains the error, corrects it there, stores the updated sheet, and every subsequent generation inherits the fix.

Watch some of these to see what works for you:
