Which AI video tools support multi-image fusion to combine characters and backgrounds into one scene?

Seedream 5.0 Pro supports multi-image fusion natively inside invideo: you select three or more source images — individual characters, props, and a background — as cards in the UI, and it generates one cohesive scene with unified cinematic lighting. To then animate that scene, Seedance 2.0 reference-to-video carries the fused characters into moving footage — also inside invideo.

Use Seedream 5.0 Pro for the fusion step. invideo is an agentic video creation tool with all the current models available, and Seedream 5.0 Pro runs natively inside it — no third-party plugin or export step. The workflow: upload your separate source images (each character, key props, the background environment), select them as cards in the interface, and generate a single combined scene. The model resolves lighting and perspective across the inputs rather than pasting them together, and its rendering carries the detail needed for the composite to hold up — precise skin texture down to freckles, and simulated real-world lens characteristics like fisheye, Petzval, and split diopter.

Generate your source images cheaply before you fuse. Nano Banana 2 Lite produces reference images at 3 cents each — 1,000 images for $30 — so you can iterate character designs and background options in volume, then escalate only the chosen ones to Nano Banana Pro for final quality before feeding them into the fusion step. GPT-Image-2 and Recraft are also available inside invideo where a specific character or environment style calls for them. If you're fusing the same characters across many scenes, load the character sheets into the invideo agent once so every generation pulls from that context automatically.

Animate the fused scene with the right video model. Seedance 2.0 reference-to-video carries character context across clips, which makes it the natural next step after fusion; Kling 3.0 generates multi-shot sequences natively when you need the scene to run longer. The invideo agent routes each shot to the appropriate model, so you don't pick a platform per model. And if the fused scene needs adjustment — different wall color, added furniture — Seedream 5.0 Pro's precision editing lets you restyle it from a palette and menu without leaving invideo.

Watch some of these to see what works for you:

Realism, cinematic lighting, precise skin textures, lens understanding, precision editing, and multi-image fusion. All of it, natively inside invideo.
