Workflow Steps
Step 1 - Hero Visual (Image Node)
The single source image everything else derives from one branded hero shot (product + logo + headline + CTA), generated or uploaded once. Label "Hero Visual 1." This is the only node that feeds every branch below.
Step 2 - Recomposition Concept, per platform (Text-to-Text Node, Claude Sonnet 5)
One of these per target platform, each connected to Hero Visual 1. Prompt pattern:
"Recompose this image [Hero Visual 1] as [Platform Name] ([aspect ratio], [exact pixel dimensions]). Keep the same subject and style, but reframe naturally for the new aspect ratio do not just crop, actually reposition the subject to work in this format. Leave clear space for headline text."
Claude's output is a detailed written recomposition plan background handling, subject placement and scale, where UI elements (CTA button, contact info, icons) move to, and what stays visually consistent (lighting, color, style) rather than just the image itself. This is the step that makes the final output deliberate instead of a lucky prompt guess.
Step 3 - Generate the platform-specific image (Image Node, Nano Banana 2)
Connected to both Hero Visual 1 and that platform's Step 2 concept text. Nano Banana 2 renders the actual recomposed thumbnail following the written plan exactly — subject repositioned, background extended/adapted, layout elements relocated as specified.
Step 4 - Repeat Steps 2-3 per platform
Built out here for: YouTube Thumbnail (16:9, 1280×720), Instagram Feed Square (1:1, 1080×1080), Instagram Feed Portrait (4:5, 1080×1350) etc... same two-node pattern (concept → render) repeated for each additional format needed (Story/Reels 9:16, podcast cover, etc.)
Step 5 - Export
Pull the finished set one properly composed asset per platform, not a crop of the original.
