This ComfyUI workflow builds advertising storyboards fast by turning a plain 6‑panel grid and a shot list into clean black‑and‑white sketch frames, then optionally upgrades those sketches into production‑quality styleframes. The STORYBOARD GENERATOR group takes your shot descriptions from INPUT SHOT LIST, merges them with consistent style instructions via StringConcatenate, and feeds them to either OpenAIGPTImage1 (OpenAI’s gpt‑image‑1) or GeminiImage2Node for image generation. The first image you load is used as the panel grid reference, guiding the model to sketch simple line drawings inside each box and place the shot description as a caption beneath each frame. BatchImagesNode handles all six shots in one go, and SaveImage writes the finished storyboard to disk. MarkdownNote nodes in the graph provide in‑canvas guidance, while PrimitiveNode values set defaults like monochrome line style and panel count.
