Redditor seeks open-source VLM to reverse-engineer cinematic prompts from stills, says ChatGPT falls short

A filmmaker is looking for an open-source vision-language model that can analyze a reference image and generate a highly detailed, technically accurate prompt to recreate the same cinematic frame — not a generic image caption. ChatGPT's attempts were too generic for his needs.

He needs the model to capture camera angle, shot size, framing and composition, lens characteristics and depth of field, lighting direction, contrast and color grading, plus character positioning and spatial relationships — essentially a cinematographer breaking down a film still into a prompt for his AI workflow.

He's asking for recommendations of open-source models, ComfyUI nodes or custom workflows that can run locally, ideally from people who have tested them for cinematic reconstruction rather than general captioning.
