This workflow builds fast, client-ready casting previs for advertising in two passes: a photo-real still and a short motion test. In STEP 1 – PREVIS STILL FRAME, your talent headshot (LoadImage) is combined with a scene description to synthesize a single frame of the talent in context (e.g., tennis court, soda product). Prompt text from MarkdownNote and PrimitiveNode is merged with shot directions using StringConcatenate, and GeminiImage2Node performs image-to-image guided synthesis using the headshot and any optional product/environment references. The resulting frame is saved with SaveImage for quick side-by-side casting reviews.
STEP 2 – PREVIS VIDEO upgrades that still into a short motion clip. ImageBatchMulti assembles one or more selected stills into a batch, and KlingOmniProImageToVideoNode generates a quick image-to-video preview—ideal for validating basic motion like a gentle dolly-in, a sip, and a look-to-can. SaveVideo writes the final clip to disk. Because the video is derived from your approved still, character identity and wardrobe cues tend to remain consistent across frames, making it well-suited for talent casting, pitch decks, and early client sign-off.
