# create-video-seedance-2-fal > ⚠️ **REQUIRED PREFLIGHT (2026-06-04): every Seedance prompt that names a branded product MUST be paired with a real reference image of that exact product** as one of the `--image-ref` inputs. Text-only product description without a ref invites Seedance to invent geometry that does not match the real SKU. If no reference exists locally, find one via brand-assets → existing-ads → PDP harvest → promote to `clients/<brand>/brand-assets/reference-photos/`. Optionally clean an occluded ref via a quick GPT-image-2 edit pass first. **Always get user review of the reference + final prompt before firing the paid call.** See `feedback_product_reference_required.md`. ## Purpose Wraps the FAL endpoint `bytedance/seedance-2.0/reference-to-video`. Pass 1-N image references (typically: portrait + product + optional setting) + a structured prompt → get back a 4-15s clip with native lip-synced VO and ambient audio. Seedance 2.0 renders **multiple internal cuts within a single 15s call** when the prompt specifies sub-scene structure (e.g. WIDE HOOK / PRODUCT HERO / SIDESTEP / REACTION). This is the architectural win over the older NB2 + i2v multi-keyframe approach — fewer calls, native lip-sync, no Soul ID required. Use this atom when: - The clip needs a talking-head avatar reviewing or demonstrating a product - Native lip-synced dialogue is required (set `--generate-audio`) - Identity must hold via image reference, not video reference (see Decision Rule 1) ...
