Validated end-to-end on beauty-by-earth/video-01-three-product-grwm. Final master: finals/master-v12-captions-music.mp4 (~56s, 9:16 1080p, 3 product scenes + hook + endcard, total spend ~$30 for hero-quality 1080p output).

Purpose

Produce a 15-60s vertical 9:16 UGC review ad where an AI avatar talks to camera about 1-N products, using Seedance 2.0 reference-to-video on FAL. Avatar generation via NB2 (fal-ai/nano-banana-2/edit). Scenes are stitched with an L-cut HTML endcard, then sweetened with DIY karaoke captions + ElevenLabs music bed.

The architectural win: Seedance 2.0 reference-to-video generates lip-synced dialogue natively when generate_audio: true. No separate ElevenLabs VO + Whisper-locked beat manifest + Soul ID needed. Multi-shot internal cuts (4 sub-scenes per 15s call) are handled by the model in a single render.
