TL;DR

Gemma 4 31B expands a single-line idea into a 10-beat structure. HiDream generates 11 images at 2048², LTX-2 A2V/I2V renders 11 clips, Irodori-TTS handles dialogue and a male narrator, and ffmpeg burns in subtitles and a Hook title overlay — all fully automated. End-to-end: a 40-second portrait video (512×768) in 25–30 minutes. One local GPU (96 GB Blackwell), zero API cost.
