Codex image generation + free LTX-2.5 video generation, Claude Opus 5.5 fully automatically edits a 1-minute emotional short drama 'The Stopped Watch'

Course Introduction
An old watch that had stopped for many years, an experienced watch repairman, and one line: "Dad, it's running again."
This 1-minute emotional short drama 'The Stopped Watch', from script, first frame, video to editing, is completed entirely with AI collaboration:

✅ Claude Opus 5.5 writes the script, storyboard and video prompts with voice tags
✅ Codex (GPT) generates character reference photos and first frames for 7 shots according to the prompts
✅ Local free open-source model LTX-2.5 generates videos with dialogue and sound effects (21:9 · 480P)
✅ Claude automatically arranges tracks, separates audio, adds music, adds subtitles and exports the final cut in the AI Zhuiguang editing desk
✅ The two AIs communicate through a message board in the same folder, checking each other's messages once per minute

The first half of the video also demonstrates in detail how to install the Zhuiguang local engine with one click: 3 image generation models (FLUX.2, Z-Image, MOSS-Image) + LTX-2.5 video model + Zhuiguang agent, using your own graphics card to generate images, edit images and make videos for free.
Test configuration: 8G VRAM N card + 64G RAM; only supports Windows and N cards, it is recommended to reserve more than 100G of space on the D drive.
