FavioVazquez/showtime ? reverse-engineered prompt

Build me a local video studio for a coding agent.

I want to type a simple request like, make a 20 second launch video for this repo, and have the agent figure out the rest, write the script, add voice over, music, captions, motion graphics, and export a finished video file on my machine. It should work fully locally, with no API keys, no uploads, and nothing sent to the cloud.

Make it feel like a real workflow, first show a quick preview or draft, then do the full render, then run a final quality check and save the output in its own folder so nothing gets overwritten. It should support a few different video types, like repo explainers, release videos, and simple promo videos. If needed, look up current docs online for any tools or libraries you use.
