cronux-ind/ai-video-generation-workflow — reverse-engineered prompt

Build me a simple app that helps someone make short finance explainer videos without using a video editor.

I want to paste or write a script, add slide images for each section, choose a voice, generate narration, create subtitles from the script, then render everything into an MP4. The app should guide me step by step so it feels easy for a non technical person. I should be able to preview or check the audio and subtitles, edit subtitle text or timing if needed, and save the finished video in an output folder.

Please make the workflow stable and modular, with clear folders for scripts, slides, settings, and finished videos. It should use FFmpeg for the final render and include sensible error messages if something is missing. Make it work well on Windows, and include a simple example project so I can test the whole process right away. Look up current docs online if you need to.
