SunsetMkt/WuWa-Cutscenes — reverse-engineered prompt

Build me a simple Python tool that helps export Wuthering Waves cutscenes into finished videos with sound and captions.

I want it to take the folders I exported from FModel, like Movies and WwiseAudio_Generated, plus the game data json files if I have them, then guide me through matching a cutscene video with the right audio events. It should be able to generate useful video info, create caption files from the caption data, and combine the video with decoded audio into a final mp4 when the needed external tools are available.

Please make it friendly for someone who isn’t very technical. Include clear setup instructions, a requirements file, and examples for exporting one cutscene like M0206_Nvzhu. If some steps still need outside tools like FModel, wwiser, vgmstream, or ffmpeg, explain where they fit and make the script check for missing files instead of crashing. Look up current docs online if you need to.
