I would bet I'm late to the party here but I just tried using Claude Opus 5.5 to make a promo video for my [open source project ](https://github.com/Mason-Levyy)that allows you to connect AI tools to MyFitnessPal. I was blown away by its ability to make a pretty solid promotional video and soundtrack just with a few iterations. This is using a remotion and a skill I generated using some articals and my own likes and dislikes. Has anyone else tried this use case, I think its super cool!
