I was just poking around, but how/why aren't there issues with the videos now. Sure you're just embedding youtube videos, but what's to stop them from taking that down?

Are there really no open licensed workout-movement animations out there? That sounds like a fun beginner animation project honestly.

The videos currently embedded are "watermarked" and come from a partner app that granted permission to use them for this open-source project.

I wanted to make sure everything is legally safe and not just scraped or reused without rights.

Producing proper 3D exercise videos is actually VERY expensive we’re talking €10–20 per animation, or thousands of euros per month if you go through a good/high quality API provider. That’s why it's such a tough space for open-source tools to compete in.

Long-term, I'd love to help build a community-driven, open-licensed library of movement animations but until then, this partnership was the best balance between cost, legality, and quality.

Thanks for raising it
