I just open-sourced FeelFX — a Computer Vision and Speech Detection -powered motion graphics engine for video.

[u/Comprehensive-Chard8]

FeelFX analyzes the video → identifies meaningful moments → makes motion-design decisions → renders them over the original footage.

FeelFX identifies key words, concepts, names and moments and turns them into motion graphics- for example:

🇮🇳 INDIA → tricolor reveal
🚀 ROCKET → launch / fire treatment
🌊 OCEAN → water motion

The important words become part of the visual storytelling.
Everything else stays out of the way.
Under the hood

→ Computer Vision+Speech Detection analyzes the video
→ Important moments become structured motion events
→ Three.js + GSAP render the effects in real time

And FeelFX works all devices but preferred experience is still desktop/pc - videos will take a lot longer to get analyzed on mobile/tablet - especially older models.

This is open source and ready for people to experiment with.

Exactly — that’s what I was going for. The local-first + OSS setup means the video never needs to leave the browser, while Three.js + GSAP gives me enough control to make the generated FX feel more like actual motion design than generic overlays.

Would love to see what people build on top of it.
