Hey Product Hunt 👋 Most web video is 24, 30 or 60 fps, but a lot of monitors refresh at 120, 144 or even 240 Hz. That mismatch is why panning shots and fast motion look choppy, even on a great display I built FrameBoost to fix that: it creates the missing in-between frames in real time, so every refresh of your screen shows a new frame (24 → 240 fps, 30 → 144 fps, 60 → 120 fps) How it works: Optical flow runs on your GPU via WebGPU to estimate how every part of the picture moves New frames are generated and shown at your display's refresh rate Scene cuts, frame edges and occlusions are detected to limit artifacts Privacy was a priority from day one: everything runs locally on your graphics card. No video is uploaded or re-encoded, no accounts, no tracking Try it: Compare mode is free: original on the left, interpolated on the right, on any video, so you can judge the difference before deciding Full mode gives you smooth playback on the whole video, unlocked once per device from the popup Alt+Shift+F toggles it, and it works on YouTube and most sites with a standard HTML5 player Good to know: You need a Chromium browser (121+) with hardware acceleration, and a display faster than the video (120/144/240 Hz) DRM streaming services (Netflix, Disney+, Prime Video) can't be processed, because the browser doesn't let extensions read their frames It's an early version and an independent project, so I'd love your feedback: which sites don't work for you, how it runs on your GPU, and what to improve first. Better quality on fast motion and lower GPU usage are next on my list Thanks for checking it out!
