Make web video silky smooth, up to 240 fps, 100% local
Most web video is 24, 30 or 60 fps, but your monitor refreshes at 120, 144 or even 240 Hz, so fast motion looks choppy. FrameBoost generates the missing in-between frames in real time, using optical flow on your GPU (WebGPU), so every refresh shows a new frame. 100% local: no uploads, no accounts, no tracking. Free compare mode to see the difference on any video. Works on YouTube and most HTML5 players.
FrameBoost is a Chrome extension that enhances web video playback by generating additional frames in real time, achieving up to 240 fps using optical flow technology. It operates locally without requiring uploads or accounts, and is compatible with YouTube and most HTML5 players.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
