MOTION LAB · A smoother sense of motion

Motion Boost

Create the moments between frames with AI. Choose twice the frame rate or a steady 60 FPS, and let RIFE on your device rebuild the motion in your short clip.

A few things to know

Useful for short clips, animation and moving subjects. Results and processing speed depend on your content and device.

Download the model, keep the video local

Reading, decoding, inference and encoding run on your device. Model and runtime files come from public CDNs; a cached model can be reused.

More frames can still have artifacts

Fast movement, occlusion, small text and flashes may produce distortion. Scene cut protection reduces some artifacts. Preview your result before downloading.

GPU and video codec support required

Use a recent Chrome or Edge with WebGPU and WebCodecs, over HTTPS or on localhost. Unsupported browsers or GPUs display an explanation.

Why is this slower than a regular conversion?

Every new frame needs neural inference and re-encoding. Higher resolutions, fixed 60 FPS and longer clips require more work. Keep this page open while processing.

Does interpolation create slow motion or a longer clip?

No. New frames are placed on the original timeline, preserving speed and duration. Double FPS uses the detected average source rate; fixed 60 FPS gives a consistent output rate.

What if my audio codec is incompatible?

AAC / MP3 audio is copied; other codecs are decoded and converted to AAC where supported. If the browser cannot convert the soundtrack, turn off Keep sound and retry. Audio is never silently dropped.
