AI frame interpolation turns any video into smooth 60 or 120fps, or into slow motion up to 8x. Everything runs on your device. One-time purchase, no subscription. Smooth out choppy video at 60 or 120fps, slow footage down without stutter, and strip the duplicate frames out of anime. New frames are generated by AI on the phone itself, not in the cloud. One-time purchase, subscription-free and ad-free. Slow motion that stays smooth Slow it down by up to 8x. Instead of repeating frames, the app generates the in-between frames, so motion stays fluid even at 8x.
