Turn any video into a buttery-smooth high-frame-rate copy, entirely offline on your NVIDIA GPU. Pick a file, choose a target frame rate (2x, 4x, 8x and up, or match your monitor) and click Smooth It!
Five interpolation models: GMFSS (best for anime), RIFE (best for live action) with a DRBA option that preserves anime pacing, NVIDIA DLSS 4.5 Frame Generation, Nvidia Smooth Motion, and SVP's svpflow engine. The same render can AI-upscale to 16K (RTX Video Super Resolution + Real-ESRGAN restore), sharpen, and convert SDR to real HDR10 with proper mastering metadata, plus optional Dolby Vision 8.1 and HDR10+ export.
Original frames pass through untouched; output is 10-bit visually lossless HEVC, AV1 or H.266 with every audio track, subtitle, chapter and font preserved. Pause anytime or close the app - renders resume where they left off. One self-contained zip: no Python, no ffmpeg, no cloud, no account. Free, MIT licensed.
