The defining feature of DLSS 3 is AI frame-generation, the ability of NVIDIA GeForce RTX 40-series "Ada" GPUs to predict the next frame to one that's rendered by the GPU, and generate the frame without any involvement of the graphics rendering pipeline. NVIDIA is taking this concept to video encoding, too, letting you increase the frame-rate of your videos through the "magic" of frame generation. NVIDIA Ada GPUs' Optical Flow Accelerator (NVOFA) component can apply the same Optical Flow logic for videos as it does for graphics rendering, predict the next frame, and increase frame-rate through AI generation of that frame. NVIDIA refers to this as Engine-assisted Frame-rate Up Conversion (FRUC).

There's more to FRUC than the "smooth motion" features your TV comes with; NVENC compares two real frames from a video, determines motion vectors, and sets up an optical flow stage, so the generated frames that are interpolated with real frames are accurate. NVIDIA will be releasing FRUC as a library, so it can be integrated with popular content-creation and media-consumption applications on NVIDIA Ada GPUs. It allows people with Ada to create higher frame-rate videos; as well as those with Ada GPUs to consume media at higher frame-rates.A video presentation by NVIDIA on the video encoding features of Ada follows.
