NVIDIA's GPU-accelerated frame interpolation support has been integrated into FFmpeg through a Vulkan API, as announced by the project's developers. FFmpeg is a widely used software suite that powers much of the world's modern multimedia processing, including platforms like You Tube and many other services and applications. This tool now leverages NVIDIA Ge Force RTX GPUs to predict and generate the next frame without involving the traditional graphics rendering pipeline.

NVIDIA is extending this capability to video encoding, allowing users to increase the frame rate of their videos through frame generation technology. The Optical Flow Accelerator (NVOFA) in NVIDIA GPUs applies the same Optical Flow logic used in graphics rendering to videos, predicting the next frame and enhancing frame rates through AI-generated frames. NVIDIA calls this process Engine-assisted Frame-rate Up Conversion (FRUC).

FRUC is more than a conventional frame-smoothing algorithm, as it uses NVIDIA's dedicated Optical Flow Accelerator to calculate motion between consecutive source frames. NVENC provides the encoder-side frame data, while the optical flow hardware generates motion vectors that describe how objects move between frames. FFmpeg can then use that motion information to synthesize an intermediate frame, effectively increasing the video's frame rate without re-rendering the original content.

This is also more efficient than software-based interpolation, which can place significantly higher computational demands on the CPU. The new Vulkan implementation gives FFmpeg direct access to the NVIDIA hardware while avoiding the proprietary software dependency that prevented the earlier 2023 patch from being merged. The Optical Flow Accelerator was originally introduced during the era of NVIDIA's Ge Force RTX 20-Series "Turing." However, this Vulkan API-based implementation officially supports only NVIDIA's Ge Force RTX 30-Series "Ampere" and newer.

This means that owners of the Ge Force RTX 30, RTX 40, and RTX 50 series can benefit from the new feature. Video frame rates will now be doubled, allowing 30 FPS videos to be displayed at 60 FPS, and cinematic 24 FPS videos to be shown at 48 FPS with GPU-assisted frame interpolation. To take advantage of this, you simply need to run the FFmpeg tool on your end.
