Components

Choose File > Settings and open Components. The Model list of the Interpolation section ends with Get more models, which opens it too.

Download fetches a RIFE model and checks the file. Remove deletes the model and its TensorRT engine. Cancel stops a download.

TensorRT needs an NVIDIA GPU with driver 525.60 or newer on Linux, or 527.41 or newer on Windows. Install (3.1 GB) downloads the NVIDIA libraries, and a model when none is installed.

Set Backend to tensorrt in the Interpolation section. The first run with a model shows Preparing TensorRT for first use while interpolini builds an engine for it. Remove deletes the libraries. Each engine stays until you remove its model.

Source sets which FFmpeg libraries interpolini uses. The bundled libraries come with the app. The system libraries are only an option on Linux. Choose folder takes the libraries of another FFmpeg build from a folder, and Source then shows custom.

The libraries must have the same version as the bundled ones. Restart applies the change. More about FFmpeg.
