AI upscaled to 4k from a quality 1080p source, then re-encoded, increasing framerate from 24fps to 60fps using TensorRT rife v4.6
English Subs

TensorRT RIFE motion interpolation is a combination of TensorRT and RIFE that enables real-time video frame interpolation with high quality. It is a TensorRT plugin for Vapoursynth, a video processing framework, that can be used for both transcoding and real-time playback modes. The interpolation quality, performance, and memory usage are determined by the AI model used. Model 4.6 provides higher quality but is slower than model 4.4, which requires less memory.

The frame rate of a film is the number of still images that are displayed per second to create the illusion of motion. The higher the frame rate, the smoother the playback, and the more realistic the motion appears. Here are some differences between 24, 30, 48, 60, and 120 FPS in movies:

24 FPS: This is the standard frame rate for movies. It is good for creating a cinematic experience and is not suitable for gaming. However, it can appear choppy during fast-paced action scenes.

30 FPS: This frame rate is commonly used in television broadcasts and is suitable for creating a smooth and natural-looking video.

48 FPS: This frame rate is used in some movies to create a more immersive and realistic experience. It provides smoother playback and is ideal for action-packed scenes.

60 FPS: This is the standard frame rate for video playback and has been the standard for more than 30 years. It provides a smooth and comfortable viewing experience.

90 FPS: This frame rate is not commonly used in movies or television. It is mostly used in gaming to provide a more immersive experience.

Please note that higher frame rates require more processing power and storage space. Also, the choice of frame rate depends on the type of content and the desired viewing experience.
