The Duellists

Ai upscaled from a 1080p bluray source, then increased framerate to 60fps via TensorRT Rife v4.9v2.

(Testing new rife model 4.9v2)

English audio and English subtitles included.

Upscaled as per request for Portica777



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, 60FPS 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.



We are no longer bound by the technological restrictions created by old, grainy, low frequency, and low frame rate cameras and TV's.



Early silent films had frame rates from 14 – 26 frames per second, which was enough to provide a sense of motion, but the motion was often jerky or uneven. You can imagine how film cranked by hand when photographed, and then cranked by hand again when projected, would make it nearly impossible to portray true-to-life motion.

Late in this period, motion picture cameras and projectors developed mechanized cranks, which allowed for constant speeds of recording and projection. Even so, individual scenes were oftentimes filmed and projected at varying frame rates due to filmmakers favoring different speeds for different scenes (usually between 18 and 23 fps). Often film reels were delivered with instructions as to how fast or slow each scene should be shown. Additionally, exhibitors and projectionists favored certain frame rates as well, creating further inconsistency. 24 fps was an economical and technical decision.



What changed everything was sound synchronization. Synchronizing sound with film was attempted as early as 1900, but the technology was too unreliable for major motion pictures. By the late 20s, it became possible to sync sound using a phonograph or similar device, interlocked mechanically with a projector. The first "talkie", a film with recorded dialogue, used this method, set at 24 fps. It was 1927s The Jazz Singer.

Eventually, sound was synced to film by actually printing an optical track on the filmstrip alongside the image. This practice linked frame rate to the limitations of audio technology of the time. Given that film is an expensive medium, it was in Hollywood’s best interest to consume as little film as possible during a production. Although silent films ran at an average of 16 fps, it wasn’t possible to produce a quality soundtrack at that frame rate. Eventually, the studios decided on 24 fps because it was the SLOWEST frame rate possible for producing intelligible sound, which means the decision was not an aesthetic decision, but a technical and economical decision.
