ntsc-rs is a free, open-source video effect which accurately emulates analog TV and VHS artifacts.

Other popular effects eyeball the look of VHS tapes using simple color lookup tables and overlays. ntsc-rs uses algorithms that model how NTSC transmission and VHS encoding actually work, based on algorithms developed in composite-video-simulator, zhuker/ntsc, and ntscQT.

ntsc-rs is written in Rust, and is multithreaded and SIMD-accelerated. Unlike similar effects such as ntscQT, it can run in real time at much higher resolutions than actual NTSC footage.

ntsc-rs is available not just as a standalone and web application, but also as a plugin for After Effects, Premiere, and all OpenFX-compatible software. This includes DaVinci Resolve, Hitfilm, and Vegas.
