ntsc-rs is a free, open-source VHS and analog TV video effect. Use it online in your browser, as a standalone application, or as a plugin for DaVinci Resolve, After Effects, and more.
NTSC-RS is a free, open-source video effect that accurately emulates analog TV and VHS artifacts. Unlike simple overlays or color lookup tables, it uses algorithms that model how NTSC transmission and VHS encoding actually work. You can use it online in your browser, as a standalone application, or as a plugin for popular video editing software.
NTSC-RS models the actual physics of NTSC transmission and VHS encoding, based on algorithms from composite-video-simulator, zhuker/ntsc, and ntscQT. This produces artifacts that look and behave like real analog video, not just a color overlay.
Written in Rust and accelerated with multithreading and SIMD instructions, NTSC-RS can run in real time at much higher resolutions than actual NTSC footage. This makes it practical for live use and high-resolution projects.
Use NTSC-RS online directly in your browser, download it as a standalone application, or integrate it as a plugin for After Effects, Premiere, and all OpenFX-compatible software — including DaVinci Resolve, Hitfilm, and Vegas.
"ntsc-rs uses algorithms that model how NTSC transmission and VHS encoding actually work."
Most VHS effects simply overlay a color lookup table or a few scanlines. NTSC-RS goes deeper, simulating the actual signal processing that created those nostalgic artifacts. The result is a far more authentic retro look that responds naturally to different source material.
You want a free, open-source VHS effect that prioritizes accuracy over shortcuts. Whether you're editing in DaVinci Resolve, After Effects, or just experimenting in your browser, NTSC-RS delivers genuine analog artifacts with real-time performance.
