## What it is
ntsc-rs is a free, open-source video effect that accurately emulates NTSC analog TV and VHS artifacts using algorithms that model how composite video transmission and VHS encoding actually work. It is available as a standalone application, a web app, and as plugins for After Effects, Premiere, and OpenFX-compatible software such as DaVinci Resolve.

## Use cases
- add a realistic VHS look to videos
- simulate NTSC analog TV artifacts in footage
- apply retro analog video effects in After Effects or Premiere
- give modern video a 1980s/90s tape aesthetic
- process video with an accurate composite video simulator
- try a VHS effect online in a browser

## When to choose
- you need physically accurate NTSC/VHS emulation rather than color lookup table approximations
- you want the effect integrated into your video editing workflow via OpenFX, After Effects, or Premiere plugins
- you need real-time performance at high resolutions
- you want a free, open-source alternative to ntscQT

## When to avoid
- you need effects for other analog formats beyond NTSC/VHS-style artifacts
- you require a lightweight color-overlay VHS filter with minimal setup
- you are on Linux and cannot install the required GStreamer packages

## Facets
- artifact type: application
