How to Use ntsc-rs: Web App, Standalone, or Plugin

Updated

ntsc-rs runs in three forms: a browser web app, a standalone desktop application, and a plugin for video editors. The current download version is 0.9.6. Choose the web app for a quick look, the standalone app for rendering outside an editor, or the plugin if you already cut video in After Effects, Premiere, DaVinci Resolve, or another OpenFX-compatible tool.

The three ways to run ntsc-rs

Form Where it runs Best for
Web app In your browser Trying the effect without installing anything
Standalone application As its own desktop program Processing video when you don't want to open an editor
Plugin Inside a host video editor Applying the effect directly to a timeline

All three use the same underlying effect, so the choice is about workflow, not output.

Web app: fastest way to try it

The site offers a "Try it online" option that loads ntsc-rs in your browser. Use it when you want to see what the effect looks like before committing to a download. It is the right pick for a quick preview or for checking whether the VHS look suits your footage.

Standalone application

Download version 0.9.6 from the site to run ntsc-rs as its own program. This suits you if you want to apply the effect to video files without opening a full editor, or if your editor has no plugin support.

Plugin: for editing workflows

ntsc-rs ships as a plugin for:

  • After Effects
  • Premiere
  • All OpenFX-compatible software, which the site lists as including DaVinci Resolve, Hitfilm, and Vegas

Pick this form if your footage already lives in one of those editors. You apply the effect on the timeline instead of exporting, processing, and re-importing.

What makes ntsc-rs different

The site states that other popular VHS effects approximate the look with color lookup tables and overlays, while ntsc-rs models how NTSC transmission and VHS encoding actually work. It builds on algorithms from composite-video-simulator, zhuker/ntsc, and ntscQT.

It is written in Rust, multithreaded, and SIMD-accelerated. The site claims it can run in real time at resolutions much higher than actual NTSC footage, unlike similar effects such as ntscQT.

Choosing between them

  • Want to test the look right now, no install: use the web app.
  • Want to process files outside an editor: use the standalone app.
  • Already editing in After Effects, Premiere, DaVinci Resolve, Hitfilm, or Vegas: use the plugin.

The site describes ntsc-rs as free and open-source. It does not state pricing, account, or login requirements for any of the three forms, so check the download and web app pages directly if those details matter to you.
