Atomos AtomX Cast HDMI

Multi-input switching. Made simple.
The AtomX CAST is a modular, multi-input HDMI switcher designed to turn your Ninja, Ninja Ultra, Ninja V or Ninja V+ into a compact, full-featured live production studio. Whether you’re streaming, presenting, or switching live to screen, CAST makes professional multi-cam workflows easy, affordable, and portable.

Four HDMI Inputs with Seamless Switching
With four HDMI inputs, AtomX CAST lets you connect up to four cameras, computers, gaming consoles, or other video sources. You can switch between them in real time using the integrated hardware buttons or via touchscreen when paired with a Ninja V or V+.

Broadcast-Quality Output
CAST delivers clean 1080p60 video with professional-grade switching transitions and graphics overlays. It outputs via HDMI or USB-C, allowing you to use it as a webcam source in conferencing platforms like Zoom or Teams, or as a live feed into streaming software like OBS and vMix.

Plug-and-Play USB Streaming
The USB-C connection functions as a UVC (USB Video Class) output, meaning it is instantly recognized as a webcam source on your computer without any drivers or configuration. Just plug it in and go live with broadcast-level quality from your multi-camera setup.

Modular Design for Ninja, Ninja Ultra, Ninja V/V+
The AtomX CAST docks directly to the Ninja V or V+ via the AtomX expansion port, creating an all-in-one device for monitoring, switching, recording, and streaming. When not in use for switching, the Ninja V/V+ operates as a standalone HDR monitor-recorder.

Multiview and Overlay Tools
Easily display multiview layouts and apply graphics overlays like logos, lower thirds, and titles—all customizable through AtomOS. Preview all inputs at once and switch seamlessly with complete confidence in your live program feed.
