Ninja CAST The combination of the Ninja V and AtomX CAST becomes the Ninja CAST.
Ninja CAST is for video creators or anyone who wants to make broadcast quality multi-camera programs simply and quickly from anywhere. Add professional broadcast quality features to your online meetings, presentations, remote learning/training, virtual conferences, demonstrations or engaging corporate videos.

Best of all, Ninja CAST is simple and easy to use — you don’t need to be a video professional to achieve great looking results.

Broadcast features for everyone
Ninja CAST is a fully functional stand-alone switcher, multiview monitor and broadcast quality recorder that does not require a computer to function.

With a high quality 5” HDR touchscreen monitor, 4 x HDMI inputs and physical buttons, the Ninja CAST is the ultimate portable live switching & streaming solution. Adding Ninja CAST to your production arsenal also gives you the multi-award winning Ninja V – the ultimate 5″ HDR monitor-recorder. As an on-camera monitor, the Ninja V records up to 5.9Kp60 ProRes RAW, provides accurate HDR and LOG>PQ/HLG monitoring and more. 

Simple Switching & Streaming
The flexible control options of Ninja CAST allow you to use either the touchscreen or the physical buttons to ‘switch’ between sources to select the output for your WebCAST or BroadCAST. The illuminated buttons for each input and colored LED lighting for Program and Preview status further simplifies operation and allows you to easily switch & livestream in dimly lit environments.

Connect any full HD video source
Connect mirrorless or DSLR cameras, video cameras, computers, consoles or even pre-recorded content via HDMI. There’s no need to worry about synchronization, as you can mix and match frame rates up to 60p.

Integrates Seamlessly
With the Ninja V docked in, the AtomX CAST connects via USB-C to your computer and appears as a high-quality webcam. Plug and play allows it to work immediately with all your video applications like Zoom, Teams and Skype without the need to install drivers on the computer first. Add up to 4 camera inputs to bring your presentation or meeting to the next level.

Integrated Monitor
Having an integrated monitor allows you to see the incoming signals as a multiview display, without having to connect an additional monitor. With the Ninja V docked into the AtomX CAST, you can utilize its high quality 5” touchscreen for setup and the monitor-assist tools for exposure, focus and image analysis for optimising your shots. In the single input view, Ninja CAST also offers all the same essential monitor assist tools available from your Ninja to allow you to nail exposure and focus on individual inputs.

Enhance your brand, your video and your reach
Sophisticated features like logos, mast head graphics and lower third titles will make your productions look incredible, and the dedicated controls for these functions make them easy to use. Add custom graphics for branding your content, with support for transparency, sponsors’ logos and other on-screen information to your production and configure the layout on the Ninja touchscreen.

One of the benefits of using Ninja CAST with a multi-camera setup is that you can use the Picture-in-Picture function to display two inputs at the same time. Any of the four HDMI inputs can be used for a Picture-in-Picture effect over the program output with controls for size and location of the overlayed image. You can display a close-up of a product on your desk and display your face as a Picture-in-Picture at the same time whilst you talk about the product.

Configurable and adaptable
As AtomX CAST is so compact and versatile, users can easily work alone or with a team to enhance their productions. Solo operators can transport the Ninja CAST in a small backpack and then use it discreetly with compact mirrorless cameras for productions of any size. For larger setups, the Ninja V/V+ HDMI output can be used as a secondary output that can be set up as a duplicate program out, preview monitoring for the crew or talent, or to connect to a larger multiview display.

Ready for advanced workflows
AtomX CAST connected to a Ninja V is a fully functional stand-alone switcher, but you can also use it with a computer for more advanced video work. In this mode, AtomX CAST and Ninja V does the heavy lifting, taking the load off your computer and reducing the likelihood of software crashes with dedicated external video processing.

Simply add AtomX CAST as a media source in OBS, X-Split and VMix to make use of the software application’s additional graphics and scene configuration while using the CAST for video input switching.

Stand out from the crowd
Using Ninja CAST with a camera that has a clean HDMI output and your choice of lens allows you to bring professional production values to any online video stream or meeting. Bring a cinematic look that is dramatically different from the image and impact of your message, putting yourself ahead of the crowd relying average webcam. Utilize the tool in the Ninja V to check your light, camera angles and sound, and you will soon be making professional quality video productions. Many older HD camcorder or photo cameras can output great looking video via its HDMI port, bringing new life to equipment you may already own and let multi-camera enhance your productions.

Broadcast Quality Switching and Recording
Recording and Codec options With professional 10-bit 4:2:2 inputs, you get broadcast quality switching and the ability to record in broadcast quality codecs like Apple ProRes or Avid DNx.

Built in versatility
AtomX CAST can deliver to a worldwide audience by sending a stream to your favourite streaming host, output a broadcast quality video signal to a local display, digital signage or video wall, and record with high quality edit-ready video codecs.
