Atomos Ninja Phone Overview
The Ninja Phone Video Co-Processor from Atomos is a 10-bit video co-processor for smartphones and tablets that lets you record from professional cameras via HDMI, with support for UHD 4K, DCI 4K, 1080p, and 720p video at frame rates up to 60 fps. Designed to take advantage of the iPhone 15 Pro/Pro Max, 16 Pro/Pro Max, and their OLED display, the Ninja Phone lets you encode an HDMI signal to ProRes or H.265. Encoded video is sent via a USB-C output to your iPhone's USB-C input, where its A17 SoC processor decodes the signal and displays it on your iPhone's screen, which features a 2,000,000:1 contrast ratio and supports Dolby Vision, HDR10, and HLG. It can also display 11 stops of dynamic range and a peak brightness of 2000 nits. ProRes encoded video may be stored on your iPhone as a .mov file and/or simultaneously transcoded to 10-bit H.265 for workflows that include camera-to-cloud or live streaming using the iPhone's 5G and Wi-Fi 6E connectivity.
You'll also be able to take advantage of external iPhone accessories using a separate USB-C port that allows you to work with microphones and other third-party accessories. Power is delivered using NP series batteries, a battery eliminator, or a USB-C 5V/3A input. When one of these power sources is in use, the Ninja Phone also charges your phone and any connected accessories, helping to ensure longer operating times.
The Ninja Phone iPhone app, which is available as a free download, makes it easy to control and coordinate both the Ninja Phone and your iPhone. It also lets social media creators shoot in 16:9 horizontal or 9:16 portrait mode and is available for iOS and iPadOS.
The Ultimate Smartphone Accessory
Today's smartphones are technological marvels, with amazing displays, cutting-edge Wi-Fi 6E and 5G connectivity. But how do you connect your pro camera? With Ninja Phone. Attach it to a compatible smartphone, plug in an HDMI-equipped camera, install the app, and you're Ninja'd up and ready to go.
How Does It Work?
Ninja Phone takes any HDMI video signal and instantaneously converts it into a high-quality video file format. This video data is then transferred in real-time to USB-C-equipped smartphones and tablets, turning them into professional low-latency video monitors, recorders, and live streamers.
 
It's ideal for professional filmmakers, social media content creators, and a wide range of applications like gaming, where you need to record or stream a video source without a computer. It also sets you up for hyper-efficient camera-to-cloud workflows.
Make Your Phone Display a Pro Video Monitor
Turn your smartphone into a top-notch HDR monitor. Connect your camera, and you have access to some of the world's best portable displays. Atomos' Ninja Phone app adds a host of professional monitoring tools and even adapts to vertical orientation. Today's smartphone displays are incredible OLED devices with extraordinary 2,000,000:1 contrast ratios and 460 ppi resolution, and, with Ninja Phone, the ability to display the output from any HDMI-equipped camera.
Capture 10-Bit Video from an HDMI Camera
Ninja Phone is the only way to connect professional cameras with HDMI to a compatible smartphone and record directly into 10-bit Apple ProRes (iPhone only), the absolute standard for professional video production and post-production, or 10-bit H.265.

Send via 5G or Wi-Fi 6E to Social Platforms
You won't find a more compact set-up for streaming professional-grade video directly from your camera. Ninja Phone and an iPhone Pro Max weigh only 11.8 ounces, and the combination is packed with the latest technology, including pristine 10-bit, H.265 encoding, Wi-Fi 6E, and low-latency 5G for the ultimate in mobile live streaming.
Stunning 10-Bit HDR Pipeline with a Billion More Colors and Shadows
Atomos uses its unparalleled experience in video encoding to pass 10-bit 1080p or 4K HDR video from your camera's image sensor over HDMI to Ninja Phone, then through USB-C to your smartphone or tablet's processor. The result is stunning, professional-quality images on your device's incredible screen, with virtually no latency.
 
The 10-bit video preserves massively more picture information, both in terms of color and brightness, than 8-bit formats. The number of colors goes from millions to billions, and the detail within the brightness range— the highlights and shadows in the image—is more than four times that of 8-bit.
 
Today's camera sensors all capture more than 10-bit, and all modern TVs, smartphones, and tablets have advanced 10-bit HDR screens too. With Ninja Phone, you can deliver the best possible video quality on every shoot.
8-Bit vs. 10-Bit
With Apple ProRes encoding, Ninja Phone sends 10-bit color and brightness information from your camera to your smartphone's screen. Professionals demand 10-bit because it shows accurate colors, highlights, and shadows and removes contours between similar colors. So, a blue sky looks real, or a candle looks vivid in the dark, with no washed-out painting-by-numbers pictures. With 8-bit, you're throwing away the subtlety and nuance, often leaving visible steps and flat imagery that can't be repaired in editing. 
 
In the same way, 10-bit video encoding and compression preserve color, shadows, and highlights to give depth and nuance to the image, just like our eyes can see. This is High Dynamic Range, or High Brightness Range. 10-bit gives a billion levels of shadows and highlights in an image to recreate all the depth and reality of real life, all on your smartphone and direct from your professional camera and lens.
