4K, UHD, HD recording, 7" 1920x1080 monitoring, advanced playback and editing in a compact, lightweight, affordable add-on to existing DSLR and Mirrorless cameras. More
MSRP: $995

Ninja Assassin extends the Atomos Ninja line up in to the realm of 4K UHD and 1080 60p. Combining professional 4K-UHD/HD recording, 7" 1920x1080 monitoring, advanced playback and editing in a compact, lightweight, affordable add-on to existing DSLR, Mirrorless and HDMI cameras.

The HDMI output is the key to unleashing your camera’s capability, recording pristine footage directly from the camera's sensor to visually lossless Hollywood quality Apple ProRes or Avid DNxHR codecs.

Up to 8 channels of audio over HDMI or analog audio over the additional 3.5mm input allows connectivity from analog mixers or microphones locked frame accurately to your video.

Bypass the highly compressed internal MPEG / h.264 compression from the camera increasing color accuracy (with 4:2:2 color sampling) and color resolution with 10-bit color (1 Billion Colors). The edit ready Apple ProRes or AVID DNxHR video files created by Ninja Assassin are visually lossless with each frame being captured in full resolution (I frame recording) just like film.

Go back in time with Pre-Roll cache recording, up to 8 seconds of HD or 2-3 seconds of 4K-UHD so you’ll never miss that shot.

Video Time-lapse gives enormous creative license with up to 10 different sequences, speed ramp and scheduled start and end times over 24 hrs.

Harness the power of 2.5" computer storage media, making 4K-UHD the same cost as affordable HD today. Record 3 hours of 4K ProRes 422 HQ @ 25 fps on a 1TB SSD, or 10 hours in HD. Atomos have teamed up with the major media brands to ensure availability and reliability you know and trust.

The combination of high capacity media with recording direct from the sensor means that the conventional 30min barrier imposed by many cameras can be bypassed.

The class leading 7" SuperAtom IPS calibrated monitor provides a range of easy to use professional monitoring tools on a high resolution (1920 x 1080) high pixel density (325ppi) screen to ensure perfect shot setup every time. 

Weighing in at only 430g (15oz) the Ninja Assassin is a compact lightweight addition to any DSLR, gimbal or drone application. The rigid ABS polycarbonate structure is further protected by the included Armor Bumper making the Ninja Assassin the ideal go-anywhere monitor-recorder solution.

Instantly review recorded content on screen or out to a larger monitor. 4K recordings can be downscaled to allow connection to HD monitors and you can even create a playlist of favorite clips for simplified client review.
