 Unleash your cameras HDMI

The HDMI output is the key to unleashing your camera’s capability, maximizing video image quality by recording your footage directly from the camera’s sensor. We then record this pristine image to Hollywood quality Apple ProRes or Avid DNx codecs. The edit-ready video files created by Ninja Assassin are visually lossless with each frame being captured in full resolution, just like film!

 Assassinate MPEG Poor Quality

Bypass the highly compressed internal MPEG / h.264 camera compression increasing color resolution (with 4:2:2 color sampling) and color accuracy with 10-bit color (1 Billions Colors) in all recordings.

 4K Recording at HD Prices

Harness the power of 2.5" computer storage media, reducing cost and increasing capacity and reliability, making 4K the same cost as affordable HD today. 4K recording onto 1TB delivers an amazing 3 hours of ProRes 422 HQ @ 25 fps, and HD recording onto affordable HDD's, such as a 1TB delivers 10 hours of ProRes 422 HQ @ 25 fps. Atomos has teamed up with the major HDD and SSD companies in the world to ensure availability and reliability you know and trust.

 Professional shot setup you can trust

Ninja Assassin provides a range of easy-to-use professional monitoring tools which include Focus Peaking, 1:1 & 2:1 Zoom with silky smooth image pan & scan, False Color (skin tones), and Zebra and Waveform/Vector Scopes for in-depth image analysis. Out of the box the display is color calibrated to REC709 standard, is capable of delivering 100% of sRGB, with 1080p resolution and over 320 pixels per square inch. Shot set-up with waveform and vectorscope means accurate color and white balance every time.

Ninja Assassin puts a wealth of smart production tools in your arsenal that's designed to allow you to:

  • Go back in time with Pre-Roll - up to 8 seconds for HD or 2-3 seconds of 4K, 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.
  • Anamorphic de-squeeze - the perfect companion for Panasonic’s Anamorphic and affordable anamorphic lenses.
