Atomos Shogun & Ninja Assassin 6.6 Update: AtomHDR, Slow Motion Playback & More

Atomos has released a major update for their Shogun and Ninja Assassin Recorders, adding their AtomHDR feature to both devices.


  • AtomHDR is now available on Shogun
  • HDR monitoring is supported on log cameras from Sony, Canon, Arri, Panasonic, JVC and RED.
  • Improvements have been made to colour gamut accuracy.
  • Improvements to accuracy and resolution in blacks when using AtomHDR mode.
  • A visual improvement has been made to the AtomHDR slider for easier access.
  • While in AtomHDR mode, a simplified HDR waveform line has been added to easily set the correct slider position for the dynamic range of the scene.
  • AtomHDR includes options for WFM Auto which automatically sets the HDR level for the current scene’s max brightness and WFM HDR which scales the WFM to view the HDR range to the full height of the WFM.
  • The waveform monitor will now display a percentage scale based on the input log mode.
  • Slow motion is now available in playback mode. Pausing video playback will automatically display the slider above playback controls and give you access to forward and reverse speed adjustments.


Bug Fixes:

  • Fixed an issue where some files exported from NLE’s did not play audio.
  • Fixed an issue where waveform monitor graticules were not visible with some menus on the screen.
  • Fixed an issue where monitor would sometimes appear jerky when panning at 1080p60.
