Atomos today released a new version of their AtomOS for the Samurai Blade external HD-SDI recorder. Version 5.1 focusses on screen color adjustments with controls for Gamma, Y Lift and Y Gain. Canon Cinema EOS users will benefit from a new on screen C-Log color display. A single button push allows the user to toggle between Rec. 709 and C-Log color. Atomos Spyder color calibration support has also been added to AtomOS 5.1. The Blade is the world’s first portable recorder to feature on-set screen color calibration. Featuring calibration Matrix and 1D LUTs. Also added is D-tap mode which gives a visual indication of when the recorder is running on AC power. This stops constant checking between batteries which has reportedly caused mic clicks due to earth loops in some camera situations. Hit the link to download the firmware.
