The Atomos Sumo has a 19” 1920×1080 10-bit LCD panel with 1200nit brightness. It is based on the same architecture as the Atomos Inferno, with 4K60fps, Quadlink and HDMI 2.0, but more is built under the hood. The AtomHDR engine “maps the Log/PQ/HLG from popular cameras, game consoles or TV makers to perfectly resolve 10+ stops of HDR in real time”. The calibration on the Sumo lets you use the i1DisplayPro from X-Rite to always ensure accurate HDR and Rec709 monitoring.
The Sumo can capture 12-bit 4K30p as CDNG or 10-bit Apple ProRes / Avid DNxHR up to 4K60p / 2K240p Raw using the SDI outputs from the Sony FS5/FS7/FS700, Canon C300MKII/C500 or Panasonic Varicam LT onto widely available 2.5″ SSD’s.
The Atomos Sumo incorporates live-switching. You will be able to switch and mix a live record up to four HD ISO recordings using the QuadLink SDI connections, as well as switch between feeds on screen with cueing, cross fade and hard cuts from the locked sources, or tag and adjust final edits with advanced metadata tagging preserving ISO feeds.
The 3G QuadLink/6G/12G SDI connections on the Atomos Sumo allow you to connect cameras with multiple 1.5 or 3G SDI outputs without the need for converters, while its HDMI 2.0 connectors support up to 4K60p input/output along with the open protocol that supports HDR automation, including importing of camera settings. There is also support for Genlock and LTC timecode.
Sumo has full-size XLR connections to connect external microphones, and includes 48V phantom power to supply to them. Dedicated meters and adjustments for frame delay and gain, as well as a 3.5mm stereo headphone jack and built-in speakers, complete the package for a true all-in-one recorder.
