Atomos Sumo
Atomos packs Sumo with 4K 12-bit RAW, 10bit ProRes/DNxHR, and 1080p60 live switching/recording in a 19” monitor. 

Atomos has unveiled a new 4K recording monitor ahead of NAB. Dubbed Sumo (as E. Honda has already been taken), the 19” HDR 1200nit 10+ stop panel boasts 4K 12-bit RAW or 10-bit 422 Pro 422 ProRes/DNxHR.

Sumo can record HD up to 240p, but what’s intriguing is its ability to live switch and record up to four ISO channels of 1080/60p video that you can mix with cuts and fades using QuadLink SDI connections. Atomos gives you the power to switch between feeds on the screen via cross fade or hard cuts from the locked sources, or you can tag and adjust final edits with metadata tagging, preserving ISO feeds.

Jeremy Young, Atomos’ CEO says, “Seeing innovation come to life is the most exciting part of making technology products. Sumo is one of the most remarkable video products I have worked on. Versatile and highly advanced yet simple to use, it covers all kinds of high-quality production from end to end at a fraction of traditional costs. The Atomos Sumo is truly revolutionary.”

The 19” display is a 1920x1080 10-bit LCD driven by the AtomHDR engine to help map Log/PQ/HLG for 10+ stops of HDR in real time. RAW output over SDI can be paired with a number of cameras: Sony FS5/FS7/FS700, Canon C300MKII/ C500, or the Panasonic Varicam LT. Video is recorded directly to 2.5” SSDs using data rates up to 3.2 Gbps.

For the audiosavvy, full XLR connections provide 48V phantom for microphones or line-level audio. The intuitive menu tree allows adjustments for frame delay and gain. There’s also a 3.5mm stereo headphone jack and a built-in speaker for quick QC.  

Sumo touts both SDI and HMI connections which can convert between HDMI 2.0 & 3G QuadLink/6G/12G SDI in any combination. Quad SDI inputs provide multiple 3G SDI outputs without the need for converters. The HDMI 2.0 supports to 4Kp60 input/output; Atomos has also included Genlock and LTC timecode support as well. 

Sumo is available now with a price tag of $2,495. More info can be found here.

It's a director's monitor AND a grading monitor! This looks like an excellent option for a DP/Colorist, like myself.
