With its large, bright color-accurate 19" LCD screen and 4K recording capabilities, the Atomos Sumo can be implemented to enhance professional video workflows

in both production and post-production.

Realtime Exposure on set from Log for HDR & SDR
The AtomHDR engine perfectly maps Log/PQ/HLG from popular cameras/ game consoles to SUMO19M's amazing panel, resolving 10+ stops of HDR in real-time for perfect setting. Pass-on HDR to other devices over HDMI or SDI, in HD or 4K and in Rec709/HLG/PQ. To get the best image from your sensor, you must shoot Log and only AtomHDR makes exposing Log easier, unlocking every camera's HDR potential. The SUMO19M inputs can be used as an editing and grading companion in the studio with full SDR & HDR support through 709/HLG/PQ.

Monitoring made even Simpler with AtomOS 8
The SUMO19M is all about performance monitoring; HDR or SDR, 4Kp60 or HD, 12G-SDI or HDMI 2.0 and everything in between. With the recording functions removed, the user interface has been redesigned to emulate a button-based monitor. All the precision scopes can be accessed from the bottom of the screen as an overlay - simple and intuitive adjustments, just like your phone.

Noise Free SDR with Log & AtomHDR
Today's productions require flexibility to perform, no matter the camera or production you MUST be able to deliver superb SDR or mind blowing HDR to your clients. Shooting Log from your camera and exposing using AtomHDR gives you the maximum latitude and flexibility in Post Production to produce the cleanest noise-free SDR image and highest dynamic range HDR.

Selectable Dual 12/6/3G-SDI input for A/B comparison
The SUMO19M accepts up to 4Kp60 or HDp240 over HDMI or the dual 12/6/3G-SDI inputs. Additionally, there are dedicated input selection buttons on the user interface to make A/B comparison between sources simple and simultaneous HDMI and SDI output of the corresponding input for routing to other monitors, recorders or switchers.

3D LUT's - Precise, Flexible and Infinite.
Load an infinite number of custom LUT's onto SUMO19M via the HDD/SSD slot. Apply and compare looks for finishing in SDR or HDR, form your favourite LUT for your camera or from your post team for consistency across shoots. All stakeholders from customers to directors can see the creative finish live on the day!

High Bright 1200nit 19" calibrated 1920x1080 monitor
The extremely bright 1200nit display means you can accurately monitor, even when outside in full daylight. SUMO19M has a wide viewing angle so that everyone on set can review the action and also features optional calibration using X-Rite's i1DisplayPro for ongoing accurate HDR and Rec709 monitoring.

Built for production
The Aluminium alloy chassis with built-in armor houses sixteen 1/4" and eight 3/8" mounting points around the top/bottom/sides, a rear panel VESA mount and included feet for a variety of mounting configurations.

Continuous Power
The optional mounting plates connect dual V-Lock or Anton Bauer batteries that work in tandem with our patent pending continuous power system. Sumo automatically swaps to the second battery when power is low, allowing the drained battery to be hot swapped to ensure you are never without power in the field.
