Atomos Sumo 19 Quad SDI & HDMI 2.0 IN/OUT Monitor-Recorder

The Atomos Sumo 19 is designed to get the most out of video recordings by allowing the user to switch to the best resolution for viewing. It has multiple applications including field use or viewing on a HDR monitor. The Sumo 19 gets its name from the 19” inch LCD display panel with 1920 x 1080 screen resolution. It has the capability to handle output in RAW, PQ, Log or HLG formats and convert them to show more than 10 dynamic range stops in real time.

This is facilitated by the four 1080p channel live switching feature. ProRes RAW is a major feature that maximizes the potential of a RAW camera by preserving pixels at speeds of 5.7 kp30, 2kp240 DCI/HD and 4kp120 DCI/UHD. A 10-bit processor allows 10 bit 4:2:2 recording for either DNxHR codecs or ProRes at a data rate of 1.8 Gbs and 220MB/s.

Video switching is very simple as you can efficiently switch on-screen using effects such as cross fade, cues and hard cuts. The touch screen further simplifies the switching process. Atomos also recognize the value of inputs and outputs which is evident with the dual XLR inputs that are stereo balanced. Frame delay is another feature that is regularly used to synchronize microphone and line-level audio with embedded SDI and HDMI audio sources.

The output, on the other hand, includes quad SDI and HDMI sockets for compatible devices allowing you to convert related formats. The Atomos Sumo 19 stereo microphones are powered with a 48V Phantom power unit which can easily handle field recording.

Atomos have a variety of HDR High Brightness Monitor Recorders including the Atomos Sumo 19, Atomos Shogun Inferno and Atomos Ninja Inferno video recording devices. These devices do more than recording as they are viable HDR production monitors and video switchers as well. You can capture video recorded on any camera and modify the original source video any way you like.

    I have a chance to look at and manner around with this toy at Atomos seminar recently. The first impression was, this monitor/recorder is apparently the blown out of Inferno but with more stuff in it .However my attention was just to focus on it monitor capabilities , though it offers you a 4 x HD stream 1 x 4k Quad link recording and a 4 channel switcher.

    To convince me whether it was a good buy, it is simple, is it worth to buy this 19 inch Monitor with HDR at USD 2495?
    I have look around too whether I could get the similar monitor at the price range less than USD 3000. The answer is Nope. The Sony HD monitor LMD-A170 is currently selling at USD 2599 but it does not have HDR feature. So What I conclusion have I drawn?… It is good value for money to get Sumo as monitor for sure. With optional purchase you can gear it up with sun hood and 2 x battery operated monitor and Atomos is currently designing a rack mount kit for it.

    I am considering to use is at grading and editing monitor, although not the best , at this price point nothing to complaint.
    The sumo is constructed with tough Aluminum alloy chassis with built-in armor houses with 10 mounting points
    metal material around it with weight for just less than 6kg. It is scheduled to have its first Shipment out from factory by End of Jun 2017. The Screen interface work the same way as its Inferno recorder.

    Now I would like to look at the bonus features , 4 stream HD recording ( or 1 x 4K ) and switcher function . it seems that 4 x HD recorder perform like Convergent designed – Apollo , however the switching function and limited switching effect may render it less than a perfect switcher and it records 4 channel instead of 5 ,unlike Apollo ( 5 recording stream including program out) . So like I have suggested, just get it as a 19 inch HDR monitor, the deal is now becoming sweeter by having a 3 years warranty if you registered your purchase online with Atomos.

    Accordingly the first shipment is going to take place by End of Jun 2017.
