SDI and HDMI monitor outputs allow you to view a wide range of live status information along with your stream.

It supports H.264 codec and streams over RTMP and can stream in resolutions up to UHD 4K.
SDI and HDMI monitor ports provide detailed status information on your power, so you can monitor whether you are IN THE AIR, as well as input status such as bit depth and transmission quality, built-in audio input status, video and audio history, trend charts and video and audio meters. You can also see basic status information on the bright LCD display on the front of the unit. There is also an SDI loop output to monitor the original power and send it to a switch or router.
The compact form factor allows you to fit it directly into your transmission configuration and is compatible with optional rack racks in case you want to install it in a 1 RU rack. Its dual AC/DC redundant power input is useful in case you lose mains power and you can use the 4-pin XLR input for DC power. The Web Presenter 4K also supports Blackmagic ATEM Streaming Bridge to decode streams into HDMI or SDI signals for additional routing options.

Trend charts
Trend charts under the video screen allow you to see the last 60 seconds of codec data rate and cache filling. In addition, the data rate of the codec is critical to ensure that your ISP provides you with sufficient internet speed.
Video and audio meters
A large area is dedicated to the video input screen and the large multi-segment audio meter with precise ballistics. You can even change the audio meter type of VU, PPM and more.
