Blackmagic Design Web Presenter 4K Overview

Add live streaming to the internet to your video production setup using the Web Presenter 4K from Blackmagic Design. The Web Presenter 4K is a compact desktop device that allows you to connect any SDI video input and stream it live onto the Internet, using Ethernet or tethering via USB to your smartphone using a 5G or 4G connection. The SDI and HDMI monitor outputs allow you to see a wide range of live status information along with your broadcast.
The USB Type-C port allows you to connect any USB video source such as a webcam or computer, so it's capable of broadcasting 4K video and audio on any webcam-compatible platform and software such as Skype, YouTube Live, Facebook Live, Twitch, Periscope, Teams, and more on Mac, Windows, Linux, and Chrome OS systems. It supports the H.264 codec and streams via RTMP and can stream in resolutions up to UHD 4K.
The SDI and HDMI monitor ports provide detailed status information on your feed, so you can monitor whether you are ON AIR as well as input status such as bit depth and stream quality, embedded audio input status, video and audio history, trend graphs, and video and audio meters. You can also see basic status information on the bright LCD screen on the front of the unit. There is also an SDI loop output for monitoring the original feed and sending it to a switcher or router.
The compact form factor allows you to fit it right into your broadcast setup, and it is compatible with optional rack shelves, in case you want to install it in a 1 RU rack. Its dual AC/DC redundant power input is handy, in case you lose mains power, and you can utilize the 4-pin XLR input for DC power. The Web Presenter 4K is also compatible with the Blackmagic ATEM Streaming Bridge to decode the streams back into HDMI or SDI signals for additional routing options.
Input any SDI Signal
The Web Presenter allows you to input any 12G/6G/3G/HD-SDI video source up to UHD 4K.
4K Output
The program and USB Type-C outputs supports UHD 4K video. The unit will downconvert 4K video if you are streaming in HD. When streaming 4K, it will pass 4K video as well as upscale HD to 4K video.
Live Streaming Options
You can stream H.264 video via RTMP streaming protocols to the internet via Ethernet or tether a 5G or 4G phone to use mobile data.
USB Source as Webcam
The built-in USB Type-C input works like a webcam, so you can connect a computer and use any streaming software, or even Skype or Zoom. Stream in 4K over the USB Type-C connector, if your software supports 4K.
Monitor Outputs
SDI and HDMI monitor outputs allow you to see the input video as well as display accurate audio levels, on air status, data rate, and cache levels.
Built-In Technical Monitoring
Feature-Rich Program Status
The graphics-based monitoring output includes a video view, audio meters with accurate ballistics, trend graphs for codec data rates, and cache fill, plus a summary of the streaming settings and detailed SDI technical information.
Streaming Status
There's a very-large ON AIR indicator on the top left of the monitor output, so it's always clear when you are online and streaming. Plus all your current streaming settings are displayed clearly.
Video Input Status
The SDI input technical details are displayed, such as video standard and ancillary data. The bit activity indicators let you see the quality and bit depth of video before H.264 encoding.
Audio Input Status
Audio is de-embedded from the SDI input and the channel status is displayed. The bit activity indicator lets you check for 16-, 20-, or 24-bit audio. You can even see which audio channels are present.
Video and Audio History
The audio and video technical displays also include a 6-second history display, so you can see the recent video input history. This ensures you can instantly see what's been happening.
Trend Graphs
The trend graphs below the video display let you see the last 60 seconds of codec data rate and cache fill. Plus, codec data rate is critical for ensuring you have enough internet speed from your ISP.
Video and Audio Meters
A large area is dedicated to the video input display, and the large multi-segment audio meter with accurate ballistics. You can even change the type of audio meter from VU, PPM, and more.

Blackmagic Design Web Presenter 4K Reviews

Works Like a Charm

By Brandon

Works like a charm straight out of the box. Made our switch over from Teradek painless and relatively inexpensive. Have been running these units for about 6 months now with no complaints.

Missing?

It doesn't even come with a power cord. Provide your own ins/outs, ethernet, connections, sure, but power? What am I supposed to do without power? There's a jack for a 12v DC and a port for a standard three-prong power cord, but neither is included. I would have liked to know this before purchasing. Now I have to order more stuff? Super lame.

Good performance, needs further development

I'm still in the initial phase of testing and usage, but have generally enjoyed the quality it yields. I wish it had a better app layout for the control software, as this feels fairly basic (almost primitive). The .xml files used to create presets are awkward. It was strange to have to look around the internet to find a template version to tweak for my setting. Though I won't be primarily using this to stream to YouTube, I was a bit unnerved by others' claim of 4k streaming problems on that platform, but have yet to experience any troubles during testing. Overall, I think this is a great unit, but would love to see some robust firmware updates.

Up and running within minutes. We were having trouble streaming with some conflict between OBS and ProPresenter 7 having our livestream freeze up constantly even though we have an extremely powerful system. After we got the Blackmagic Design Web Presenter 4K we have had no issues with freezing and the color of the livestream is more accurate as to the color of the cameras we are using. Wish we had gotten it sooner.

One Worked, The Other Didn't

I bought 2 Blackmagic Design Web Presenter 4Ks, and out of the box one of them would not even power on. The reason this is 4 stars instead of less, BH made it painless to get it replaced with a new one that works perfectly and is in use. Moral of the story, test this thing right away, there are quite a few (50% in my case) that have bad power supplies.
