Blackmagic launches Web Presenter 4K

Blackmagic launches Web Presenter 4K

Blackmagic has launched Web Presenter 4K, a compact desktop device which helps in webstreaming by taking in any SDI video input. It can use ethernet or work by tethering with your 4G/5G smartphone. This is a very important piece of hardware for those who are into livestreaming.

The ability to connect your smartphone means one can livestream from the field. The phone connection can also act as a backup for the ethernet connection. Both Apple as well as android phones work with the web presenter 4K.

The USB connections for tethering phones are in the front as well on the back panel. It can also autodetect when a phone is connected and switch the internet connection to mobile data. One can also select Ethernet priority or phone priority so that it works automatically as a backup internet connection.

Its SDI and HDMI monitor allows to see various status information while broadcasting.

It has a USB-C port where you can connect your USB video source or even your laptop. It can broadcast 4K video and audio live to popular platforms like youtube, Skype, facebook, Twitch, Teams, Periscope etc. It is compatiple on Mac, Windows, Linus and Chrome OS.

Blackmagic Web Presenter includes a 12G‑SDI input with support for all HD and Ultra HD formats up to 2160p60. A 12G‑SDI loop output is included enabling you to loop video through more than one web presenter, so you can stream to multiple services. Blackmagic Web Presenter features Teranex conversion technology on the SDI input for incredibly clean looking video. Blackmagic Web Presenter takes the incoming HD or Ultra HD input signal and automatically converts it to high quality, low data rate 1080p HD or high resolution 2160p60 Ultra HD depending on the model, which is then sent to the hardware H.264 encoder for streaming. All this means you can use any HD or Ultra HD source for streaming!

The Blackmagic Design Web Presenter 4K supports H.264 codec and uses RTMP for streaming. It can stream upto UHD 4K (3840 x2160) (and not DCI 4K). If you are streaming in UHD 4K and your source is HD, then it will auto covert the HD stream to UHD 4K. Similarly it can also downcovert a UHD 4K video to HD and stream it if you are streaming at HD.


Client can watch live shoot:

Blackmagic Web Presenter features two USB connections that operate as a simple webcam source. That means you can plug into any computer and work with any video software. The software is tricked into thinking the web presenter is a common webcam, but it’s really a broadcast quality SDI video source! That guarantees compatibility with any video software in full resolution 1080 HD or even 2160p Ultra HD quality, depending on the model! As a result, one can connect web presenter to a camera and then Skype/ Zoom call client with live video of a shoot! This feature will really come in handy for some of our corporate shoots where client is abroad and wants to check while the shoot is going on.

When you need to live stream multiple cameras and laptop presentations, one can simply add a live production switcher such as an ATEM Television Studio HD.

Web Presenter works with any video software including Zoom, Microsoft Teams, Skype, Open Broadcaster, XSplit Broadcaster and more


Built-in Technical Monitoring

Traditional broadcast transmitters are critical equipment in a television station, however now the streaming server is just as critical because millions of viewers can be watching globally! To help, Blackmagic Web Presenter includes a feature rich technical monitoring output. 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. Plus the technical monitoring output works in full 1080 HD and outputs to both SDI and HDMI. That means you can use an SDI router for monitoring multiple units, or connect a simple HDMI TV!

1. 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.

2. 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.

3. 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!

4. 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.

5. 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!

6. 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!

It works both on AC as well as DC power.


Broadcast Links with ATEM Streaming Bridge!

While Blackmagic Web Presenter can send video to a wide range of streaming services, it can also be used as a private broadcast SDI video link between studios! The ATEM Streaming Bridge is a video converter that lets you receive the H.264 stream from Blackmagic Web Presenter and then convert it back to SDI video. This means you can send video between remote locations across your local Ethernet network, or via the internet globally! That’s all possible due to the built in H.264 hardware codec that decodes the Web Presenter stream. So one can set up multiple television studios and use ATEM Streaming Bridge and Web Presenter for video links between sites.

Price: $695 US Dollars
