Blackmagic Design Web Presenter 4K

Incorporate live streaming capabilities into your video production configuration with the Web Presenter 4K from Blackmagic Design. This compact desktop unit enables you to connect any SDI video input and stream it live over the Internet, utilizing either an Ethernet connection or tethering via USB to your smartphone with a 5G or 4G network. The SDI and HDMI monitor outputs provide a comprehensive view of live status information alongside your broadcast.

The USB Type-C port facilitates the connection of various USB video sources, including webcams and computers, enabling the transmission of 4K video and audio across any platform and software that supports webcams, such as Skype, YouTube Live, Facebook Live, Twitch, Periscope, Teams, and others, compatible with Mac, Windows, Linux, and Chrome OS systems. It is compatible with the H.264 codec and supports streaming through RTMP and SRT protocols, allowing for resolutions of up to UHD 4K.

The SDI and HDMI monitor ports offer comprehensive status information regarding your feed, enabling you to verify whether you are ON AIR, as well as details about input parameters such as bit depth and stream quality, embedded audio input status, and historical data for both video and audio. Additionally, trend graphs and meters for video and audio are available. Basic status information can also be viewed on the bright LCD screen located on the front of the unit. Furthermore, an SDI loop output is provided for monitoring the original feed and routing it to a switcher or router.

The compact design enables seamless integration into your broadcasting configuration, and it is compatible with optional rack shelves for installation in a 1 RU rack. The dual AC/DC redundant power input is particularly useful in the event of a power outage, and the 4-pin XLR input can be used for DC power. Additionally, the Web Presenter 4K works with the Blackmagic ATEM Streaming Bridge, allowing for the decoding of streams back into HDMI or SDI signals, thereby providing further routing possibilities.

Features

• The Web Presenter allows you to input any 12G/6G/3G/HD-SDI video source up to UHD 4K.
  
  
• 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.
  
  
• 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.
  
  
• 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.
  
  
• 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

• 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.
  
  
• 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.
  
  
• 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 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.
  
  
• 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.
  
  
• 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.
  
  
• 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.
