Livestream Studio HD31

The Livestream Studio HD31 Live Production Switcher is an all-in-one, 3-input computer-based switcher running Livestream Studio software. Three Blackmagic DeckLink Mini Recorder cards allow you to capture SD or HD video from HDMI or HD-SDI sources - each card features both connectors, however only one can be used at a time. The Studio software lets you switch between these plus two "remote" channels as well as prerecorded clips in the media player. You can also add titles and effects either as overlays or using the DSK (downstream keyer), apply transitions, and more. An internal encoder gets the program feed ready for the Web, outputting a fixed bitrate 480p H.264 stream via the HD31's Ethernet port. At the same time, the software can record a high-quality - up to 1080p - feed for archiving or editing, encoding it in the MJPEG codec at up to 100 Mbps.

Powering the HD31 is a specially-built computer with a 4.0 GHz quad-core i7 processor, 16GB of RAM, and a 2TB 7200rpm hard drive capable of storing up to 40 hours of 1080p, 100 Mbps footage. For monitoring and operating the software there are VGA, DVI-D (digital only), and HDMI outputs. These allow you to connect a regular computer monitor or TV, and up to two displays can be used concurrently. The Livestream Studio software features a configurable layout that allows you to view all of the camera/input feeds, program and preview, clips in the media player, audio levels, and more - all on one screen if necessary.

Audio is also supported, and can be mixed in software. Up to 24 mono channels or 3 stereo pairs embedded audio through the Mini Recorder cards as well as separate audio via the 3.5mm line-in on the computer's sound card. If you prefer to use an external analog to digital converter or USB audio mixer, there are four DAC-UP USB 2.0 ports which are specially engineered to minimize noise when connecting an audio interface.

The HD31 can be rack-mounted using the included accessories, making it suitable for studios, production facilities, live venues, and production trucks. Also included is a twelve month telephone support plan, a configurable, color-coded Livestream production keyboard, a mouse with mousepad, and power cord.

Create templates to quickly change sport scores, lower third text, or other graphic elements on-the-fly
Downstream Key Overlays
Overlays graphics as layers on top of your program mix with transparency. This is ideal for adding corner bugs, sport cording, lower thirds, picture-in-picture, and other broadcast graphics
Composite up to two live audio/video sources together within the graphics editor. Ideal for a simple second camera angle, a scoreboard cam, or a broadcast network two-person live chat over an animated background video
Media Recording

You can also open the files being recorded in the media player to trim and replay segments from your live show without stopping the recording

Build playlists, loop clips, and auto-play on transition. Trim clips down for broadcast, and quickly scrub to find exactly what you're looking for. If a clip does not match your project settings, the built-in transcoder will convert the file to match. Additionally, thanks to the ISO recording feature, you can get basic instant replay functionality by loading one of your ISOs into the media player
