For our Livestreams, we use some fancy software called Livestream Studio that is installed on the Stream PC (the very very big heavy black box in the office). This post will outline how to set up the Stream PC, set up Livestream Studio and go live!
Setting up the Stream PC
We generally keep any power cables in the bottom drawer of the PC, the camera/sound cables in the middles drawer (ie. SDI, XLR) and the audio mixer, keyboard and mouse in the top drawer.
- Make sure the BLUE power plug is inserted into the (oddly enough) BLUE port at the bottom of the inputs/outputs panel.
- Plug in the:
- Monitor(s)- HDMI
- Keyboard- USB
- Mouse- USB
- Audio Mixer- USB
- Cameras are plugged into the SDI ports (using the SDI cables kept in the middle drawer of the PC) that are numbered 1-8 on the inputs/outputs panel.
- Plug an Ethernet cable into the Ethernet port on the back of the PC and stick the other end into a port in the wall.
Setting up Livestream Studio
- Open up Livestream Studio and hit New Project on the top right of the screen.
- Open up settings (top right of the screen) and hit imputs. Map the video sources that come through the SDI cables (ports 1-8) on the back of the stream PC. This basically means give each camera a name (ie. Fixed Wide, Cam 1, Cam 2) so that you know which camera feed is which.
- Outputs are used for taking a video feed and sending it to somewhere else (eg. to a separate screen in the room or if the vision mixing is happening at a different location).
- Vision Mixing basically means swapping between video feeds. Use the number keys to switch between cameras (the footage for each camera is shown in the middle strip of the Livestream Studio interface). Using the number keys will load a video feed into the preview window- to make it live, hit enter, and the stream will cut to whatever feed is in the preview window.
- Transitions look really cool! They are located in the middle-right set of tabs. The transitions can also be controlled by the slider on the top right of the interface (where the controls for the graphics are). Once selected, hit enter as usual and instead of hard cutting to the preview window, you’ll get a real pretty transition.
- Graphics (GFX) are limited in Livestream Studio to three packages. Generally, one GFX is a beginning/closing screen (ie. Starting soon, thanks for watching), one can be used for people’s names/positions (with transitions) and another for a permanent logo (StagTV). GFX 3 will overlay GFX 2, and likewise GFX 2 will overlay GFX 1. The graphics can be pulled/pushed using the labeled keys on the the keyboard, or by using the graphics window on the top right of the Livestream Studio interface. You can preview the graphics in the graphics window, as well as tying them.
- Pre-recorded video can be played on the stream using the Media tab. The media feed works the same way the camera feed works (ie. it can be cut to, seen in the preview window first, and then made live). Make sure the autoplay (bottom right) is selected so that the media plays from the start each time it is cut to.
- To start the stream, go to the stream tab in the middle of the interface. Hit the ‘+’ sign and select the platform to be streamed to (usually Facebook and/or YouTube).
- Audio Mixing is easier to do using the mixer that can be plugged into the Stream PC rather than using the built-in audio mixer in Livestream Studio. Connect the mixer to the Stream PC, and plug each of the mics into the top of the mixer using XLR cables.
An important thing- Make sure that for the overall stream audio output, both the buttons at the bottom of the output are selected- if only the headphone button is pressed no sound will come out on the stream (this totally hasn’t ever happened before… ever…)
