| # Video Mixer Basics | ||
| # What is a video mixer? | ||
|
|
||
| Unfinished placeholder page. | ||
| A video mixer is the core of any modern video studio. It's a system (usually a dedicated "magic box" type device, but sometimes a computer program) for smoothly switching between multiple video sources and combining then with effects like green screening, overlaying, etc. | ||
|
|
||
| A couple important words: | ||
|
|
||
| - **Sources**: These are the things that feed video into the mixer. Most of the time this will be a camera or a computer. | ||
| - **Buses**: Places to put video | ||
| - **Program Bus**: This is what's on air; your audience will see whatever's on the program bus. | ||
| - **Preview Bus**: This is a place to queue things up for the program bus. To smoothly move something to the program bus, you'll put it on the preview bus first. | ||
|

||
| # Connecting Sources | ||
|
|
||
| Modern video mixers almost always accept HDMI, SDI, or both. | ||
|
|
||
| ### HDMI | ||
|  | ||
|
|
||
| You've probably used HDMI before. Computers, TVs, game consoles, and countless other things use it. It's a very consumer-oriented standard, but it's also common in the broadcast world. | ||
|
|
||
| ### SDI | ||
|  | ||
|
|
||
| You may have never seen this before. SDI is a broadcast/professional standard; you don't see it too much in the real world. It uses BNC connectors, and it's capable of 4K and higher video. | ||
|
|
||
| ### Example Mixer Connections: | ||
|  | ||
|
|
||
| As you can see, our mixer has connections for both HDMI and SDI devices, but it gives its final output in SDI. | ||

||
| # Operation | ||
|
|
||
| See this video tutorial. The tutorial is shot on an older version of the ATEM video mixer, but the operation is still the same. | ||
