# Supported input class
<a name="inputs-single-standard-vpc"></a>

In MediaLive there are two kinds of class for inputs — standard class inputs and single-class inputs. Some inputs can be set up as either input class. Some inputs can be set up only as single-class inputs. 

When you have a choice, the type to use depends on whether you want to create a standard channel, in order to implement pipeline resiliency. For more information, see [Choosing the channel class and input class](class-channel-input.md).
