# Test streams

Test Stream generator — a test signal (test card). Lets you build generated video streams as fillers for the air or fall-backs during failures of the main streams. The picture type, audio and overlaid text and time can all be configured.

It is configured by enabling the corresponding type of `input` for the stream. It is possible to set video format type, resolution, bitrate, sound volume and frequency, etc.

A list of available Test Streams is available in the left side menu of the program.
