This document contains references for the settings of several basic Media assets. For capture cards, refer instead to the Professional Video I/O documentation.
Player Overrides
Many of the Media Source assets provide Player Override settings, which you can use to control which player to use to play the asset. Each platform has its own options which you can set separately using a dropdown menu. In all cases, the Automatic option means playback uses the UE default player. Refer to the Electra Protron Player documentation for more information on setting the default player.
Capture card players (AJA and Blackmagic) are only available when the associated capture card hardware is installed and the plugin is enabled. Similarly, NDI is only available when the associated plugin is enabled.
