Below the playlist you will find the buttons for controlling the overlays and the actions. Overlays can be graphics (with or without transparency), text overlays or text crawlers, which you can place manually or automatically over the output video signal during playback from the playlist. Actions are individual media files in direct access. Pressing an action button interrupts the current playback and starts the stored media file. You can set how PLAYDECK should behave after the action file has finished playing. Please refer to chapter 4.2 Working with Actions for more details.
