Overlays & Background
An overlay is simply one playlist asset playing atop another at the same time. Legion allows you to pre-assign up to two other assets that can be used over a base asset. These overlaying assets must already be included into the playlist as an entry of their own.
Since an overlay sits over the base asset, generally you would not want the overlay to completely obscure the base layer, that why assets like lower-third graphics are designed with parts being transparent or if the overlay is just a bug it would at need to be reduced in size.
Having the overlay asset included into the playlist on its own allows it to take full advantage of all the features afforded to any other asset. This makes it easy to perform any needed adjustment to properties such as shaders effects, geometry settings, transition effects, time trims, looping, etc.
Once the overlay asset is ready, use following controls on the base asset to setup the assignments.
TIP: Refer to either of thess topics Thumb Panel Detail or Data Grid Detail to see controls that allow you to manually play and overlay.
In the opposite direction we have an additional layer that can be leveraged and that is the background area behind the primary asset. If the primary as well as all overlay assets are reduced to a size smaller than the overall pixel space size then the remaining space will simply be black. However, if you had included program background files, you could select one of those to always appear when this primary asset is taken to program and automatically fade out when the primary asset has ended.
Since the setup is exactly the same for both overlay slots, we decided to just annotate one of them.
Background Selector
Choose from the list of already added program background assets to appear every time this primary asset is taken to program.For convenience, you can use the file browse button to add any additional files. Files added here will be included as part of the list of overall available backgrounds.
Set the duration amount in seconds to a value greater than zero will force the overlay to automatically transition out once the amount of time has elapsed. Time begins as soon as the overlay is instructed to play. Elapsed time will always begin at zero any time the overlay is played. Setting the value back to zero will cause the overlay to remain visible until you manually tell it to stop.
When the auto launch is checked, anytime the base asset begins playing in program the overlay will begin as well. You can however, delay that start by typing a value, in seconds, greater than zero into the delay text field.
