Alpha Merger

Compatibility

Alpha Merger is compatible with Final Cut Pro, Motion, Premiere and After Effects.

Parameters

Presets

Presets contain a snapshot of your effect configuration. While no built-in presets are available through this parameter, you can still save and load your own preset files.

When you save parameter configuration to a file on disk, this file can later be loaded to recreate the same effect configuration. Presets generated in one video application can be used by the same plug-in running in a different video application.

Working with the Presets Menu

Alpha Source

Lets you provide additional media to the effect.

When no media has been assigned to this parameter, a standard checkerboard pattern is used to represent areas of the screen where your custom media is missing.

The user interface varies by host:

Drop Zones in Final Cut Pro
Drop Zones in Motion
Video Track Selection in Premiere
Layer Selection in After Effects
Auxiliary Media Selection in DaVinci Resolve
