Templates and plugins are created for a specific platform so they can only be used in that specific app. Motion templates are an exception to this rule because they can be used directly in Final Cut Pro without any further modifications. Though, you'll get 35% for the purchase of the same product you own on different platform.

Products that are based on video clips (our compositing packs and pre-rendered elements), as well as mLUT packs, can be used in many different editing apps.
