On the world-editor-tutorials section here is what I found.

Art - Animation - Blend Time (seconds)(Real)

The amount of time it takes a unit/building/hero to blend from being visible to being invisible, and vice versa. If the unit/building/hero has been assigned an ability such as Shadow Meld, this field will apply to it.
