Virtix Cinematic for Mac

From Virtix, Inc.:

Virtix Cinematic is a collection of 29 iMovie transitions, much like the transitions used in many classic films. Included are circular, rectangular, and square iris wipes; clock, corner, and edge radial transitions; straight wipes, angled wipes, and fades.

Cinematic allows more options for iMovie transitions, including several new fade types, softness controls, ripple controls, and the abilitiy to position the irises at any point in the screen.
In version 2.0 we introduced 5 new sophisticated transfer modes, nearly doubling the number of possible transition looks. The new options are Burn Through, Fog, Smoke, Sparkles, and Stained Glass.
