Wax can create 2D & 3D special effects and can work in two modes – as a standalone application which would appeal for home users/beginners, and as a “plug-in” to video editors/NLEs which would be more useful for professional editors. Currently Wax can work as a plug-in with Sony Vegas, Pure Motion EditStudio and Adobe Premiere and work for integrating with various other NLEs is in progress.
