Start Media Studio and place two video clips in the Timeline, superimpose them (i.e. arrange the two clips in the Timeline so that they overlap).
Now go to the Production archive, which contains the Transition effects / proDAD folder with the Vitascene Transition.
Hold down your left mouse button and drag this transition between the two clips in the Media Studio Timeline.
Now double-click on the Vitascene Transition in the Timeline, this opens the Vitascene dialogue box.
Click on the Options… button. This opens Vitascene.
Choose a suitable transition from the Transition Templates (e.g. Radial+Mask #14). A playback with the selected transition will appear in the Vitascene preview window and, of course, you can modify the transition in Vitascene to suit you.
Once the project has been edited and completed in Vitascene, simply press the F12 key or click on the symbol 
to return to Ulead Media Studio.
This will automatically save the Vitascene project.
