I've used proDAD Vitascene LE for a couple of months now and am satisfied for the most part. It's a handy software plug-n to apply quick, contemporary-looking video transitions or effects.
One word of warning though. Registering the software was a nightmare. It took ten days AFTER I paid for the product to get the company to send the correct info to get the plugin properly registered.
I'm understand the need to thwart software theft, but paying customers shouldn't suffer delays and inconvenience as a result. Anyway I hope my experience with proDAD wasn't the norm.
