Don't do it.
The adverts are wonderful, promising much. Unfortunately, it's utter tripe. The most infuriating few hours and, yes, waste of money I could have imagined. The idea that you have to pay to correct errors that the AI has made itself - eg. you ask to correct one small thing and it changes the entire shot - is beyond a joke. Never again. I'd rather have no music video at all, but would even more so rather pay thousands to a human with skills than use VidMuse ever again.
