I'm going to assume that you posted this expecting comment.
I want to preface my comment with a quote from your web site, which I think sums up the situation:
I consider myself a technology enthusiast first and a musician second.
This is not a video. It is a song presented with a slideshow as a background, presumably because you wanted to put it up on YouTube instead of SoundCloud.
As a song, and sticking strictly to a technical issue, albeit a pretty basic one, I think that you should have a talk with the person that you got/hired to mix and master this about separation between the instrumental part of a song and the vocal.
Over the last few weeks, you made clear, in post after post, your requirement that the Mac mini meet high, indeed professional, standards, and talked, among other things, about your need for an eGPU and an expansive monitor, and your use of professional applications like Logic and Final Cut. There was complaint after complaint about whether the mini met your working style on issues like Bluetooth range. Indeed, you had one sent back.
Let me point out the reality. This song/slideshow could easily have been produced on the cheapest computer that Apple makes with software that comes free with the operating system.
For me, this is a lesson in how seriously to take, or rather not take, anonymous posters on an Internet forum.
