How do you make a unified styled video theme?

[Shredder_guitar]

Title pretty much says it all.  There are a few systems that i have searched high and low for a unified theme and they just simply do not exist, So It looks like I'll need to create my own. I can create the artworks in photoshop, but, What then?  I've seen a brief mention of someone doing a theme in powerpoint...?  Is that the way? Just not sure how it's done...previously I would create themes in hypertheme...but that is clearly no longer the way and outdated... Just looking for a guide or someone to offer advice on how it's done now. 
The pic is just for visual reference on the style of theme I'm wanting to create.

So I used adobe premier to make this... I know almost nothing about premier...it turned out slightly better than shitty, this is my first attempt in making a theme this way...so be gentle...but it works...posting this in case one of the other 3 people on the entire internet plays these unity games.

This one turned out a bit better. I really dislike making these things. but I do enjoy when they're finished.

Try using Powerpoint, much easier.

Literally drop all assets onto the screen and save video, unless you want all bells and whistles.

I'll have to try it that way...next time and see how it works out... Now that i've done this a couple times, I still have a Sunsoft Theme to make and then hopefully my theme making days are over.
