Is it for Windows or Mac?I use Davinci Resolve 12, It can do anything that you need to do for free. The only reason to buy the upgrade is if you want to run multiple gpus and output real d 3d. Everything else is in the free version.
It allows for everything, I usually run 5 layers of video/ images/backgrounds. In resolve 14 you are supposed to be able to do more with your audio but that is still in beta and wasnt working well for me when I tried it. Resolve is pro level editing software/color grading. It is what they used on breaking bad and a lot of other movies/tv shows. They sell a dedicated panel(keyboard) that costs like 20 grand.That is how pro focused it is.Does it allow multiple tracks? I almost fell for Movavi until I found out it doesn't. One track per media type. Not cool.
