MacOS will use more memory if you have it available. That will makes things more efficient.
Right now my Activity Monitor is showing that I have 58.91 GB Memory Used, out of the 96 GB. But, the sum of my "Wired" and "Active" memory is only 42 GB. So, MacOS decided to hang on to an extra 16 GB of stuff for the sake of efficiency. If I were to shut down a bunch of applications or end certain processes within those applications, the 42 GB would go down, but the total Memory Used would not go down as much. That would allow me to reopen programs and other things much more quickly. I suppose using those video tools involves running the same processes within them repeatedly; having extra headroom would make that much more efficient.
On the other hand, it's very hard to tell how much you'll notice the extra efficiency and whether it's worth the price. My computer is like lightning when I kick off repeated compiles. But, I have no idea what it would be like with less RAM.
