I haven't done exhaustive research, but the small number of articles I've read suggest that a Ryzen 7 will do a better job of video than the broadly equivalent Intel (the flipside being that the Intel will perform better for gaming, apparently).
What are you using? I've been using Corel VideoStudio 2018 and it's not even fantastic on this machine (an Overclockers Germanium machine I bought back in 2018 which pretty much monsters everything else, eg. CODMW and BLOPS Cold War at 4K maxed out)
