In his conclusions though he literally says he doesn't recommend a couple of the higher end Ultra builds, at all, for any video editing, based solely on a few export tests. I agree that viewers need to be aware of the context of any reviewer's opinions, but he can also stay away from giant blanket statements based on a few preliminary tests (of course that means he loses some click-bait, and it's hard to fault someone for playing the click-bait game when it's a click-bait world). He also plugs an as-yet-to-come, more in-depth video editing review (which might not even lead to the same conclusions as this superficial shoot out).
What I'd like to see is more real world observations, such as when video editing does the app start to feel sluggish once you have a bunch of GFX, streams, filters, etc., in the timeline/project? How does the computer perform when you are exporting and editing at the same time? Or when you are jumping between multiple open apps like PS, AE and your NLE? I know they did the 8K export test, but what's the experience like of editing it? Can you zoom around the timeline w/o lag? Does it still playback smooth as glass once you start adding graphic overlays and color correction? I know that takes more time/effort than just running benchmarks/speed tests, but it also gives a better picture of the user experience and how the app actually performs vs just how fast it can export/render.
Doing a computer review mainly based on export, render times is like a doing a car review based solely on the 0-60 time and ignoring handling, cornering, braking, road noise, ride comfort... basically the entire car driving experience.
