I've learned what is probably the most economical is to find a mid-range gaming computer, either laptop or desktop, for content creation. The "business class" computers with the hardware you need cost almost twice what a comparable "gaming" machine costs.The zoom is rough as the control on my Samsung s23 Ultra is sliding my finger on the screen. And it steps regardless how I do that. I think with a better video editor I could work to smooth that.
Actually this exercise is going to be expensive for me. I literally have 10 hrs of editing on that because of how slow the editor/computer display and processing is. To have an interactive / real time type experience I will have to radically upgrade my computer. I have a gen 6 i7 right now with minimal 16gb ram , I need at least a gen 12 i7-6700HQ CPU @ 2.60GHz 2.60 GHz and a LOT more ram along with a much faster graphics card. Right now the mother board/cpu/graphics speed it simply too slow and the ram & memory on my graphics is not enough.
I built a "gaming" desktop for my son to use to edit his podcasts, and it cost about a third of just going out and buying a creator's version of the same thing.
My current laptop has a new AMD high performance processor, 10GB vram, and QHD+ screen for about a thousand dollars. If you don't want to spend that much, you can easily find "last year's model" for about 2/3 of that, and still have a very powerful machine. Desktops are a lot more customizable and upgradable, but you do need to know what you're doing.
FWIW, my "backup, spare" computer is an older model Alienware gaming machine I picked up for $300 off craigslist. It's got a 17" display, 8Gb vram, and a 6 core i-7 processor. It's probably about 3x "better" than what you're using now.
If you have a Best Buy near you, you can take advantage of their liberal return/exchange policy to get something you can use, and if it doesn't work for you, you can return or exchange it until you find one that will work. Most of these gaming laptops and desktops can have all their "gamey" light shows turned off, and can be used as "normal" machines, but still utilize the high-end components.
If you want to get a desktop, I like the Acer Predator Orion 3000 machine, they're easily found for under $600, and are easily upgradable to do what you want. The newer ones have 11th generation Intel processors, 6Gb vram, and 8Gb ram. Ram and storage are insanely easy to upgrade in it, as well. If you get a refurbished unit off that online auction site, you can get one with a 2 year replacement warranty.
