Laptop for video editing / video editing?

What exactly is to be considered?

I would say a fast processor, enough RAM and a large hard drive, at best SSD.

CPU and RAM = faster rendering

Hard disk = enough space

I would say what I notice when cutting ^^

Big screen, high resolution, 4K would cover a lot, big ram, correspondingly CPU in the upper performance readiness. If you don't like a large screen, the output via an interface should be 4k in the best case 5k
