I started to use my new Apple M1 MacMini for video editing with DaVincci Resolver 16. That is not native for M1 yet. But that is still very fast. For 1 Minute 4K video, the exporting time is less than 1 minute. I believe the M1 and the new MacOS is tuned for this purpose. Lastly, the internal hard disk for M1 MacMini is very expensive. I got 512GB Hard Disk, but that is very limited. So, I got Samsung T7 external hard. That is still very fast enough for video editing via thunderbolt, that is about 1Gbits and that is around half price of the internal hard disk
