Heh, I have no intention of being in the initial round of beta testing! I explicitly upgraded to an ice lake machine this summer in order to get the best Intel Mac while waiting for the dust to settle.
But I do believe the dust will settle, and I'm optimistic about the future of Apple Silicon.
While a valid workload for a segment, I would be a bit skeptical of generalizing the extraordinary video editing capability to general purpose computing, as those things are facilitated heavily by hardware decoders.
Totally--was not diminishing <strike>A14Z</strike>M1 at all--just to moderate expectations from the quite astonishing video editing capability to "measly" ~2x. Even two year old iPad Pro A12X kicks ass on Clang benchmarks (see Geekbench), although I am not sure how sustained the performance is in that thermal envelope.
I am very curious about the performance.
If the macbook air is editing 6k videos and scrubbing smoothly, I am optimistic.
