So are you using it and it's amazing in your opinion?
You tell me. You saw the various examples… no? You have it yourself… no? Then I don't really understand the question. Not everyone has the same definition of "amazing".
And as I say in the video, the results depend on a
multitude of criteria and variables. The subject matter, amount of speed reduction, etc. It won't
always be amazing. It may
never be amazing… for you… since there is no
one answer and the quality of the results is almost entirely subjective.
how much improvement going from an M1 Max studio to an M2 Max?
You may or may not see a difference in speed, sure. But we're talking
seconds, not minutes. So I don't really understand that question either. And since it all happens in the background anyway, who really cares? Are those few seconds worth a
multi-thousand dollar investment to you? Then go for it. No one else can answer that question but you.
And if you need it for >4K then you
have to have at least an M2, yes. Or you simply transcode whatever it is to 4K first. So again… I don't understand the point behind the question(s) since you already seem to have as much information as you need, by virtue of the video alone.
