Still Struggling with Time Signatures Mostly Detecting 2/4

Strange - it disappeared overnight. I put it up again: http://imgur.com/a/281Zn

Okay, but wait a minute: he indicates dotted half for 3/4. Just like the dotted eighth for 3/8 in the beginning. Every metronome marking corresponds to the measure(meter) length. So?

Maybe this complex way ensures smoother transitions?....or easier to slide into?

I think that an eighth=x would suffice for eighth-note meters, quarter for quarter, etc......

Every metronome marking corresponds to the measure(meter) length.

No, they don't.

The meter change right before that marks the beat in the tempo mark, even though a measure of 2/2 is a metric unit, just like 3/8 and 3/4.

Ehhn, ehhn, I ain't never gonna play none of that music anyways. Again, I don't know as we're helping the OP.

Well heavy metal, you've been listening
to 1/4, 1/6, 32, 64 und 128 quintad
und s minor 5'th
from the root
Diminished minor first, first, minor second or slide
I think more so than what you think.

Nothing I listen is into 3/8 time.
