i been trying to figure out how he got that 15 stack i think it is marker's mark but he went to fast and i even slowed down the video but i can't read it well can someone explain that rotation

So he used full HQ mats and did the following:
MaMa
CZ
PbP
PbP
FS/ToT till MaMa wears
CZ
IQ
SH
WN2
IT/BT/refresh SH
finisher
RS

The Reclaim+Rapid Synthesis finisher made me cringe. He had Steady Hand up but that's still a 30% chance of failing the recipe and a 3% chance of losing your mats even after getting to 100% HQ. Makes sense to do if you find yourself shorter on progress than you expected, but I would definitely not recommend planning a rotation around that.
But yes, the big stack effect at the beginning is Maker's Mark.

woahhh that is scary finishing move. i think with iq at 7 + GS + Innovation is enough to get 100% HQ. Instead of iq at 8 and rapid, can swap with ingen 2 + CS2 X 2.

You mean the 15 stack he got at the beginning? Maker's Mark's stacks are determined by how hard the recipe is, aren't it? You only get those stacks if you use MM as your first move. If that wasn't your question, then sorry. XD
