The jumping at 0:42 -0:45

and that big jump at 0:58

what are they called and how to do them??

Answer 1

The jumping at :42-:45 are called "on-sha-cots" Im not sure how to spell them but I know how it is pronounced :) The way to do them is to put your feet in 5th posistion  jump in a loose 5th but switch you feet in the air. (ex. Left foot in front, !jump!, switch to your right foot in front in the air and land with your right foot in front in 5th)

Answer 2

at 42 on-chra-cot

at 58 tour jete

Answer 3

It is an on-shri-chots! that is when you change your feat on the way up and change on the way down!In fifth position! You jump up and change and right before you land change again!

And the last dance you have to be on pointe!
