Install i movie on OS X Yosemite 10.10.5

Hey !

I've got a 2001 macbook pro with OS X Yosemite 10.10.5 , I would like to realise some video montages. I thought that i can use i movie. So when i go on apple store i just find the youngest version. And this version need at least OS X 10.12.2....

I didn't find any solutions on internet... I would like to keep my computer because it's very fine ! And find the good version of i movie... I can't buy a new macbook just for that !

If you have any ideas or maybe some links on internet where i can download the right version , i will be very thankful ...

You are my last chance ...

Thank you so much .
