Excellent editing software

There are 5 years old, I bought the SR11E camcorder and at the same time the first Sony software that disappointed me a lot because despite buying a Blu-ray ROM gave me no satisfaction and especially no Bluray. Time passed, I used my camcorder with another software but without much conviction. But while I was surfing on the Amazon site, I "fell" on Sony editing software and seeing the 2 excellent comments, I decided, and procured me the Sony Movie Studio Platinum 12. And then, oh joy, I managed to edit my first Blu-ray and I'm on my third film medium. Operation is one little clearer and the more you have the tutorial that you can consult at any time. Frankly I recommend it.
