Hi Jean-Cyprien,
I love PTE, I first found out about it through the Camera Club, some of the members used it for making their AV for our AV competitions, sadly not enough member entered the AV competition now, only 3 of us last season, so the club has stopped doing that competition.
I like to make AV's with my images for myself it's a nice way to look at them, also to make for special birthdays for family with all the old photographs, There are a few software programs I would not be without and PTE is one of the top three
Thank you
