So I want to make some presentations up but I don't want to animate it myself, that takes too long. I'm looking for something free, that has models/characters that can change pose/emotion or at least themed clip art so I can perhaps reuse similar characters.

I DO NOT WANT the "zoom" presentations. I don't care for music or for other peoples voices I can do my own voice overs. In fact I probably will!!

Anyway I like the look of PowToon but it's so expensive...

I want to do stuff like this to talk about things I write in my blogs (to entice people to read them):

I want them to be uploaded to youtube, so the quality is also a super important factor. I'd like 720 but if I have to 480 is not an awful place to start.

Anyone know anything or even a program or have any tips?
