Welcome to TVPaint Community forums !

And another one :

That's a beauty!

Is that first one called Suprises? Because your post doesn't show the video, Elodie. Privacy settings are the culprit, I think.

All of it made with TVPaint, if I'm not mistaken:

Yes, animation is made in TVPaint, but rendering is made with... Nuke or AE, can't remember which software they were using.
(I merged the topic with the one already created about AKA works.)
