First let me say, the French ( especially Canada, being that they get funds from the government ) have been making many animations for years, and this is not new at all, for the French
I took up animation in college, chances are they are using a flash based program. However
you do not need FLASH to do an animation like this. You can even use photoshop/GIMP stand alone. Watching this you can see their are not many scenes that are animated, but mimics animation, nothing new I have seen from class, or from the many flash animations, I watch periodically. Nothing new, at least to me.
About FLASH in general. There are many programs, that abuses Flash, because the programmers are lazy and makes money, making FLASH more easier for animators to understand.
If you see the side node, that is a lazy animator, abusing the motions, of the characters, Meaning they want a natural looking motion, but instead they create something that is unnatural. However for the producers and children watching the animation they do not care at all, as long as it makes money and bring in audience
The example that was posted in this thread, an digital camera was used to take a picture, and all of the animation is hand drawn folks. All animation is hand drawn folks, including the animations made inside of a computer.
In my opinion, I am not going to state my opinion because another artist can not compare to another artist. All I can say, hey good for them, great work, hurray, I wish them good luck in their progress.
