Although Flash and after effects are both computer software – animation done in these tools are considered “traditional”, or “classical” in a way – mostly because all animation today, whether hand drawn, photographed or computer generated – go through a computer for their final process of stitching the frames back to back, to create the sequence. That, and the fact that despite their being “computer-generated” they are not considered CGI (Computer generated Image) – which usually refers to 3-D animation.
In fact – Flash and after effects works as a combination of cutout animation and classical animation – except they are “vector” based animation making motion based on computer generated movement, rather than hand-drawn or moved key frames and in-betweens.
