my main concern from your software is to make videos similar to this one
which tutorial so I can make video where I can squeeze the ball or make the character hold the ball with his hand and look down.
Looks to me like the animator has created his own SVGs and then placed them on top of each other. So has redrawn the boy looking in different directions and then laid the images on top of each other with 0 draw time to show the change in facial expression.
You may find our Create your own images page useful and also this YouTube video which one of our customers has created to walk you through image creation. One of our regular customers also has a forum post on tips and settings needed with SVGs to make them draw well in the application
thank you :)
