There are various things that one needs to keep in mind in order to create an engaging animated explainer video.
First of all, it should be short and not longer than 90 to 100 seconds. Instead of going around the bush, they should directly tell the message.
Secondly, the animated explainer videos should be appealing to the eyes and the ears. They should have bright colors and motions to attract the attention of the viewer instantly.
Thirdly, a good story should be woven around the message to keep the viewers glued till the very end.
