What does it mean by compositing in video animations

An animation video unlike the other simple videos take a lot to create one. Any animated video is usually created by taking different visual elements from other sources to create on single image. This process is called the Compositing. When someone asks that. “How can I make a animation video”, he or she must know that it is not an easy task. You have to create scenes first and then combine them. Then use special effects that cannot be created naturally, which are produced with the help of digital image manipulation (that we also know as Compositing). Have you noticed how unnatural things in videos happen so smoothly?
