In definition, prediction means preparing for actions in advance. And you can show audience an animatation to catch their attention of next incident, such as stooping and discharging a stone. Prediction also can make some uncertain feelings. It tells audience that some surely will happen next second while some is still uncertain in longer time. As a credible animatation, it is crucial to predict, because there may be unexpected and perverse accidents without prediction at first. In addition, learning how movements affect our body postures is very important for an animatation designer. Here we go!
1. The image above shows the original position of the character. We cannot see what will surely happen, but we can imagine the next movement he may do. He stands tensely, with hands next to holsters. We can see and control it, so you are a director, you can order this actor to do anything you like!
2. Prediction and make a reverse moving animatation. Insert keyframe in every figure at next movement, revolve and locate character with the free transform tool. Add interpolation and inching when move out, in order to express the tense of his muscles.
3. Sometimes an animatation needs more keyframes to obtain character’s movements and postures. This animatation has four different postures of character, and every one of them applies interpolation and inching.
4. The first step is that one leg leans back and supports entirely body weight. Absolutely it is an uncomfortable gesture. And now it needs prediction.
5. Here we use the envelope tool to add more tense to this character. According to the reality and nature, It certainly should change when our postures move like that.
6. Newton has demonstrated us that every action has its reaction. Keep this discipline in mind, make character’s reverse movements animatation and he can finally reach expected movements in the end. Have fun!
