Remember the flip book you played with as a kid? With a stack of white paper, draw some patterns, turn the pages quickly, and you can see the picture "moving". In fact, a book is the simplest animation.

The principle behind this animation is this: due to the reaction time of the human optic nerve, the human eye will produce a "persistence of vision", which means that the picture before about 0.1-0.4 seconds will be retained, so when the frame rate is above 10fps , people can see a coherent picture.

If you want to make an animation book by yourself, FlipaClip is the way to go.

First, you can select or import a background image, and then draw the content of the first frame. The APP provides four brushes, and the size, color and transparency of the brushes can be adjusted. If the next screen is only slightly modified, then you can directly copy and paste the previous screen, which can avoid a lot of repetitive work. You can also use different layers to design the actions of different animated characters. Use the wireframe tool to select and move objects as a whole, and you will see the afterimage of the previous image when you modify it. After completing the screen, remember to click the music button in the lower left corner to dub your composition.

Finally, click the play button, and you can see the image you draw in action.

Although the production process of a real animation is far more complicated than making a flip book. But it does not prevent us from experiencing the fun of doing animation by ourselves in "FlipaClip".
