Today I am going to share how to use 2-dimencinal animation to make a ball bounce. This is to help anyone who is interested in 2D drawing to learn the basics of drawing frame by frame. In this lesson you will learn how to use a motion scale, Photoshop, and how to render the video.
Lets begin(:
The Step by Step Process:
- Materials needed: At least 15 pieces of paper, a pencil, computer/Photoshop
- Take out a piece of paper and draw a straight line out the side that goes across most of the paper. This is going to be your motion scale. A motion scale is a helpful tool you use when planning out the motion/speed you subject is doing to the scene
- On your motion scale, begin to make line marks that tell you where you want the ball to be during each frame. In my ball bounce example, I used 15 sheets of paper meaning there are fifteen frames. In the image out to the side, it shows what my motion scale looks like. Each line represents a frame.
- When drawing out your lines on the motion scale think about the motion of your ball and what you want it to do. It the ball being dropped from a height? Is it bouncing off the wall? Or is it bouncing across the screen? These questions will help to plan outlaw the ball will move in your animation. In my example, I made my ball look as if it were dropped and made it bounce up and down. My motion scale shows that the ball slows down when reaching the top (that is why the lines are close together) and then speed up when approaching the ground (that's why the lines are spaced out at the bottom).
- You want to make the ball look realistic like an actual ball that bounces. When the ball bounces up, it slowly comes to a stop when it reaches its maximum height. When the ball starts to fall back down it moves faster the closer it gets to the ground. This is because when the ball bounces up, it is working against gravity which makes it move slower and slower the more it goes up. When the ball moves down, gravity is working with the ball and helping it move. This increases the speed of the ball when traveling downward. Who knew Physics applied to animation!?!?
- Once your done with the scale, start drawing the ball next to the scale's line. Each ball frame must be drawn on a separate sheet of paper so when you pull the pictures into Photoshop and line them next to each other; it will look like the ball is moving and not just one still image.
- When you are done with the 15 or more pictures of the ball, you can then scan it onto your computer.
- Once it is on the computer, open up Photoshop and drag the images of the ball onto the program.
- Then, click the button "Create Video Timeline". This will allow you to start animating the ball bouncing. Once clicked it will open up a timeline at the bottom of the screen showing all the layers you dragged onto it.
- Short each layer of you drawings to one frame each
- Then, drag the layers/drawings into one of the columns in order. This should look something like the purple image below.
- After this, press the play button to the side and watch your drawing com to life.
- Fix any errors you see in the animation.
- Once you think the animation is finished, then go to File-Export-Render Video. Make sure it exports as a mp4.
- The final step is to sit back and enjoy watching your 2D animation!
This is what your ball bounce should somewhat look like in the end.
