Introduction
This is the result we'll create: a ball that keeps bouncing, a board that swings back and forth, and a windmill that spins endlessly. Everything comes from 2 or 3 keyframes and one loop out expression. Let's get started. Hello, welcome back to the complete Adobe After Effects series from Cerdas Inovasi Digital. Many animations are repetitive, bouncing, swinging, or rotating. Instead of keyframing dozens of times, we create one cycle and let the loop out expression repeat it.
Step 1: One bounce cycle
Create a composition from a cloudy sky footage and make an orange circle named bola. Press P Create position keyframes at 0 seconds above, 0.5 seconds below, and 1 second back to the top. Select all and press F9. One bounce is complete, and then the ball stops. Alt-click the stop-up position and type loop out ("cycle").
Step 2: loopOut cycle
After the last keyframe, After Effects repeats the cycle from the beginning again. The ball now bounces forever, even though it only has 3 keyframes.
Step 3: Pingpong swing
Create a wooden square named papan and move the anchor point to the top edge using the Pan Behind tool. On rotation, create a keyframe of minus 20 at 0 seconds and 20 at 1 second. Type the expression loop out ("pingpong"). The board swings back and forth like a pendulum.
Step 4: Offset rotation
Create an 8-pointed star named kincir. On rotation, create a keyframe of 0 at 0 seconds and 90 at 1 second. Then type loop out ("offset"). Unlike cycle, which returns to the beginning, offset adds a difference in each cycle. 90, 180, 270, and keeps increasing.
Step 5: Reading the graph
Enable the expression graph on the kincir rotation. The dashed line after the last keyframe shows the result of the loop out. Keep going up like a staircase. On the graph it goes up and down like a wave.
h Step 6: Preview
Play the preview from the beginning until the 6th second. The ball bounces, the board swings, and the wheel spins continuously. To change the speed, just drag the first cycle keyframe.
Done!
Done. We have created one keyframe cycle and then repeated it using loop out cycle, ping pong, and offset. as well as reading the result of the expression graph.
