This is the result we will create, a counter that rapidly ascends from 0 and then slows down to 2580 meters above sea level, above the red-tinted peak of a mountain at dawn. Let's get started. Hello, welcome back to the complete Adobe After Effects series from Cerdas Inovasi Digital. Numbers that count up are often used in infographics and profile videos. Creating it with individual source text keyframes is not feasible, so we will use a slider control and one line of expression.
Create a composition from the mountain dawn footage. Create a text that reads 0 with a bold font at the lower left, then a smaller text for the peak height above it. Source text keyframes can only be hold, so counting from 0 to thousands in this way would require thousands of keyframes.
Select the number text and apply the slider control effect from the expression controls category. This effect does not change the appearance at all, it only provides a number that can be animated in the effect controls. At second 0, activate the slider stopwatch with a value of 0.
At second 3, fill in 2580. Press F9, then set the influence to 80% to make the counting slow down dramatically towards the end.
Open the source text properties, hold Alt, then click the stopwatch. The expression column opens. Type mesh round, parenthesis, slider control effect, parenthesis slider, close parenthesis. This expression reads the slider value and rounds it. Click outside the column to apply it.
Add a unit behind the number by changing the expression to mesh round and then add a space quotation mark mdpl. The text now displays a rounded number followed by mdpl. We will thoroughly discuss expressions in module 9.
Play the preview. The number rapidly ascends, then slows down and stops exactly at 2580 mdpl. Changing the final number is simply a matter of replacing the slider keyframe.
Done. We've already understood the limitations of keyframe source text, using slider controls, animating sliders with e-easing, linking them to source text with the mesh round expression, and adding units. In the next episode, we create kinetic typography. Need a promotional video, logo animation, motion graphics for social media, or visual effects for short films?
