How to Draw An Animated Circle with Adobe Aftereffects
If you want to animate a circle, just like this one in this after effects tutorial, I'm going to show you a quick and easy way to get it done. The first step is we just want to make a new composition. I'm going to go to composition, new composition. I'm just going to set it to the preset that I have here. I'm just going to name it press enter here's my composition. I'm just going to fit it into my window and the first thing I want to do is create the shape.
So I'm going to come up here. I'm going to make sure the ellipse tool is selected and while holding shift in the center of my frame, I'm just going to draw it. The only reason I'm holding shift here is that if I don't hold shift is going to give me lips instead of a circle. So I'm just going to delete that and now we have a layer down here, shape layer one. I'm just going to press that layer, press enters to rename it, and then I'm going to press the V tool. To get my selection tool. I'm just going to move this somewhere in the center here. If your circle is filled, when you created it, you could come up here to fill, select the text itself and just press no fill.
If you have to fill select, it's gonna fill it with a color. So we don't want that here. We just want it to be transparent. So I'm going to press none breast and the fill color here we don't care about. Cause we don't have any fill inside this stroke though. We care about, we want to change how thick the stroke is.
So I'm going to change it to 30 and I'm going to change the stroke color here to read. So I'll just pick red here press okay. So now we have a red 30 pixels stroke. That's layer one here and now to animate this layer. We want to go to our effects on preset and I want to search for a radial wipe. That's the transition radial wipe here.
I'm going to grab that and apply it to my layer and it's applied here to the layer. Now, we need to animate that transition that we just applied. So I'm going to go up here and under transitional completion, I'm going to turn on my clock here to start keyframe and in the beginning, I want it to be transitional completion at 100.
That'll make it blank. Then all move to one second on my timeline and then make the transitional completion back to 0% press enter so now if we go to our timeline if I press space bar and press play are transitional completion starts with zero, and then it goes to 100. Now, if you want this to be built the other way, you could go up here on their wipe and change it to counter-clockwise not as kind of build it the other way.
So if you want a clockwise goes that way, if you want to counter-clockwise change it the other way. Now you'll have an animated circle at this point. If you want to change the shape of your layer, you could do that. You could just grab it and change the layer. If you don't want a perfect circle, you could change it to any shape you want and the transition is going to still apply. I'm going to just command Z to undo that. I'll show you one more quick thing here that could come in handy. You could put another thinner, sir, inside this one, I make a cooler effect here. So I'm going to select this layer and I'm going to come in D to duplicate it and now I have a new circle here. I'm going to name this one, circle green and now if I take this one and I change the stroke to green and I'll change the pixel density to 15 here we go and now I'm going to put it underneath the other layer right grabbing it. I'm putting it under. So you see the red layer first and now I need to offset my keyframes between the two-layer.
So I'm going to press you. That will show the keyframes for both of my layers. Now, if I offset this one here. You see, it's created a circle inside the other circles. So you see the green one going first and then the red one is going second. So it creates a cool effect. If I bring it even further back creates a really interesting effect here.
So you could do this with multiple layers, multiple colors, and really bring this animator circle to life. Now, I could just go to my three-second mark, press N which's my outpoint point for the layer and then I could export add to render queue and to make sure the transparency is still is intact. I'm going to change the channel from RGB to RGB plus alpha.
That'll make sure the transparency behind my circle is there and a press okay and then I could just run the race out to use it on top of any video file to watch more. How to videos go to Howfinity.com or subscribe to our YouTube page. Thanks for watching.
