you can create some really cool transitions using your motion graphics techniques in after effects like this one, this sort of circular round radial transition and this is done with some trim path animations all within one single shape layer, which is really cool. So let me get out of here and I'll show you that the way that you would use this is you can export it and you can use it in a program like premiere pro or within after effects. You can line it up so that you have two clips right now. I'm just using this puppy and then the drone shot From the video folder and it cuts from 1 to the next. Cool, so let's go ahead and create this from scratch. So start a new composition. I'll call this transition to For the width and height 1920 by 1080 for this, it's very important to make sure that it's the right size for your composition for the video that you're working with. The way that this works is that we go ahead and create one of these sort of reveals of this circle on and then off and ...
then we duplicate it. So how we do that is by taking our ellipse tool turning off the fill so that there's no fill. So click the fill text right there, turn the fill to none, turning on the stroke so we can play around with the size of this later and we can change the colors too. So for this one, let's start with sort of like a highlighter green and then let's just create a perfect circle so it doesn't happen to be too big. That's pretty good. Let's put our anchor point in the middle, so take the anchor point, make sure we select our shape layer and then drag and I'm holding the command button down so it snaps to the center. And then let's put this in the center using the align panel of our composition. So to create the trim paths, animation go into the add button under the shape layer, click add and choose trim paths. And let's move this trim path into the ellipse by clicking and dragging it into the ellipse. Now open up the ellipse and open up the trim paths. Now you can see if I drag the end percentage it reveals on or off. So let's go back to our transition and you can decide if you want it to rotate on Counterclockwise or clockwise if you want a counterclockwise, just set the end to 100 And then the start percentage set to 100 and then we'll animate the start from 100-0. So set a key frame here At the very beginning for start at 100 and then let's just go to one second and animate on 20. Another thing I wanna do is going into the stroke options of this ellipse, I can change this stroke line cap from a butt cap to a round cap that makes the end of the line round which I think looks a little bit more fun and a little bit more funky. I'm going to increase the stroke with Just like 2 50 or so. So now we have this animating on but we want to have it animate off as well. But for our transition to work we need to complete this circle before it starts animating off. So the way we're going to have an animal may off is the end. So it's going to go from 100-0. Okay, so here at one second once it animates on said the end percentage to 100% instead of key frame Then go to two seconds And then animate the end percentage to zero. So let's bring this in and now it animates on and then off, let's easy ease these so select all of them right click choose easy, Easy going to the graph editor, make sure you're on the speed graph, Select your key frames and then drag the left ones in and the right ones in as well. So now it pops a little bit more which I just tend to like. So one thing that you can play around with is if you shift the end percentage key frames to the left, you can get some really cool animations so it pops on and while it's popping on it starts to pop off which is kind of cool. But because we have to complete the entire circle basically we need everything to be all the way on before we start revealing to make this transition work we need it to go 2 100% and then start revealing the other way. Okay so now we have our one ellipse and then we just basically have to repeat this. So let me show you a quick way to do that. So let's go to one second. Select your lips and then press command. D. Control D. If you're on a Mac or on a pc. Rather now open up your ellipse too options. This is very important to understand what we can do is decrease the size of this ellipse. But I don't want to do that under the transform properties. I want to do it under the ellipse path properties. Now let me tell you why. But first take your ellipse tool, make sure you have the ellipse to selected click the stroke color and let's just change it to something else. So pink. So now the ellipse two is on top of the ellipse one. If I decrease the size in the transform properties, look what happens? The stroke becomes skinnier as well. I don't want the stroke to become skinnier. I want the stroke to say stay the same if I bring down the size of our path. The stroke stays the same with let me zoom in here and basically what I want to do is I want to decrease the size until it's just barely overlap just like so cool. So now both of these, If I zoom out again, both of these are animating on kinda cool. Right, okay, so let's duplicate this again. Now I know this is a little tedious but it's going to get quicker as we select ellipse too or three rather. And let's change the color, something like I mean like a blue go into the path settings, decrease the size and it's barely off. Cool. Okay so now we have our three colors that are repeating And same here we had the three colors. What I want to do now is group these three layers into one group. So by clicking the add button we can create an empty group and then put these three ellipses into this group so I can take these three lips is dragged them into the group. And now what I can do is duplicate the group, Boom! Mind exploded. Right? So let me duplicate the group one, press command D. And now if I take the now transform properties of the group, I can scale it down whoops. But it's scaling down from the right hand side. I want to make sure that it's scaling down from the center. So let me make sure that the anchor point of this group itself is in the center. So I see that if I click the group, it has this anchor point over here which I can click and drag the problem is that with this anchor point of the group, I can't press the command key to snap it to the center of this layer, what can help me though is if I bring up the title action safe. So I know exactly where the center of this composition is because I know that the center of this circle is where the center of this composition is. So again let's take our pan behind tool. And now for the group, let's put that right in the center like so so we zoom in here as much as possible. You can see again using the pan behind tool. I'm going to put it right in the center. Cool. Now let's see what happens when I scaled down. So let's fit 100 if I scale down the group now that now we're talking so I'm just going to scale it down right there. Cool. So that's gonna be group too. Let's duplicate this one and for this one I'm going to make it even bigger. So let's scale up. So now the strokes of these outer circles are a little bit bigger because we are expanding the scale of them and not just the path, but that's okay, so again, I'm just duplicating until we cover the entire frame And with group five We will be good except for the center. So see we have these all coming on. Pretty cool. What I did with the original one is in the very center, I just created one little circle that kind of fades on right? So instead of just creating a bunch of little circles until it goes small, small, small, I created one. Let's just do one more. So let me actually do duplicate group too. So that's going to be group six but the most inside one and then bring up the properties and scale it down. So let me zoom in here. Okay, that's pretty cool. I mean just a little bit bigger now with this one, I'm going to go into a lips, What is it 3? And I'm going to bring up the stroke size so I'm going to increase the stroke size. I'm also going to take down the ellipse path and make it smaller until it's a full circle like so and then increase the width of the stroke until it fills the whole circle like. So so now it animates on like so cool. So I hope you got that. Basically what I did was I decrease the size of the stroke path but I increased the stroke with. So now it's just this very thick stroke that is kind of overlapping itself and becomes that solid circle. So now let's fit up to 100% and see what this looks like awesome. So In this original one the strokes kind of come on at different times and then they come off at different times as well. The other thing that's happening is the whole thing is rotating, so if I go into our transition, let's close this all down, just rename this transition. If I bring up our for rotation, let's go to one second or let's go to like half a second, so you can see what's happening. And if I rotate this, the whole thing rotates. So from the very beginning I'm gonna set a rotation at zero and then at the very end I'm going to set a rotation at let's say negative 90 and just see what happens that looks like, okay, that looks pretty cool. I like it. Okay, but now I want to stagger each line, so it's coming on a little bit one after the other. Okay, so what I'll need to do is play with our key frames. So I press you to bring up all my key frames. Now this is going to seem like a lot of work to you and it kind of is, but basically we have all of our key frames for the start and then our end over here. So what I wanna do is just stagger them one at a time. Now you could be very specific and say you want the middle one going on very first and then the second one going on second. I like it being a little bit more organic. So what I'm gonna do is just start from the top. Now if I zoom into my timeline, you can see a little bit better if I take and I don't want my rotation open. So don't worry about this rotation right here. But if I take all of these start key frames Like this one except for this top one then move it over one frame, that's what I'm going to do. So and I'll take all these other ones except for those top two, Drag him over one frame, Take all of them except for those top three, I'm just going through and staggering them all on. So each one goes on one frame at a time. Okay, selecting our composition window and the tilde key. I can see kind of that's kind of cool. It starts with the ones on the inside and then it starts with from the outside and goes in and that's just the way that I had the group's layered. So if I press you again and then I open up my contents. You see that group six Is the one from the very inside. Group five is the one on the very outside. Group one is the one on the next inside, so that's how I have them staggered. Okay, so now let's press you again, go to the outside key frames or the end key frames, make sure I can see them all and this time let's do the opposite. So taking all the ones on the top except for the one on the bottom, Drag in one frame and continue and do the same Just leaving the one staggered like so kind of a cool piece of key frame artwork right there. Okay, so here we have everything animate on and then off now if you think this is too fast, what we can do is play with time remapping or we can select all of these key frames and then take the last one on the far right and option click and drag to the right. So maybe we want that like something like that. Hey, that looks pretty darn cool. Okay, so now we have this transition and basically how it works is we take our video clips down here and then we want two and I could drag my transition to the right a little bit until where you wanted to actually appear and what we want to do is have it all go on and then right when it all goes on before it starts revealing, we want to cut this clip so I can just do option right bracket and then take our next shot. Say this drone shot for example and that's going to be underneath and that's gonna start revealing. So let me just drag this to the left to a point like where I want it. So now it's going to be revealing. So puppy transition reveal to our drone shot. Cool. So Again, like I mentioned in the lower 3rd project, I'm going to show you how to export projects like this with a transparent background. So if I turn off of our puppy and drone turn on our transparency, you can see that this has a transparent background which would be important if you want to just take this transition and be able to use over and over and over again in say premiere pro rather than having to bring in your two shots with into after effects and exporting it from after effects. That's a lot of work. I would much rather just have this transition as it's own quicktime file that I can place over any cut that I want in my other video editing application. Cool. But I hope you enjoyed this. It's uh, you know, a very intricate effect, but all in one layer. Isn't that incredible? I think it is. Thanks so much for watching and we'll see you in another project.
