When you have your final animation built, what is a way for you to add polish and tie everything together? One way is by using transitions. Where can you find transitions in Adobe After Effects and Creative Cloud Market? In this video, author Ian Robinson adds polish to the project by adding transitions.
- Now that we have the core of our animation built, we're ready to add a slick transition or two to give it that final polish and tie everything together. So let's start by looking at our project. And if I grab my current time indicator and scrub, you can see while I have a sliding background, I really only have one graphic that's kind of sliding in and that's this hand. So when it's slides in, the hand clicks and so this is where we want the animation to start. Right here when the hand inverts its colors, which is the second key frame and it's at 1:25.
So I'm just going to press shift two, so I quickly have a marker here. And I'll double-click on that and call it transition. So, whenever you're focusing on a transition, you need to look at the overall project and determine what needs to change. So, first thing, this graphic title needs to change from version one to version two. And then the graphic itself needs to change from the first version of the graphic to the second. So, I'll go ahead and collapse layer one and if we scroll down here, you can see layer seven is my V1 graphic.
And if we turn on layer eight and turn off seven there's V2. Okay, so let's turn layer seven back on and eight off for the time being. And let's go up here to layer three. Layer three says version one and notice I don't have any other texts that says version two. So, instead of going back to Photoshop, we'll just convert this text here in aftereffects. With layer three selected, we can go up under layer and choose convert to editable text. That's one of the beautiful integrations between Photoshop and aftereffects.
Now, select layer three and press command or Ctrl+d to duplicate and double-click directly on the T for layer three, the new duplicate layer. Once you've double-clicked, use your right arrow to move the cursor to the end of the text, press delete, and then press the number two to set the number two. Then I'll go ahead and grab my selection tool here to change it to version two. Now, I want version one to slide out and version two to slide back in, so let's turn the visibility off for layer three right now and focus on layer four.
So select layer four and hold down shift option and then press p if you're on windows or just option p on the mac to open the position shortcut and add a keyframe. Now I'm going to move five frames down the timeline. So I'll just click here in the time and type +5 and let's scrub on the y parameter to go ahead and slide version one off the screen. We'll worry about masking this out a little bit later, but this works perfectly well and now let's go ahead and grab layer three and press alt+left bracket or option+left bracket to trim the start point.
Now turn the visibility on for layer two and then we need to go ahead and move layer two up to where version one is. So to do that, I'm just going to go ahead and select both these key frames and I'll copy them. Then I'll select layer three and I'll pace those key frames. I'll press u on my keyboard. And then, all we have to do is reverse these keyframes, so right click on either one of the keyframes, go to your keyframe assistant and say time reverse keyframes.
So now if we scrub through, you can see version one comes up and then version two comes down. It'll be very quick, if you want to preview, there we go. Now obviously, you can speed this up or slow it down however you like. And just to keep things tidy, I'm going to navigate to my second keyframe here for layer four and I'll select layer four and press option+right bracket or alt+right bracket to trim the out point of that layer. Okay, so we have the texts switching. Now all we need to do is actually slide the background graphic, so I'll collapse layers three and four and let's focus on animating V1.
So, I want the animation to start here at the transition, so let's hold down shift and scrub 'til we get to the transition marker. And then press shift+alt+p on windows or opt+p on the mac to set a position keyframe and open that shortcut. Now this transition, I want to take a little longer, so let's click here in the time and type +15 to move 15 frames down the timeline. And I'll click and drag on the x parameter and I'm going to hold shift as I drag, so it slides out rather quickly.
And let's have it move just off the edge of the phone. That's perfect. Now all we have to do is turn the visibility of layer nine on. So now we see, that second graphic. And then we can go ahead and go to the parent column. Choose the pick whip and point it at layer eight. Now if we scrub through, you'll notice this version is going to follow that version perfectly. So now all we need to do is mask both of these.
Notice the mask layer is here and I only have one layer following that mask. So there are two different ways we could do this. We could either pre-compose or just duplicate the mask. So I'm going to select the mask. I'll press command d to duplicate. I'll move the copy down above layer 10. And then on layer 10, toggle your switches and modes and then make sure to choose alpha matte for mask two. So now when we scrub, you'll see version one slides and there's version two.
So as I'm looking at it, it looks like we need to actually have the text change a little bit later. So as we scrub through here, I could scroll up and select both of my text layers. Just click on one, shift click on the other and just slide them down a little bit. And then we'll go ahead and move. And here you can see, it's going to switch from version one to version two and now we can go ahead and preview this. Okay, so the last thing we need to do is deal with the type that's actually sliding off the screen.
So, in order to do this, I'm going to go ahead and select both of these layers and pre-compose. So I'll go up under layer and choose pre-compose and I'll say Version Text _Pre. Now make sure to select adjust composition duration to the time span of selected layers and click OK. Now we can see where everything starts. And so now we just need to select layer six, our mask layer. You can press command d or control d to duplicate.
And move it up in front of our version text pre-comp. Then select layer four, our version text pre-comp layer. You guessed it, have it alpha matte layer three. And so now, when we scrub through, you can see it slides and then we have each version sliding. So as you can see, when it comes to actually creating your transition, it's all about timing. Make sure to add markers in your timeline and then scrub through. Don't focus on masking until after you have your initial keyframe set up.
Then you can actually go back and polish your animation and smooth keyframes and do whatever it is you'd like to do. The big key is to get all of your animation blocked out first.
