Hello and welcome to this tutorial where I want to teach you how to design transitions in After Effects. Hhow to make them reveal themselves. Ill also show you a real example how you can either use them and how to render the project to use it outside of after effects. A lot of interesting stuff to cover so let us start! At first I want to create a new composition i'll hit the new composition button and I'll create an HD composition 30 frame rate with five seconds duration. This time we will work with the polygon so go to the two-step click and press on the rectangle tool and select the star tool. I select the star tool and I'll try to create a star in the middle by holding the shift key I make sure that it will have perfect proportions. Alright this star doesn't look as good but we can always go inside the pole star and change things up. Now select the color you would like the transitions to have for example I'll prefer to to go a deeper blue maybe a navy blue like that this will be all right. Now I can adjust the polystar at first I would like to open the polystar run and the polystar path and definitely make more points for it. Because I want a completely different look let's maybe make 12 or 13 points, this will look optimal for the things I want to achieve. Now I want to make this slightly bigger here on the edges, we can adjust the size of it by working with the inner and outer radius of the polystar I'll adjust the inner radius to an amount of about 270, this should be ok as I look on it here and the outer radius I'll race to about maybe 500 maybe 550 will be ok we can always adjust this later. Now watch how amazing it is to work with native adobe after effects tools within the program. This being a polystar doesn't mean we can add more things to it and that's what shape layers are all about we can add for example an ellipse on top of it. Now I want to make sure that it will be within the polystar one because i want to merge them so I select the ellipse I just created and move it into the polystar now I can click on the ellipse, I have the ellipse pad here I will open it and I make its size bigger to about this degree. Now we don't see it yet because it is not filled out to make it filled out I need to move it above, above the stroke and above the fill because else because else the hierarchy would not work. The hierarchy and after effects is from top to bottom. I have an ellipse created but I want to intersect those those objects here so once again i click on ADD and now I add the merch path, I put the merch pad right behind the ellipse fat I opened it up and select the mode instead of add to intersect now we are getting closer to the object we want to achieve I still would like to have filled those items here so i need to add one more element and that's really beautiful to work like that because you can add vector items within the software, so I click on the merge pad because i want to edit behind it. Add another ellipse. The ellipse should be behind it because I don't want it to be merged I want it to be added and I work with the size size should go about here and i believe we have our object ready if you need any adjustments always go to the polystar and we can change the sizes so they will be looking a bit different this is the object. I want to work with go into the timeline and close everything down now I want to make sure that it's perfectly in the middle. I click on the object I go to my align panel and I select this icon and this icon to Center it if you don't see those icons and you can find the alignment tab. Now we can finally work on the transition, I'll open up 'S' scale and by pressing shift key I also press are for the rotation on the scale and the rotation. I'll set keyframes at first the scale should be 0% and depending on how long I want the transition to take place it at about one second and 50 frames, we can see it here, I want this scale to be much much bigger so it covers the entire screen. Apparently it's about four hundred percent while doing so I also wanted to rotate maybe 180 degrees so it's not too quick not too slow let's preview the animation. Yes this looks pretty nice! Now what we have to do this will be really simple because we can click on the shape layer click ctrl or command if you are on a Mac D D D, so we have four objects let me go a bit forward. The second object will be placed in the right corner. The third object will be placed in the left corner and the last one will stay in the middle just as the first was. Please select the second and the third and maybe change their colors just so it isn't so boring. I'll stay within the blue range just so it's slightly visible that those colors are different I press ok and this is how this animation basically would look. That's a bit too boring. So we need to stagger the layers. I'll select the layer, press the left all or option key and I select page down one, two, three, four, five, six, maybe seven frames forward this will be ok. I want to be somewhat precise here so it looks cool. 1234567 all of them by pressing you have the same key frames so we don't have to animate it manually because we animated it in the beginning. Now we see how this transition will look and the animation is already very interesting but we lack some closure. I'll show you a great trick on after effect. Select all those layers right click on them click on pre compose. I'll call this composition transition animation I have this transition animation now we have all those objects within 1 composition you can always go back and change things up here click on this precomposed composition and click again ctrl D to duplicate it i'll call this by pressing enter I can change the name of this layer I'll call this reveal and I'll show you why. Because I can place this forward by making sure that most are visible by clicking the second button here you can use the modes I'll select the mode silhouette alpha. What silhouette alpha does it reveals the layers with the layers so as the animation the second animation will start here, it will start to reveal itself. I see this is too close we can go forward. Ok and now we can preview are finished transition. Ok this looks really beautiful you can go with forward so it isn't so quick so the video has time to reveal I would even I would even risk to go a few seconds forward. And this is a perfectly prepared transition we can use for any video i'll check when the transition ends at about three seconds and 50 frames this transition is finished so I press composition composition settings and I change the duration 3 seconds and 50 frames and this is a perfectly prepared transition for use in any video. Now you can select those two pre compositions and pre compose them once again I select a shortcut ctrl shift C but you can also right-click in pre compose use this animation this is a ready composition you can use anywhere. Let me show you an example how easy it is to use such transitions i've imported some example footage and let's say you are working on the video you're doing something and you want to reveal one video with another video. So i have video number 1 and video number two I place this one forward and the first video is playing and then the second appears because i'm editing something. I can transition between them by simply dragging and dropping use this animation here place it as the first one, so it will be visible, and place it in the proper moment and that it already the first video place the transition effect appears, so sorry for the sound I need to mute it, and then the video is revealed. If you want anything to for example be quicker take less time. I can right-click time>enable time remapping by having time remapping enabled I can't I time remap take quicker to play you see it will end here, so I place it a bit forward and now I can preview once again the effect the first video place the transition goes in and the second video is revealed. Also a cool thing is that you can double-click on to use this animation you can add it to the render queue by selecting composition at to render queue and in the output module you could select quicktime video and in the channels RGB + alpha this will render a transparent video a transparent video which could be used in other software, because this animation as you see by this it's transparent i can toggle the transparency to showcase what I mean so it can be rendered and used outside of after effects. This is like the core, basis of creating transitions in after effects since you now have the basic knowledge about how to design such transitions I hope you will be more interested in after effects and would like to learn more if you will be curious how to design more of such transitions I can follow up with the next video showing you cool designs and ideas my name is and Andrzej
