1 00:00:00,630 --> 00:00:07,200 Guys and welcome to this new lecture in expressions if you want to learn a lot about expressions I have 2 00:00:07,200 --> 00:00:13,920 a very special of course that you will teach you everything you want to know about expressions and infographics 3 00:00:14,430 --> 00:00:20,940 of course that of course is direct towards creating infographics but it will manipulate expressions 4 00:00:21,000 --> 00:00:27,060 and teach also a lot about certain precepts that are used to do infographics. 5 00:00:27,110 --> 00:00:35,010 5 For now we want to create this by you know just a simple example and how to manipulate expressions 6 00:00:35,010 --> 00:00:35,820 here. 7 00:00:35,880 --> 00:00:39,130 So when the pie is opening it's a pie chart. 8 00:00:39,480 --> 00:00:41,450 The percentage is incrementing. 9 00:00:41,490 --> 00:00:48,420 Of course you could come here and duplicate this one three four times change a value and having a series 10 00:00:48,420 --> 00:00:54,680 of pies that are coming in and it would be quite some infographics you might add some text and so on. 11 00:00:55,070 --> 00:00:57,660 OK if I let's start let's delete everything. 12 00:00:57,660 --> 00:00:58,640 No problem. 13 00:00:58,830 --> 00:01:00,190 We create a circle. 14 00:01:00,210 --> 00:01:07,380 The first circle is going to be the background circle Pest Control shift and create give it a dark color 15 00:01:07,440 --> 00:01:12,870 for example blue darkish blue that will do I will come to elipse. 16 00:01:12,900 --> 00:01:20,520 I will go to transform my lips and set it in the middle of the composition and also said my the anchor 17 00:01:20,520 --> 00:01:21,970 point in the middle. 18 00:01:22,230 --> 00:01:23,450 That's good fine. 19 00:01:23,460 --> 00:01:25,510 Now I want to create the by itself. 20 00:01:25,530 --> 00:01:31,760 What I will do is to duplicate that layer again and give it a stroke. 21 00:01:31,770 --> 00:01:40,820 So we come to the strong full stroke and make it white and make it a bit bigger. 22 00:01:40,850 --> 00:01:45,380 But not now the stroke in the layer is coming you know outside. 23 00:01:45,380 --> 00:01:51,190 An insult is the 87 or the 90 here is divided into two fixed that. 24 00:01:51,380 --> 00:01:55,390 So let's call this background OK for the PI. 25 00:01:55,670 --> 00:01:59,780 And this is the by itself good to fix. 26 00:01:59,810 --> 00:02:05,810 Here what we do is not to resize it because it will never come you know exactly the same. 27 00:02:05,810 --> 00:02:08,250 We have duplicated these circles. 28 00:02:08,690 --> 00:02:11,750 So what we'll do is to come to content. 29 00:02:11,990 --> 00:02:19,120 We go to elipse and we come to elipse but all in 11:1 and we come and we add a offset path. 30 00:02:19,130 --> 00:02:23,230 Now I have minus 90 the offset is set at 10. 31 00:02:23,240 --> 00:02:25,360 I will make it a minus 45. 32 00:02:25,670 --> 00:02:32,050 And now the two circles are 100 percent you know Center and the PI is looking good. 33 00:02:32,060 --> 00:02:39,410 I can come out both of them and scale them up if I like and click and get them up. 34 00:02:39,440 --> 00:02:41,600 We still have the same five. 35 00:02:41,600 --> 00:02:43,280 Now I want to animate the pie. 36 00:02:43,360 --> 00:02:50,190 For that I will use here the path and I will program the path. 37 00:02:50,210 --> 00:02:53,730 It goes from zero to 100 percent using the end. 38 00:02:53,900 --> 00:03:00,140 So I come to the end of keyframe it make it zero percent come to two seconds for example just to show 39 00:03:00,140 --> 00:03:02,740 you and make it 75 percent. 40 00:03:02,990 --> 00:03:05,510 So now is not working because I need to offset it. 41 00:03:05,510 --> 00:03:07,850 I will offset that with minus 80. 42 00:03:07,950 --> 00:03:10,460 Yup and here we are. 43 00:03:10,460 --> 00:03:17,030 It's moving along the path that all you knew I would come to the text here click in the middle of the 44 00:03:17,030 --> 00:03:19,070 text and right one two three four. 45 00:03:19,070 --> 00:03:26,590 Now put the anchor point of the text in the middle and center right in the middle of the composition. 46 00:03:26,670 --> 00:03:29,580 It was centered in the middle of the circle. 47 00:03:29,580 --> 00:03:31,390 Here you are five. 48 00:03:31,470 --> 00:03:38,080 Now I wanted the text to display the percentage of the opening of the pie. 49 00:03:38,340 --> 00:03:40,070 I will come to Texas. 50 00:03:40,400 --> 00:03:45,940 I will open thanks as usual open source text and pick it to the. 51 00:03:46,140 --> 00:03:48,440 And of course I'm sure you knew that. 52 00:03:48,780 --> 00:03:51,950 I will come and pick me up to the end and here you are. 53 00:03:51,990 --> 00:03:54,260 It's over there but it is. 54 00:03:54,270 --> 00:03:56,850 And we need to make it not that simple. 55 00:03:57,180 --> 00:04:01,120 So I will come to the source text and you know that function. 56 00:04:01,290 --> 00:04:09,720 I want to type it so I type math that around open brackets press and go to the end and close the brackets. 57 00:04:09,780 --> 00:04:13,180 And here you are you have your text coming in beautiful. 58 00:04:13,180 --> 00:04:21,570 Then I want to add the percentage so that is the public what percent of what and call you out. 59 00:04:21,620 --> 00:04:26,680 You can increase the size of the text if you want make it bigger. 60 00:04:27,180 --> 00:04:33,390 Now if you believe you call it's happening very nice you can change the percentage or you have to do 61 00:04:33,390 --> 00:04:39,840 is to come to the end of the path and go to the keyframe for example and check the percentage the way 62 00:04:39,840 --> 00:04:40,320 you want. 63 00:04:40,320 --> 00:04:43,520 And everything will work this political. 64 00:04:43,600 --> 00:04:46,740 Is that the zero appears in the beginning and we don't want that. 65 00:04:46,740 --> 00:04:49,380 So we come to the decks. 66 00:04:49,410 --> 00:04:51,330 We open our placidity. 67 00:04:51,390 --> 00:04:55,250 Now I can put keyframes on the opacity but that will be silly. 68 00:04:55,470 --> 00:05:04,520 Well I will do is to open the expression and go down to the end again and put the end here. 69 00:05:05,130 --> 00:05:07,120 Now the opacity is a function of the end. 70 00:05:07,140 --> 00:05:14,520 If you start it would be at zero because and the zero if you scroll up you will be not 100 percent because 71 00:05:14,640 --> 00:05:17,040 this is going on it's 77 percent. 72 00:05:17,040 --> 00:05:19,660 How do I solve the problem in a very easy way. 73 00:05:19,830 --> 00:05:27,750 I just multiplied the value of opacity by two times two or 1.5 whatever you want provided that at the 74 00:05:27,750 --> 00:05:31,590 end it's more equal or more to 100 percent. 75 00:05:31,920 --> 00:05:34,000 And here you are. 76 00:05:34,560 --> 00:05:36,990 That's a pretty cool one what you can do here. 77 00:05:37,170 --> 00:05:43,950 Usually what they will do is take all this and make Control-C and Contrave now I have the buy two. 78 00:05:44,250 --> 00:05:48,890 I will take buy two and put it here for example and buy one. 79 00:05:49,060 --> 00:05:54,640 But on this side that I want to put it here. 80 00:05:54,730 --> 00:05:57,890 Come here are very nice. 81 00:05:57,910 --> 00:06:04,010 Now I will come to the keyframe select all of them see where the keyframes will go to the end not by 82 00:06:04,020 --> 00:06:04,330 two. 83 00:06:04,330 --> 00:06:11,040 For example we wanted to go to a little bit. 84 00:06:11,200 --> 00:06:17,640 And now there is a problem you notice that a pie one or this pie is still having the value of this. 85 00:06:17,640 --> 00:06:26,690 And so one of the things that I will come to text for this by open the expression I will eat and not 86 00:06:26,730 --> 00:06:28,470 zero of the path one. 87 00:06:28,670 --> 00:06:36,140 Well I must do here is to change for by one two by two and I will put by two. 88 00:06:36,620 --> 00:06:41,100 And here also I want to put by two that work. 89 00:06:41,160 --> 00:06:42,570 Yes it did work. 90 00:06:42,630 --> 00:06:43,460 Here you are. 91 00:06:43,790 --> 00:06:50,090 So now this is the simple changes that you have to do to get a reputation of a certain item. 92 00:06:50,120 --> 00:06:55,810 Now you have a very good one you don't need to compose or to create many things but this will work. 93 00:06:55,820 --> 00:06:58,370 Of course I would not go for one two three. 94 00:06:58,370 --> 00:07:02,530 I will write a text one for example or this one is text too. 95 00:07:02,750 --> 00:07:13,200 And this is the first one and name one I would have done this before and the back one. 96 00:07:14,090 --> 00:07:16,480 So it's very clear what is happening here. 97 00:07:16,790 --> 00:07:23,310 I could also use the index here and we'll see that later on to be able to give the values that I want 98 00:07:23,310 --> 00:07:24,130 to find. 99 00:07:24,140 --> 00:07:25,520 Thanks very much for listening. 100 00:07:25,520 --> 00:07:28,380 I hope this was useful given this pies. 101 00:07:28,700 --> 00:07:34,560 It's very nice and it will help you a lot if you're doing infographics or whatever you're doing a documentary 102 00:07:34,580 --> 00:07:37,220 and stories like this it's quite interesting. 103 00:07:37,340 --> 00:07:41,440 We have used the expression here just to control everything. 104 00:07:41,450 --> 00:07:47,850 If you press you you have only two keyframes and it's enough to change the value of the Laski frame. 105 00:07:48,080 --> 00:07:52,970 So to change the value that's appearing in all the graph and it's pretty convenient. 106 00:07:52,970 --> 00:07:54,280 See you in the next lecture. 107 00:07:54,290 --> 00:07:56,200 And thanks for listening to this one.
