1 00:00:01,150 --> 00:00:08,680 Hi guys in this lecture you are going to understand at 100 percent the concept of motion path and if 2 00:00:08,680 --> 00:00:14,070 you don't please ask all the questions you want to ask in the Q Any section of the course. 3 00:00:14,290 --> 00:00:20,290 It's an important concept and I will be very happy to help you understand the concept of motion path 4 00:00:20,830 --> 00:00:23,630 and it's very easy very simple Don't worry about it. 5 00:00:23,740 --> 00:00:26,460 Just try to notice a few things. 6 00:00:26,490 --> 00:00:33,790 Let's start out create a new composition and I would take 12 80 by 720 and please work with me. 7 00:00:33,930 --> 00:00:36,870 Make sure that the frame rate is 30. 8 00:00:37,030 --> 00:00:42,660 OK this is important because I'm going to talk about the frame rate and then of course make it 10 seconds. 9 00:00:42,660 --> 00:00:46,360 It will do so now that you have your composition. 10 00:00:46,380 --> 00:00:49,060 I want to remind you about a couple of settings. 11 00:00:49,350 --> 00:00:55,690 First if you go to edit if you are in the macula think on the aftereffects you see you go to preferences. 12 00:00:55,860 --> 00:00:58,820 And here you go too general. 13 00:00:58,980 --> 00:01:04,290 Remember there is a setting that you put a default spatial interpellation to Kenya. 14 00:01:04,770 --> 00:01:05,990 What what does it mean. 15 00:01:06,030 --> 00:01:09,780 There are three key words here are the five actually spatial. 16 00:01:09,780 --> 00:01:12,880 It means it is in space not in time. 17 00:01:13,140 --> 00:01:14,960 It's in space not in time. 18 00:01:15,060 --> 00:01:23,460 It is spatial not Templer interpellation it means the interpretation of the motion path or how it's 19 00:01:23,460 --> 00:01:25,560 going to occur and linear. 20 00:01:25,620 --> 00:01:29,810 It means straight lines and not curved lines or circle lines. 21 00:01:29,910 --> 00:01:37,530 So spatial space interpretation and linear make sure this default is checked like. 22 00:01:38,810 --> 00:01:40,660 Within your composition preview. 23 00:01:40,670 --> 00:01:47,920 It's important that you put Tuggle mask and shape path visibility on OK so make sure it's on. 24 00:01:47,930 --> 00:01:53,960 If you can't see the motion but the on that to put it on and off and in the preview please make sure 25 00:01:53,960 --> 00:01:56,560 that the last I can is checked. 26 00:01:56,600 --> 00:02:02,060 This will allow us to see the motion path when we have a preview. 27 00:02:02,110 --> 00:02:07,440 Let's create a motion through space and time that is spatial and temporal. 28 00:02:07,720 --> 00:02:10,330 Nice terms but they're going to appear in after effects. 29 00:02:10,330 --> 00:02:11,490 And you're going to use them. 30 00:02:11,830 --> 00:02:13,940 Let's take for example a circle. 31 00:02:14,020 --> 00:02:18,380 OK click on the stool click and drag and create the circle. 32 00:02:18,760 --> 00:02:21,210 So the anchor point jumped in the middle of the circle. 33 00:02:21,220 --> 00:02:24,880 If you don't have it use the anchor point door to bring it in the middle. 34 00:02:25,120 --> 00:02:32,650 If you want to limit through time and space you will need the position that's key from the position 35 00:02:32,660 --> 00:02:33,560 just over here. 36 00:02:34,410 --> 00:02:38,910 And then let's move down the time I will move now in time. 37 00:02:38,940 --> 00:02:41,350 Notice I moved in time for one second. 38 00:02:41,350 --> 00:02:43,180 Then let's move in space. 39 00:02:43,180 --> 00:02:43,870 Here you are. 40 00:02:44,080 --> 00:02:50,680 So when you moved in time and you move the space a motion path has been created as simple as this. 41 00:02:50,890 --> 00:02:51,540 Let's do it again. 42 00:02:51,550 --> 00:02:53,170 Let's move to two seconds. 43 00:02:53,170 --> 00:02:53,960 Here you are. 44 00:02:54,010 --> 00:03:00,480 So we moved in time and then we move in space and another leg of the motion path has been created. 45 00:03:00,520 --> 00:03:04,810 This move again in time and less move again in space. 46 00:03:04,870 --> 00:03:06,210 So this is spatial. 47 00:03:06,250 --> 00:03:07,450 This is temporal. 48 00:03:07,620 --> 00:03:10,860 Any new motion path has been created or a new lick. 49 00:03:10,930 --> 00:03:14,950 Let's go to the final one at 4 and move again. 50 00:03:14,980 --> 00:03:15,590 Here you are. 51 00:03:15,760 --> 00:03:18,020 I stop the animation at 4 seconds. 52 00:03:18,950 --> 00:03:26,090 If you skip through now your element or your shape is moving through time and through space that's pretty 53 00:03:26,090 --> 00:03:26,630 good. 54 00:03:26,630 --> 00:03:29,480 So this is how emotion path is created. 55 00:03:29,870 --> 00:03:36,470 Let's look at the special aspect of the motion but first of all you have these big squares here one 56 00:03:36,710 --> 00:03:39,240 and two and three. 57 00:03:39,410 --> 00:03:41,300 These are the keyframes. 58 00:03:41,390 --> 00:03:44,660 That is if I click on this one it will highlight in the timeline. 59 00:03:44,660 --> 00:03:46,270 These are the keyframes. 60 00:03:46,370 --> 00:03:53,620 You can click in space and change the position the special position of this key frame. 61 00:03:53,630 --> 00:03:59,280 So you are changing how you are looking at the path or what will be the path itself. 62 00:03:59,450 --> 00:04:02,590 Nothing to do with time just moving it. 63 00:04:02,610 --> 00:04:07,620 I don't now these small dots here are the frames. 64 00:04:07,620 --> 00:04:10,450 Remember our composition was 30 frames per second. 65 00:04:10,620 --> 00:04:13,280 So here you have 30 dots. 66 00:04:13,290 --> 00:04:13,700 Why. 67 00:04:13,710 --> 00:04:17,790 Because we have one second between this frame and this frame. 68 00:04:17,880 --> 00:04:20,560 There must be 30 frames per second. 69 00:04:20,580 --> 00:04:26,100 Now if you zoom in I will use this spot here to zoom in and to show you frames per second here. 70 00:04:26,490 --> 00:04:29,190 So not this you can jump one frame at a time. 71 00:04:29,190 --> 00:04:29,890 Here you are. 72 00:04:30,060 --> 00:04:31,520 This is Entine Templeton. 73 00:04:31,550 --> 00:04:38,700 I'm going one frame at a time and you notice that also spatially it's going one frame at a time as simple 74 00:04:38,700 --> 00:04:39,320 as this. 75 00:04:39,460 --> 00:04:39,970 OK. 76 00:04:40,110 --> 00:04:49,280 You can use Page Down to move down in the timeline and in the space one frame at a time or page up saw 77 00:04:49,290 --> 00:04:53,690 this is the representation of the motion path frames and keyframes. 78 00:04:53,940 --> 00:04:55,010 There's something else here. 79 00:04:55,010 --> 00:04:56,540 Let's zoom out. 80 00:04:56,820 --> 00:05:00,620 Go back to normal and let's take this keyframe click on it and move it. 81 00:05:00,630 --> 00:05:06,040 But I'm going to move it very neat to the second keyframe nothing nothing has happened in time. 82 00:05:06,150 --> 00:05:11,820 So I still have one second in between the first second keyframe and one second between the second keyframe 83 00:05:12,090 --> 00:05:13,190 and the 33. 84 00:05:13,410 --> 00:05:19,680 But if you notice the space in between the keyframes here is at least visible and the space here is 85 00:05:19,680 --> 00:05:26,670 totally not visible which means it has to traverse all these frames in one second is going to go speedy 86 00:05:27,150 --> 00:05:29,560 and all these frames in one second. 87 00:05:29,580 --> 00:05:30,890 So it's going to be slow. 88 00:05:31,010 --> 00:05:31,640 Let's try it. 89 00:05:31,650 --> 00:05:34,130 If you don't believe me you do not. 90 00:05:34,560 --> 00:05:38,070 This is the special visualization of the motion path. 91 00:05:38,190 --> 00:05:40,450 And you can come and throw it the way you would like. 92 00:05:40,470 --> 00:05:44,770 That will be very interesting to draw motion path very easily. 93 00:05:44,880 --> 00:05:50,550 You really don't have to hire us to go to the keyframe let's look at the temporal aspect here. 94 00:05:50,600 --> 00:05:55,740 I take this keyframe and that it towards the next keyframe. 95 00:05:56,230 --> 00:05:58,790 That's what's going to happen in the motion path here. 96 00:05:59,020 --> 00:06:05,530 So obviously in the timeline here I know that I have more time in between the first and the second than 97 00:06:05,590 --> 00:06:08,040 in between the second and the third one. 98 00:06:08,290 --> 00:06:14,920 And visually I can see that or especially if you like there are more frames here and are new to each 99 00:06:14,920 --> 00:06:18,820 other meaning this animation is going to be somehow slow. 100 00:06:18,820 --> 00:06:19,530 Be careful. 101 00:06:19,550 --> 00:06:21,130 I could have 10 seconds. 102 00:06:21,130 --> 00:06:21,640 OK. 103 00:06:21,790 --> 00:06:24,410 But this one is surely very fast. 104 00:06:24,430 --> 00:06:24,980 This play 105 00:06:29,130 --> 00:06:29,750 up. 106 00:06:29,920 --> 00:06:37,120 So actually this is all about the motion path you create it through movement in space and movement in 107 00:06:37,120 --> 00:06:42,940 time using for example the position in the next lecture about interpellation.
