1 00:00:01,680 --> 00:00:08,520 Guys in this lecture we wanted to explore that trace path and you will notice how amazing is going to 2 00:00:08,520 --> 00:00:15,110 become to use this kind of motion graphics and extremely useful when you're doing bath or masks on videos. 3 00:00:15,210 --> 00:00:19,360 But let's take a very simple example what is the trace path. 4 00:00:19,630 --> 00:00:26,130 Let's go to our player and select our path and create a trace path. 5 00:00:26,140 --> 00:00:27,770 Let's click on it. 6 00:00:28,000 --> 00:00:30,490 There's a new layer has been created. 7 00:00:30,580 --> 00:00:32,640 This is now 50 for me here. 8 00:00:32,710 --> 00:00:38,940 If I press Enter I'm going to call a trace path or trace the way you like. 9 00:00:39,280 --> 00:00:43,740 And let's go now and see what happens inside the trace path. 10 00:00:43,910 --> 00:00:50,080 Non-ladder you will notice now there is an effect and in this effect you have trespassed effect. 11 00:00:50,150 --> 00:00:53,810 Double click on it and it will open in the effect control. 12 00:00:54,070 --> 00:00:56,680 You will not that is progress and Lupica. 13 00:00:56,890 --> 00:00:58,930 Well that's pretty interesting. 14 00:00:58,930 --> 00:01:01,560 And you have to keyframes over here. 15 00:01:01,570 --> 00:01:02,790 Let's drill down. 16 00:01:02,800 --> 00:01:04,690 We have these two keyframes. 17 00:01:04,930 --> 00:01:11,980 If you scroll through you will notice that the null layer is moving along the path itself or the line 18 00:01:12,010 --> 00:01:13,380 or our graph if you like. 19 00:01:13,540 --> 00:01:15,980 But also there is something else that is amazing. 20 00:01:16,210 --> 00:01:19,300 You'll notice that it is oriented according to the path. 21 00:01:19,470 --> 00:01:22,130 Here you are not going to change orientation. 22 00:01:22,130 --> 00:01:23,720 Here it is. 23 00:01:23,860 --> 00:01:27,880 So let's attach some graphic to it and see exactly how it happens. 24 00:01:27,880 --> 00:01:31,700 Let's go to our project here and we have the car. 25 00:01:32,080 --> 00:01:35,630 Then I will take the car and drop it inside the composition. 26 00:01:35,650 --> 00:01:38,150 It's a very big car that's cool. 27 00:01:38,350 --> 00:01:40,840 Now presented to the trace path. 28 00:01:40,990 --> 00:01:48,920 Our click on the week but our press shifted to make a jump to the position of the lab itself. 29 00:01:49,120 --> 00:01:50,420 So it jumps over here. 30 00:01:50,470 --> 00:01:51,710 It is upside down. 31 00:01:51,790 --> 00:01:54,210 You'll see why it's upside down later on. 32 00:01:54,280 --> 00:01:56,210 But then we can open the car. 33 00:01:56,200 --> 00:02:02,850 Now the scale I make it for example 30 percent on the cut is still upside down. 34 00:02:02,950 --> 00:02:06,050 But if you step through as soon as you start here you are. 35 00:02:06,070 --> 00:02:09,460 It is in the direction of the orientation of our path. 36 00:02:09,610 --> 00:02:14,320 Good to rectify this if you like just a couple of frames from here is no problem. 37 00:02:14,470 --> 00:02:17,720 Here you are it shows like it is completely straight. 38 00:02:18,140 --> 00:02:19,180 OK. 39 00:02:19,360 --> 00:02:26,680 Of that if I press space but now notice how the car is going very fast along the path and not is the 40 00:02:26,680 --> 00:02:28,470 orientation is already fixed. 41 00:02:28,480 --> 00:02:35,100 Imagine how much work it has saved you or you already have the whole motion and you could lose. 42 00:02:35,120 --> 00:02:40,280 If you're doing some animation or some presentation you are really done. 43 00:02:40,300 --> 00:02:42,090 And it's pretty nice. 44 00:02:42,110 --> 00:02:49,860 Guys let's look at the spot itself and we said we have an effect here and we have two key frames I want 45 00:02:49,860 --> 00:02:52,450 you press space bar to plate. 46 00:02:52,450 --> 00:02:59,440 Now if you take the time or the last frame if you like and make the time longer notice how it goes now 47 00:02:59,830 --> 00:03:00,880 much. 48 00:03:01,160 --> 00:03:01,950 You are. 49 00:03:01,960 --> 00:03:06,690 You can even make it mass you know slow you are. 50 00:03:07,090 --> 00:03:12,340 OK so these two key frames are determining how the progress is. 51 00:03:12,430 --> 00:03:19,540 If you take it now very near you have some crazy animation going guys let's take it to two seconds. 52 00:03:19,600 --> 00:03:20,390 We are here. 53 00:03:20,560 --> 00:03:21,900 That's pretty cool. 54 00:03:21,900 --> 00:03:24,550 The loop here is going to loop these two keyframes. 55 00:03:24,640 --> 00:03:28,420 If you pull the loop off if you are it sticks to the end of that it does. 56 00:03:28,430 --> 00:03:29,120 Right. 57 00:03:29,170 --> 00:03:29,820 OK. 58 00:03:29,830 --> 00:03:33,830 Or simply you can take this keyframe put it in the end if you like too. 59 00:03:33,970 --> 00:03:36,590 And if you play it's very slow now for us. 60 00:03:36,730 --> 00:03:44,290 But the car will come at the end of the path when the time is over all the animation is over here you 61 00:03:44,290 --> 00:03:46,470 are pretty cool right guys. 62 00:03:46,600 --> 00:03:49,120 So imagine how much saving you have. 63 00:03:49,120 --> 00:03:52,530 First of all you forget about the orientation oriented path. 64 00:03:52,540 --> 00:03:58,900 If you remember and you forget about the loop out expression it's already all done for you. 65 00:03:58,900 --> 00:04:03,690 Of course this is a naive animation but it's pretty cool guys don't you think so. 66 00:04:04,090 --> 00:04:07,800 So this is about the trespass as simple as this. 67 00:04:07,960 --> 00:04:12,770 The applications here are very many and trespass can be very useful. 68 00:04:12,970 --> 00:04:15,100 OK guys thank you very much for listening. 69 00:04:15,140 --> 00:04:16,510 I'll see you in the next lecture.
