WEBVTT - https://subtitletools.com 00:00:00.000 --> 00:00:00.033 Edited at https://subtitletools.com 00:00:01.050 --> 00:00:06.280 So now we have our main keys we can actually take a look at breaking this down even further. 00:00:06.480 --> 00:00:11.910 And it's really easy to get overwhelmed with animation and think oh my gosh I have you know we only 00:00:11.910 --> 00:00:16.630 did four keyframes basically because again that last one is mirrored. 00:00:16.750 --> 00:00:21.150 It's the same keyframe as the first frame as frame Fortier's. 00:00:21.380 --> 00:00:24.570 So we're really did you know four poses here. 00:00:24.720 --> 00:00:30.690 And when we look at this animation we have 40 frames when we think oh my gosh I have to do this 10 times 00:00:30.690 --> 00:00:34.530 what I already did you know don't get overwhelmed. 00:00:34.560 --> 00:00:35.850 Well let's break this down. 00:00:35.880 --> 00:00:37.810 Let's drag the timeline. 00:00:37.860 --> 00:00:39.410 This is what I'd like to do. 00:00:39.630 --> 00:00:39.980 You know what. 00:00:39.990 --> 00:00:42.530 Just focus on between two key frames. 00:00:42.540 --> 00:00:43.200 OK. 00:00:43.320 --> 00:00:47.620 Once we have the keys in now we can just take it in piecemeal down. 00:00:47.640 --> 00:00:47.980 OK. 00:00:48.000 --> 00:00:49.500 We just have this motion to worry about now. 00:00:49.510 --> 00:00:51.050 Don't worry about anything else. 00:00:51.100 --> 00:00:52.410 Are you going to get this looking right. 00:00:52.470 --> 00:00:53.330 OK. 00:00:53.490 --> 00:00:57.910 So when you look at this we can think OK this is the extreme pose. 00:00:57.920 --> 00:00:58.220 Right. 00:00:58.230 --> 00:01:02.820 That's the technical term the extreme pose these are the furthest that these two legs are going to be 00:01:02.820 --> 00:01:04.020 apart from each other. 00:01:04.020 --> 00:01:06.160 Those are the extreme distances. 00:01:06.420 --> 00:01:09.650 And when we think about extreme distances we also have to think. 00:01:09.660 --> 00:01:09.920 All right. 00:01:09.930 --> 00:01:12.280 How's this weight being carried. 00:01:12.270 --> 00:01:17.580 Is it if it's a tripod and the weight is very far out there and there's a lot of weight here in the 00:01:17.580 --> 00:01:18.660 center of gravity. 00:01:18.690 --> 00:01:27.330 It's going to want to fall down and while you're walking for these next few frames before this foot 00:01:27.420 --> 00:01:35.250 picks up the weight your body will be going down because basically walking is controlled falling and 00:01:35.370 --> 00:01:38.190 your foot the foot in front is basically catching you. 00:01:38.190 --> 00:01:40.040 Each time that you fall. 00:01:40.290 --> 00:01:47.100 So if that's the case then we can know that this center of gravity which actually made it keyframe here 00:01:47.100 --> 00:01:53.760 is going to delete in my little example there that this key this center of gravity is not going to be 00:01:53.760 --> 00:01:55.170 going up immediately. 00:01:55.200 --> 00:01:55.740 Right. 00:01:55.830 --> 00:02:00.750 Because this foot hasn't had time to really catch the weight of everything yet. 00:02:00.750 --> 00:02:03.890 So what's going to actually happen is this what's going to be going down. 00:02:04.080 --> 00:02:04.590 OK. 00:02:04.710 --> 00:02:08.500 So we can maybe come out here three frames and keep this down. 00:02:08.520 --> 00:02:09.630 I mean it's space bar. 00:02:09.630 --> 00:02:12.960 I have the same set up I had from the previous lesson. 00:02:13.080 --> 00:02:19.170 So I have the graph down here another panel I'm just I just want to go a little bit past where we started 00:02:19.170 --> 00:02:20.140 here. 00:02:20.250 --> 00:02:20.970 Right. 00:02:21.360 --> 00:02:26.190 And the other thing we need to do is get this foot flat because your foot doesn't just hang out on the 00:02:26.190 --> 00:02:27.170 heel here. 00:02:27.420 --> 00:02:30.900 So when we're going you know you're just sliding on the heel. 00:02:30.900 --> 00:02:32.470 That's not realistic. 00:02:32.500 --> 00:02:34.740 Need to get this foot roll down to zero. 00:02:34.870 --> 00:02:36.090 So let's get that to zero. 00:02:36.210 --> 00:02:42.990 And then you can see that the leg is very straight and that can help us guide us to kind of know biomechanically 00:02:43.470 --> 00:02:49.800 how far down with this yogini to go to keep that knee from popping and getting too straight because 00:02:49.800 --> 00:02:55.080 if we were up here with the center of gravity then the leg would be far too straight and it would be 00:02:55.170 --> 00:02:58.120 a pop right when the foot goes flat. 00:02:58.170 --> 00:03:05.130 The knee would be very hyper extended to the point they would pop right here so we can use the fact 00:03:05.420 --> 00:03:08.700 that we know the foot needs to be on the ground to drag. 00:03:08.700 --> 00:03:15.710 I'm just shift middle mouse dragging this keyframe down to a point where the knee is no longer you know 00:03:15.780 --> 00:03:19.350 stretch beyond where it would be hyper extended. 00:03:19.600 --> 00:03:20.260 OK. 00:03:20.580 --> 00:03:31.230 So now when we play this back the knees shouldn't pop and this plane back a little fast but we can scrub 00:03:31.230 --> 00:03:37.950 this we can see it's kind of getting hyperextended here and we can fix that by let's go into the center 00:03:37.950 --> 00:03:46.830 of gravity and instead of having an auto tangent where it will slowly go down we probably need to make 00:03:46.830 --> 00:03:53.340 this to be straight or straight down so we can grab these tangents and middle mouse drag them. 00:03:53.490 --> 00:03:59.060 So they're going straight in an easier way to see this would be to go to view infinity. 00:03:59.490 --> 00:04:07.440 And now I can see that you know this curve is flatlining here so we can actually say curves post infinity 00:04:07.440 --> 00:04:16.410 cycle so that we can see how these now two key frames relate to each other in a cycle which is how we'll 00:04:16.410 --> 00:04:17.020 be using them. 00:04:17.020 --> 00:04:24.180 So it's good to go ahead and see that now so we can see that that kind of tangent continues nicely down 00:04:24.180 --> 00:04:25.320 to the bottom here. 00:04:25.590 --> 00:04:28.730 So that should help us a little bit to keep the knee from popping. 00:04:28.730 --> 00:04:34.030 It looks like it's still popping a little bit and that could maybe be from the foot. 00:04:34.380 --> 00:04:38.530 Look at the foot and the translate Z. 00:04:38.880 --> 00:04:46.100 Now any time that we are animating and we're moving at a consistent rate with our feet right. 00:04:46.240 --> 00:04:54.930 You have to think about this is a special way to animate that we're animating on the spot meaning he's 00:04:55.020 --> 00:04:56.010 staying on the same. 00:04:56.010 --> 00:04:57.880 He or she is staying in the same spot. 00:04:58.380 --> 00:05:02.320 And in reality there are going to be moving across a distance and if they are moving across a distance 00:05:02.320 --> 00:05:07.000 and this foot is going to stay in its place then these need to be linear. 00:05:07.000 --> 00:05:12.610 They don't need to be you know nice smooth tangents to go ahead and delete that. 00:05:12.640 --> 00:05:19.930 I'm going to select all of these and go to a linear motion here because as soon as this hits the ground 00:05:19.930 --> 00:05:21.390 it should be moving. 00:05:21.970 --> 00:05:29.020 And in reality we might want to move this foot roll zero back a couple of frames. 00:05:29.350 --> 00:05:36.580 So now it's coming down much sooner and it's working a lot nicer. 00:05:38.370 --> 00:05:45.580 So as this foot comes down we can see now that it's catching the weight of the center of gravity. 00:05:45.930 --> 00:05:51.960 And only after that this is flat and it's catching the weight can the center of gravity go up because 00:05:51.960 --> 00:05:57.030 it needs the center of gravity is pushed up by something that just can't float around willy nilly. 00:05:57.030 --> 00:06:02.130 We do understand the motivation and the biomechanics of a walk one is actually keeping the center of 00:06:02.130 --> 00:06:03.490 gravity from falling over. 00:06:03.570 --> 00:06:04.950 Well it's these feet. 00:06:04.950 --> 00:06:05.610 All right. 00:06:05.640 --> 00:06:12.940 And so these keep it upright so we can see that only after that this takes the weight of the center 00:06:12.940 --> 00:06:13.730 of gravity. 00:06:13.740 --> 00:06:15.400 Can this go back up. 00:06:15.730 --> 00:06:16.060 OK. 00:06:16.080 --> 00:06:17.270 So we wait for that to happen. 00:06:17.300 --> 00:06:19.840 And then this goes back up. 00:06:19.860 --> 00:06:20.420 Right. 00:06:20.640 --> 00:06:22.320 And that makes sense. 00:06:22.320 --> 00:06:32.160 So now we get into this pose cool and we can go ahead and make these be linear on translate Z on the 00:06:32.160 --> 00:06:34.890 other foot as well because we know that's how we're going to be working. 00:06:39.720 --> 00:06:42.480 So let's bring this back out to 40. 00:06:42.620 --> 00:06:48.210 Just take a look at this one breakdown real quick and see how much that little bit of animation added 00:06:48.690 --> 00:06:55.440 We can see the difference between this this foot and this other one you can see all this other one kind 00:06:55.440 --> 00:07:00.750 of floats and the foot roll doesn't cut to the ground with the other one the foot Ragatz the ground 00:07:00.750 --> 00:07:01.470 pretty well. 00:07:05.840 --> 00:07:16.790 Go So it looks like we could probably you know adjust the Y translate now that we have the feet in linear 00:07:16.880 --> 00:07:22.300 space member only grab these and now the translate Z is linear. 00:07:22.310 --> 00:07:28.070 Now it's also affecting the distance of the you know why translate translates so we could even take 00:07:28.070 --> 00:07:37.330 this let's grab the two top ones and let's experiment a little bit and drag these up. 00:07:37.670 --> 00:07:46.100 Looks like it won't be enough so maybe we can even bring this up or you mess with the tangent a little 00:07:46.100 --> 00:07:47.620 bit. 00:07:47.810 --> 00:07:54.850 So we'll see if that helps keep this leg straight because we don't we don't walk bit in need. 00:07:55.230 --> 00:08:10.880 So as you do this you might find what you have been animating isn't exactly what you need. 00:08:11.010 --> 00:08:17.310 So the other thing to think about is that there's going to be a little motion forward and back as as 00:08:17.310 --> 00:08:24.120 você se move para a direita você vai ganhar velocidade e perder velocidade como você está indo empurrar para cima pelo seu pé para cada 00:08:24.120 --> 00:08:28.970 empurrar o pé vai empurrar o seu centro de gravidade para a frente um pouco. 00:08:29.160 --> 00:08:34.560 Então você pode realmente empurrar o centro de gravidade para frente e então ele pode cair para trás 00:08:34.560 --> 00:08:37.000 isso entre. 00:08:37.010 --> 00:08:40.920 Então, isso é outra pequena coisa para pensar sobre como este movimento realmente funciona 00:08:49.910 --> 00:08:51.750 então vamos fazer isso também. 00:08:51.910 --> 00:08:57.940 Quando isso atinge o chão, sabemos que o pé rola, você sabe, talvez dois quadros à frente, eu acredito que é o que 00:08:57.940 --> 00:09:00.630 nós fizemos no outro que vai ser zero. 00:09:00.670 --> 00:09:09.350 Isso vai ser um pouco e nós vamos fazer alguns quadros mais tarde 00:09:09.490 --> 00:09:14.800 o centro de gravidade executa um movimento para mais dois quadros. 00:09:15.020 --> 00:09:15.680 Jogue de volta 00:09:19.630 --> 00:09:23.260 pode ser um pouco mais que você pode ver isso meio que indo e voltando. 00:09:23.310 --> 00:09:28.380 Então nós temos que traduzir Z e então podemos simplesmente arrastá-los para baixo e também podemos ver onde você sabe disso 00:09:28.380 --> 00:09:29.120 entre. 00:09:29.130 --> 00:09:31.930 Nós não nos sentamos para traduzir Z. 00:09:32.010 --> 00:09:36.980 Então, enquanto aqui nós temos isso, você sabe estar no zero. 00:09:37.050 --> 00:09:41.720 E esse não foi o caso mais cedo, então vai saltar um pouco mais aqui. 00:09:41.850 --> 00:09:45.650 Então vamos apenas arrastar esses valores um pouco para baixo, não queremos ficar muito loucos com isso. 00:09:45.660 --> 00:09:50.970 Mas em geral você sabe que não entendemos a ideia de como o centro de gravidade está se movendo 00:09:50.970 --> 00:09:52.540 do jeito que é. 00:09:52.540 --> 00:09:54.940 Vai se mover muito sutilmente para a frente. 00:09:54.960 --> 00:10:01.320 Então, a próxima lição, vamos dar uma olhada nestes joelheiras e terminar de conhecer esses outros 00:10:01.320 --> 00:10:02.540 passando posições certas. 00:10:02.550 --> 00:10:05.750 Bem aqui o joelho está começando a se curvar muito cedo. 00:10:06.030 --> 00:10:11.880 Então, vamos continuar limpando isso e a próxima lição e então passaremos a adicionar a parte superior do corpo. 00:10:11.880 --> 00:10:12.560 Obrigado por assistir.
