1. Introduction: Hi everybody and welcome to the next chapter. And this chapter we are finally going to start with a little bit of animation. We're going to learn about frames, levels, onion skinning. And we're also going to learn how to export the animations. In this chapter, we're still keeping it quite basic. But in the next chapter we're going to start learning some more advanced topics like tweening. This is actually the second chapter of this course. And it assumes that you already know the basics about vector drawing in open tunes. So if you already know about vector drawing, then jump on in. And if not, then I recommend that you have a look at the first chapter first. So let get started. See you in the first lesson. 2. Explained: Basic Animation: So I hope you got some practice using the basic drawing tools by drawing the frog and the fly. In this video, we're finally going to start learning about animating something. Remember in this period lessons, you don't need to do anything. This is the passive learning stage. So just sit back and relax and let them knowledge and to your brain. So first of all, let's go to our acts sheet, which is, if you remember, our vertical timeline. So anyway, currently we have only one frame. So let's click and drag to make it a bit longer. Now we have six frames, but we still have only one drawing. That's because the same drawing populates each and every one of these frames. Or in other words, each and every one of these params is identical. Having the exact same prime all the time is not exactly what you call an animation. So what we're gonna do is we're going to add a new prim. I'm gonna click the fourth frame. And I'm going to right-click and I'm going to choose duplicate. So now we have two drawings growing number one, which occupies the first three grams, and drawing number two, which occupies params 46. The drawings are still identical, but at least we have to reframes now. So I'm going to modify the second drawing using the control point editor. So now when I click on preview, we see that there is a small change. So let's make this Tunes level a bit longer still. We're going to drag it all the way down to 24 frames and add a new drawing over here on frame seven. And let's repeat the whole process to make a fourth, fifth growing in frames. 10131. Thing we can do to make our life as animators just a little bit easier is what's called onion skinning. When you onion skin, you super impose previous frames onto the frame which are currently editing. Superimposed just means you're projecting. So in other words, you're projecting previous frames onto the current frame. Let's do that by clicking in the middle of this column above this red and green circle. So as you can see, I've just added an onion skin reframes before the current frame. And now I've added an L1 pre-prints before that. And as you can see, this red line appears. This red line shows what the drawing looked like on frame seven. We don't see what the drug look like in frame ten because that frame is actually for now identical to the currently selected frame. So let's change that and let's make this nine creep on a little further. And as you can see, it reveals a darker red line. So as you can see, we've got the current drying, which is in the active colors. We've got a dark red drawing. This is what was in the first onion skin. And then we've got a light red drying debts in the onion skin further back. So let's continue drawing this worm or the squiggle or whatever it is until it reaches the edge of the canvas. So let's look at the preview law. It's actually looking like something that's animated. So by the way, onion skinning isn't only for showing past frames, but you can also show a future frames. Future frames show up in green. And you can also choose to shop frames which don't depend on where the red and green circle is at the moment. To do that, just click on the left side of this column. For example, I want to show the first and the last frame. And these show up irrespective of whichever is the current frame I have selected. And that in a period Cornell. Now we are ready to move on with our practice. So see you in the next video. Bye-bye. 3. Step-by-Step: Frog Eats Fly: Okay everybody, welcome back. In this video, we are going to complete our basic animation. Let's start by shrinking this fly because he's quite big. I mean, look at that. He's as big as frog's head. If the frog would eat him, his whole head head would explode. Anyway. This serious that shrink the size of this fly. And let's use the selection tool to do that. Again. So something like this is good enough. And now we're gonna do what's called frame-by-frame animation. That means we just gone to handle each frame one by one from the start to the finish. First we take this frog level and we extend it. I guess we'll be using 24 frames. So let's drag it down here to 24. I can always adjust this later if I have to. And I'm gonna do the same for the mouth. Next, let's go back to the fly level. Select the entire fly and press control C to copy. Go to the next frame and press Ctrl V to paste. For now you can see we have two drawings in two frames, and then let's add four onion skins. And now in the second frame, i'm going to use a selection tool again and I'm going to move the drawing just a little bit. And I'm going to repeat this many times. So let me just paste in all the frames. I'm going to use Control-C, Control-V, Control-V until we get to about here. And it's a here that the fly will get eaten by the frog. And now it's time to move each and every one of these drawings. Is this the best way to do this? Absolutely not. No, much better ways. But because this is a beginners tutorial, we're gonna do it the most straight forward yet one of the most tedious waste in a future video, we're going to learn a much better way to do this. There is one advantage to this way though, and that's as beginners, we're starting to get a feel for timing. And when the fly reaches here, he will reach his final destination. So we can preview what it's gonna look like over here. As you can see, it's a bit on the fast side. So one way I can slopping down is by decreasing the frame rate. Next, we also want to animate the mouth of the frog. Let's add a new drawing over here. So we right-click on the level over here and choose duplicate drawing. We have a number two over here. So we can modify this drawing. And in order to open this frog's mouth, I'm gonna use this funny pumped to the pump TO simply widens the stroke. Click and drag on the stroke width the pump tool to make it more wide or more narrow. Duplicate the drawing again, and widen the mouth a little bit more. And again and again. And we also want to draw a tongue. To do that, we need to add a new style impact. I realized I made a bit of a mistake. A mistake is also a learning opportunity. What I did is I started opening this map a little too late. So if you do something like that and the timing is off, in that case, no worries, you can move these frames. And most straightforward way to do that is to copy and paste these drawings. Let's make them mile per bit bigger still. And finally, let's start drawing in the tongue. We are also going to animate the tongue in a frame-by-frame way. So now we've done animating the mouth as it opening. And next we have to animate the mouth has its closed. Luckily for us, closing mouth is just exactly the same as an opening map only in reverse. So all I'm gonna do is I'm just going to copy and paste these frames, but then in reverse order. And now we're almost, almost done. The last thing we need to do is make sure that this fly, after it gets caught by the sticky, it should get pulled into the mouth. Together with the time frames we need, the flight, follow the movement of the tongue. And so follow along with the steps if you haven't already. In the next video, I'm gonna talk about the assignment for this chapter. So you soon, bye-bye. 4. Challenge: Arrow Pierces Heart: Hi everybody and welcome to the first independent exercise. In this exercise, the goal is to create this simple animation of an Arab piercing heart. Remember, it's best to try this exercise first without looking at the solution. Do your best. But if it gets dark and you feel you're getting frustrated, then it's absolutely fine to have a look at the solution to unstick yourself. Some of these exercises can get quite challenging. And it's perfectly normal not to be able to do the whole exercise by yourself. The most important thing is that you are actively thinking about the solution because that's the fastest way to learn. And as long as you give it your best shot, you certainly learned a lot. And that's what this is all about. After completing the exercise, why not have a look at the solution that I made even if you did not get stuck and the exercise was quite easy for you. It can still be interesting and fun to examine the different ways in which you and I approached the problem. So let's get started with the solution. Pause the video here. And here comes a solution. First, create a new tunes vector level. Then use a polyline to draw the heart. It's better to use are just a few control nodes. So in the case of drawing a shape like a heart, than six control nodes are definitely more than enough. Next, we use a line to draw this arrow. Whoops, I should have actually drawn this line on another level. No problem. I can just copy and paste it. Okay, let's add another level for the bow. And let's add a brown style for the color of the wood of the bow. And I think for the bow, just a simple line is enough. Okay, now we have a bunch of static images. Let's get two animating them. First we dragged down this heart level. And then let's duplicate all these arrow frames. And both frames, you can press D as a keyboard shortcut. Okay, to start animating, the first thing we do is move this arrow back slowly. Then we want to adjust the control points for the bow and the string of the bow. This can be a little bit tricky and a little bit fiddly, because we also have to adjust the direction handles as well as the control points themselves. Frame by frame animation can really take long time. So you have to be a little bit patient when doing frame-by-frame animation. In fact, there's much faster ways to do this, but for now it's pretty good practice when it comes to working with levels and also when it comes to getting a feel for the timing of this frames. That said, in the next chapter we're going to learn about in between ink. So definitely have a look at the next chapter to learn about that, to save a lot of time. Ok, now that we've pulled the arrow back, we want to hold it stationary for a couple of frames. And then after that, the Boas spring back to its original shape. So for it to suddenly spring back, let's copy drawing number one down here. In fact, I'm going to convert a string to a single line rather than two. And I'm going to animate to reframes where the string continues to five Brit even after the arrow has left the bow. And of course we want the error to fly off quite quickly. So let's use the Selection tool to move it. And when the arrow reaches the hot, we use the eraser to make it appear as though the front of the arrow has pierced it. And in the last couple of frames, the arrows slows down as it enters the heart. As we run preview, we see that I've made one small mistake. We need to remove this excess frames. And there we have it. Thanks for watching. In the next video, I will have a creative assignment for you. So see you in the next video. Bye-bye. 5. Appendix A - Exporting: So I guess he did a good job following the step-by-step instructions and doing your own creative assignment. Next, we're going to learn about rendering. Normally I would leave rendering until much later stage. But if you want to be able to upload your assignment, you're going to need to learn a bit about rendering first, you can easily rendering open tunes by going to the menu item render and then clicking on render, it will create a preview like this one. Currently the animation is rendered as a series of pictures, which we can find in the output file. You can modify the render settings by clicking on Render and then output settings. For example, I can modify the export folder, and I can also modify the file type. Right now, I only have the option to choose stationary pictures. So as you can see when I go to the output folder, I see a list of pictures flipping through these pictures shows that the animation actually works. But probably you don't really want a list of pictures, but you want a video file or an animated GIF file. So what I usually do is I convert these series of pictures into a video file using FFmpeg. Ffmpeg is free and open source, and it's not that hard to figure out how to use it using the command line. However, if you couldn't really be bothered to figure out how to use FFmpeg. There are various other options. Most video editors offer the option of converting pictures into videos. And it's also possible to integrate FFmpeg so that open tombs were handled all the settings and stuff like that. And that way you don't really need to worry about learning how to use the FFmpeg command line. But first we're gonna talk about why that background suddenly became black. Because even though it looks wide on open tombs, actually it's transparent. Front video players display transparency in different ways and mind is plotted as black. So what we want to do is we want to change the background from transparent to White. To do that, just go to x sheet and then scene settings, and then change the value for a from 0 to the maximum value of two 55. A stands for alpha by the way, which is just another way of saying transparency. As you can see now, the pictures have exported with a white background instead of a transparent background. So next let's talk about integrating FFM page into open tombs. I will demonstrate this for Windows because I'm assuming most of you will be on a Windows. But if you're on Mac, it can be done in more or less the same way. You can find instructions for this on the. Open tunes documentation page, specifically on this website, you can type over this link or you can just search for using FFM peg with open terms. Down here we can find instructions for Linux, for Windows, and for Mac. First we need to download FFM peg. Let's get the one for Windows. In theory, you can pick either of these, but I'm gonna pick this one be TBN. Honestly, I'm not sure what the difference is between all these versions. So I'm just gonna pick Windows 64 GPR. I'm gonna download it and I'm going to copy it to a folder on my drive. Then I'm going to put for one specific file in the bin folder, you should find FFM peg dot EXE. That's an important file. That's the one we want. So I'm going to extract it. And I'm going to just delete this zip file because I don't need it anymore. And I'm gonna copy this folder. Then go back to open tunes, file, preferences, import and export. And over here you can set the FFM peg path. That's where you paste the path which we just got. Then the final step is to restart open tombs. And let's just make a very quick test animation. Then I go to Output Settings and I want to turn to a type of file to give. And let's just put it on the desktop. Here it is. Let's see if it works. It works. So that's an easy way to export into animated files. So take your assignment and export it to a gear for mpeg or whatever you like and uploaded to get some feedback. Looking forward to seeing your assignment. See you in the next chapter. Bye-bye. 6. Appendix B - How to get the most out of this Course: In this video, I will give you a quick explanation on how each lesson is structured and some quick advice on how I would recommend you get the most out of this course. Each chapter contains three types of lesson. The first type is a theory lesson or of overview lesson. And the goal of this type of lesson is just to get you familiarized or acquainted with the basic concepts. It is type of lesson. There's not that much expected from you except just to watch the lesson. A lot of people like to take notes. So if it helps you concentrate by all means, do a lot of people like to follow along with the theory? You cannot, if you like, but it's really not necessary. The main point is just to get a rough idea about how everything works. So this lesson is quite passive. So the next type of lesson is a bit more active, and this is what I call the follow along exercise or the walkthrough exercise. In this type of video, I provide simple step-by-step instructions, follow along with these instructions. And together we will be creating some animations. This will be the first hands on experience that you get in this topic. And the third type of video lesson is that practice, exercise are the do it yourself exercise each DAY exercise, practice exercise comes with a solution. With the DIY exercise, it might be a little bit tempting to have a look at the solution before even starting the exercise yourself. I mean, it's not like I'm your Mother. After all, I'm not going to check you and I know you probably have a lot to do and stuff. But to get the most out of this course, I highly recommend that you try the DIY exercise yourself before looking at the solution. Doing the DIY exercise yourself as many advantages. First of all, you practice and you think this is what we call active learning as opposed to passive learning. Second advantage is that doing these exercises yourself will help you develop your own style. For example, perhaps you will find a solution which is much better than the solution that I found. Or perhaps you will find a solution which is not either worse or better, but just Fritz, You better fits your own attitude or frame of mind better. There is one disadvantage though to the DRY exercises. And that's you might tonight and not succeed. And that might actually discouraged you. So at my advice is, don't get discouraged. It's not a test after all, so it really doesn't matter if you pass or fail. It's all about how much you learned. Some of these exercises are quite difficult. So if you don't succeed in all of them, that's not at all a surprise. The main thing is that you're actively thinking about this and in that way you're learning. It's actually by experimenting and making mistakes and feeling confused and uncomfortable that you learn the most. That said, don't spend too much time on the independent exercises. If you get stuck and you keep trying to chisel away at this problem, that's not an effective use of time. So the trick is to find the right balance. On the one hand, you want to be persistent enough to challenge yourself. On the other hand, you don't want to become obsessed with the problem and waste a lot of time getting bogged down in details. Once you have completed an exercise, it's usually a good idea to upload it so you can get feedback from another person's perspective. It's also a good idea to create a project of your own without any guidance from me. If you do, feel free to upload it here too, so I can give some feedback. So I hope this video was helpful. I will see you in the next video. Bye-bye.
