Voiceover: Hey, everybody. Welcome to 3dmotive.com Tips and Tricks Videos. I’m [Craddock], your instructor, and today we’ll learn a cool trick on how to use reference for animation. Every animator uses reference while animating. It’s really good to come up with a workflow that suits the best for you. This trick that I’m going to tell you about is already used by industry veterans and professional animators because it really helps in understanding the use of reference. Using reference for understanding is different than using reference frame by frame which itself has a term called rotomation. Today we’ll discuss a way how to break down reference and learn to take important parts of the reference to help push the idea of the animation. All right. Let’s begin. You have got a character and I’m going to pose him for animation, but in this video we’re mostly going to learn about extracting the pose or the idea from the reference. Before we go any further with the tools, let’s discuss a bit about the reference. There are a number of ways to set up references. Let’s play it in QuickTime there. All right. Here we go. There’s a run cycle with a guy. What I need is all these poses, right? What I’m going to do is I can either try to understand this pose here, and then try to match it up here. Or what I can do is I can bring the video itself here in my app so that I don’t have to keep on watching this video over. I’m minimizing and then working here and then opening up again. Let’s go ahead and create a plane here. Since we need a image sequence here, let’s go ahead and create a new material, lambert. In lambert we need a file texture because we’re going to be putting a file in here like an image file. We’re going to go to image name and I have already converted the video into jpeg images. I’m going to press Open and I’m going to use mid-sequence here. This is going to disappear because my number starts from 1 and it’s going to probably start from 33. What I can do is I can frame opposite of this making 33 which means the number 1 is 33 now, 30 frames offset from 1. When I play this now this looks perfectly normal positioned correctly in front of the character so that I don’t have a problem. Right now I need is all the contact poses for this guy. For example, this contact pose here and this up pose, contact, up, contact, up ,contact. So for example, we need this pose here. We have to first understand that how many frames are here in this video. For example, we go to the image so it’s 33, and the last image is 581. For this trick to work, we need to break this expression here. This expression connects consecutive images in an image sequence inside a folder. We can use that function to actually get the important poses from the video. For instance, sometimes while animating it gets really confusing as to which pose to use from the video and what breakdowns to use. Wouldn’t it be awesome if the video itself was playing in step mode so that while animating all we need to do is scrub through the video and get all the poses we want. To clear that out, let me show you how. Let’s go to this image number here. Let’s first of all delete the expression from here. Nothing’s going to be happening here. What I need to do is I need to set a key here and since we have a frame offset of 33 which means our number 1 is actually 33rd frame of this video. We go to the end of this 500 and we put a 533 there and rightfully again set a key. What we have now is the whole video here. Since we have keyed from 1 to 533, we now have a graph for this. We have to find that graph. We know that this video is a image sequence which means it’s an image file which means it’s connected to the shader of this plane. We need to find that shader first. Let’s go to Hypergraph connections, press Frame, F for Frame and then we can go and select this lambert here. When we open our animation graph editor, we can see that we have a curve here. We have a curve here for this video. Whatever we do to this curve, like right now it’s in flattened tangent right now. Even if we change this to a linear tangent, nothing is going to happen here because it’s just a video. But what is going to happen is when we select step mode, it’s not going to work. Nothing is going to work and then in the end it’s going to skip. We can use this function here. Let’s go ahead and select this and change this to linear. What we need are the important poses here. For example, this pose here. Let’s go ahead and select this pose here and go here, right-click and set a key there. We see that there is a key here getting connected. For example, this one we need to right-click and set a key and then we need this one here. Right-click and set a key, and this one here, right-click and set a key. Even though it’s in a straight line, when we put it in step mode, you can actually see that this video is playing in step mode. Let me go through the whole thing. I’ll pause the video and come back when the whole thing is done. All right, now that we are done with the whole video here, we’ve got all the keys here and here. We can select this whole curve here and change it to step mode, step tension. Then we can minimize this. Now what we can do is when we play through this video we’re getting the step mode of the video which makes it more easy for us to animate here. For example, I need this pose here. So this is the second pose. All I need to do is position this guy. Even when there’s a complex acting shot, we will get all the poses in step mode from the video from whatever acting that we have done in the video reference. We can take the important poses from there, put the video in step mode and animate it. It’s a nice little trick. It’ll definitely help animators to get a grab of all the poses that they want. All right then. That was it. Hope you learned this little trick. Thank you for watching 3dmotive.com.
