 Okay, this is part two in the tutorial on very basic, most in tracking in Blender. I'm using Blender 2.63 and just to start off, make sure your dimensions over here match your video. So frame rate and the resolution. If you set that to your video that you're importing, it's gonna make things a little bit easier later on down the road. So just do that. We got our default scene here. I'm gonna do real quick, I'm gonna delete this cube because we're not gonna need it. Zero on there, sorry, one on the number pad. We'll move to front view, control alt zero on the number pad, should move the camera to that view. And in this particular case, I'm not gonna be using the lighting, so I'll just delete that to get it out of the way. But that may vary on your project, whether you're gonna use that lighting or not. Next, I'm just gonna change this view to a movie clip editor. I'm going to open a clip. I'm gonna go to where I have some clips saved, switch this to icon view and scroll way down because way down towards the bottom, there should be a video of me here. Open that. And if we shuffle through this, you can see that it's just me with a piece of paper and I drew four little markers on the piece of paper and those are the markers we're gonna track. The fault project's 250 frames a second, or 250 frames total. I'm gonna cut this off. It looks like 350 frames would probably be good. So I'll set my project to 350 frames, shift left arrow or bring us back to the first frame. I'll scroll in here and once again, this is the second tutorial. I hope that you watch the first tutorial because this next part is basically what we did in the first tutorial. So I'm gonna go through it kind of fast, but we're gonna set some markers. I'm gonna scale them up using S, G to grab and move them and I'm gonna set four of them. Now we can track them individually, just like in the first tutorial we just tracked one. What I'm gonna do once I have all four of these set in place, I'm gonna hit A twice or however many times you need to select everything. First time you hit A we'll probably deselect everything, hit a second time we'll select everything. And at this point I'm gonna try to track all four, although I'm pretty sure we're probably gonna lose at least two of them at some point, maybe three. I already lost that first one at the bottom left there. It's no problem, we'll go back and track the rest of it later on. Lost the second one there and that's where I thought that I would probably lose some, but we still have two of them, so luckily we only have two to go back and retract. So selecting this one, scrolling back here, right here is where we lost it. You can use your arrow keys left and right to find that last little frame, G to grab it and just reposition it slightly and press this play button again. Should start tracking it again, lost again. That's basically because when I turn the paper towards the camera like that, our circles kind of become elliptical shape and so they're no longer circles. So if the tracker loses them, and when we came out of it we lost again. So we will reposition that and I think we'll be good on that one till the end. Oh no, we're not, we lost it again. Still much better than doing each one of these frames by hand. Okay, now we're gonna go back and find where that one lost tracking, which was pretty much right off the bat. Yeah, right there. So right here I'm going to grab, just reposition it and press play. We will probably lose it again when I turn the paper towards the camera right here. Okay, so just grab it, reposition it and press play. Probably lose it again when we come out here. And hopefully we'll be good till the end once all the way to frame 350. And if so, good, okay. So once again, just like in the last tutorial we're gonna split this view, set it to a 3D view, which is our view here. I'm gonna hit T to remove that tab or that panel on the left there. Remember where the cursor has to be over this frame when you hit T to remove that. And basically I'm gonna hover over here, hit A till all these are selected. Tab to go into edit mode on our little trackers here. And now I'm gonna say link empty to tracker or to track. Click that and we've got four empties. We can also at this point set the background, set as background, so we move that image over here. And we will join these two windows. And if I hit Alt A now in here you can see that our empties are following our little dots that we were tracking pretty perfectly. Okay, escape to get out of the animation there. Shift left arrow to go back to the first frame. At this point we're gonna import, I'm gonna import still image but you could do a video, whatever you'd like into a flat plane. So I'm gonna hit space bar, I'm gonna type in plane. And once again I'm gonna use the add-on which is called import images as plane, built in by default, not enabled by default. It's under user preferences add-ons. If you don't know how to do that, once again you need to go back and learn the basics of Blender. So I'm gonna do that. I'm gonna just find an image here. Find image, hop out. This great one of my wife right here. We'll do this one here. I'm gonna say huge shadeless, alpha's not important, pre-multiply. Once again these options, normally you probably wouldn't do shadeless because you'd want to match the lighting of your original video. I'm not worried about that in this case. I'm gonna hit RX 90 to rotate it 90 degrees. Now at this point, it's very important. One, what we're gonna be doing is hooking each one of these vertices to each one of these empties. But it's also very important that they're lined up perfectly because if you try to eyeball it, which I tried when I first started doing this, it's gonna not look right. So what we're going to do is I'm gonna select one of these empties, shift select our plane tab, select the versi I want, oh, I skipped a step, sorry. Get out of edit mode, select the empty. And then we're gonna say shift S and we're going to move our cursor to selected. So now our 3D cursor is right centered on that empty. There might be an easier way to do this. This is how I figured out how to do this. I kind of made this up myself here. So after the cursor is centered on the empty, select the empty, shift select the plane tab, select the versi, and then shift S and we're gonna say our selection to the cursor. Now it's lined up perfectly. And now we're gonna link that versi to the empty so that it follows it. So at this point we're gonna hit control H and we're gonna say hook to selected object. So tab to get out of edit mode and if I press alt A to play now, you can see that that versi is tracking that empty. Perfect, we just have to do that little process. In this case, four more times. Escape, so select this empty, shift S, cursor to selected, then shift select, tab, select this versi, control H, hook to object. Oh no, I'm sorry, yeah, that I don't think matters what order we'll do. Shift S again, selected to cursor. Okay, so it doesn't matter what order you do those two things. So now select this empty, shift S, cursor to selected, shift select, tab, select this versi, shift S, selection to cursor, control H, and hook object to selected. Now I will show you something that I do by accident all the time when I'm doing this. So select that, shift S, cursor to selected, shift select this, tab, select this, and now there have been times where selection to cursor, instead of hitting control H to hook it, I hit shift H, which hides that object. Just hit control Z to undo that. If you hit shift H instead of control H and hook to selected object. Okay, so now we can alt A and you can see the animation. We can put this into textured mode and you can see the picture of my wife is right there. And I mean, besides really touching it up probably mostly in the compositor to match our scene, we're doing good. But once again, just like in the first tutorial, if we hit F12 to render, you get that image, but you don't get the background because we need to go into the compositor now. We're gonna go compositing, use nodes, automatic render. We're going to render our 3D view here. Shift A, another input would be movie clip. And don't click open, click the little film strip here because we've already imported the video. Boom, there it is. And then we'll go shift A, shift A, color. And once again, depending on how you're gonna mix this, you might wanna go to mix. In this case, I'm just gonna do an alpha over. So select that and what we're gonna do is the background image to the top yellow, the 3D render to the bottom yellow and then the alpha to this frack input. Connect that to the render there. And if we scroll out, you can see it there. So now we just need to save it as a video or render it as a video. So we'll say, I like using Xvid. I'm gonna do Xvid and code preset Xvid. And I will just save it as track tracking 2.avi. I will click animate. It will create that avi for me, which I will play here in a moment. And I just like to ask you to visit my site, filmsbychris.com, that's chris.k. Should be a link in the description. Hope you enjoyed this tutorial. There'll be one before it. There'll be others coming in the series soon. So check out the description for details and all that. If you have any questions, feel free to visit my website and click on the help, which will bring you to our IRC channel, which is pound filmsbychris on the free node server. Much better chance of getting your questions answered if you go to the IRC channel rather than putting it in the comments on the YouTube video, because good chance they won't get answered there.
