After I had tracked the footage from my End of the World project I brought it into 3Ds Max, which I have running on Windows XP with Boot Camp. I created a ground plane that matched the footage ground. I applied a matte/shadow material to that plane, so that whatever object I placed on top of it would have shadows that looked like they were actually on the footage ground. Now I was ready to start the destruction, so I started with making a hole in the ground. I placed some debris around and in it, and some dirt around that.

I quickly rendered the scene just to have something to show. There’s only a little bit of color correction added over the whole image in Photoshop, but in the final render I will render the 3D stuff separately so I can color correct that separately. I think it looks kind of cool already :).

The next part is adding the meteor impacts using particle systems. That shouldn’t be that much of a problem, but it just takes time to create(and when I say it shouldn’t be much of a problem it probably is going to be a problem of course).

The next part in my ‘End of the World’ project was 3D tracking (or matchmoving) the shot, which basically means matching the movement made with the camera while filming. This has to be done in order to incorporate computer generated imagery(which in my case will be 3d craters, debris, etcetera). For this I use PFTrack, a program by The Pixel Farm. I’m fairly new to 3D tracking(although I’ve tried I a few times before I’ve never really done anything with it). The program can do a lot of the tracking by itself, but I had to adjust some things. To begin with I had to make a mask to cover myself in the shot, as I wanted to move the movement of the camera, I didn’t want the tracker to pick up my movement. Then I added a few points myself which I thought were good points that stayed visible trough the shot and would help the program determine the camera’s movement.

After that I had to make sure the camera parameters were set correctly, some things about the image I already knew and that helps the program determine the camera motion. For example, I knew the image size, the pixel and image aspect ratio and the frame rate. The focal length can be filled in too, but this caused some problems. First I let the software estimate the focal length and solve the shot, and although it looked good in PFTrack, when I brought in the data in my 3D program I noticed that the focal length was way off, the camera was really zoomed in where in reality it was not at all. So, I went back in PFTrack and adjusted that. As I had no idea how I was actually supposed to do this, I googled it and I found some posts about the canon HV30’s focal length(that is the camera that was used) so I could enter these values in PFTrack. That seemed to work out nice.

You can also see the lines that were used to calculate the image distortion. Now as I said I’m not very familiar with this, so I have no idea if this actually the correct way to do it, but I just let the program calculate the image distortion and it seemed to have worked out.

Right now I’ve imported the data from PFTrack into my 3D program, which is 3Ds Max by Autodesk, and it looks like everything worked out. I’ve started creating a crater and some debris, I will soon start creating the impacts from the meteors crashing into the street. So the next post is going to be about all that 3D stuff, which I think is one of the more exciting parts :). Keep an eye out for that!

PS. I’ve had some problems with my iMac lately, my hard disk drive may be failing. I get an S.M.A.R.T. status failure, which according to what I read on the internet is not a very good thing to happen. I backed up all my important files, including every file of this project, so everything should be fine. In the worst case this projects gets delayed a bit, but I’ll still have the files so I can finish it. I will call Apple about this problem, as I’ve no idea what to do. The error says I have to back up my files and replace the hard drive with a working one. If possible I’d rather not send my iMac to Apple to get it fixed because then it will probably be gone for quite some time and it will also probably cost me quite some money..

As the footage for my ‘End of the World’ project was shot I recorded it onto my computer and imported it into after effects. I hadn’t decided if I wanted to do the 3D stuff first or the teleporting in after effects, but I started playing around and before I knew it I finished the teleporting. As I want it to be a smooth shot I stabilized the entire shot (in 2D in after effects). This turned out pretty well, the only thing is that there’s some random motion blur going on, as the actual camera was moving and caused motion blur, and when the footage is stabilized the motion blur doesn’t go away obviously. However I don’t think this will be a big problem, because in the final result there will be all kinds of stuff going on, meteorites crashing, cracks in the ground and camera shake, so I don’t think it will be really noticeable in the end.

What I did was precompose the footage, and stabilized that. I tracked the footage in the precomp and applied the motion of the footage to my teleport elements, which I added in the precomp. I could have added the teleport elements in the stabilized comp but because the stabilization is not perfect I thought that wouldn’t have looked that good.

On projects like this the layer count can really add up quickly, so it’s important to stay organized. Most of the time I start out pretty organized, naming layers and stuff, but in the end I find myself quickly adding just a few new layers and I don’t think about naming them. This is what my precomp looked like after both the teleport-in and teleport-out where finished:

Now because this might become a kind of big project with a lot of layers I decided to keep it organized, so I renamed a few layers to keep things as consistent as possible. What I also did was to give the layers color that matched their function. Nulls that other layers are parented to are fuchsia, nulls with controllers on them are red, lighting effects are orange, etcetera. I also changed the layer order, I couldn’t change the order of the actual elements, but I could change the order of the nulls, and that also made things a bit clearer. You might also notice that I’ve broken the top layer up into 2 layers, this is because of the next step.

It took me a while to figure out which footage I was going to 3D track, the footage before it was stabilized or the actual stabilized footage. I went with the footage before it was stabilized because of the motion blur issue. But that meant that I would have to composite al the 3D stuff in this precomp, so I decided to make things a bit more organized by precomposing all the teleporting stuff, making a precomp for both the teleport-in elements and the teleport-out elements. This really makes stuff a lot clearer, the only thing you have to be careful about is that everything blends the same as it did before precomposing. Turning on the ‘Collapse Transformations’ switch does this, the layers in the precomp react as if they were actually in the comp itself. (I don’t know if that’s easy to understand, if you have no idea what I’m talking about you may want to check out this page.)

So, that’s about it for the teleporting part, I think it turned out pretty nice. Here’s a little still from where I teleport in for your viewing pleasure 🙂 :

Now this still doesn’t show that much, but I thought I had to show something, right? Basically what you see is parts of me already teleported in, some light, and some light casting on the rest of the scene, but all of that will be much more nicer when you see it in motion. I’ve applied a little color correction, I have no idea if this is going to be the final color correction but it works for now. I’ve also added the letterbox to give it that cinematic 2.35:1 aspect ratio which I really like. So that’s it :).

If you have any questions be sure to do that in the comments. Next up is 3D tracking, expect to see a post about that soon!

The End of the World

The End of the World

What if you would discover that you can teleport? You can’t control it and before you know it you end up in a place you don’t want to be in, like a parallel universe wherein the world is coming to its end! Well, that might be a little too far-fetched, but I’ve got to have some story behind my new project, right?

After seeing all of those ‘End of the world-scenario’ movies, I thought I’d give it a try myself. I was especially inspired by the trailer for the ‘2012‘ movie that’s coming out in a few days(make sure you check out that trailer if you haven’t already!). I also really liked the ‘Jumper‘ way of teleporting, so I wanted to do something like that.

What I’m going to be trying to create is one shot, a little over 10 seconds long. The goal really is to make one epic shot filled with VFX. I teleport in, falling on the ground(I can’t control the teleporting), I start running, trying to avoid meteorites that are crashing into the street. At the end I jump and manage to teleport out.

I like working with some kind of storyboard, so I fired up after effects and quickly made a little storyboard, just to have some sort of reference, and to show my father what I wanted to achieve, as he was going to film the shot.

Remember, this is just for reference, none of this will actually be used in the final shot, I didn’t really pay that much attention to artistic detail in here ;).

I made this storyboard very quickly on saturday, and we filmed it on sunday. We shot a few takes, and I think I have one that’s useable. In the next posts I will keep you up to date on how I’m doing on this project. I think this is a cool project, and I certainly hope I can finish it. There may be some difficulties later on(3D tracking is NOT something I’m very good at to say the least), but I’ll see about that when the time comes. See you next time!
