Hello and welcome to this tutorial series on compositing and camera tracking in Blender 2.6!
In this tutorial on compositing and camera tracking in Blender, Greg Zaal of Blender Nerd will take you through the complete process of placing digital, 3D assets into existing footage. This tutorial series will be making use of Blender’s modeling tools, texturing and rendering in Cycles and even using the new Camera Tracker to match the camera movement for a believable VFX integration.
What you’ll learn
In the final part of this series you will learn how to cover up the markers in the footage that were placed as tracking points so that we could track the footage properly, resulting in a clean 3D composite.

Thanks Greg, good to know about this stuff
This is really great to know it can be done.
But this tutorial is the perfect example of what function should optimized during the Mango project.
Maybe by tweaking the ”soon to be” Mask implementation witch could also (by selecting in drop down menu!!?) act as a ”clone mask”. So the first circle of the mask would act as the clone and the second as the fadeout similar to what is done in this tut in Gimp. And IF the Mask selection MUST be converted into a PLANE-(polygon object) well add the option!!
What do you think?

If I had a dollar for every time He said basically…
This was way more complicated than it had to be. I could have done this in five minutes instead of 30.
by all means … please tell us how
Just look at sebastian konig’s blender conference presentation. All you have to do is save a frame of our video and remove the markers in Photoshop or gimp, and then project it onto planes. You an feather it out easily in the compositor.
Quick simplification: The grey circle is from the grey sky being mixed in to the texture. Just turn off sky rendering on that pass, and then premultiply will work fine.
Greg, thanks for the 3 tutorials. I just went through them. I am having problems with the tracking. It’s always off by at least 14. I’ve tried different settings and it only gets worse. Probably my original tracking needs to be redone, right?
Not necessarily, it’s usually just a problem with your camera settings. Just try a whole bunch of different sensor sizes and lens angles. And make sure you have a Camera Solver constraint on your camera!
i wanted to continue to my parts:

part 2: http://cgcookie.com/blender/images/safe-case-movie/
it looked very complicated… sorry i didn’t do the part 3…
When I try key framing the differences in the color of the texture, the texture doesn’t change. I did everything you did (except for that alpha mask thing, because I don’t really need that) but key framing the color levels of the textures doesn’t affect the textures. The texture only changes when I select the different UV Maps in the Object Data Tab. Any tips, if this makes sense?
From what I could tell, it does actually work in the render, but it doesn’t update your viewport.
Yeah, that’s what I mean. I did a little more work and it renders the color change fine, but doesn’t update in the viewport.
Thanks Greg! I always wondered how I was going to remove any tracking markers that I place in the actual recording.
While I was watching your tutorial I started to wonder whether you were South African (Partly of the accent, but also because my home language is Afrikaans and some of your expressions used in the tutorial are from Afrikaans (such as ‘Ag’ as an example)).
Keep up the awesome work you do!
Hope to see another awesome tutorial soon.
Can anyone help me on this?
I’m having trouble matching the render colors with the actual footage. What’s the secret to getting it right on? This was easy since it was a bit green but what about a normal inside scene? I’ve tried drawing out my lights at the time of shooting with the camera but the model always looks fake.
That, sir, is why VFX is an art, and not done by any monkey who knows what buttons to push
It’s tricky – just keep trying to get it right, and take breaks often so that you can come back with fresh eyes. Also it helps to have other people look at it every now and then – they might spot things that you didn’t. Good luck!
