Ah, finally figured out a good place to host it. This is a test a friend and I did together for our video final to see if we could implement a 3D computer-generated background into footage. This is why I started using Blender in the first place.
You can see a lot of information here, but don’t watch it in that window, as it’s cropped… Underneath the square window which starts out black, there is a direct link to the movie, watch it there. It’s in .mov format so Quicktime (the latest version) or an alternative is necessary. The file is about 9 megabytes.
Some of the green-screen keying is bad, but I did it on a dark monitor where it didn’t show up. I also didn’t have time to carefully matte out all the little messy blotches. I still think it turned out fairly well. I wouldn’t normally call it finished but this is what we turned in. Feel free to make suggestions or comments, as we plan to redo it (not completely redo the background but make modifications and reshoot the footage).
edit: I forgot to mention, I was nervous when we were shooting it because we were running out of time, and I’m not steady to begin with, so the footage is very shakey. Sorry, and try to ignore it I guess?
WIP thread has more background on the project if you’re interested. Please discuss here from this point.
Only thing that bothered me was the shaking camera.
Again I apologize for my own shakiness.
Since the camera was shaky, how did you keep the 3d background steady with the scene, what program did you use?
As redbyte said, I used Icarus, a camera motion tracking program. I taped crosses onto the green screen and Icarus tracked them and calculated the camera motion. It’s very accurate, I’ve been quite impressed with it.
I ment to comment, but Mozilla kept crashing when I tried (not kidding). One thing tho, at then end, it seemed like she was looking at a wall, and not down a street/road. Otherwise, very nice
Ah, but it fits, doesn’t it? I feel it fits perfectly. It has exactly the feel I wanted. It took forever to find, too. Went through several hundred songs (just the intros to most of them).

Well, she was staring at a green screen in reality. I thought she did all right, not having any idea how it was going to be laid out behind her. We also rushed this take, this was the last one.
Can you upload it with a different file format? I tried in IE and firefox but quicktime is being stupid. I want to see it though.
Do you have the latest Quicktime? It won’t show up in any other version (I tried). If you do and it doesn’t work, is a DivX AVI all right? It’s the only AVI codec that I have that I can get the file to a reasonable size with. The sound’s a little scratchy and there’s the DivX logo in the corner but it’s only 4.4 megs. You have to download the codec, but at least it’s easy to find. I’m not sure whether the other ones I have are standard.
That goes for anyone else who can’t see it for whatever reason, is DivX all right?
edit: Also, if it won’t play in your browser, try right clicking on the link to the file and choosing “Save as” or “Save link” or whatever your browser does.
Ah… thast the problem- the desk looked like the floor, making it seem well… odd. So now that thats resolved, nothing wrong wiht it that i can spot, becides the flicker around the person(I know, that can be VERY hard to get rid of, having worked with a greenscreen my self)
A+ work

It wasn’t the green so much as the tracking crosses that was a problem (that’s not to say the green is perfect). We used blue tape for the crosses because logically we could key out the blue too, right? Except that our screen is the LED reflective kind, and the green LED ring turns the blue crosses to gray, which we can’t key out so well.
edit: Here’s what the footage originally looked like, just for everyone’s amusement.
I think you’ve done well with the tracking. There is some aliasing on the buildings though. Blender is quite bad for that. As well as the standard OSA, try turning on the full OSA button for your building materials. If the render times are too long, you might get away with reducing OSA. Also experiment with the new sampling filters.
i wouldnt say render quality was an issue, however when the camera moves it appears to have very little depth to the buildings, but i guess thats the nature of the beast…
