The new background was a static image (called a digital matte painting) that needed to move around with the camera just like the rest of the image, in order to look as though it had all been shot at the same time. To do this, the original scene needed to be "tracked," a tedious process I won't bother to detail here, but through the use of a motion-tracking program (in this case, a wonderful software package called Mocha), I wound up with camera movement information that I could then apply to the background. That would get me about 85 -90% of the way, and then I would need to analyze and hand-tweak any movements that didn't match-up quite right. If all of this sounds labor intensive and detail-oriented, it really was... but the results were very cool!

I mentioned having had two interesting projects of late & thought I'd share a few details:
The first was a rush-job for a music video featuring a new song from the band Default called "Little Too Late," which was directed by Ryan Little. This involved taking 70 different shots of the band performing on a green-screen set and replacing the background with an imaginary cityscape. The initial step involved removing the green-screen from each shot while making sure the edges around the band members remained nice and clean. This was tough to do in some instances: occasionally one of the guys was standing quite close to the camera and nicely in focus, while another would be directly behind the first, yet much further away... and as a result, very much out of focus. (A very artsy-type of look, but a brutal, headache-inducing choice for the FX compositor to deal with, especially with a compressed timeline of only four days!!!)
The next project was a promotional video for ScatterTunes (you can view the final promo here). This involved creating a number of motion-graphic sequences to give the logo and individual features of this interactive media program a stylish, glossy look and feel. Although there was an enormous amount of work involved, this project was great fun creatively, and allowed me to try out several new techniques in simulating a 3D look using only 2D assets (as in this shot of three different MP3 players).
Each player is made from a high-resolution photo, and then made to look as if it has dimension within the virtual set. (I even added glossy screen reflections that move as the camera pans around the grouping.) I edited this piece and added additional sound FX as well, and am thrilled with how the final promo turned out.

We grew our own pumpkins this year, of both the orange and white varieties. As I was looking over my chosen gourd, the pale hue gave me the idea to cook-up a quick batch of home-made playdough (as mentioned previously on this blog) and sculpt my Jack-O-Lantern this year instead of carving it! (Even the teeth and gums are made of the same stuff.) A quick wash of highly diluted water colors, and a finishing spritz of spray-on cooking oil (for that ultra-slimy look), and my evil goblin/pumpkin was complete!
This gravestone was made a few years ago as a family project, with each of my kids making their own out of styrofoam insulation and using a paper stenciling technique I came up with. You tack down a large sheet of cheap roll paper with spray adhesive onto the styrofoam sheet (already cut into the basic shape of your stone). Then you draw out your design, and carefully cut along the lines with an X-acto knife. Remove the 'negative' space, or the areas around your main design elements (like the skull and lettering in my example) ... basically, anything you want to carve 'in' to the stone's surface. Once that's done, lightly spray a solvent-based chemical (like paint remover) over those uncovered areas and watch the evil concoction eat-away at the foam (like Alien blood)! I spray it on a little at a time to get the right depth -- too much looks wrong, and you can't reverse the process. Then you strip-off the remainder of the paper stencil, and paint the thing, spattering the base color (usually gray) with lighter and darker tones to give the whole thing a speckled, ancient stone feel. It's pretty easy & a lot of fun!
Besides these gruesome delights, I've been busy working on some cool new projects, including fx work on a music video and some very elaborate motion graphics for a large-scale promo video. More later!
