I finished creating my segmentation boundary.…I have created a couple of base frames, these gold bars and I've propagated that…initial information throughout the link to this clip.…Next I want to refine the matte outline and there is a few ways of going about it.…You might have noticed that this pink outline, the segmentation boundary,…doesn't exactly follow his hair.…You can decide how closely or loosely to follow that hair.…That's the smoothing parameter.…For example, if I was to take smoothing down to 0, you can see now we have got…some crinkles that follow his hair in much more detail, particularly as I go…from frame to frame.…
If I decided I didn't want that much detail, if I want a more feathered outline,…I'll go ahead and increase smoothing to a higher value like 5 and now it just…creates a basic smooth boundary.…If you want to see what that looks like, you can turn off the segmentation…boundary, the alpha boundary, and look at it.…It either gets a checkerboard or against just a black background.…
Chris and Trish Meyer have been using After Effects since version 1.0 and have written ten books about the program, and they are always among the first to dive into each new version and discover what it offers to their fellow motion graphics artists. Chris takes you under the hood and explains how each new feature works in After Effects CS5. This course covers both the technical and creative implications of this latest release, including tutorials on the new Roto Brush tool and mocha version 2, blending modes, text options, and new and improved user interface elements in Adobe After Effects CS5. Numerous examples show the most efficient ways to use the new features and avoid potential pitfalls when applying techniques. Chris ends with a discussion of which users will get them most out of upgrading to After Effects CS5.
