Now comes the strange part: You use this brush to paint a shape that simply suggests the form of the item you want to remove, working inside its boundaries (see Figure1), and the tool attempts to understand on its own where the exact boundaries are (as in Figure2). When the Roto Brush tool becomes available in the toolbar, click it to make it active. Place any clip into a composition and double-click to open it in the Layer viewer. Clarke, Roto Brush is "sufficiently advanced to be indistinguishable from magic." This tool won't magically erase your rotoscoping troubles, but it represents a quantum leap forward in moving image selection, opening up new possibilities that you might not have even considered for working with footage. This feature has caused the greatest excitement (and the most questions) among users of previous versions of After Effects. It's more a question of how and why these add up to a big upgrade, which After Effects CS5 definitely is. Some third-party developers also stepped up, creating valuable additions that ship with CS5, such as major upgrades to Mocha AE and Color Finesse, as well as the addition of the Freeform plug-in from Digieffects.Ĭhoosing the top five features this time around wasn't so difficult, since the After Effects team focused on a few big new features instead of many smaller ones. While trying to solve the problem of rotoscoping (the tedious process of making a frame-by-frame video selection), a couple of the original team members came up with the revolutionary Roto Brush. Other folks were also hard at work on behalf of the application.
Deciding that we'd be better off with one big thing, Adobe converted the entire After Effects CS4 application pipeline to 64-bit compatibilitya change requiring most of the attention of most of the development team, in order to produce the fully 64-bit native After Effects CS5. Adobe's After Effects team was clearly confronted with a similar dilemma. I wisely chose the latter, and found myself rewarded with a dream gaming systemthe Atari 2800. When I was a little kid, I remember being asked whether I wanted a lot of little things or one big thing for Christmas.
