Once done, your subject will show a magenta outline, shown below. What you are really doing is teaching the Roto Brush what portions of the image should also be considered as foreground. The Roto Brush will be able to track any movements the subject might make. To avoid this, click on the 'correct for aspect ratio' button. After analyzing the clip it is presented in its original (non-square) aspect ratio again.

That's why the clip seems distorted during the process. The Rotoscope tool analyzes frame by frame and AE displays the clip in its square pixel equivalent. This is because HDV is an anamorphic format, i.e. The giraffe, shot in HDV, appears to be distorted. The Roto Brush tool does a very good job of recognizing both shape and color information within the subject and motion tracking its movements throughout the clip's duration. No color correction or effects of any kind. My first order of business is to use the Roto Brush tool to mark inside the subject.ДЇrame from the original clip. I can now click on the Roto Brush tool and by holding the command key down can adjust the size of the brush you will be using by simply dragging the mouse either up or down.Дifferent brush strokes for different brush folks. Double clicking on the layer in the timeline will open up its layer panel. The whole process is fairly straight forward. Once I am done importing the clips I can then bring them into the After Effects timeline. I try to make it a habit to make sure that my comp settings are the same as the footage I am importing.ДЇor this tutorial, these are the composition settings I will be using. Initially you create a new composition as you would for any After Effects project. Let's get started and see how this tool will work its magic. Very similar to Photoshop's Quick Selection tool, the Roto Brush in After Effects CS5 will save you an enormous amount of time in post production. Of course, much of the speed can be accredited to Adobe's 64bit Mercury engine, the NVIDIA graphics card and as much RAM as you have available for as many cores as your computer contains, however, the process of rotoscoping your foreground and background subjects is no longer a lifetime endeavor. Prior to the release to the public of Adobe's CS5 suites, I was able to view and review many of the exciting new features now available in most of the Adobe applications, but none excited me more than to see the After Effects Roto Brush in action and to see just how easy and relatively quick it worked. In the past, when rotoscoping any moving object out of its background environment, it took several hours, days or even weeks to mask the subject frame by moving frame just to get a small clip, and then there was even more time spent refining that matte. Heck, once you're in the zone you just can't leave.Д®ven more so, you must have the patience of a bona vide saint to be a Rotoscoper. There is not a one of us who has not said to their companions,' I'm just finishing this up, will be there in 15 minutes tops.', only to find themselves still at work in the editing bay 4 hours later.
