Also, don’t expect the same quality matte results that you would get from shooting your subject against a green screen.ĭepending on your footage, if you have a busy background or the lighting is uneven and dark, the Roto Brush tool has a hard time distinguishing between foreground and background.
HOW TO USE ADOBE AFTER EFFECTS CS5 FULL
A simple change on one frame may affect 10 to 15 frames after it, so it’s best to create short sections of about 15 frames instead of a full footage sequence from the beginning. The only downside is that the Roto Brush is looking at pixels in a sequence, instead of drawing vectors that can easily be edited along the timeline. It affects edge smoothness, feathering, chatter, and even motion blur–which is critical when matting people and objects when they’re moving. The new Refine Matte effect, which is also applied when you use the Roto Brush tool, can be used with any matte layer as a standalone effect. Then use the red brush to identify the background. You start by selecting the foreground object with broad strokes of the green brush, and then reduce the brush size to pick up stray elements such as edge highlights, hair, ears, and so forth. At first glance, it appears similar in function to the old Photoshop Extract plug-in, but it works much differently, since it spans several frames of footage at a time. The most publicized new feature in After Effects CS5 is the Roto Brush tool. With improved color management and the included plug-ins like Synthetic Aperture’s Color Finesse 3 and Apply Color LUT, it’s easy to add these native formats to your production directly from the source. After Effects CS5 can now read native AVC-Intra files from Panasonic’s P2 cards, and raw R3D (RED Cam) footage. AVC-Intra and RED compatibilityĪs the popularity of tapeless HD digital video workflows increases, so do the demands for post-production to accommodate these new formats with a minimal amount of pre-processing and data wrangling. After Effects is not backward compatible with older versions, so it’s a good idea to keep your copy of After Effects CS4 installed so you can work on your existing projects and access your 32-bit plug-ins.
