Adobe After Effects P3: Adobe After Effects provides the core 2D and 3D tools for compositing, animation, and effects that motion-graphics professionals, Web designers, and video professionals need. After Effects is widely used for digital post-production of film, motion graphics, video multimedia, and the Web. | ADOBE AFTER EFFECTS 47 Classroom in a Book Now the hexagons quickly become very large as they enter the composition frame. You will continue to make adjustments to affect the appearance of their entry in the following procedures. Note The hexagons may appear larger than you expect at this stage. You ll correct this a little later in another procedure so that they look more like the sample movie. When collapsing the transformations in this case After Effects uses the scale of the source file to display this image rather than calculating the scale based on the reduced size of the hexagon layers in the previous composition Hexagon Build Pre-comp . The source file is plenty large enough to display the image at this size without sacrificing the image quality. Rotating the entire honeycomb The next step is to add a rotation that extends from the beginning 0 00 to the end 3 29 of the composition. You need the rotation keyframes at the same points in time as the scale keyframes you just added. You ll use some new techniques to simplify your task. 1 With the Hexagon 3 Bars Pre-comp layer selected and the Scale property still open press Shift R. The Rotation property opens but without replacing the Scale property display. 2 Move the current-time marker to 0 00 if it is not already there but this time try one of the following techniques Click the left keyframe navigation arrow for the Scale property to move the current-time marker to the first Scale keyframe at 0 00. Be careful not to click the check box. Keyframe navigation arrow Press J. LESSON 1 Creating 2D Elements from Hexagons 48 3 Click the Rotation property stopwatch to set a keyframe with values of 0 x 0 at 0 00 . 4 On the Scale property click the right keyframe navigation arrow to move the currenttime marker to the next Scale keyframe at 3 29. Or press either K or End. 5 Change the Rotation value to 90 . A second keyframe appears in the Rotation properties. 6 Press J or Home to move the .
