About Motion and Motion
Motion also supports audio files, and includes tools for basic audio mixing, enabling you
to create a soundtrack for your project and make timing decisions based upon the interplay
of audio and visual elements. You can animate images, filters, behaviors, and other
elements to create elegant and precise compositions. Furthermore, you can retime your
footage using optical-flow technology to create special effects such as stutter and flash
2D and 3D Compositing Tools
Any time you have more than one image layer onscreen, you must employ some version
of compositing to combine the elements. This might mean moving image layers onscreen
so they don’t overlap, adjusting the layers’ opacities so they are partly visible, or
incorporating blend modes that mix the overlapping images in various ways. Compositing
is fundamental to motion graphics work. Fortunately, Motion makes it easier than ever
before, allowing you to control layer order, lock and group layers, and apply more than
25 different blending options to create unique effects.
You can also mix 2D and 3D groups in a single project, combining basic compositing
techniques with complex 3D animations.
Special Effects Tools
You can further enhance your motion graphics projects by employing many of the same
tools used in movies to combine dinosaurs with live actors, sink luxury liners in the ocean,
or create space battles. Motion elegantly handles many special effects techniques,
including keying (to isolate an object shot against a solid-colored background), masking
(to hide wires or other objects that should not be seen in the final image), keyframing
(to animate onscreen objects), and particle systems (to simulate natural phenomena such
as smoke, fire, and water).
