As you work on an animation, you will want to preview the playback at a speed close to final production speed. To save time while previewing, you need to balance the quality of graphics with playback performance. You can also turn on display options to help you visualize the flow of a character’s motion.
Ideally, you should be able to click the Play forwards button and your animation would play back full-screen, fully shaded, and in real-time without dropping any frames. Although this is possible with smaller animations, the more complex a scene is, the more computations required before displaying each frame. For tips that can improve playback performance, see Optimize your scene for playback.
You can customize that playback of your animation by setting the Time Slider, Playback, Animation, and Sound preferences. To edit these options, go to the Playback options in Window > Settings/Preferences > Preferences. See Edit animation preferences.
With motion trails, you can display and edit the trajectory of an object. Motion trails work with objects that are animated by keyframe animation, deformers, motion capture, and expressions. You can create the motion trail before you animate an object or after. See Motion trails and Create an editable motion trail.
You can also playblast to preview you the animation in your scene. See Playblasting animation.
