You can control the speed of your animation by moving keyframes temporally on the timeline or spatially in the composition panel. I’ll select continuous bezier and then adjust my bezier handles accordingly. I have four methods from which to choose, including linear, bezier, continuous bezier, and auto bezier. The turn is very abrupt, so I want to change the interpolation method of my middle keyframe to make the turn smooth. Spatial (space) relates to the keyframes in the composition panel, while temporal (time) references keyframes on the timeline.įor this example, I have my plane flying into the screen, making a sharp turn, and flying up out of frame. You’ll notice you have both spatial and temporal interpolation options. To take a look at your interpolation methods, select a keyframe and go to Animation > Keyframe Interpolation.

When you use two keyframes on a layer, After Effects interpolates the values between the two.

If I do this to both position and rotation keyframes, my plane will now barrel roll from the right side of the screen to the left. To do so, I can select my keyframes and go to Animation > Keyframe Assistant > Time-Reverse Keyframes. After Effects offers me a way to quickly and easily reverse these keyframes. In my last example, I made my plane barrel roll from the left side of the screen to right with a few simple rotation and position keyframes. Use position keyframes to have an object travel from left to right, or up to down. For instance, you can add scale keyframes to make a layer slowly scale up or down.

Being able to quickly adjust keyframe properties and values is important in animation.Īdding multiple keyframes of differing values to a property brings that property to life, and usually in a linear fashion. Using the dialogue box, I can have more precise controls, including percentages and other specific measurements. However, if I double-click directly over a keyframe, I get a dialogue box to assist me. Usually, I would make adjustments to the values straight here in the composition panel.

Adding two keyframes to a layer at different times with differing values will bring that property to life.įor this example, I’m going to adjust the rotation and position values of my airplane, making it perform a barrel roll. In After Effects, you use keyframes when you want a value of a layer to change over time. We'll use these advanced methods to bring an airplane graphic to life. We'll focus on five methods in particular, including precisely editing values, reversing time, changing interpolation, adding roving keyframes, and working with expressions. Let’s take a look at a few advanced tips and tricks when it comes to working with keyframes in After Effects. Knowing how to apply and manipulate them will help you to become a more seasoned motion graphics artist. Keyframing is one of the most important and powerful features of Adobe After Effects.
