![]() ![]() Each interpolation method makes the kid take a different path. Imagine you want to animate this kid down this slide and then flying off into the air. Drag the little dots to create your desired path shape. For non-linear movement, right-click on the keyframe and pick one of the other options until two solid lines with dots (a.k.a. If you want to keep the movement straight and uniform, then keep the spatial interpolation linear. It should bring up the keyframe(s) as a box on your main composition window. To change the spatial interpolation, select a keyframe in the timeline. There are several types of interpolation methods for both, and AE automatically sets spatial interpolation to Auto Bezier (you can change this in your settings). Temporal interpolation is how your object moves in time and is adjusted in the timeline (right-clicking on keyframes). Spatial interpolation is how your object moves in space, and is adjusted in the main composition window. There’s a lot to go over with interpolation, but here are the broad strokes: Most of the time, AE does a fine job figuring out what should happen between keyframes, but sometimes your media can drift or move in unwanted directions or speeds because of interpolation issues. ![]() “tweening”) sounds fancy, but it’s basically what After Effects does between keyframes on an animation, movement, or other value change. *Tip: You can adjust the values more slowly by holding command/control while dragging, and you can adjust them more quickly by holding shift while dragging. the überkey), and view all modified keyframes in your project by hitting U+U (that’s U twice). View all your keyframes by hitting U (a.k.a. If you only see one property or value, you can hit shift + (property shortcut) to bring it up, in addition to the one you’re seeing. ![]() You can click and drag them left or right to increase or decrease the value*, or you can click and manually type in the value you want. The blue numbers are each property’s values, as well as the value of the keyframe at that time (if there is one). Twirl down the triangles next to the layer and transform properties. You can move the keyframe right or left in the timeline by just clicking and dragging it to your preferred spot. To remove all keyframes, click on the blue stopwatch and every keyframe will be deleted. To remove a single keyframe, simply select it and delete, or select it and click the blue keyframe navigation button (the blue diamond to the left of your layer) and it will be removed. *Tip: You can also create a keyframe by hitting alt/option + (property shortcut), or you can go up to Animate > Add (property name) keyframe. To create a keyframe without changing a value, copy/paste the keyframe at your new position, or click on the gray keyframe navigation button (the gray diamond to the left of your layer). When it’s inactive, there are no keyframes, and any adjustments will keep the value the same for the entire duration of the layer. When a layer property is active, any change you make to the layer value automatically adjusts the current keyframe or creates a new keyframe with that change. Now your property is active, denoted by a blue stopwatch. To create a keyframe, select the layer property and click on the stopwatch.* A keyframe will appear at the current time indicator (CTI) on your selected property. One is placed at the beginning of your change, and one at the end with the new value. Typically, at least two keyframes are used to create a change with a property’s value over time. This can be for position (shortcut = P), scale (S), rotation (R), opacity (T), anchor point (A), or other properties in effects and plugins. Since videos and animations are made up of frames, a keyframe is a mark (a diamond symbol in most cases) that’s created at a specific time for a specific layer property’s value. #Active timer in after effects how to#Since they’re so valuable, you can make yourself more valuable as an artist by learning how to utilize them for your projects. You can create them with just a click, and adjust them almost as easily. Working with keyframes in Adobe After Effects is one of the easiest and most fundamental ways to add more dynamic actions to your projects and make them pop. ![]()
