After Effects Move One Keyframe Render the Whole Thing Again

Working with keyframes in Adobe Later on Effects is one of the easiest and most fundamental means to add more dynamic actions to your projects and brand them popular. You can create them with just a click, and adjust them nearly as easily. Since they're so valuable, y'all tin can make yourself more than valuable as an creative person by learning how to utilize them for your projects. Here's how.

Keyframe Overview

Since videos and animations are made upwards of frames, a keyframe is a marking (a diamond symbol in almost cases) that'due south created at a specific fourth dimension for a specific layer property'due south value. This can be for position (shortcut = P), scale (Southward), rotation (R), opacity (T), ballast signal (A), or other properties in furnishings and plugins. Typically, at least ii keyframes are used to create a change with a holding'south value over time. 1 is placed at the first of your change, and one at the cease with the new value.

Adding Keyframes

To create a keyframe, select the layer property and click on the stopwatch.* A keyframe volition appear at the current time indicator (CTI) on your selected belongings. Now your belongings is agile, denoted by a blueish stopwatch. When a layer property is agile, any alter you make to the layer value automatically adjusts the current keyframe or creates a new keyframe with that change.

When it'southward inactive, there are no keyframes, and any adjustments will keep the value the aforementioned for the unabridged duration of the layer. 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).

*Tip: Y'all can also create a keyframe past hitting alt/option + (property shortcut), or you tin can get upward to Breathing > Add (holding proper name) keyframe.

Removing and Moving Keyframes

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 information technology volition be removed. To remove all keyframes, click on the blue stopwatch and every keyframe will be deleted.

You tin move the keyframe correct or left in the timeline by merely clicking and dragging it to your preferred spot.

Adjusting Keyframe Values

Twirl down the triangles next to the layer and transform backdrop. The blue numbers are each belongings's values, as well every bit the value of the keyframe at that time (if there is i). You tin can click and drag them left or correct to increase or decrease the value*, or you can click and manually type in the value you want.

If y'all merely see one holding or value, you can hit shift + (property shortcut) to bring it up, in addition to the one you're seeing. View all your keyframes by striking U (a.k.a. the überkey), and view all modified keyframes in your projection past hitting U+U (that'southward U twice).

*Tip: You tin can adjust the values more than slowly by holding command/control while dragging, and y'all tin can adjust them more quickly by holding shift while dragging.

Keyframe Interpolation

Interpolation (a.one thousand.a. "tweening") sounds fancy, just it's basically what Later on Furnishings does between keyframes on an animation, movement, or other value change. About of the time, AE does a fine job figuring out what should happen between keyframes, merely sometimes your media tin can drift or motion in unwanted directions or speeds because of interpolation issues. There's a lot to go over with interpolation, but here are the broad strokes:

Spatial interpolation is how your object moves in space, and is adapted in the chief limerick window. Temporal interpolation is how your object moves in fourth dimension and is adjusted in the timeline (correct-clicking on keyframes). There are several types of interpolation methods for both, and AE automatically sets spatial interpolation to Auto Bezier (y'all can alter this in your settings).

Spatial Interpolation
To change the spatial interpolation, select a keyframe in the timeline. It should bring up the keyframe(due south) as a box on your chief limerick window. The dotted lines are the movement paths. If you lot want to keep the movement straight and uniform, and so keep the spatial interpolation linear. For non-linear move, right-click on the keyframe and pick i of the other options until 2 solid lines with dots (a.yard.a. bezier handles) appear at the ends. Drag the niggling dots to create your desired path shape.

Imagine you want to breathing this kid downwards this slide and then flying off into the air. Each interpolation method makes the kid take a different path. Here are the options:

Hither they are in motion:

You can see that a curved path matches the shape of the slide much better. This makes the animation expect a lot more natural, and then employ the one that fits best with your project.

Temporal Interpolation
For temporal interpolation, you can go on the time change compatible with the linear (default) setting, or you lot can right-click on the keyframe in the timeline and set each one to gradually showtime and/or terminate with diverse speeds. This is controlled with the other settings (Bezier, Continuous Bezier, Linear, Auto Bezier). You tin likewise create a hold to go along information technology in place until the next one, if there is one. Hither's what each method looks similar:

Finally, correct-clicking and selecting "rove across time" will smooth out whatsoever inconsistent speeds between your called keyframes. Just select any/all keyframes you want to modify and you'll see them plow into little circles. Play it back to brand sure it looks nice and smooth.

Example #1: The Ken Burns Outcome

Documentary filmmaker Ken Burns is notorious for animating still photos in his films. They movement from side to side, upward and down, or scale up or down as the narration discusses the subject area in the photo. We're going to mimic this by adding some standard keyframes.

Import your prune into your projection, then create a new composition based on that clip's settings. Next, gear up the CTI to the first frame of the video and open the Transform controls. Create new keyframes for scale and position.

Now move to the last frame of the video, scale the prune up 5%, and change the position by at least twenty-thirty pixels to be able to find the change. Play it back and meet what you've got.

Example #2

For the adjacent example, we're going to add some temporal interpolation. Take the same prune yous've already keyframed, and select and correct-click on the first gear up of keyframes. Go to Keyframe Assistant > Easy Ease Out. And so go to the last set and select "Easy Ease In."

This will brand the movements more gradual and natural, which is very important when you desire your graphics to look well-integrated. Think of animation like a motorcar — cars go from 0 so gradually speed upwardly to the cruising speed, then gradually dull back downwards and stop. Without interpolation, animations will be more rigid. You lot can employ this equally a guide.

To make the movement curved, click on the position keyframe and become to the main composition window. Correct-click the keyframe and open the keyframe interpolation window. Fix the spatial interpolation to Bezier, and so drag the niggling dot for each keyframe to create the motility path you lot want. Play it back with the curved paths and encounter what you call up.

Now that you've washed some basic keyframing, you can experiment with other interpolation types and more than circuitous movements and animations. Once you lot get more comfortable with keyframing, y'all can basically move and breathing annihilation you can think of!
