D Motion Graphics Foundations: Workspace, Layers, and Keyframe Thinking

The Core Building Blocks You’ll Use Every Time

Most 2D motion graphics projects—no matter the style—are built from the same fundamentals: a canvas (often called a composition), a frame rate that defines timing, a resolution that defines pixel dimensions, a stack of layers, and a set of transform properties that can change over time using keyframes. If you understand how these pieces connect, you can animate almost anything.

Guided Tour: A Typical 2D Motion Graphics Interface

Different apps label things slightly differently, but the layout is usually consistent. The goal is to know where to look when something feels “wrong.”

1) The Viewer / Canvas Panel (where you see the result)

This is the visual stage. You’ll usually find controls for zoom, safe margins, grid/guides, and sometimes a “current time” indicator. When you select a layer, you may see on-canvas handles for moving, scaling, and rotating.

• What to watch: Are you viewing the correct composition/canvas? It’s easy to open a nested comp or a different scene by accident.
• Practical habit: Set the viewer zoom to a predictable value (e.g., “Fit” or 100%) when judging position and edges.

2) The Timeline (where time and keyframes live)

The timeline shows time horizontally. A playhead (current time indicator) marks the exact frame you’re viewing. Layers appear as horizontal bars, and keyframes appear as small markers on those bars.

• Time navigation: Scrub the playhead to preview motion; step frame-by-frame when aligning keyframes.
• Layer duration: A layer can start later or end earlier than the composition—so it may not be visible at certain times.

3) The Layer Stack (what’s in front, what’s behind)

Layers are stacked vertically. Typically, higher layers appear in front of lower layers. This is crucial for motion graphics where elements overlap.

• Common confusion: If an object “disappears,” it might be behind another layer, not actually gone.
• Practical habit: Name layers clearly (e.g., Shape_Dot, BG, Text_Title) so you animate the right one.

4) The Properties / Inspector Panel (what you can change)

This panel lists properties for the selected layer: transform controls (Position, Scale, Rotation, Opacity), and sometimes more (effects, shape path controls, text settings). Many apps also allow you to “reveal animated properties” so you only see what has keyframes.

• Key idea: You don’t animate “the layer” in general—you animate specific properties on that layer.
• Practical habit: Before setting keyframes, confirm the correct layer is selected and the correct property is targeted.

Composition Settings: Frame Rate, Resolution, Duration

Composition settings are the foundation. If they’re wrong, animation can feel off even if your keyframes are correct.

Frame rate (fps)

Frame rate defines how many frames make up one second of time. Common choices include 24, 25, 30, and 60 fps. Higher fps can look smoother, but also increases render and preview load.

• Timing example: At 30 fps, 15 frames = 0.5 seconds. At 60 fps, 30 frames = 0.5 seconds.
• Practical guideline: Pick a frame rate early and keep it consistent across comps in the same project unless you have a specific reason.

Resolution

Resolution is the pixel size of your canvas (e.g., 1920×1080 for HD). It affects how crisp graphics appear and what your final export matches.

• Practical guideline: Match your intended delivery (social, web, presentation) and avoid resizing late unless necessary.

Duration

Duration is how long the composition lasts. You can animate beyond a layer’s length, but you can’t see beyond the composition’s end.

• Practical guideline: Set a comfortable duration for the exercise (e.g., 5 seconds) so you have room to animate.

Layers and Transform Properties: What You Actually Animate

In 2D motion graphics, most motion starts with transform properties. Even complex animations often begin as simple transforms, then get refined with easing and secondary motion later.

Transform properties (the essentials)

• Position: Where the layer is on the canvas (usually X and Y coordinates).
• Scale: Size of the layer (often percentage-based).
• Rotation: Angle of the layer (degrees).
• Opacity: Visibility from transparent (0%) to fully visible (100%).

Many tools also include an Anchor Point / Pivot that determines the center of rotation and scaling. If rotation looks “weird,” the anchor point is often the reason.

Keyframe Thinking: How Animation Is Defined

A keyframe stores a property value at a specific time. Animation happens because the software calculates the in-between values between keyframes (often called interpolation).

Keyframe logic in one sentence

If you set Position at time A and set a different Position at time B, the layer moves from the first position to the second over that time span.

A concrete example (Position)

Imagine a circle:

• At 0:00 (time A), Position = (200, 540)
• At 2:00 (time B), Position = (1720, 540)

The circle travels horizontally across the screen over 2 seconds. If you add more keyframes, you create a path with multiple changes in direction or speed.

Opacity example (fade)

• At 0:00, Opacity = 0%
• At 1:00, Opacity = 100%

The circle fades in over 1 second. Combine this with Position and you get “move while fading in,” a very common motion graphics pattern.

Two beginner rules that prevent most mistakes

• Rule 1: Always place the playhead first, then change the property value (so the keyframe lands where you intend).
• Rule 2: If you don’t see motion, check whether you created two different values at two different times. One keyframe alone does not create change.

Checkpoints: Common Beginner Errors (and Fast Fixes)

Error: Animating on the wrong layer

Symptoms: Something else moves, or nothing seems to happen to the object you intended.

• Check: Is the correct layer highlighted/selected in the timeline?
• Check: Are you changing the property on the correct layer (e.g., Shape Layer vs. a parent/group inside it)?
• Fix: Rename layers and lock layers you’re not editing to avoid accidental keyframes.

Error: Mismatched composition settings

Symptoms: Motion feels too fast/slow, exports don’t match preview, elements look cropped or scaled oddly.

• Check: Frame rate matches your intended output (and matches other comps you’re using).
• Check: Resolution matches your delivery size.
• Fix: Adjust comp settings early; if you must change later, verify timing and scaling afterward.

Error: Choppy previews (stuttering playback)

Symptoms: Playback skips frames, audio/video desync, motion looks jittery in preview but may render fine.

• Check: Preview quality (resolution) is set too high for your machine.
• Check: You haven’t cached/ram-previewed the section yet.
• Fix: Lower preview resolution, preview a shorter work area, hide heavy layers, or temporarily disable effects while animating.

Hands-On Exercise: Animate a Simple Shape’s Position and Opacity

This exercise builds the core muscle memory: select the right layer, set comp settings, place the playhead, set keyframes, change values, and preview.

Setup (composition/canvas)

1. Create a new composition/canvas.
2. Set Resolution to 1920×1080 (or your preferred HD size).
3. Set Frame rate to 30 fps.
4. Set Duration to 5 seconds.
5. Confirm you are viewing this composition in the viewer.

Create a shape layer

1. Add a simple shape (e.g., a circle) in the center of the canvas.
2. In the timeline, rename the layer to Circle.
3. Make sure Circle is selected.

Animate Position (left to right)

1. Move the playhead to 0:00.
2. In the properties/transform section for Circle, enable animation for Position (this creates the first keyframe at 0:00).
3. Set the circle’s Position so it starts near the left side (keep it fully on-screen).
4. Move the playhead to 2:00.
5. Change Position so the circle ends near the right side (still on-screen). A second keyframe should be created automatically when you change the value.

Animate Opacity (fade in while moving)

1. Keep the playhead at 0:00.
2. Enable animation for Opacity to create an opacity keyframe.
3. Set Opacity to 0%.
4. Move the playhead to 1:00.
5. Set Opacity to 100% (a second opacity keyframe is created).

Preview and verify

1. Scrub the playhead from 0:00 to 2:00: the circle should move across while fading in during the first second.
2. Play a preview of 0:00–2:00. If playback is choppy, lower preview resolution or preview a shorter range.

Exercise checkpoints (debug like a pro)

• If the circle doesn’t move: Confirm there are two Position keyframes at different times with different values.
• If the circle doesn’t fade: Confirm there are two Opacity keyframes (0% at 0:00, 100% at 1:00).
• If keyframes appear on a different layer: Undo, select Circle, and redo the keyframes.
• If motion looks too fast/slow: Re-check comp frame rate and whether you placed keyframes at the intended timestamps.
• If the preview stutters: Reduce preview quality, shorten the preview range, and try again.

Optional mini-variations (same fundamentals)

• Fade out: Add Opacity keyframes at 2:00 (100%) and 3:00 (0%).
• Hold then move: Add a Position keyframe at 1:00 identical to the 0:00 value, then move at 2:00.
• Diagonal move: Change both X and Y in Position to move across and down.
