This project mirrors real-world motion graphics workflows where proper asset management and composition setup are critical to success. Before diving into animation techniques, you'll master the essential foundation skills of importing, organizing, and positioning content—skills that separate professional editors from amateurs.

Previewing the Final Video

1. Let's examine the final output you'll be creating. If After Effects is currently open, keep it running but switch to your Desktop to preview the completed project.
2. On the Desktop, navigate to Class Files > After Effects Class > Guitar Picks > Preview Movie and double–click Guitar Picks Square.mp4.
3. Play the video to see the complete animation sequence. Pay attention to the timing, visual effects, and how elements interact with each other.
4. Review the video multiple times to understand the motion graphics techniques we'll be implementing, then close it when you're ready to begin.

Setting up the Workspace

Proper workspace configuration is crucial for efficient After Effects workflows. Let's establish an optimal environment before beginning our project.

1. Launch After Effects.

2. Choose Window > Workspace > Standard.

3. Choose Window > Workspace > Reset "Standard" to Saved Layout to ensure all panels are positioned at their default locations and sizes for consistent tutorial results.

4. Maximize the After Effects window to utilize your full screen real estate:

   Mac:	At the top left of the window, click the green button (the third button).
   Windows:	At to the top right of the window, click the Maximize button (the middle button).

Getting Started—Creating a New Composition

Compositions are the foundation of every After Effects project. Think of them as containers where you'll arrange and animate your media elements. We'll create a square format composition optimized for social media platforms like Instagram.

1. Choose Composition > New Composition (or click the New Composition button in the center of the interface).

2. Configure the following settings carefully—do NOT click OK until all parameters are set correctly:

   • Next to Composition Name type in Guitar Picks Square
   • From the Preset menu choose HD • 1920x1080 • 29.97 fps
   • Uncheck Lock Aspect Ratio
   • Change Width to 1080 (creating a perfect square format)
   • Ensure the menu to the far right of Frame Rate is set to Drop Frame.
   • Verify Resolution is set to Full for maximum quality during editing.
   • For Duration type in 1500 and hit Tab to set it 0;00;15;00 (15 seconds).

   

3. Since square compositions are increasingly popular for social media content, let's save this configuration as a custom preset for future projects. To the right of the Preset menu, click the New Preset button .

4. Name it 1080 Square and click OK.

   Notice the Preset menu now displays your new custom preset, making it instantly available for future square format projects.

5. Now click OK to create the Composition.

6. Save your project immediately to establish a proper file management foundation. Choose File > Save As > Save As.

   • Navigate to Desktop > Class Files > After Effects Class > Guitar Picks.
   • Name it Your Name—Guitar Picks.aep.
   • Click Save.

Importing Files

In Adobe After Effects, importing establishes the connection between your external media files and your project. Unlike some applications that embed files directly, After Effects maintains links to your original assets, allowing for smaller project files and easier collaboration. This linking system requires careful file management—moving or deleting source files after import will break these connections, potentially disrupting your entire workflow.

Professional editors always import entire folder structures to maintain organization and ensure all related assets are available throughout the editing process.

1. In the Project panel at the top left of the interface, ensure you can read the complete composition name (Guitar Picks Square). If the text is truncated, locate the divider between the Name and column headers and drag it rightward until the full name is visible.

2. Choose File > Import > File (or press Cmd–I (Mac) or CTRL–I (Windows)).

3. Navigate to Desktop > Class Files > After Effects Class > Guitar Picks.

4. Click on the Media folder to select it (we're importing the entire folder structure).

5. Click Open (Mac) or Import Folder (Windows) to import the folder and all of its sub–folders into your project.

6. In the Project panel, click the reveal arrow next to the Media folder to reveal its contents.

7. Click on the Images folder to select it and press Return (Mac) or Enter (Windows) to make the name editable.

   NOTE: Double–clicking on a folder or footage item previews it rather than making it editable. Alternatively, CTRL–click (Mac) or Right–click (Windows) on a folder name and choose Rename from the contextual menu.

8. Rename the Images folder to 01—Images and press Return (Mac) or Enter (Windows) to finalize the change. This numbering system ensures folders remain organized alphabetically.

9. CTRL–click (Mac) or Right–click on the audio folder and choose Rename.

   • Type in 02—Audio
   • Click on any empty area of the panel or press Return (Mac) or Enter (Windows) to finalize the change.

10. Select the video folder and press Return (Mac) or Enter (Windows) to make the name field editable.

    • Type in 03—Video
    • Hit Return (Mac) or Enter (Windows) to finalize the change.

11. Now we'll flatten the folder structure by moving the organized folders out of the Media container. Click on the 01—Images folder to select it:

    • Hold Cmd (Mac) or CTRL (Windows) and click on 02—Audio and 03—Video to add them to your selection.
    • Release the modifier key before continuing.

12. With all three folders selected, drag them out of the Media folder to the root level of your project.

13. Click on the now-empty Media folder and press Delete (Mac) or Backspace (Windows) to remove it.

14. Save your progress: File > Save or hit Cmd–S (Mac) or CTRL–S (Windows).

Adding Files to a Composition & Positioning Them

Understanding the distinction between footage and layers is fundamental to After Effects mastery. Imported assets in your Project panel are considered footage or media—they're simply available resources. However, when you add footage to a composition, it transforms into a layer with independent properties, blend modes, and animation capabilities.

If you've worked with layer-based applications like Adobe Photoshop or Adobe Illustrator, the concept is similar but more powerful in After Effects. Each layer maintains temporal properties (timing and duration) alongside spatial properties (position, scale, rotation), opening up infinite creative possibilities.

1. In the Project panel, click the arrow to the left of the 01—Images folder to reveal its contents.

   NOTE: You can also double–click on a folder name to reveal its contents.

2. Drag background four picks.jpg into the left side of the Timeline (the layer area), as shown below:

   

3. In the Timeline, CTRL–click (Mac) or Right–click (Windows) on the background four picks.jpg layer and choose Rename.

   NOTE: You can also press Return (Mac) or Enter (Windows) to make the name field editable.

4. Type in background and hit Return (Mac) or Enter (Windows) to finalize the change. Clear, descriptive layer names are essential for project organization.

5. When you add a layer to the Timeline, After Effects automatically centers it within the composition frame. Since this is a wide panoramic image, we need to reposition it to showcase the desired area. Click the arrow on the left of the background layer to reveal Transform.

6. Click the arrow next to Transform to reveal the individual transform properties.

7. Hover your cursor over the first Position value (horizontal position).

8. Drag to the right to scrub (dynamically change) the value. Continue dragging until the value reads 1240, positioning the guitar picks prominently in frame.

   You can also click directly on the first Position value, type 1240 and hit Return (Mac) or Enter (Windows) to apply the precise value.

9. Click the arrow next to Transform to hide the properties and clean up your timeline view.

10. Click the arrow next to the background layer to collapse the Transform section.

    In professional After Effects workflows, we access Transform properties constantly. Using interface arrows for every adjustment becomes inefficient and slows down creative momentum. From this point forward, we'll primarily use keyboard shortcuts to streamline our workflow and work at professional speeds.

Scaling & Rotating

Now we'll add our hero element and demonstrate essential transform controls that form the foundation of motion graphics work.

1. From the Project panel, drag pink-pick.jpg into the left side of the Timeline, positioning it above the background layer.

2. With the pink-pick.jpg layer highlighted in the Timeline:

   • Hit Return (Mac) or Enter (Windows) to make the name editable.
   • Rename it photo1 for easier identification
   • Hit Return (Mac) or Enter (Windows) again to finalize the change.

3. This image exceeds our composition dimensions of 1080 × 1080 pixels, requiring us to scale it appropriately for our square format.

   With the photo1 layer selected, press the S key to instantly reveal the Scale property.

4. Hover over the first Scale value and drag leftward until it reads 42% (or click on the value and type 42 directly).

   NOTE: The horizontal and vertical scale values remain proportionally linked thanks to the chain link button to the left of the first scale value. This prevents unwanted distortion.

5. With the photo1 layer still selected, press the R key to reveal the Rotation property.

6. Set Rotation to 0x-16° (note the negative value for counterclockwise rotation).

   NOTE: Rotation displays as two values. The first value represents complete 360° rotations (used primarily for animated spins), while the second value indicates the current rotational angle. When the angle exceeds 360°, the first value automatically increments.

7. Save your progress: File > Save or hit Cmd–S (Mac) or CTRL–S (Windows).

Understanding Drop Frame Vs. Non–Drop Frame Timecode

Timecode formatting might seem like a technical detail, but choosing the wrong format can cause significant problems in professional workflows. The distinction is visible in the punctuation: semi–colons indicate drop frame timecode, while colons indicate non-drop frame.

Drop frame timecode employs a sophisticated counting algorithm that periodically skips frame numbers (not actual frames) to maintain synchronization with real-world clock time. This system compensates for the fact that NTSC video runs at 29.97 fps rather than exactly 30 fps—a legacy of color television broadcasting standards.

For broadcast television, cable, and streaming content destined for North American markets, drop frame timecode is mandatory and ensures accurate program timing. For web content, social media, or international distribution, the choice is less critical, though drop frame remains the safer default for most professional applications in 2026.

Linking Vs. Embedding Files

Understanding file management in After Effects is crucial for maintaining project integrity and enabling collaborative workflows. The application exclusively uses a linking system rather than embedding media directly into project files.

When you link files (After Effects' only option), you create dynamic connections between your project and the original source files. This approach offers several professional advantages: smaller project file sizes, the ability to update source files and see changes reflected automatically, and easier collaboration since team members can access the same linked assets. However, this system requires disciplined file management—relocating or deleting source files breaks these connections, potentially corrupting your entire project.

Embedding, by contrast, places complete copies of files within the project document. While this ensures portability, it creates massive file sizes and prevents updates to source materials from flowing through to your compositions.

In After Effects, only elements created within the application—such as compositions, text layers, and shape layers—are truly embedded in your project file. All imported media maintains external links, making proper asset organization and backup procedures essential for professional workflows.
