Preparing an Illustrator File for Animation

Topics Covered in This After Effects Tutorial:

Resizing Artboards & Vector Graphics, Setting up Layers for After Effects

Exercise Overview

Successfully preparing vector graphics designed in Illustrator for After Effects animation requires far more than simply converting from CMYK to RGB. Professional motion graphics workflows demand precise artboard sizing to match your target composition dimensions, strategic scaling of vector elements for optimal visual impact, and—critically—the systematic separation of design elements into individual layers for granular animation control.

This comprehensive exercise walks you through the exact preparation workflow used for the Noble Logo animation project, demonstrating industry-standard techniques that will elevate your motion graphics output. You'll learn to anticipate common import issues and establish a reliable preprocessing pipeline that saves hours of troubleshooting later in your After Effects timeline.

Resizing Artboards & Vector Graphics

When importing Illustrator files into After Effects, the artboard dimensions directly determine your composition size—a fundamental relationship that catches many designers off guard. Mismatched dimensions create scaling issues, resolution problems, and unnecessary complications in your animation workflow. Establishing the correct artboard size upfront prevents these downstream issues and ensures your vector graphics maintain crisp edges at any scale.

1. On the Desktop, navigate into Class Files > After Effects Class > Noble Logo > Assets and double–click noble-logo-to-prepare-CMYK.ai to open it in Adobe Illustrator.

   Make sure you are opening the to-prepare file in the Assets folder, not the similar one that's outside that folder!

2. To convert the file, go to File > Document Color Mode and choose RGB Color.

3. In the Tools panel on the left, choose the Artboard tool .

4. In the docked panels at the right of the screen, if you don't see the Properties panel, click on the Properties tab or go to Window > Properties.

5. In the Properties panel, notice that the Width (W) is 201.85 px and Height (H) is 127.74 px. These dimensions are significantly smaller than our target composition size, requiring immediate adjustment to prevent quality issues during animation.

6. We don't need to maintain its aspect ratio, so in between the W and H dimensions, make sure Maintain Width and Height proportions is unlinked.

7. Set W to 1920 px and H to 1080 px, the standard size for HD video (and the size of the composition we want to create in After Effects).

   TIP: You could also use the HDTV 1080 preset to set this size. For 4K projects, consider using 3840 x 2160 dimensions to maintain maximum quality for high-resolution deliverables.

8. To see the entire artboard on-screen, go to View > Fit Artboard in Window.

9. The dramatically larger artboard makes the logo appear insignificant—a common scaling challenge when adapting print designs for video formats. In the Tools panel, switch to the Selection tool .

10. Press Cmd–A (Mac) or CTRL–A (Windows) to select all the art.

11. Go to Object > Transform > Scale and:

    • In the field next to Uniform, type 550. (You'll need to experiment with this scaling factor based on your specific design and intended visual hierarchy.)
    • At the bottom, check on Preview to see how this change will look and ensure the logo maintains appropriate visual weight within the frame.

12. Click OK.

With your artboard properly sized and graphics scaled appropriately, you're ready to tackle the crucial step of layer organization—the foundation that determines how flexibly you can animate individual elements.

Setting up Layers to Individually Animate Elements in After Effects

Layer structure in Illustrator directly translates to your animation capabilities in After Effects. A single consolidated layer might look clean in Illustrator, but it severely limits your animation options—you can only transform, fade, or effect the entire group as one unit. Professional motion graphics work demands the ability to animate individual elements independently, creating sophisticated sequences where letters appear sequentially, shapes animate in choreographed patterns, and complex reveals unfold over time.

The following workflow demonstrates how to systematically convert grouped paths into individual layers while maintaining proper stacking order and visual relationships.

1. On the right of the screen, click on the Layers tab to switch to that panel. (If you can't find it, go to Window > Layers.)

2. Expand Layer 1 by clicking its triangle to reveal the nested structure beneath.

3. With Layer 1 selected, begin breaking up the nested <Group> elements by going to Object > Ungroup. This process separates grouped elements while maintaining their individual properties.

4. Complex illustrations often require multiple ungrouping passes. Press Cmd–Shift–G (Mac) or CTRL–Shift–G (Windows) twice more to fully flatten the group hierarchy.

5. With Layer 1 still selected, at the top right of the Layers panel click on the panel menu .

6. From the menu that appears, choose Release to Layers (Sequence). This powerful command automatically creates individual layers from each path or shape, establishing the foundation for independent animation control.

7. The panel now shows 21 layers, though initially only the first is a true layer—the others remain as sublayers. To convert sublayers into independent layers that After Effects can recognize, select multiple sublayers in the Layers panel:

   • Click on Layer 2
   • Hold Shift and click on Layer 21 to select the entire range.

8. Drag any selected layer name (such as Layer 21) down until a thick blue line appears at the bottom of the layer stack, as shown below. Release to convert all sublayers into independent layers that will import correctly into After Effects.

   

9. Select the now-empty Layer 1.

10. At the bottom of the Layers panel, click the Trash button to remove the empty container layer.

11. Since After Effects displays layers by name rather than thumbnail content, strategic naming becomes crucial for efficient animation workflow. In the Layers panel, double–click on the Layer 9 name to edit it.
12. Rename it to black square and press Return (Mac) or Enter (Windows) to apply the change.

13. The top layers (2–8) contain colored rectangles that will animate in sequence. Click on the circle (visibility toggle) next to each layer name to identify its position in the artboard and understand the visual hierarchy.

    Notice that some rectangles have bounding boxes larger than their visible shapes, indicating overlapping elements. For the sequential animation we're planning—where rectangles appear clockwise starting with blue—we need to maintain the current layer order to preserve these visual relationships.

14. Rename Layers 2–8 to reflect their intended animation sequence, using descriptive names that indicate both color and timing order:

    Layer 2:	red-05 (it will be 5th in the sequence)
    Layer 3:	yellow-03
    Layer 4:	darkOrange-06
    Layer 5:	green-02
    Layer 6:	blue-01
    Layer 7:	gold-07
    Layer 8:	orange-04

15. The remaining layers contain individual letters from "Noble Desktop" that are currently out of logical order. Proper sequencing now will streamline your animation workflow later. Drag layers up or down to reorder them, being careful not to accidentally nest one layer inside another. Simultaneously rename each layer with descriptive identifiers like red n or blue o. Your final layer structure should match this organization:

    

16. Your file is now optimally prepared for professional After Effects animation workflows. Save your work by going to File > Save As and:

    • Navigate into Desktop > Class Files > After Effects Class > Noble Logo > Assets.
    • Name the project yourname-noble-logo-prepared-RGB.ai to distinguish it from the original source file.
    • Click Save.

17. In the dialog that appears, ensure Version is set to match your After Effects version (Illustrator 2024 or later for current CC subscriptions) and click OK. Version compatibility prevents import issues and ensures all layer data transfers correctly.

18. Quit Illustrator to free up system resources for the intensive After Effects work ahead.
