Exercise Overview

This comprehensive exercise demonstrates professional multi-layer animation techniques by importing a complex PSD containing a 16-photo tiled grid for a movie intro sequence. You'll learn to create visually compelling animations by randomizing entrance timing, orchestrating sophisticated exit sequences, and leveraging null objects for efficient multi-layer control. These techniques are essential for modern motion graphics work, where managing dozens of layers simultaneously is common. Throughout this exercise, you'll also master Timeline organization strategies that scale effectively to large, complex projects—a critical skill for professional After Effects artists working on broadcast and streaming content.

Previewing What You'll Make in This Exercise

1. Ensure yourname-Movie Intro.aep remains open in After Effects. If you've closed it, reopen it now. We strongly recommend completing the previous exercise (4A) before proceeding, as this builds directly on those foundational techniques. If you haven't finished it, follow these steps:

   • Open Movie Intro-Ready for Photo Tiles.aep (located in the Movie Intro > Finished AE Projects folder).
   • Save the file as yourname-Movie Intro.aep in the Movie Intro folder.

2. Navigate to Desktop > Class Files > After Effects Class > Movie Intro > Finished Clips and double-click Movie-Tiles.mov to examine the target animation.

3. Study the video carefully, noting these key animation phases (scrub the playhead slowly for detailed analysis):

   • Randomized Entrance: 16 photos arranged in a precise grid begin with individual photos fading in at staggered intervals and dropping into their final grid positions—this organic randomization prevents the mechanical feel of synchronized animation.
   • Unified Scaling: Once positioned, all photos scale up together as a cohesive unit, demonstrating the power of null object control.
   • Orchestrated Exit: The exit sequence showcases sophisticated timing choreography—photos exit in diagonal waves starting from the bottom-left corner and progressing systematically to the top-right, creating a visually pleasing cascade effect that's far more engaging than random or linear exits.

4. Review the video multiple times to internalize these animation principles—we'll recreate each phase using professional techniques. Keep the reference open throughout the exercise for constant comparison.

Cropping Our Photoshop Layout

Professional motion graphics workflows often require assets at multiple scales to accommodate animation requirements. Since our design calls for photos to scale up to 120% of their final size, we've created the Photoshop layout at this larger dimension. Now we'll establish the correct starting frame size within Photoshop, ensuring seamless integration with our HD composition.

1. Launch Adobe Photoshop to begin our asset preparation workflow.

2. To save production time, we've prepared the base layout for you. Navigate to File > Open.

3. Navigate to Desktop > Class Files > After Effects Class > Movie Intro > Assets and double-click Movie Tiles-120 Scale Started.psd.

4. Create your working version by going to File > Save As and configure these settings:

   • Set Format (Mac) or Save as type (Windows) to Photoshop if it isn't already selected.
   • Navigate to Desktop > Class Files > After Effects Class > Movie Intro > Assets.
   • Name it yourname-Movie Tiles-120 Scale.psd and click Save.

5. Verify the current dimensions by going to Image > Canvas Size. The file should display 2304 × 1296 Pixels (select Pixels from the dropdown if needed). This represents exactly 120% of the standard 1920 × 1080 HD video dimensions.

6. To establish our animation starting point, crop the document to HD specifications by setting:

   Width:	1920 Pixels
   Height:	1080 Pixels

7. Click OK to apply the crop, establishing our HD canvas size.

8. When prompted with a clipping warning, click Proceed to confirm the operation.

   This crop reduces the canvas size while preserving the individual photo layers at their original 120% scale—they'll extend beyond the document boundaries, which is precisely what we need for our scaling animation. This technique ensures smooth scaling without quality loss.

Creating a Gridded Layout of Guides in Photoshop

Precision is paramount in professional motion graphics. The upcoming animation requires exact positioning of photo layers, and while After Effects offers guide functionality, Photoshop provides superior tools for creating perfectly distributed grid systems. By establishing our guide structure now, we ensure pixel-perfect alignment when we import our PSD, saving significant time during the animation phase.

1. Access View > New Guide Layout and configure these settings to create a precise 8 × 8 grid system:

   • Enable both Columns and Rows checkboxes.
   • Set both Number values to 8 for perfect symmetry.
   • Ensure all other fields remain blank—we want zero gutters for seamless tile positioning.
   • Click OK to generate the grid.

2. Preserve your work with File > Save.

3. With our Photoshop preparation complete, exit the application using Cmd–Q (Mac) or Ctrl–Q (Windows).

Scaling up Each Tile Using a Null Object

One of After Effects' most powerful features is the ability to control multiple layers simultaneously through parent-child relationships. Rather than tediously keyframing scale properties across 16 individual layers, we'll employ a null object as a master controller—a technique that's absolutely essential for efficient professional workflows when managing complex animations with numerous elements.

1. Return to After Effects, where yourname-Movie Intro.aep should remain open.

2. Import your prepared asset using Cmd–I (Mac) or Ctrl–I (Windows), or access File > Import > File.

3. Navigate to Desktop > Class Files > After Effects Class > Movie Intro > Assets and double-click yourname-Movie Tiles-120 Scale.psd.

4. Configure the import dialog with these critical settings:

   Import Kind:	Composition – Retain Layer Sizes
   Layer Options:	Merge Layer Styles into Footage

   NOTE: Only Composition import options preserve guide information—essential for our precision work. The "Retain Layer Sizes" option maintains our oversized photo layers while cropping the composition canvas, exactly what we need for our scaling animation.

5. Click OK to complete the import process.

6. In the Project panel, locate and double-click the yourname-Movie Tiles-120 Scale composition (identified by the filmstrip icon ) to open it in the Timeline.

7. Optimize the composition settings by going to Composition > Composition Settings and updating:

   Composition Name:	01-Movie Tiles
   Duration:	0;00;05;06

8. Apply the changes by clicking OK.

9. In the Timeline, select the NYC layer (topmost) to ensure our null object appears above it in the layer stack—proper hierarchy is crucial for effective null object control.

10. Create the master controller via Layer > New > Null Object.

11. Rename it Scale Null to clearly identify its purpose in the animation hierarchy. The following steps must be executed in precise order for proper scaling relationships.

12. Select the Scale Null layer and press S to reveal its Scale property.

13. Since we want all photos at their current size when the animation concludes, navigate to the final frame by pressing End (or Fn–Right Arrow) to reach 5;05.

14. Establish the end-state keyframe by clicking the stopwatch under Scale and set either value to 120%. This creates our target scale without immediately affecting the photo layers.

15. Select all photo layers by clicking Layer 2 and Shift-clicking Layer 17 to capture the entire range.

16. Establish the parent-child relationships by accessing the Parent & Link column dropdown for any selected layer and choosing 1. Scale Null. This makes all photos respond to our null object's transformations—a fundamental technique for complex animation control.

17. Create the initial keyframe by pressing Home (or Fn–Left Arrow) to return to 0;00.

18. Set the Scale Null layer's Scale to 100%. You'll immediately see all child photo tiles display black borders and their anchor points align with guide intersections—confirming our parent-child relationships are working correctly.

Randomizing the Order in Which the Photos Animate in

Natural, organic animation timing separates professional work from amateur attempts. Rather than having all elements appear simultaneously, we'll create staggered entrance timing that mimics realistic physics while maintaining visual interest. This randomization technique is widely used in broadcast and streaming content to create more engaging viewer experiences.

1. To simplify our animation workflow, we'll work backwards from the final position—a professional technique that ensures perfect alignment. Click the timecode display and enter 1. (including the period) to jump to 1;00 (1 second), marking the end of our entrance animation sequence.

2. Prevent accidental modification by locking both the Scale Null and BG layers. Click the empty boxes under the Lock column adjacent to these layer names.

3. Enable precision positioning by ensuring both Snap to Guides and Lock Guides are checked in the View menu. You may need to access the menu twice if both options are currently disabled.

   If guides become invisible, click the Choose grid and guide options button in the Composition panel's bottom-left corner and enable Guides.

4. Select any photo layer, then use Edit > Select All to select all unlocked layers. The locked null object and background layers remain unselected—exactly what we want.

5. Reveal the Position property by pressing P.

6. Add the Opacity property by holding Shift and pressing T.

7. Maintain selection of all layers throughout the next several steps—this is crucial for synchronized keyframe creation.

8. Create Position keyframes by clicking the stopwatch for any selected layer's Position property.

9. Similarly, enable keyframing for the Opacity property.

10. Navigate to the animation start point at 0;15 by clicking the timecode display and entering the value.

11. In the Composition panel, use the Up Arrow key to move all tiles upward by one and a half gridlines until the bottom row matches the position shown below. Use Shift–Up Arrow initially for faster 10x movement, then fine-tune with single arrow presses.

    

12. Set the starting Opacity to 0% for any selected layer—this will apply universally to all selected layers.

13. Create smooth deceleration by selecting the entire column of keyframes at 1;00.

14. Apply easing via Animation > Keyframe Assistant > Easy Ease In to create natural deceleration as elements reach their final positions.

15. Trim layer start times to 15 frames by positioning the playhead at 00;15 and pressing Option–[ (Mac) or Alt–[ (Windows). Alternatively, hover over each layer's left edge until you see the resize cursor and drag rightward.

16. Preview your work by pressing Spacebar—you should see synchronized entrance animation.

17. Now we'll add visual interest through randomization. Move the playhead to 1;00 to see all tiles in their final positions.

18. Clear all selections by clicking an empty Timeline area.

19. Ensure the Selection tool is active in the Tools panel.

20. In the Composition panel, Shift-click to select 8 photos distributed across the composition—choose tiles that create visual balance and interest.

21. Reorganize layer hierarchy by going to Layer > Arrange > Bring Layer to Front, moving all 8 selected layers to the top of the stack.

22. Position them correctly by choosing Layer > Arrange > Send Layer Backward so they appear below the Scale Null.

23. Create visual organization by changing the Label Color (under the tag icon ) of any selected layer to Orange, distinguishing this group from the remainder.

24. Ensure the In column is visible in your Timeline. If not, Ctrl-click (Mac) or Right-click (Windows) on a column header like "Layer Name" and select Columns > In.

25. Isolate this group by enabling Solo for any selected layer, allowing focused timing adjustments.

26. Clear selections with Edit > Deselect All.

27. Create randomized timing by setting each orange-labeled layer's In value to different odd numbers between 15-29 frames. We recommend using: 27, 15, 19, 29, 21, 17, 25, and 23 for optimal visual flow.

28. Scrub the playhead slowly to observe the randomized fade-in and drop animation—each tile now has unique entrance timing.

29. Disable Solo and clear selections by clicking empty Timeline space.

30. Complete the randomization for the remaining eight photo layers:

• Ensure the playhead remains at 1;00 for clear visibility.
• Scroll down to access the 8 remaining (non-orange) photo layers.
• Set their In column values using even numbers 14-30, spaced 2 frames apart. Try: 24, 20, 18, 22, 14, 26, 28, 16 for complementary timing.
• Preview using Spacebar and adjust timing values until you achieve a natural, flowing entrance pattern.
• Fine-tune individual In values across both groups until the animation feels organic and engaging.

1. Press Spacebar to preview the complete entrance sequence. You've successfully created a sophisticated, professional entrance animation with natural timing variation!

Organizing the Exit Animation's Diagonal Groups

Professional motion graphics often employ geometric patterns for exit sequences, as they provide visual coherence while maintaining viewer interest. The diagonal cascade we're about to create—progressing systematically from lower-left to upper-right—exemplifies this principle and is commonly used in broadcast graphics and streaming platform interfaces. Proper organization before animation is crucial for maintaining workflow efficiency.

1. Navigate to 3;00 to establish the start point for our exit animation sequence.

2. Select all photo layers using Cmd–A (Mac) or Ctrl–A (Windows).

3. Streamline the Timeline view by collapsing layer properties: select all photo layers, then click the down arrow next to any selected layer to hide property details and focus on layer organization.

4. Clear selections by clicking empty Timeline space.

5. Identify the first diagonal element by clicking the bottom-left photo tile in the Composition panel (the hamburger image)—this initiates our diagonal cascade pattern.

6. Position this layer at the bottom of the photo stack by dragging it to become Layer 17 in the Timeline, if it isn't already.

7. Clear all selections with Cmd–Shift–A (Mac) or Ctrl–Shift–A (Windows).

8. Continue building the diagonal sequence by selecting the next photo in the diagonal progression. In the Composition panel, this would be the tile positioned one row up and one column right from our starting position.
