Summary of the video (Project window & File/Layer workflow in After Effects)

Goal of the session

• Learn how to use the Project window.
• Understand Project/File Blocks—what files live where, and how they become usable.

Purpose of the Project window

• Before working, you must import key components into the Project window.
• If assets are not imported into Project, you can’t use them immediately.
• Your speed depends heavily on how well you organize the project.

---

Importing files into the Project window

Methods to import

• Double-click in the Project panel
• Use the File menu
• Keyboard shortcut: Ctrl+R
• Right-click the panel (or even empty space) to access import options

Media notes

• The Project can show image, sound, and video files.
• Some video files may be unsupported depending on codecs.
• The instructor suggests testing support based on codec behavior later.

Media preview and image properties

What you see when selecting an image

• A preview appears at the top of the Project window.
• The example format information may show things like JPG.

Pixel/conversion concepts (from subtitles)

• Image resolution examples mentioned: 640 × 500 (and a subtitle artifact referencing “800 cells”).
• Square pixels meaning 1:1 pixel aspect ratio, contrasted with implied standards.
• References to common 8-bit color concepts.

---

Creating a canvas (composition) for editing

How to create a new composition

• Go to Composition > New > (create an HD-sized comp)

Example settings shown

• 1280 × 720
• Frame rate: 30
• Pixel aspect: square pixels
• Background: black
• Duration/time: described as “drilling” (subtitle artifact)

Resulting composition

• The example composition is named “0 Days”.
• Conceptually:
  • Composition window = main workspace
  • Project window = holds assets

---

Understanding “Project” vs “Composition” (Footage vs Layers)

• Project window contents: images, audio, video, solids, and text-related items/layers created from templates.
• Composition window (canvas): where you place and organize elements for actual editing.
• Naming distinction:
  • Files not yet placed into the comp are referred to as “Footage.”
  • Once placed into the comp, they become “Layers.”

---

Importing and placing assets (Layers window via drag & drop)

Drag behavior

• You can place dragged items wherever you want.
• If you drag into the Layers window and release, it often lands in the exact center.

Selection matters

• If a layer isn’t selected in the Layers panel, you can’t edit it.

Deleting/replacing

• The workflow includes selecting and using Delete to remove assets.

---

Layer timing: timeline bar, start time, and duration

Navigation concepts

• Use the timeline cursor and playback control with Space.
• Additional navigation:
  • Home = jump to the beginning
  • A “&” key behavior is mentioned (subtitle unclear), described as jumping to the last time

Layer “lifespan”

• An image layer exists only where its timeline segment exists.
  • Example: if placed starting at 3 seconds, it appears at the 3-second mark.
  • If the layer duration is short, it disappears when its segment ends.

Video timing behavior

• For video, you see only the region corresponding to the visible/trimmed time span.
• If trimmed/shortened, the “middle” can be omitted and playback behavior changes accordingly.

Key rule emphasized

• For time-based sources (video/audio), you must import/trim to the correct section so the correct time segment is visible.

---

Transformations (position/scale/rotation/transparency)

Tools and where transforms appear

• The instructor shows a basic selection transform tool (subtitle artifact).
• In the Layers panel, each layer’s expanded controls include a Transform group.

Transform controls listed

• Center
• Position
• Size/Scale
• Rotation
• Transparency

Position

• Move along X/Y using mouse interaction on the panel.
• Shift helps constrain movement (e.g., horizontal-only / axis constraints).

Scale and aspect ratio

• Discussion includes maintaining aspect ratio vs distortion.
• Shift is mentioned as a way to restore/maintain correct aspect ratio when something is distorted.

Rotation

• Rotate by dragging and/or entering numeric values.

Transparency values

• 0% = invisible
• 50% = half transparent
• 100% = fully visible

---

Layers panel controls: blending, timing, and visibility

Common expanded sections include

1. Layer visibility-style controls (switch/eye-like controls)
2. Compositing mode categories (labels mentioned, with some subtitle mixing):
   • Blending, Transform, Easing, Track, and Matte
3. Time-related controls (start/end points and other timeline properties; wording varies due to subtitles)

Playback speed concept

• If playback speed is set to a fraction like 50%, it’s described as “twice as slow.”
• 200% is described as “twice as fast.”

---

Eye / speaker / solo / lock icons

• Eye icon: toggles layer visibility
• Speaker icon: toggles layer audio
• Solo button:
  • Useful when many layers exist
  • Makes only the selected layer visible (and may further restrict visibility to specific layers)
  • Helps focus when compositions are dense
• Lock icon:
  • Prevents editing/selection of that layer
  • Helps avoid accidentally manipulating layers (especially above/below)

---

Editing names and shortcut language gotchas (Korean vs English)

Renaming

• Rename layers/assets by pressing Enter (in Project or Layers panel).
• Important behavior:
  • Renaming in After Effects does not change the original external filename—only the name inside After Effects.

Shortcut warning

• Keyboard shortcuts only work in English.
• If typing names in Korean, switch back to English, or shortcuts may not apply.
• The instructor notes beginners often miss that keyboard language affects shortcut behavior.

---

End-of-lesson takeaway

• Covered:
  • Project window workflow and importing assets
  • How “Footage” becomes “Layers” when added to a composition
  • Basic layer transforms and how timeline/layer duration affects visibility
• Next session preview:
  • The next lesson will focus on animation and keyframes.

Main speakers / sources

• Instructor/teacher (single presenter). No other sources or identifiable speakers mentioned.
