Which panel provides the preview of the active composition and its safe zones?

  1. The Project panel
  2. The Composition panel Correct answer.
  3. The Effects & Presets panel
  4. The Timeline panel

Explanation

The Composition panel shows the visual result of the active composition, including previews, safe zones, and view controls. The Timeline panel manages layers and keyframes, while the Project panel stores assets.

Question 2Project setup, interface, and workflow

Which keyboard shortcut opens the Composition Settings dialog in After Effects on Windows?

  1. Ctrl+K Correct answer.
  2. Ctrl+Shift+K
  3. Ctrl+Alt+K
  4. Ctrl+N

Explanation

Composition Settings is opened with Ctrl+K on Windows or Command+K on macOS. This dialog controls frame rate, resolution, duration, and background color.

Question 3Project setup, interface, and workflow

Which action creates a new folder in the Project panel?

  1. Press Ctrl+Shift+C in the Composition panel.
  2. Click the New Folder button at the bottom of the Project panel. Correct answer.
  3. Choose Animation > Add Folder.
  4. Choose Layer > New > Folder.

Explanation

The Project panel has a New Folder button for organizing footage, compositions, and other items. Folders in the Project panel affect organization only, not rendering.

Question 4Project setup, interface, and workflow

Where do you change the number of undo steps that After Effects retains?

  1. Project Settings > General
  2. Composition Settings > Advanced
  3. Timeline panel menu > Undo History
  4. Preferences > General Correct answer.

Explanation

The Levels of Undo setting is found in Preferences > General. Increasing it allows more undo steps but can consume additional memory.

Question 5Project setup, interface, and workflow

What happens when you double-click a layer in the Timeline panel?

  1. The layer's source footage is deleted.
  2. The layer opens in the Layer panel. Correct answer.
  3. The layer is converted to a guide layer.
  4. The layer is added to the Render Queue.

Explanation

Double-clicking a layer in the Timeline opens it in the Layer panel, where you can view and edit that layer's contents independently of the composition. This is useful for editing precompositions and source layers.

Question 6Project setup, interface, and workflow

Which command imports a footage file into the current After Effects project?

  1. File > Open
  2. Composition > Add Footage
  3. File > Import > File Correct answer.
  4. Layer > New > Footage

Explanation

File > Import > File opens a dialog for bringing footage into the Project panel. Imported footage becomes a project item that can be used in compositions.

Question 7Project setup, interface, and workflow

Which setting changes the background color of a composition?

  1. Layer > Layer Settings
  2. Preferences > Appearance
  3. Composition Settings > Background Color Correct answer.
  4. Project Settings > Color Management

Explanation

The Background Color swatch is located in Composition Settings. This color appears in the Composition panel where no opaque layers cover the background.

Question 8Project setup, interface, and workflow

Which layer switch temporarily limits preview and rendering to selected layers?

  1. Shy
  2. Video
  3. Solo Correct answer.
  4. Lock

Explanation

The Solo switch isolates selected layers so other layers are not displayed or rendered while solo is active. It is useful for checking individual layers without deleting or hiding them permanently.

Question 9Project setup, interface, and workflow

Imported footage plays at the wrong speed because its frame rate was interpreted incorrectly. Which command sets the frame rate After Effects uses for that footage?

  1. Layer > Time > Time Stretch
  2. File > Project Settings
  3. Composition > Composition Settings
  4. File > Interpret Footage > Main Correct answer.

Explanation

Interpret Footage > Main lets you tell After Effects how to interpret a footage item's frame rate, pixel aspect ratio, and field order. Correcting the frame rate prevents unintended speed changes.

Question 10Project setup, interface, and workflow

What is the primary purpose of creating a proxy for a high-resolution footage item?

  1. To automatically color-correct the footage
  2. To convert the footage into a vector graphic
  3. To permanently replace the source with a lower-resolution file for final render
  4. To improve editing and preview performance while preserving the source for final render Correct answer.

Explanation

A proxy is a lower-resolution or otherwise simplified stand-in used to speed up previews and editing. The original source can still be used for final rendering when proxy use is disabled.

Question 11Project setup, interface, and workflow

Where can you clear the media cache database in After Effects?

  1. Edit > Purge > All Memory
  2. File > Dependencies > Collect Files
  3. Project Settings > Media
  4. Preferences > Media & Disk Cache Correct answer.

Explanation

The Media & Disk Cache preferences include controls for the media cache database and disk cache. Clearing the database can resolve issues caused by corrupted cached files.

Question 12Project setup, interface, and workflow

Which preference controls automatic project backups while you work?

  1. Preferences > General
  2. Preferences > Appearance
  3. Preferences > Auto-Save Correct answer.
  4. Preferences > Memory & Performance

Explanation

The Auto-Save preferences control whether After Effects automatically saves backup copies and how often it does so. These backups help recover work after an unexpected interruption.

Question 13Project setup, interface, and workflow

Which command gathers a project and its footage into a single folder for archiving or sharing?

  1. Composition > Pre-render
  2. File > Export > Add to Render Queue
  3. Edit > Purge > All Memory & Disk Cache
  4. File > Dependencies > Collect Files Correct answer.

Explanation

Collect Files copies the project and its dependent footage into a specified folder, making it easier to move or archive the project. It helps avoid missing-link problems on another system.

Question 14Project setup, interface, and workflow

A footage item is missing in the Project panel. Which command lets you point it to a new file on disk?

  1. Layer > New > Solid
  2. Composition > Add to Render Queue
  3. File > Replace Footage > File Correct answer.
  4. File > Import > Replace Footage

Explanation

Replace Footage > File lets you relink a missing or outdated footage item to a file on disk. The project item keeps its place in compositions while pointing to the new source.

Question 15Project setup, interface, and workflow

Which composition setting should match imported footage to avoid unintended stretching?

  1. Frame Rate
  2. Resolution
  3. Start Timecode
  4. Pixel Aspect Ratio Correct answer.

Explanation

Pixel Aspect Ratio describes the shape of pixels in the footage or composition. If it does not match the source, images can appear stretched or squeezed.

Question 16Project setup, interface, and workflow

What defines the range used for RAM preview and often for initial export in the Timeline?

  1. The composition duration
  2. The work area bar Correct answer.
  3. The playhead position
  4. The layer in-point and out-point

Explanation

The work area bar in the Timeline sets the range used for previews and can limit the rendered range. Dragging its ends adjusts which portion of the composition is processed.

Question 17Project setup, interface, and workflow

What does the Shy switch do to a layer in the Timeline panel?

  1. Disables its video output during rendering
  2. Locks it against editing
  3. Hides it from the Timeline view without removing it from rendering Correct answer.
  4. Soloes it during preview

Explanation

The Shy switch hides a layer from the Timeline panel when shy layers are hidden, reducing clutter. The layer still appears in the composition and renders normally unless another switch disables it.

Question 18Project setup, interface, and workflow

What is the effect of locking a layer in the Timeline panel?

  1. It hides the layer in the Composition panel.
  2. It prevents the layer from being selected or edited in the Composition panel. Correct answer.
  3. It disables all effects applied to the layer.
  4. It converts the layer into a guide layer.

Explanation

Locking a layer protects it from accidental selection and editing while keeping it visible and renderable. You must unlock the layer before making further changes to it.

Question 19Project setup, interface, and workflow

How do you apply an effect from the Effects & Presets panel to a selected layer?

  1. Press Ctrl+Shift+E in the Project panel.
  2. Drag the effect into the Render Queue panel.
  3. Choose File > Import > Effect.
  4. Double-click the effect name in the Effects & Presets panel. Correct answer.

Explanation

Double-clicking an effect in the Effects & Presets panel applies it to the selected layer and opens its controls in the Effect Controls panel. You can also drag an effect onto a layer in the Timeline or Composition panel.

Question 20Project setup, interface, and workflow

Changing the Composition panel resolution from Full to Half affects what?

  1. Project color depth
  2. Preview quality and speed only Correct answer.
  3. Layer pixel aspect ratios
  4. Final rendered output dimensions

Explanation

The Composition panel resolution setting changes preview quality and playback performance while you work. It does not change the final rendered dimensions or project color depth.

Question 21Project setup, interface, and workflow

Which location sets a project's color bit depth to 16 or 32 bits per channel?

  1. Composition Settings > Advanced Options
  2. Preferences > Display & Color Management
  3. Layer > Layer Settings > Color
  4. File > Project Settings > Color Correct answer.

Explanation

Project-wide color depth is configured in Project Settings under the Color settings. Higher bit depths provide more precision for color and effects processing.

Question 22Project setup, interface, and workflow

Which preference sets the default duration assigned to imported still images?

  1. Preferences > General > Levels of Undo
  2. Project Settings > Time Display
  3. Preferences > Import > Still Footage Correct answer.
  4. Composition Settings > Start Timecode

Explanation

The Still Footage preference controls whether imported stills receive a default duration or use the length of the composition. This default can be changed later by interpreting the footage.

Question 23Project setup, interface, and workflow

Which item is configured by Output Module settings rather than Render Settings in the Render Queue?

  1. Render quality and motion blur samples
  2. Composition resolution and layer quality
  3. Output format and video output Correct answer.
  4. Render time span and composition frame rate

Explanation

Render Settings control the rendered time span, resolution, frame rate, and quality options. Output Module settings control the output format, video and audio output, and related file options.

Question 24Project setup, interface, and workflow

Which command frees RAM and disk cache used by previews without deleting project assets?

  1. File > Save As
  2. File > Dependencies > Collect Files and Footage
  3. Edit > Purge > All Memory & Disk Cache Correct answer.
  4. Composition > Pre-render

Explanation

Purge commands clear cached previews, undo data, and related memory or disk cache. Purging does not delete footage or remove layers from the project.

Question 25Project setup, interface, and workflow

Which preference controls whether new layers start at time zero instead of at the current playhead time?

  1. Composition Settings > Start Timecode and Duration
  2. Preferences > Auto-Save and Undo Levels
  3. Preferences > General > Create Layers at Start Time Correct answer.
  4. Project Settings > Time Display and Frame Rate Options

Explanation

The Create Layers at Composition Start Time preference controls where newly created layers are placed in time. When enabled, new layers begin at the composition start rather than at the playhead.

Question 26Project setup, interface, and workflow

Which panel lists the effects applied to the currently selected layer together with their editable settings?

  1. Effects & Presets panel
  2. Render Queue panel
  3. Effect Controls panel Correct answer.
  4. Project panel

Explanation

The Effect Controls panel follows the current layer selection and shows each effect applied to that layer in order, with its parameters and stopwatches for animating them. Effects are found and applied from the Effects & Presets panel, but they are edited in the Effect Controls panel.

Question 27Project setup, interface, and workflow

Several panels are open and you want a single panel to temporarily fill the application window without altering the saved workspace. What should you do?

  1. Choose Window > Maximize Panel from the menu bar.
  2. Drag the panel tab to the center of the screen.
  3. Point at the panel and press the grave accent (`) key. Correct answer.
  4. Double-click the panel's tab.

Explanation

With the pointer over a panel, pressing the grave accent (`) key maximizes that panel to fill the application window, and pressing it again restores the previous arrangement. Because it is only a temporary view change, the saved workspace layout is preserved.

Question 28Project setup, interface, and workflow

You want time values throughout the project to be shown in frames instead of timecode. Where is this changed?

  1. Project Settings, via Time Display Style Correct answer.
  2. Timeline panel menu > Columns
  3. Composition Settings, on the Basic tab
  4. Preferences > Display, in the Time section

Explanation

Time Display Style is a project-level option inside the Project Settings dialog, and it switches the whole project between timecode and frames. Composition Settings and the preferences govern other properties such as dimensions, duration, and interface appearance.

Question 29Project setup, interface, and workflow

You need the Timeline panel to show or hide columns such as Switches, Modes, and Parent. Where are these column controls located?

  1. Preferences > Appearance
  2. Layer menu > Layer Settings
  3. Composition panel's View Options dialog
  4. Timeline panel menu > Columns Correct answer.

Explanation

Column visibility for the Timeline panel is controlled from that panel's flyout menu under the Columns submenu, where each column group can be toggled on or off. This changes only what the panel displays and does not modify any layer data.

Question 30Project setup, interface, and workflow

A footage item has an unusual frame size and frame rate, and you need a composition whose settings match it exactly with minimal manual entry. Which workflow accomplishes this?

  1. Dragging the footage item into the Timeline panel of an existing empty comp
  2. Composition > New Composition, then entering the width, height, and frame rate by hand
  3. Dragging the footage item onto the New Composition button Correct answer.
  4. File > Interpret Footage > Main on the footage item

Explanation

Dropping a footage item on the Create a New Composition button builds a composition that inherits that item's frame size, pixel aspect ratio, frame rate, and duration. This avoids transcription errors when the source format is nonstandard.

Question 31Importing, organizing, and managing assets

When you import a numbered PNG sequence into After Effects, which option in the Import File dialog keeps the files grouped as a single footage item?

  1. PNG Sequence Correct answer.
  2. Create Composition
  3. Import Folder
  4. Merge Layers

Explanation

Selecting the PNG Sequence option in the Import File dialog treats numbered stills that share a base name as one footage item. Without it, each file becomes a separate footage item, so the sequence cannot play as a movie until it is assembled manually. The numbering must be consecutive for the option to be available.

Question 32Importing, organizing, and managing assets

Which action imports an entire folder of footage as a new bin in the Project panel while preserving its contents?

  1. Choose File > Export > Add to Media Encoder Queue
  2. Choose File > Import > Placeholder and pick a folder
  3. Choose File > Import > File and select the folder Correct answer.
  4. Choose File > Dependencies > Collect Files and pick a folder

Explanation

In After Effects, choosing File > Import > File and selecting a folder imports that folder as a bin, with its files inside. This preserves the folder structure for organization. Import Multiple Files is for selecting individual files, and Placeholder creates synthetic media.

Question 33Importing, organizing, and managing assets

Which import option for a layered Photoshop file creates a composition with each layer as a separate footage item?

  1. Import As Footage
  2. Import As Placeholder
  3. Import As Merged Layers
  4. Import As Composition Correct answer.

Explanation

Choosing Import As Composition from the PSD import options creates a new composition and imports each Photoshop layer as its own footage item. Import As Footage flattens the layers into a single item. Import As Merged Layers is not the composition option.

Question 34Importing, organizing, and managing assets

A footage item in the Project panel shows a missing-file icon. Which command relinks it to a file on disk?

  1. File > Replace Footage > File Correct answer.
  2. File > Revert
  3. Layer > Transform > Fit to Comp
  4. File > Dependencies > Consolidate

Explanation

Replace Footage > File points the existing footage item to a new source file, and every composition that uses that item updates automatically. This is the standard way to relink offline media. Revert discards unsaved project changes and does not relink.

Question 35Importing, organizing, and managing assets

Which technique replaces the source of a selected layer in a composition while keeping its effects, masks, and keyframes?

  1. Choose File > Import > Placeholder
  2. Delete the layer and drag in new footage
  3. Choose Layer > New > Null Object
  4. Alt-drag new footage onto the layer Correct answer.

Explanation

Alt/Option-dragging footage from the Project panel onto a selected layer replaces the layer's source while preserving effects, masks, keyframes, and transforms. Deleting the layer first would discard those properties. The other commands create new items or layers rather than swapping the source.

Question 36Importing, organizing, and managing assets

Which command gathers a project and its footage into one folder for archiving or handoff?

  1. File > Save As
  2. File > Dependencies > Collect Files Correct answer.
  3. Edit > Purge > All Memory & Disk Cache
  4. File > Scripts > Run Script File

Explanation

Collect Files creates a new folder containing a copy of the project and the footage it depends on, which is useful for archiving or handoff. It can also include proxy versions. Save As stores only the project file, not the media.

Question 37Importing, organizing, and managing assets

Which workflow lets you edit with low-resolution versions while keeping full-resolution footage for final render?

  1. Use File > Reduce Project
  2. Enable Draft 3D in the Timeline panel
  3. Create and toggle proxies for footage items Correct answer.
  4. Set the Composition Settings resolution to Quarter

Explanation

A proxy is an alternate, usually lower-resolution file linked to a footage item; the Toggle Proxies button switches between proxy and full-resolution media. Proxies speed up editing while the final render can use the original files. Changing composition resolution only affects preview quality, not source media.

Question 38Importing, organizing, and managing assets

When importing a footage item with an alpha channel, what does the 'Straight – Unmatted' interpretation mean?

  1. Alpha is premultiplied against a white matte
  2. RGB values are not premultiplied by alpha Correct answer.
  3. Alpha is scaled to match the composition size
  4. Alpha is ignored and black is treated as transparent

Explanation

Straight (unmatted) alpha means the RGB channels have not been premultiplied by alpha, so semi-transparent edge pixels may show fringes if interpreted as premultiplied. The Alpha menu in Interpret Footage lets you match the file's actual encoding. After Effects renders most of its own outputs as premultiplied.

Question 39Importing, organizing, and managing assets

Where do you assign the project's working color space in After Effects?

  1. Composition Settings > Advanced tab
  2. Project Settings > Color tab Correct answer.
  3. Layer > Layer Styles > Color Overlay
  4. Preferences > Display > Color

Explanation

Project Settings > Color sets the working color space and bit depth used for color management in the project. Composition Settings and Preferences do not define the project working space. Layer styles are effects and do not control project color management.

Question 40Importing, organizing, and managing assets

A 30 fps clip plays too fast because AE interpreted it as 24 fps. Where do you correct this for that footage item?

  1. File > Interpret Footage > Main Correct answer.
  2. Composition > Composition Settings > Frame Rate
  3. Layer > Time > Time Stretch
  4. File > Project Settings > Timecode

Explanation

Interpret Footage > Main contains the Assume This Frame Rate setting, which changes how the source clip's frames are timed throughout the project. Composition frame rate controls the comp, not the source interpretation. Time Stretch changes playback speed as an editable property.

Question 41Importing, organizing, and managing assets

Which setting corrects a footage item that looks horizontally squeezed because it uses a non-square pixel aspect ratio?

  1. Set the footage's pixel aspect ratio Correct answer.
  2. Change the footage's alpha interpretation
  3. Scale the layer non-uniformly
  4. Set the composition's pixel aspect ratio

Explanation

Interpret Footage > Main > Pixel Aspect Ratio tells After Effects the shape of the source pixels so it can display the footage correctly. The composition's pixel aspect ratio should be set to match the intended output. Scaling can mask the problem but does not correct the source interpretation.

Question 42Importing, organizing, and managing assets

Which Interpret Footage setting should you use for interlaced footage that will be seen on a progressive display?

  1. Main > Assume This Frame Rate
  2. Alpha > Premultiplied
  3. Color Management > Preserve RGB Values option
  4. Fields and Pulldown > Separate Fields Correct answer.

Explanation

Separate Fields in Interpret Footage > Fields and Pulldown splits interlaced frames into individual fields so they can be processed or converted for progressive output. You also specify upper or lower field order. Changing frame rate or alpha interpretation does not remove interlacing.

Question 43Importing, organizing, and managing assets

You need to lay out a comp before final artwork arrives. Which feature creates a temporary footage item that can be replaced later?

  1. File > Import > Solid
  2. Layer > New > Adjustment Layer
  3. File > Import > Placeholder Correct answer.
  4. Composition > New Composition

Explanation

File > Import > Placeholder creates a temporary footage item with dimensions and duration you specify, so you can build a composition before the real media arrives. Later, Replace Footage > File swaps in the actual file while keeping edits. Adjustment layers and solids are generated inside a composition, not placeholder footage.

Question 44Importing, organizing, and managing assets

Which statement describes an Adobe Dynamic Link composition imported into After Effects?

  1. It remains linked to its source project Correct answer.
  2. It is rendered to a movie file on import
  3. It is converted into a placeholder item
  4. It becomes a set of merged video layers

Explanation

A Dynamic Link composition remains connected to its source Premiere Pro or Media Encoder project, so changes made there appear without an intermediate render. It is not flattened or converted to a placeholder. This avoids duplicate media and rendering steps.

Question 45Importing, organizing, and managing assets

A large project contains many unused footage items. Which command removes them from the project?

  1. Edit > Purge > Image Cache
  2. File > Dependencies > Reduce Project Correct answer.
  3. File > Save a Copy As
  4. File > Dependencies > Collect Files command

Explanation

Reduce Project removes footage items and compositions that are not used by the selected compositions, which shrinks the project. Collect Files gathers dependencies into a folder but does not remove unused items. Purging caches affects memory, not project items.

Question 46Importing, organizing, and managing assets

How can you quickly locate footage named 'logo' in the Project panel without scrolling?

  1. Switch the Project panel from Icon to List view
  2. Type logo in the Project panel search box Correct answer.
  3. Use the search field in the Timeline panel
  4. Choose Layer > Find

Explanation

The Project panel's search box filters the items shown by name and other columns, making it easy to find footage without scrolling. Timeline search operates on layers within a composition. Changing the panel view does not filter the list.

Question 47Importing, organizing, and managing assets

What is the purpose of color labels on Project panel items?

  1. They visually identify and group items Correct answer.
  2. They set the output color space
  3. They compress the footage file
  4. They lock the footage item against changes

Explanation

Color labels are organizational tags that help you identify and group items in the Project panel, and you can sort or select by label. They do not change color management, lock items, or compress files. Labels are only metadata for the project.

Question 48Importing, organizing, and managing assets

How do you display the Media Duration column in the Project panel?

  1. Press the tilde key repeatedly to maximize and restore the panel
  2. Choose View > Show Layer Controls
  3. Choose File > Project Settings > Duration
  4. Right-click a header, choose Columns > Media Duration Correct answer.

Explanation

Project panel columns can be customized by right-clicking a column header and choosing Columns, then toggling the desired metadata such as Media Duration. This does not affect the media itself. The tilde key maximizes the panel but does not add columns.

Question 49Importing, organizing, and managing assets

An Illustrator file is imported as a composition. Which option keeps each layer's original artboard-relative size rather than the composition size?

  1. Retain Layer Sizes Correct answer.
  2. Create Proxy
  3. Import As Footage (flattened)
  4. Merge Layers

Explanation

Retain Layer Sizes makes each imported Illustrator layer's footage item match the layer's artwork size and position instead of cropping it to the composition. Import As Footage flattens the artwork into one item. Create Proxy is a separate workflow for alternate media.

Question 50Importing, organizing, and managing assets

When importing a Cinema DNG sequence, which setting is required for After Effects to treat the frames as one footage item?

  1. Enable the sequence option for numbered files Correct answer.
  2. Enable Merge Layers in the import dialog
  3. Set the comp's frame rate before importing
  4. Choose Alpha > Straight in the Interpret Footage dialog

Explanation

Cinema DNG frames are still images, so the numbered files must be imported with the image sequence option enabled to form a single footage item. Otherwise each DNG frame imports separately. Alpha and frame-rate interpretation are set after import.
