Create professional effects with After Effects: Realize creative ideas

After Effects has long been an indispensable tool in the film post-production industry. Not only does it create visual effects, this software also helps realize bold ideas and expand storytelling capabilities in cinema. Thanks to its powerful effects processing capabilities, AE becomes an ideal companion for those who want to explore the world of professional effects. Let's find out more details with sadesign in the content below!

1. What is After Effects and why is it chosen for film special effects?

After Effects is a motion graphics and video effects software developed by Adobe, featuring the ability to create effects, animate, compositing and process dynamic images. In the film industry, AE is often used for scenes that require sophisticated post-processing, such as changing backgrounds, creating simulated environments, creating explosion effects, embedding 3D images or smoothing camera movements.

Not only limited to the film industry, AE is also a popular tool in the production of advertisements, MVs, TVCs, trailers and other interactive media formats. What makes AE attractive is its flexibility in application, the ability to combine with other software such as Premiere Pro, Cinema 4D, Photoshop and Illustrator.

The role of AE in video production is extremely important. It is not only used to create "magical" special effects but also used to:

Create Motion Graphics for intros, outros, titles, and UI/UX elements in videos.

Perform compositing: combine different shots, add CG (Computer Graphics) elements to real footage.

Edit and enhance images: adjust colors, remove blemishes, stabilize shaky images.

Create special effects: explosions, smoke, water, light, transformation, etc.

Keying: separates objects from the background (usually a green background or chroma key).

Tracking and Matchmoving: track the movement of objects in the video to attach graphic or 3D elements.

2. Types of cinematic effects that can be created with AE

Adobe After Effects (AE) is a powerful tool in film and video production, allowing for the creation of many types of professional cinematic effects. Some of the popular effects that can be achieved using AE include:

2.1. Compositing – Image overlay technique

Compositing is one of the outstanding strengths of AE. This technique allows combining multiple layers of images or videos together to create a complete scene. AE provides powerful tools such as masking, keying (chroma key/green screen), blending modes for users to easily process post-production with high precision.

Scenes that use green screens to change the setting are often finished using compositing techniques in AE.

2.2. Motion Tracking và Camera Tracking

Motion Tracking allows AE to track the movement of an object in a video and apply effects to it smoothly and accurately. Camera Tracking is more advanced, helping to simulate camera movement in 3D space. This is the foundation for inserting virtual objects or flying letters according to real camera angles, often seen in action and science fiction movies.

2.3. Fire, smoke, and explosion effects

After Effects allows for realistic explosions and destruction effects using plugins like Trapcode Particular, Video Copilot's Action Essentials, or built-in particle systems. This allows for scenes that would otherwise be impossible in real life, such as house fires, car explosions, or flying debris, to be safely shot digitally.

2.4. Light and energy effects

Cinematic effects cannot lack artificial light, energy rays, electromagnetic effects or force fields. AE provides many simulation tools such as Glow, Saber, Optical Flares to create extremely eye-catching cinematic effects. These types of effects are often used in superhero action scenes, science fiction or modern music videos.

2.5. Space and time simulation techniques

With tools like Time Remapping, Echo, Time Displacement, post-production workers can create fast-forward, slow-motion, looping effects or create illusions in space. AE also supports the creation of "space portals", "teleportation" or "freeze time" - effects that have been used a lot in blockbuster movies.

3. Important basic knowledge when doing special effects with AE 

3.1. Basic AE interface and workspace

Project Panel: Where you manage all your media files (video, images, audio), compositions and folders.

Composition Panel: Displays the contents of the Composition you are working on. This is the main "screen" for previewing the results.

Timeline Panel: Where you arrange layers in time, adjust properties, and add keyframes to create animations.

Effects & Presets Panel: Contains a list of effects available in AE and presets you can apply to layers.

Tools Panel: Provides tools for working with layers such as Selection Tool, Hand Tool, Zoom Tool, Rectangle Tool, Ellipse Tool, Pen Tool, Rotate Tool, Scale Tool, Camera Tool, etc.

Info Panel, Audio Panel, Preview Panel: Additional panels provide detailed information, audio controls, and performance preview.

Workspace: AE allows you to customize your workspace by arranging panels as you like and saving them into different workspaces for specific tasks (e.g. Standard, Animation, Effects).

3.2. Understanding Composition (Comp), Timeline and Layers

Composition (Comp): Comp is the "heart" of an AE project. It is where you assemble layers, apply effects, and create animations. Each AE project can contain many different Compositions. You need to set parameters for Comp such as Resolution, Frame Rate, Duration, and Aspect Ratio when creating a new one.

Timeline Panel: This is where you control the timing and display order of the layers in your Comp. Each layer will have its own timeline where you can add keyframes to animate the layer properties. The timeline also displays markers, effects, and other time-related information.

Layers: Layers are individual elements in a Composition. They can be video footage, still images, text, shape layers, solid colors, cameras, lights, or another Composition (Pre-comp). Layers are stacked

3.3. Basic properties of Layer

When you select a layer in the Timeline, you'll see its basic adjustable properties. These are the foundation for creating animations and transition effects:

Position (P): Determines the position of the layer in the Composition Panel in terms of X (horizontal) and Y (vertical) coordinates. You can change the position of the layer over time to create a moving effect.

Scale (S): Adjusts the size of the layer by a percentage both horizontally and vertically. You can make the layer enlarge or shrink over time.

Rotation (R): Rotate the layer around the Anchor Point in degrees. You can create a circular effect or more complex movements.

Opacity (T): Adjusts the layer's transparency, from 0% (fully transparent) to 100% (fully visible). Creates fade in, fade out effects, or makes layers invisible.

Anchor Point (A): The anchor point of the layer, which is the center that the transformations (Scale, Rotation) will be based on. By default, the Anchor Point is in the middle of the layer, but you can move it to create different rotation or масштабирование effects. For example, move the Anchor Point below an object to have it rotate around the bottom.

3.4. Keyframe and Animation: Creating Smooth Motion

Keyframe: A marker on the Timeline that marks the value of a layer property at a specific point in time. To create animation, you change the value of a property at different points in time and AE automatically creates in-between frames to create smooth motion.

Create Keyframe: To add a keyframe to an attribute, click the stopwatch icon next to the attribute name in the Timeline. A diamond-shaped keyframe marker will appear at the current time cursor position.

Adjust Animation: To change the animation, move the time cursor to a different location on the Timeline and change the property value. A new keyframe will be automatically added.

Easing: To make the animation look more natural and smooth, you can use easing. Easing adjusts the speed of change between keyframes. Common easing options include Easy Ease (F9), Easy Ease In (Shift + F9), and Easy Ease Out (Ctrl/Cmd + Shift + F9). You can also tweak the speed curve in the Graph Editor for more precise control.

3.5. Learn about Mask and Matte 

Mask: A path drawn on a layer that defines which areas of the layer will be visible and which will be hidden. Masks can be any shape (rectangle, circle, complex curve) and can be animated over time.

Matte: A layer used to define the transparency of another layer. Instead of painting the mask directly, you use the brightness or transparency of one layer as a "mold" for another layer.

3.6. Introduction to Blend Mode and Track Matte
Blend Mode: Determines how a layer interacts in color and brightness with the layers below it in the layer stack. AE offers a variety of blend modes, each of which creates a unique combined effect (e.g. Multiply, Screen, Add, Overlay, Difference). Experimenting with different blend modes is a great way to create interesting visual effects.

Track Matte: Similar to Matte, but applied directly in the Timeline Panel to a specific layer. You can select another layer as an Alpha Matte or Luma Matte for the current layer. Track Matte is a quick and efficient way to create complex masking effects without painting a mask directly on the target layer.

4. Plugins and tools to support effects in AE

4.1. Element 3D

This is a powerful plugin that supports 3D processing directly in AE. It allows users to import 3D models, assign materials, light, and animate without switching to other 3D software. Suitable for inserting machines, vehicles, weapons, or digital objects into the scene.

4.2. Trapcode Suite

A suite of plugins from Red Giant that help create particle, light, liquid, and optical illusion effects. Trapcode Particular and Form are two of the most powerful tools for creating fireworks, smoke, rain, or abstract special effects.

4.3. Optical Flares và Saber

5. Process of making cinematic effects with AE

5.1. Import

Users start by importing original footage from the camera, supporting assets (images, sounds, textures, 3D effects, etc.). Organizing layers and folders scientifically will help save time later.

5.2. Trim and standardize footage

Before starting to apply effects, the footage needs to be trimmed and standardized to ensure consistency in speed, frame rate, and resolution. Operations such as color correction or image stabilization are also performed during this stage.

5.3. Create effects using layers and effects

This is the most important stage. Each effect will be placed on one or more separate layers. The user uses keyframes to control the movement, transparency, position and other parameters to create the exact effect required.

5.4. Lighting, shadows, environment simulation

For scenes with 3D elements, proper lighting and shading settings are needed to create depth and sync with the real lighting in the original footage. AE supports virtual lights and virtual cameras for users to control the space.

5.5. Rendering

Once completed, the video is exported using Adobe Media Encoder or via AE’s own rendering system. Choosing the right format ensures optimal image quality when it enters the next stage of post-production or release.
