After Effects Text Masterclass

Expression Automation, Text Animators, and MOGRT Workflows

Text in After Effects is not just typing and fading. In professional motion graphics, it is a data-reactive object and the foundation of kinetic typography. This guide delivers the complete expert workflow from expression automation to MOGRT template monetization.



Usage ScenarioRisk LevelSafe Solution
“Free for Personal Use” font on monetized YouTube content🔴 Commercial use — severe penaltiesNever use without explicit commercial clearance
OFL (Open Font License) fonts✅ Commercially safeGoogle Noto Sans, Spoqa Han Sans, Nanum Square
Corporate/Municipal public fonts✅ VerifiedDouble-check distribution terms for commercial scope

The Forbidden Buttons — Faux Bold / Faux Italic

Never press the Faux Bold or Faux Italic toggles in the Character Panel. These distort the font designer’s carefully engineered geometric balance, permanently destroying readability. Always select the correct font Weight family (Thin, Regular, Medium, Bold, Black).

The Golden Ratios for Readability

PropertyDefaultProfessional SettingEffect
Horizontal Scale100%95–97%Denser, tighter, more premium character appearance
Tracking0Slightly tightenedWords read as unified visual groups
KerningAutoManual Alt + ←/→Perfect visual balance between specific letter pairs

💡 The Readability Test: “Can a first-time viewer read this instantly?” — not “Can I read it?” Always maintain a minimum 8–10 frame hold after an animation ends before the text leaves screen.


Part 2: Expression Automation — The Studio Advantage

① CSV/JSON Data-Driven Pipelines

Import a CSV or JSON file into After Effects → link sourceData to the text layer’s Source Text via expression → update the external Excel/JSON file to update all text instances across the entire project simultaneously.

→ 100 name tags or lower-thirds updated without ever reopening After Effects.

② Comma-Separated Number Counter

Animating rising financial values, statistics, or scores:

// Apply to Source Text — link to a Slider Control effect
num = Math.floor(effect("Slider Control")("Slider"));
num.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");

Keyframe only the Slider value — the expression automatically formats 1,234,567 with perfect thousands separators.

③ Terminal Typing Effect with Blinking Cursor

Far superior to the native Typewriter preset:

L = thisLayer.sourceText.length;
T = time * 10;           // Adjust '10' to change typing speed
F = Math.round(time % 1); // Calculates blink cycle
cursor = F == 1 ? "|" : "";
value.substr(0, T) + cursor;

→ Text reveals character by character with a blinking | cursor that pulses every second — authentic terminal/coding aesthetic.


Part 3: Text Animators — Procedural Motion Without Keyframes

Open any text layer → click Animate → animate individual characters, words, or lines independently.

Wiggly Selector — Liquid Motion

Correlation ValueBehaviorVisual Result

50–80%Letters influence each other’s movementOrganic wave, liquid, or flocking-flock behavior

💡 Advanced stacking: Add Position + Rotation + Character Offset + Blur into one Animator group → randomized letters blur and snap into place to reveal the final word — the “decoding” effect used in high-end broadcast titles.


Part 4: Path Text Options

Flow text along curves, circles, or custom paths:

  1. Select text layer → draw path with Pen Tool → set Mask Mode to “None”
  2. Layer → Text > Path Options > Path → assign the mask

Path Parameter Reference

ParameterFunctionNote
First MarginPosition of text along path — keyframe to animate flowNews tickers, scrolling marquees
Reverse PathFlips text directionControl inside vs. outside of circular paths
Perpendicular to PathOn = letters tilt with curve / Off = letters stay uprightDesign-dependent choice
Force Alignment⚠️ Destroys kerning — avoidForces text to stretch across entire path length

Part 5: MOGRTs for Collaboration and Revenue

① Responsive Auto-Sizing Background Box

A background that automatically grows and shrinks with text length:

// Apply to Shape Layer Size property
txt = thisComp.layer("SubtitleText");
w = txt.sourceRectAtTime().width;
h = txt.sourceRectAtTime().height;
[w + 50, h + 30]  // 50 and 30 = left/right and top/bottom padding

No matter what text the editor types, the background box tracks it perfectly.

② Protected Regions — Preserving Animation Timing

When Premiere editors stretch the clip duration, intro/outro animations must not slow down:

Set opening and closing animation sections as Protected Regions → only the middle hold time stretches → all motion timing is perfectly preserved at the original speed.

③ Empowering Editors with Font Freedom

Essential Graphics panel → drag Source Text property → right-click → check “Allow Font Selection” → Premiere users can change fonts freely without returning to After Effects.
