Production Quality

Production Quality Standards

3Blue1Brown-style standards for professional mathematical animations.

Color Standards

Semantic Color Palette

Limit to 5 semantic colors per video:

COLORS = {
    "PRIMARY": BLUE,        # Main concept
    "SECONDARY": ORANGE,    # Supporting/contrasting concept
    "POSITIVE": GREEN,      # Success, correct, good
    "EMPHASIS": PURPLE,     # Highlights, key insights
    "MUTED": GRAY,          # De-emphasized, background
}

Color Guidelines

Avoid

• More than 5 distinct colors
• RED for general highlighting (reserve for errors/warnings)
• Similar shades that are hard to distinguish
• Colors that don't contrast with black background

Timing Standards

Animation Durations

Wait Times

Timing Constants

TIMING = {
    # Animation durations
    "FAST": 0.5,
    "NORMAL": 1.0,
    "SLOW": 2.0,
    "DRAMATIC": 3.0,

    # Wait times
    "BRIEF": 0.5,
    "STANDARD": 1.0,
    "EXTENDED": 2.0,
    "COMPLEX": 4.0,
    "CRITICAL": 6.0,
}

Anti-Patterns

# TOO FAST - viewer can't process
self.play(Write(formula), run_time=0.3)

# NO BREATHING ROOM
self.play(anim1)
self.play(anim2)
self.play(anim3)

# GOOD - appropriate pacing
self.play(Write(formula), run_time=2)
self.wait(4)  # Time to understand
self.play(next_animation)

Positioning Standards

Never Use Magic Numbers

# BAD - Magic numbers
element.shift(LEFT * 3.5)
title.move_to([2, 3, 0])
box.scale(0.73)

# GOOD - Relative positioning
element.move_to(LEFT * config.frame_width / 4)
title.to_edge(UP, buff=0.5)
box.scale_to_fit_width(axes.width * 0.3)

Positioning Methods

# Relative to screen
obj.to_edge(UP, buff=0.5)
obj.to_corner(UR)
obj.move_to(ORIGIN)

# Relative to frame
obj.move_to(LEFT * config.frame_width / 4)
obj.move_to(UP * config.frame_height / 3)

# Relative to objects
obj.next_to(other, RIGHT, buff=1.0)
obj.align_to(other, UP)

# Group arrangement
VGroup(a, b, c).arrange(DOWN, buff=0.5)
VGroup(a, b, c).arrange_in_grid(rows=2)

Standard Buffers

Scene Organization

One Concept Per Scene

Each scene should convey ONE main idea:

# BAD - Multiple concepts
class OverloadedScene(Scene):
    def construct(self):
        # Concept 1: Definition
        # Concept 2: Properties
        # Concept 3: Examples
        # Concept 4: Proofs

# GOOD - Focused scenes
class DefinitionScene(Scene): ...
class PropertiesScene(Scene): ...
class ExampleScene(Scene): ...
class ProofScene(Scene): ...

Section Organization

class WellOrganizedScene(Scene):
    def construct(self):
        self.next_section("Introduction")
        self.show_title()

        self.next_section("Main Concept")
        self.show_visualization()

        self.next_section("Key Insight")
        self.show_insight()

        self.next_section("Conclusion")
        self.show_summary()

    def show_title(self):
        """Isolated logic for title"""
        pass

    def show_visualization(self):
        """Isolated logic for main content"""
        pass

Object Tracking

Track Everything

class ProductionScene(Scene):
    def setup(self):
        self.tracked = []

    def track(self, *mobjects):
        """Add mobjects to tracking and scene"""
        for m in mobjects:
            self.tracked.append(m)
            self.add(m)
        return mobjects[0] if len(mobjects) == 1 else mobjects

    def cleanup(self, keep=None):
        """Fade out tracked objects except those in keep"""
        keep = keep or []
        to_remove = [m for m in self.tracked if m not in keep]
        if to_remove:
            self.play(*[FadeOut(m) for m in to_remove])
        self.tracked = list(keep)

Avoid Nuclear Cleanup

# BAD - Destroys everything blindly
self.play(FadeOut(*self.mobjects))

# GOOD - Explicit control
self.cleanup(keep=[title, axes])

Typography Standards

Font Size Scale

FONTS = {
    "TITLE": 52,      # Scene titles
    "SECTION": 42,    # Section headers
    "BODY": 28,       # Body text
    "SMALL": 24,      # Annotations
    "FORMULA": 38,    # Standalone formulas
}

Text Guidelines

• Use consistent font sizes
• Limit text on screen (prefer visuals)
• Use Text() for prose, MathTex() for math
• Avoid orphaned words (single word on line)

Visual Hierarchy

Primary → Secondary → Tertiary

# Primary focus: Large, bright, centered
main_concept = ...
main_concept.scale(1.2).set_color(COLORS["PRIMARY"])

# Secondary: Normal size, slightly dimmer
support = ...
support.set_color(COLORS["SECONDARY"])

# Tertiary: Smaller, muted
background = ...
background.scale(0.8).set_color(COLORS["MUTED"])

Attention Management

# Dim old content when showing new
old_content.animate.set_opacity(0.3)

# Highlight current focus
current.animate.set_color(COLORS["EMPHASIS"])

# Use movement to guide eye
new_element.animate.shift(target_position)

Quality Checklist

Before rendering, verify:

Colors

• Maximum 5 semantic colors
• Each color has consistent meaning
• All colors visible on black background

Timing

• No animations under 0.5s
• Wait after complex content
• Pacing matches content complexity

Positioning

• No magic numbers
• All positions relative
• Consistent spacing/buffers

Organization

• One concept per scene
• Sections marked with next_section()
• Objects tracked for cleanup

Typography

• Consistent font sizes
• Minimal on-screen text
• Formulas properly formatted

Production Workflow

1. Planning

• Define ONE concept for scene
• Plan timeline with durations
• Identify color assignments

2. Implementation

• Use config constants
• Track all objects
• Use helper methods

3. Review

• Run quality checklist
• Preview at low quality
• Check timing feels natural

4. Polish

• Fine-tune timing
• Adjust colors for clarity
• Ensure smooth transitions

5. Export

• Render at target quality
• Verify output plays correctly
• Check file size is reasonable
