manimce-best-practices

Trigger when: (1) User mentions "manim" or "Manim Community" or "ManimCE", (2) Code contains `from manim import *`, (3) User runs `manim` CLI commands, (4) Working with Scene, MathTex, Create(), or ManimCE-specific classes. Best practices for Manim Community Edition - the community-maintained Python animation engine. Covers Scene structure, animations, LaTeX/MathTex, 3D with ThreeDScene, camera control, styling, and CLI usage. NOT for ManimGL/3b1b version (which uses `manimlib` imports and `manimgl` CLI).

Quick Reference

Basic Scene Structure

from manim import *

class MyScene(Scene):
    def construct(self):
        # Create mobjects
        circle = Circle()

        # Add to scene (static)
        self.add(circle)

        # Or animate
        self.play(Create(circle))

        # Wait
        self.wait(1)

Render Command

# Basic render with preview
manim -pql scene.py MyScene

# Quality flags: -ql (low), -qm (medium), -qh (high), -qk (4k)
manim -pqh scene.py MyScene

Key Differences from 3b1b/ManimGL

Feature	Manim Community	3b1b/ManimGL
Import	`from manim import *`	`from manimlib import *`
CLI	`manim`	`manimgl`
Math text	`MathTex(r"\pi")`	`Tex(R"\pi")`
Scene	`Scene`	`InteractiveScene`
Package	`manim` (PyPI)	`manimgl` (PyPI)

Jupyter Notebook Support

Use the %%manim cell magic:

%%manim -qm MyScene
class MyScene(Scene):
    def construct(self):
        self.play(Create(Circle()))

Common Pitfalls to Avoid

Version confusion - Ensure you're using manim (Community), not manimgl (3b1b version)
Check imports - from manim import * is ManimCE; from manimlib import * is ManimGL
Outdated tutorials - Video tutorials may be outdated; prefer official documentation
manimpango issues - If text rendering fails, check manimpango installation requirements
PATH issues (Windows) - If manim command not found, use python -m manim or check PATH

Installation

# Install Manim Community
pip install manim

# Check installation
manim checkhealth

Useful Commands

manim -pql scene.py Scene    # Preview low quality (development)
