Summary

Generate publication-grade ML explainer videos and carousels the way 3Blue1Brown actually builds them — in real manimGL (NOT Manim Community Edition), as a tiny domain DSL of self-arranging Mobjects choreographed into transform-driven beats where every motion carries meaning. Ove

So: nothing — not even slightly — may be wrong. Every spoken line, every on-screen number and label, every caption, and the thumbnail must be verified against the primary source before it is rendered, and audited again on the rendered video before it ships (§10, the non-negotiable gate). If you cannot cite the exact source line for a claim, you do not say it, write it, or put it on screen. Soften it or cut it. No "dramatic license" on numbers. When in doubt, it is wrong until proven right.
7
8	This skill was rebuilt from a full read of Grant Sanderson's actual production code (`github.com/3b1b/videos`, 503K LOC, 2015→2026) and the real manimGL engine (`github.com/3b1b/manim`). Every rule below is grounded in that source with `file:line` citations. Where this skill once guessed, it now measures.
9
10	The video engine is manimGL (the 3b1b version), driven by `manimgl`. Manim Community Edition (CE) is a different library with a different, incompatible API — code written for one crashes on the other. Static IG carousels use HTML/matplotlib (see the Carousel section); everything animated is manimGL.

14	## 0. Why the old output was slop (read this once)
15
16	The previous version of this skill produced overlapping elements, weak animation, no consistency, and infographic-feeling stills. The root causes, now fixed:
17
18	1. It shipped Manim CE code while preaching manimGL. The old template used `from manim import `, `MathTex`, `ThreeDScene`, `set_camera_orientation`, `set_fill_by_value`, `Create`, `begin_ambient_camera_rotation` — none of which exist in manimGL* (`grep` over the entire engine = 0 hits). It would not even run.
19	2. 100% of real output was actually built in matplotlib, hand-placing ~57 text calls + ~20 boxes per scene with absolute coordinates. That is the worst possible tool for animation: no relative layout, no transform system, no camera. Overlap is guaranteed.
20	3. It treated overlap as a validation problem (bbox asserts, frame validators, ffmpeg caption-pads) instead of a construction problem. 3b1b never validates overlap — it makes overlap structurally impossible by building self-arranging objects.
21	4. It treated motion as decoration. Elements faded in from nowhere as disconnected islands. In real 3b1b, objects are born from the thing they abstract (`TransformFromCopy`), so every motion teaches.
22	5. Planning was marketing copy with word-count targets. Real 3b1b planning is an ordered list of named teaching beats that reads top-to-bottom as the narration.
23
24	The fix is a different mental model, encoded as the Six Laws below.

28	## 1. The engine reality (the single most important section)
29
30	Start every manim file with:
31	```python
32	from manim_imports_ext import * # in the 3b1b/videos repo
33	# or, standalone: from manimlib import *
34	```
35
36	Scene base class is `InteractiveScene` (`interactive_scene.py:66`) — for 2D and 3D. In the entire 2025 corpus: `InteractiveScene` subclassed 385 times, `ThreeDScene` (`scene.py:930`) 0 times — it exists but 3b1b never uses it. 3D is achieved on an `InteractiveScene` by moving `self.frame`.
37
38	The camera is `self.frame` (a `CameraFrame` mobject; `scene.py:112`). Local alias `frame = self.frame` appears 114× in 2025 code. `self.camera.frame` appears 0×.
39
40	Render / iterate:
41	```bash
42	manimgl file.py SceneName # render
43	manimgl file.py SceneName -se 120 # drop into IPython at line 120 (the dev loop)
44	manimgl file.py SceneName -w # write to file
45	# inside the embed: checkpoint_paste() runs clipboard code with checkpoint rewind
46	```
