|

While recent generative models advance pixel-space video synthesis, they remain limited in
|
||
producing
|
||
professional ecu videos, which demand disciplinary knowledge, precise visual structures, and
|
||
coherent transitions, limiting their applicabilityl in educational scenarios. Intuitively, such
|
||
requirements are better addressed through the manipulation of a renderable environment, which
|
||
can be
|
||
explicitly controlled via logical commands (<i>e.g., code</i>). In this work, we propose
|
||
<b>Code2Video</b>, a
|
||
codecentric agent framework for generating educational videos via executable Python code. The
|
||
framework
|
||
comprises three collaborative agents: <i>(i) Planner</i>, which structures lecture content into
|
||
temporally
|
||
coherent flows and prepares corresponding visual assets; <i>(ii) Coder</i>, which converts
|
||
structured
|
||
instructions into executable Python codes while incorporating scope-guided auto-fix to enhance
|
||
efficiency; and <i>(iii) Critic</i>, which leverages vision-language models (VLM) with anchor
|
||
visual
|
||
prompts to refine spatial layout and ensure clarity. To support systemati evaluation, we build
|
||
<b>MMMC</b>,
|
||
a benchmark of professionally produced, long-form, disciplinespecific educational videos. We
|
||
evaluate
|
||
MMMC across diverse dimensions, including VLM-as-a-Judge aesthetic scores, code efficiency, and
|
||
particularly, <b>TeachQuiz</b>, a novel end-to-end knowledge transfer measured by a VLM's
|
||
ability to
|
||
learn
|
||
from the generated videos. Our results demonstrate the potential of Code2Video as a scalable,
|
||
interpretable, and controllable approach for educational video generation.

<b>Illustration of Code2Video.</b> Given a user inquiry, Code2Video aims to render an
|
||
educational
|
||
video
|
||
via Manim code writing: (i) the Planner converts a learning topic into a storyboard and
|
||
retrieves
|
||
visual assets; (ii) the Coder performs parallel code synthesis with scope-guided refinement to
|
||
ensure efficiency and temporal consistency; (iii) the Critic uses anchor visual prompts to
|
||
iteratively adjust spatial layout and clarity, yielding reproducible, pedagogically structured
|
||
videos.
