# manim Manim (Manim Community edition) renders animations from Python: a `Scene` subclass whose `construct()` plays animations on mobjects. The render lands as MP4 under `out/`. Tools: `$MANIM` (the pinned CLI), `$MANIM_PYTHON` (its interpreter). Never install another. ## Render (the verdict comes with it) ```bash "$MANIM_PYTHON" "$MANIM_TOOLCHAIN/render.py" scenes/intro.py Intro # quick: 480p15, the default "$MANIM_PYTHON" "$MANIM_TOOLCHAIN/render.py" -qm scenes/intro.py Intro # medium: 720p30 "$MANIM_PYTHON" "$MANIM_TOOLCHAIN/render.py" -qh scenes/intro.py Intro # final: 1080p60 "$MANIM_PYTHON" "$MANIM_TOOLCHAIN/render.py" --format gif scenes/x.py Name # a gif instead ``` `render.py` is `manim render` with the same flags, output and tracebacks, plus what the pane needs: `--media_dir out --save_sections`, a live progress file (the pane plays each animation as it is written and shows a failure with its line), a record of the render's animations and chapters, and the verdict at the end. Use it for every render; plain `$MANIM render` still works but the pane sees less. Renders go to `out/videos/<file>/<quality>/<Scene>.mp4`. Render at `-ql` while iterating (fast), `-qh` once at the end. ## Chapters The pane shows a scene's sections as chapters — on the timeline, in a list, as `1`…`9` keys. Mark every beat of the storyboard with a section, named the way a chapter title reads: ```python def construct(self): self.next_section("The question")...
