Examples

Example: UseZoomedScene

from manim import *

class UseZoomedScene(ZoomedScene):
    def construct(self):
        dot = Dot().set_color(GREEN)
        self.add(dot)
        self.wait(1)
        self.activate_zooming(animate=False)
        self.wait(1)
        self.play(dot.animate.shift(LEFT))

Example: ChangingZoomScale

from manim import *

class ChangingZoomScale(ZoomedScene):
    def __init__(self, **kwargs):
        ZoomedScene.__init__(
            self,
            zoom_factor=0.3,
            zoomed_display_height=1,
            zoomed_display_width=3,
            image_frame_stroke_width=20,
            zoomed_camera_config={
                "default_frame_stroke_width": 3,
            },
            **kwargs
        )

    def construct(self):
        dot = Dot().set_color(GREEN)
        sq = Circle(fill_opacity=1, radius=0.2).next_to(dot, RIGHT)
        self.add(dot, sq)
        self.wait(1)
        self.activate_zooming(animate=False)
        self.wait(1)
        self.play(dot.animate.shift(LEFT * 0.3))

        self.play(self.zoomed_camera.frame.animate.scale(4))
        self.play(self.zoomed_camera.frame.animate.shift(0.5 * DOWN))
