Getting 'Couldn't find ffmpeg or avconv' message despite having installed both?

[aflockdescends]

Hello, I hope this is the right place to post. I'm trying to get started with Manim and am having trouble with the set up. I am running Python 3.9 on macOS Catalina (10.15.7)

• I installed ffmpeg via "brew install ffmpeg" in Terminal, and also installed libav with "brew install libav". When I put "ffmpeg" or "avconv" in Terminal, all appears to be fine.
• I installed manim via "pip3 install manim". Again, seems to be fine upon check. I also did manimgl.

I managed to locate ffmpeg, it is in /usr/local/Cellar. I don't know whether that is where it's meant to be or not. Anyway, I opened up Python using IDLE, and pasted the following 'test' code:

from manim import *

class SquareToCircle(Scene):
def construct(self):
circle = Circle()
circle.set_fill(PINK, opacity=0.5)
self.play(Create(circle))

I then get the following error message:

Warning (from warnings module):
File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/pydub/utils.py", line 170
warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)
RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work

I'm not terribly experienced so I'm having trouble diagnosing the problem and would really appreciate some help! :)
