ImportError: DLL load failed: The specified module could not be found.

O erro ocorre ao importar cv2 (OpenCV) no Windows, provavelmente devido a dependências DLL ausentes. Verifique a instalação do OpenCV, assegure-se de que os Visual C++ redistributables estejam presentes e valide a variável de ambiente PATH. Verifique a cadeia de importação em big_ol_pile_of_manim_imports.py e scene_from_video.py. O teste consiste em executar o comando com falha após a resolução de dependências.
