12th tutorial - compressed DMD - function doesn't return noisy video after adding noise

[Luka Karlić]

Describe the bug
In the 12th tutorial - compressed DMD - there's an option to add the noise to the original video.
However, the function returns a video without noise (even if you added it).

Original method:

def get_video_dmd(
    object: str = "frog", noise: bool = False, noise_amt: float = 0.01
) -> Tuple[np.ndarray, Tuple[int, int]]:

...
 vid = np.vstack(imgs).T
    if noise:
        vid += np.random.normal(0, noise_amt, vid.shape)
        vid = vid.clip(0, 1)
    return np.vstack(imgs).T, shape

Return statement gives np.vstack(imgs).T, while it should be only vid
