    Bonus Tips
    To brighten a video without losing quality, don’t simply bump up the brightness or exposure because as you increase the brightness of a video, the video’s contrast and saturation and the details of the highlights of the video will go the opposite way. As a result, you will end up with a grey and wash-out video.
    The correct way to make a dark video brighter is by balancing the video brightness and its darkness. So, as you brighten the video, you also need to lower the contrast and highlights or even adjust the saturation to avoid overexposure and wash-out effect.
