I know how to iterate over an image, finding the color of each pixel, and modifying it. Is there’s an easier method to adjust the brightness of a video, namely so that it doesn’t cause the video to lag?

You could also use `tint()` – or use `blendMode()` when drawing the video over a white background. Either can achieve a brightening effect on an image or video frame.

I am not sure how these approaches perform compared to iterating over pixels[] – but try them and see.
