Flashing in still image
Hello all, I am looking for an explanation or link to any other resources that will educate me on achieving a still image with a flickering background. Instead of trying to explain this through text, I have supplied an example here : Big Sean / Jhene Aiko / Key Wane Type Beat - 2016 (Prod. Alex Collins) - YouTube I have seen various patterns and styles (exp: one image/video appeared to have a background that appeared to be snowing) but they all basically the same style/idea. If this has been address elsewhere, i apologize, but any help is greatly appreciated.
