A damaged film reel footage, with original projector sound included, good for altering your video, for producing the reel film look, or as background/credits video. The video is full of camera jitter and flicker, and wear, spots and scratches and is designed to be used in After Effects, as overlay video, blended in multiply style, over your main video. (Recommended method, but the are also other ways of use.)
For ex. you may just put it over your layer video, in AfterEffects, use Blending Style, like Multiply, and have the damage effect altering directly your video.
