Animated Film Grain with Eevee
If you ever tried to do film grain in the compositor you may have hit a wall when animating, since the “old” noise textures are pretty basic. There’s a better way! We can use the new noises to simulate film grain, dust and other imperfections directly with Eevee.
Note that you can also use the Generator Modifier instead of noise for the animation and you can also add a math noise to offset the W coordinate of the second noise.
