Adding Noise in After Effects

Adding a small amount noise before converting media to any codec is a good way to reduce compression artifacts.

The easiest way is to use the noise effect in After Effects.

Example

1. Create a new After Effects project and composition, and add your content as a layer.

2. Next, select your content layer. and from the toolbar choose Effect > Noise & Grain > Noise.
   Or apply a preset to your content by clicking here and importing it into the After Effects composition.

3. Now in the effects property box, set the amount of noise to be applied.
   Settings the noise to 2 - 3% works well.

4. Now you can render out your content.
