# Adjusting the Grain Size

You can adjust the grain size if the grain match is not quite what you want. When you adjust the grain size, especially when trying to match grain, look at an area of intermediate brightness. The grain in dark areas sometimes appears larger than in bright areas because it is more difficult to distinguish between dark pixels.

To adjust the grain size:

1. To adjust the radius of the grain along the X-axis, drag the RGB X Radius sliders:
   - Enable Proportional and drag the RGB Gain sliders to add grain proportionately to the R, G, and B channels.
   - Disable Proportional and adjust the R, G, and B channels independently to fine-tune the grain radius.
2. To adjust the radius of the grain along the Y-axis, drag the RGB Y Radius sliders:
   - With Proportional enabled, drag the RGB Gain sliders to add grain proportionately to the R, G, and B channels.
   - Disable Proportional and then adjust the R, G, and B channels independently to fine-tune the grain radius.
3. When you are satisfied with the result, click Process to add grain to the clip.
