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:
         
         
            - 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.
                  
 
- 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.
                  
 
- When you are satisfied with the result,
               click Process to add grain to the clip.
