**Radial Distortion 1**  
Quadratic radial lens distortion coefficient. Positive values produce pincushion distortion. Negative values produce barrel distortion.  



  
**Radial Distortion 2**  
Quartic radial lens distortion coefficient. Positive values produce pincushion distortion. Negative values produce barrel distortion.




**Asymmetric Distortion X**  
Distortion applied only in the X direction. Horizontal lines will remain straight. Positive values produce pincushion-like distortion. Negative values produce barrel-like distortion.




**Asymmetric Distortion Y**  
Distortion applied only in the Y direction. Vertical lines will remain straight. Positive values produce pincushion-like distortion. Negative values produce barrel-like distortion.




**Anamorphic Squeeze**

Anamorphic lens squeeze. Values greater than one decrease the effect of the lens distortion in the X direction. Values less than one increase it.

The image above has an** **Asymmetric Distortion X value of 0.3 and an anamorphic squeeze value of 1



And above, these images have an anamorphic squeeze value of 0.5 and 1.5
