Thanks

No, it's motion estimation accuracy

pel : it is the accuracy of the motion estimation. Value can only be 1, 2 or 4. 1 means a precision to the pixel. 2 means a precision to half a pixel, 4 means a precision to quarter a pixel, produced by spatial interpolation (more accurate but slower and not always better due to big level scale step). Default is 2 since v1.4.10.
