If cropping is used, it is recommended to crop to pixel boundary positions divisible by 16 
to align on macroblock boundaries of the compressed video stream.  This provides the 
best video quality during cropping. 

If the input signal is cropped and the output resolution setting is different, then the video 
will be cropped and then scaled to the requested output resolution setting.  Therefore, 
you do not need to crop to an exact output resolution, the correct scaling will be applied. 

 

The Top and Bottom Parameters are in pixel units measured from the top of the 
incoming Frame. 

The Left and Right Parameters are in pixel units measured from the left of the incoming 
Frame. 

 

Cropping Example

Desired Output SD 720x480 frame, from upper left section of input Frame
