Apply motion-compensation deinterlacing.
It needs one field per frame as input and must thus be used together with yadif=1/3 or equivalent.
This filter accepts the following options:
- mode
 - 
               
Set the deinterlacing mode.
It accepts one of the following values:
- fast, medium, slow
 - 
                     
use iterative motion estimation
 - extra_slow
 - 
                     
like slow, but use multiple reference frames.
 
Default value is fast.
 - parity
 - 
               
Set the picture field parity assumed for the input video. It must be one of the following values:
- 0, tff
 - 
                     
assume top field first
 - 1, bff
 - 
                     
assume bottom field first
 
Default value is bff.
 - qp
 - 
               
Set per-block quantization parameter (QP) used by the internal encoder.
Higher values should result in a smoother motion vector field but less optimal individual vectors. Default value is 1.
