This filter accepts the following options:

method

Specify the motion estimation method. Accepts one of the following values:

‘esa’

Exhaustive search algorithm.

‘tss’

Three step search algorithm.

‘tdls’

Two dimensional logarithmic search algorithm.

‘ntss’

New three step search algorithm.

‘fss’

Four step search algorithm.

‘ds’

Diamond search algorithm.

‘hexbs’

Hexagon-based search algorithm.

‘epzs’

Enhanced predictive zonal search algorithm.

‘umh’

Uneven multi-hexagon search algorithm.

Default value is ‘esa’.

mb_size

Macroblock size. Default 16.

search_param

Search parameter. Default 7.
