nnedi2 is an intra-field only deinterlacer. It takes in a frame, throws away one field, and then interpolates the missing pixels using only information from the kept field; it has same rate and double rate modes.
nnedi2 is also very good for enlarging images by powers of 2, and includes a function 'nnedi2_rpow2' for that purpose.

  • nnedi3 is strongly recommended.
