Conversion Quality

Set the conversion quality for format conversions. Lower quality means more speed. Values above 3 enable slow high quality calculations.

sm=<string>

Supported strings: auto nearest bilinear quadratic cubic_bspline cubic_mitchell cubic_catmull sinc_lanczos

Default: auto

Scale mode

Choose scaling method. Auto means to choose based on the conversion quality. Nearest is fastest, Sinc with Lanczos window is slowest.

so=<number> (4..1000, default: 4)

Scale order

Order for sinc scaling

dm=<string>

Supported strings: none copy scale

Default: none

Deinterlace mode

Specify interlace mode. Higher modes are better but slower.

ddm=<string>

Supported strings: top bottom

Default: top

Drop mode

Specifies which field the deinterlacer should drop.

fd=[1|0] (default: 0)

Force deinterlacing

Force deinterlacing if you want progressive output and the input format pretends to be progressive also.
