You should choose the right deinterlacer based on the quality of the output needed.
The simple Bob deinterlacing option produces the lowest quality outputs; and the motion adaptive high

quality (HQ) option produces the highest quality outputs.

Figure B-1: Bob Deinterlacing Option

The figure below shows an example output from Bob deinterlacing option.

To enable this option, select Bob Scanline Interpolation in the Deinterlacer IP core parameter editor.

With this moving Dial test sequence, a Bob deinterlacer produces the characteristic staircasing effect on

the edges of these diagonal lines. The area is 454 look-up tables (LUTs).
