I don't think it's only that, but it's probably only slightly longer
to implement.

For interlaced 4:2:0, each chroma field has a phase shift,
respectively 3/4 and 1/4. If I'm not mistaken, you can probably run
each filter on each field, and that's it. Though it's probably better
to unroll it for the 2 fields.

Or I could read the fine code.
