 ==Notes to Mathematicians: (and questions)==
 Imagine the screen was dimensions that went from -1.0 to 1.0. We'll only consider the horizontal dimension for the moment and only the right hand half of the screen. Assume we want to calculate the value of an output pixel at location x, where 0 <= x <=1.

 *{{Template:FuncDef3|InterlacedResize}} and {{Template:FuncDef3|InterlacedWarpedResize}} work like <tt>SimpleResize</tt> and <tt>WarpedResize</tt> but are designed to operate on interlaced source, without either blending even/odd data or messing up the coordinates because of the even/odd line offsets. Theoretically these can lose a small amount of vertical detail or confuse a subsequent deinterlace or IVTC function but so far in my own testing I have not found it to be a problem.  So if you intend to keep your video in interlaced form, certainly use these.  And if you are downsizing you may find that doing the <tt>InterlacedResize</tt> first before a more costly deinterlacing step can give you a small performance advantage on other material. But this is still experimental. YMMV.
