A video camera (not a film camera) that records interlaced takes a capture each 1/50th (PAL) or 1/60th (NTSC) of a second.

The time resolution is 50 and 60, not 25 or 30!

If you deinterlace correctly you should reconstruct the missing scan lines instead of trying to get scanlines from one time capture to consolidate with one from a different time capture.

And yes many "deinterlacers" do it completely wrong!
