v.interlace v.interlace takes two streams and inputs and interlaces their video lines. v.interlace takes two streams and inputs and interlaces their video lines. The horizontal lines from the leftmost stream are placed in the even lines of the output stream. The horizontal lines from the rightmost stream are placed in the odd lines of the output stream. The resulting output stream has twice the vertical resolution of the input stream. The two input streams should be the same size and format.
