2:1 vertical reduction
Chris LaRosa
Reduces the size of each frame by 2:1 in the vertical direction only. A 1x2 non-overlapping matrix is used. This filter can also be used to deinterlace.
Alparysoft Deinterlace Filter is developed for elimination of interlace effect, that is caused by connection of two half-frames into one frame, as a result of it the picture looks blurred and striped.
Nearly identical to the unfold fields option within VirtualDub's built-in deinterlace filter except that it re-arranges the top field on the top and the bottom field on the bottom of a frame.
