The Time Based DeInterlacer filter was designed to deinterlace an interlaced video. One field is interpolated, the other is returned unchanged. Interpolation is done pixelwise in the time dimension Interlaced video consists of frames with two fields, a top field (all odd lines) and a bottom field (all even lines, counting up from one). The fields show the filmed scene at different times, because the camera that was used made twice as much pictures per second as the framerate is. When viewing such a video, the player (generally a TV set) shows first the one, then the other field of a frame and then goes to the next frame which again consists of two fields. Processing interlaced video material with VirtualDub (and a lot of other programs) means to ignore that the fields are shot at different times and to show both fields at the same time as one image. That results into interlace lines in moving scenes. To correct this, there are the deinterlacers, programs (or "filters") that generally blend each two lines in a frame. But all the interlacers I found only make the interlace lines go away by blurring the areas that show motion or even the whole frame. They don't use the fact that the one field shows a picture made a little earlier than the other field. It doesn't matter in general, but with my corrupted material, it does. Main features: it returns the picture as it could be at the given time it only has to interpolate one field, leading to relatively sharp pictures it doesn't have a "moving areas detection", but it doesn't have to! when there's a scene where nothing is moving, the pixels don't change, also the average value calculated by TBDI is the same it's simple and fast (not assembly optimized, but fast because of the simple algorithm) it's the only way to deinterlace that strange processed material described above
