Sure your codec compresses the fields individually if you have this problem.īecause interlace lines don't compress very well. Reconstruction is completely non-destructive. This can easily be corrected by delaying allįrames by one field which is exactly what the PAL movie deinterlacer does. However, sometimes the capture card gets it wrong and merges fields that Movies), there should be no interlace lines, since the fields belong to the sameįrame. If, on the other hand, you have captured video with real 25fps (such as most PAL But I recommend that you use my field shift filter below Subframes and double the frame rate in which case you won't need to do anyĭeinterlacing at all. You need to use a "real" deinterlacer suchĪs the area based deinterlacer below. The fields differ (usually due to motion). When these fields are merged into the full frame, interlace lines appear where That for 50fps video, each frame will consist of two subframes, or "fields". I believe VirtualDub's newer FieldDelay filter does the same thing as this filter.)ĥ0fps video with half vertical resolutionĢ5fps video with full vertical resolutionīoth of these are usually captured as 25fps full resolution video which means
