Video media is interlaced, meaning one frame consists of two fields representing different points of time. Since each field is sampled on only the odd or even scanlines, each field is missing half the pixels needed to make a full frame at that point in time. Deinterlacing is a process of interpolating the missing information on fields to make full frames at particular points in time. A missing pixel can be interpolated by vertical interpolation of the field at the given time or by temporal interpolation using the previous and next field or a blend of the two. Adaptive video de-interlacing calculates a separate blend factor for each pixel based on the amount of local motion, so that vertical scanline interpolation is used in areas of motion, and temporal interpolation is used in static portions of the scene. This preserves detail in static portions of the scene while removing interlacing artifacts in areas of motion.
Use the Deinterlace tool to perform the following steps of the deinterlacing process:
