Deinterlace Help
Fields Choice For a movie of the same length and frame rate you select "Top field", "Bottom field" or "Blend".
Usually there is little difference between "Top field" and "Bottom field". "Blend" makes motion a little smoother, but individual frames suffer from ghosting.
For double duration (= half speed slow motion) or double frame rate (good for 50/60p compression/playback) select "Both fields".Adaptive When available select this option for slightly better image quality in non-moving image parts.
When checked some addtional options become available in the input tab (block match theshold, remove jaggies and noise reduction). See Input Help.Half height If you want to extract one of the two fields (loss free) select either "Top field" or "Bottom field" and select "Half height". Save as '2vuy' for lossless extraction.
If you extract both fields (in two steps) they can be reinterlaced again if necessary.Filter chroma If you still see interlace-like artifacts in edges of moving colored objects, even after checking "reinterlace chroma" in the input pane, then try this vertical filter. Local "Local" is a new deinterlace method which may preserve a little more detail. It only deinterlaces the areas where the "comb teeth" occur.
"Local" is slower than the standard way. It has its own "remove jaggies" method which is better (and slower) than the old way.Move top field down This is a rarely needed option for "both fields" output. Computer graphics output to TV by old game computers may need this to prevent vertical jitter.
