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 fast & simple noise reduction). See Input Help.Sharpen A mild sharpening is applied that is supposed to undo the blurring of simple deinterlace.
A slow feature that results in a small improvement.
May be counterproductive for noisy video.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.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.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.
