Well, either no one has had any problems or no one uses it

.

I just posted v0.9.6, haven't had time to work on improving the edge-directed interpolation, but I did manage to add built-in combed frame detection and per-field weaving.

Changes from v0.9.5:

+ Added full parameter, allows for ivtc post-processing. full defaults to true.
+ Added cthresh, chroma, and MI parameters... these are used when full=false and with tryWeave option
+ Added tryWeave option, allows TDeint to adaptively switch between per-field and per-pixel motion adaptation. tryWeave defaults to true.
+ Improved field differencing
+ changed mtnmode default to 1

Some explanations...

Full works the same way as the full parameter in fielddeinterlace(). If set to false, then all input frames are first checked to see if they are combed. If a frame isn't combed, then it is returned as is. If it is combed, then the frame is processed as normal. Full can only be used when mode = 0. Full defaults to true.

tryWeave, if set to true, works like this... The most similar field to the current field (either prev or next) is calculated. A new frame is then made by weaving this field with the current field. This new frame is then checked for combing. If it isn't combed then it is returned. If it is combed, then normal processing (as if tryWeave=false) is done. This allows TDeint to adaptively switch between per-pixel and per-field weaving. This idea is taken from scharfis_brain's suggestion earlier in the thread and his matchbob() function. tryWeave defaults to true.
