speed option (the slower the function the moreĪccurate it should be). Possible settings:Ġ - normal (should have the worst accuracy)Ģ - slowest (should have the best accuracy) Sets which field matching fuction is used. 1 = auto (TFM will set field to the same value as the order parameter) In certainĬircumstances changing the field that is used to match from can have a large impact It is recommended to set this to the same valueĪs order unless you experience matching failures with that setting. While correctly tweaking these values can increase matching accuracy they can also make things worse. These parameters give finer control over the matching operation, combed frame detection, and deinterlacing of combed frames. PP option through an overrides file (see the ovr parameter description) * You can manually control what frames should be marked as combed as well as the The clip2 parameter description for more info and to see how the PP settings effect * You can also use the "clip2" parameter to specify an externally deinterlaced clipįrom which TFM will take frames instead of doing the deinterlacing itself. Possible optionsĠ - nothing (don't even look for combed frames)ġ - find/hint combed frames but don't deinterlaceģ - dumb cubic interpolation deinterlacingĦ - motion-adaptive cubic interpolation deinterlacingħ - motion-adaptive modified-ela deinterlacing This controls how TFM should handle (or not handle)Īny combed frames that come out of the field matching process. * In terms of speed option 0 is by far the fastest and 5 is the slowest. The () at the end indicate the matches that would be used for that mode assuming order = 1 Mode 7 requires linear access to work correctlyīecause what match/field are used depends on previous match decisions.ġ = 2-way match + 3rd match on combed (p/c + n)Ģ = 2-way match + 3rd match (same order) on combed (p/c + u)ģ = 2-way match + 3rd match on combed + 4th/5th matches if still combed (p/c + n + u/b)ĥ = 3-way match + 4th/5th matches on combed (p/c/n + u/b)Ħ = mode 2 + extras if combed (p/c + u + n + b)ħ = mode 0 + field switching based on previous matches Mode 7 is is not one of the normal modes and is specifically for material with blendedįields that follows a specific pattern. finding good matches in sections with bad edits, orphaned fields, Somewhere in between options 0 and 5 in terms of risking jerkiness and creatingĭuplicate frames vs. The other settings (options 1, 2, 3, 4, and 6) are all (option 5) is the most risky in terms of creating jerkiness, but will almost alwaysįind a good frame if there is one. + trying the 4th/5th matches if all 3 of the original matches are detected as combed Safest of all the options in the sense that it wont risk creating jerkiness due toĭuplicate frames when possible, but if there are bad edits or blended fields it willĮnd up outputting combed frames when a good match might actually exist. Sets the matching mode or strategy to use. ![]() 1 = auto (use avisynth's internal parity value) The field order must be correctly set forĪccurate field matching to occur. They control the basic operation of the filter. These are the only three parameters most users should be concerned with or worry about setting. Int micout, int micmatching, string trimIn, int hint, int metric, bool batch, Int mthresh, PClip clip2, string d2v, int ovrDefault, int flags, double scthresh, Int cthresh, int MI, bool chroma, int blockx, int blocky, int y0, int y1, String outputC, bool debug, bool display, int slow, bool mChroma, int cNum, TFM(int order, int field, int mode, int PP. The other settings are described under the other various sections which should be pretty easy to figure out from the names. ![]() They are "order", "mode", and "PP" and are described under the "basic parameters" section. Really there are only 3 parameters most users should be concerned about knowing or ever setting. While TFM does have quite a few parameters, I have tried to categorize the settings so they are easier to manage. It does not decimate the resulting duplicate frames though, so to achieve an IVTC you must follow TFM with a decimation filter such as TDecimate(), which is also included in the TIVTC dll. TFM is a field matching filter that recovers the original progressive frames from a telecined stream.
