Description
===========

MVTools is a set of filters for motion estimation and compensation.

This is a port of version 2.5.11.20 of the Avisynth plugin.

Some changes from version 2.5.11.9 of the SVP fork have been incorporated as well (http://www.svp-team.com/wiki/Download).

The filter DepanEstimate was ported from the Avisynth plugin DepanEstimate, version 1.10.

The filters DepanCompensate and DepanStabilise were ported from the Avisynth plugin Depan, version 1.13.1.


Differences
===========

* All:
    * Free multithreading, courtesy of VapourSynth.

    * Parameters are all lowercase now.

    * YUY2 is not supported.

    * Grayscale, 4:2:0, 4:2:2, 4:4:0, and 4:4:4 are supported, except for DepanCompensate and DepanStabilise, which don't support 4:4:0.

    * Up to 16 bits per sample are supported.

    * The audio is definitely not killed.

    * No "planar" parameter.

    * "isse" parameter renamed to "opt".

* Analyse:
    * No "temporal" parameter, as it's sort of incompatible with multithreading.

    * No "outfile" parameter.

    * No "sadx264" parameter. If opt is True, the best functions imported from x264 will be selected automatically. Otherwise, only C functions will be used.

    * New parameters "fields" and "tff".

    * The optimised SAD, SATD, and SSD functions from x264 have been updated to the latest versions (as of September 2014).

    * Block sizes of 64x32, 64x64, 128x64, and 128x128 are supported.

    * The "dct" parameter can be 5..10 even with blocks larger than 16x16.

* Recalculate:
    * Same as Analyse.

* Compensate:
    * No "recursion" parameter. It was dodgy.

    * New parameter "tff".

* Flow
    * New parameter "tff".

* SCDetection:
    * No "ysc" parameter. The input frames are returned unchanged, with the ``_SceneChangePrev`` or ``_SceneChangeNext`` property attached.

    * No "isse" parameter. It wasn't used.

* DepanAnalyse:
    * Formerly "MDepan".

    * New parameters "fields" and "tff".

    * No "log", "range", "isse" parameters.

* DepanEstimate:
    * New parameters "fields" and "tff".

    * No "range", "log", "debug", "extlog" parameters.

* DepanCompensate:
    * Formerly "DePan".

    * No "inputlog" parameter.

* DepanStabilise:
    * Formerly "DePanStabilize".

    * No "inputlog" parameter.

    * Methods -1 and 2 unavailable.

If *fields* is True, it is assumed that the clip named *clip* first went through std.SeparateFields.

For information about the other parameters, consult the Avisynth plugins' documentation at http://avisynth.org.ru/mvtools/mvtools2.html or http://www.avisynth.nl/users/fizick/depan/depan.html. This will not be necessary in the future.


Compilation
===========

FFTW3 configured for 32 bit floats is required ("fftw3f").
