== Examples ==
ReMatch with default values:
[[DGDecode|MPEG2Source]]("IVTC source.d2v")
ReMatch(combthresh=12, c2thresh=6, scenethresh=20.0, orphanmode=2, orphanthresh=8000, guidecycle=5, guidethresh=10, ovrfile="", mask=false, debug=false, mmx=true, isse=true, sse=true)
 
 
== Changelog ==
<pre>
v0.91:
- Major speedups when using an override file when debug and mask are disabled. Be careful when using this with Telecide overrides, as it seems that Telecide
handles the 'previous' field different than ReMatch and often times, when previous is specified and works with Telecide, it will be different with ReMatch.

v0.90:
- Added basic, experimental Telecide override code. It does not support ranges, so each frame must be on a different line in the override
(YATTA is fine to use, though Telecide would be faster). It does not work on the first frame of a video (frame 0) but seems to be good otherwise.
I will add full override support later.

v0.84:
- Fixed an iSSE bug.

v0.83:
- Tweaking orphan detection.

v0.82:
- Fixed another bug with guidecycle at 0. Added c2thresh, which was previously a hardcoded value.

v0.81:
- Fixed a bug with setting guidecycle to 0. Changed default settings again.

v0.80:
- Disabled MMX/iSSE optimization for comb mask. Added some chroma consideration. Chroma combs are not counted, but chroma is considered when finding combs in the luma.
Overall result should be slower but more accurate. Default combthresh is now 18. Default orphanthresh is now 6000, which should be okay due to scene detection,
but may be increased as required.

v0.78:
- Added options to disable, MMX, iSSE and SSE. At the moment, SSE is not used. I don't know if I will ever have use for it in this plugin, but I will put it in anyway.
If you disable MMX, iSSE and SSE are disabled as well. If you disable iSSE, SSE will also be disabled. Note that most of the MMX optimizations also use iSSE,
so disabling iSSE will disable most optimizations.

v0.77:
- A little more optimization. Fix bug in assembly added in 0.84.

v0.76:
- When we drop to pattern detection and it can't figure it out, use the field with the least number of detected combs, not the current field. Also, some more tweaks to not
allow pattern detection to pick a field that is obviously wrong.

v0.75:
- Speedups if you disable orphan detection (orphanmode = 0). I don't recommend you do this unless you are absolutely sure your source has no orphan fields.

v0.74:
- More MMX/iSSE optimization. Fixed a bug dealing with line pitch, though I never did see this bug do anything. Changed orphanthresh default to 50,000.
When I added the scene change detection, it made orphan detection easy enough to not need such a high thresh.

v0.73:
- Removed some debug code I accidentally left in last time.

v0.72:
- Added scenethresh. At the moment, it's only used for detecting orphan fields.

v0.71:
- Some fixes in pattern guidance. It should no longer crash and it should be more accurate. Just set guidemode to 0 or lower the threshold if it's not accurate.

v0.70:
- Up to 8 pixels on the left and right of the picture are no longer used to count combs as misdetections seem to happen in those areas in the comb mask.
This does NOT affect the output picture. Also, added pattern guidance.

v0.60:
- More rewrites and optimizations. Fixed a major bug with comb masks that made the current field preferred. Changed default settings.

v0.50:
- Major code optimizations, including my first time ever writing assembly, so please be patient if stuff is buggy! More optimization soon.

v0.40
- Code rewrites, a lot added, will make it a LOT slower. Removed weighcombs. Does some filtering to try not to get false positives,
which is what causes most of the slowdown. Changed default options.

v0.30:
- Code rewrites, should be faster. Removed ovrthresh. Added a comb mask. Added a weighted comb threshold. Changed default options.

v0.20:
- Implemented orphan handling.

v0.16:
- Fixed a comb counting bug. This should be fairly usable now, but it still isn't good at detecting jaggy lines.

v0.15:
- Added ovrthresh, corrected debug mode.

v0.10:
- Initial version.</pre>
