== Abstract ==

FixBlendIVTC is a function to restore blend-deinterlaced telecined footage with
doubleblends and 50:50 blendweights.

== Description ==
Decimate (from [[Decomb]]) is the only function guaranteed not to mess up this filter, unless you follow the filter with RequestLinear from [[TIVTC]].

{{ParR|post|int|2|0-6}}
Postprocessing strength:
* 0 - No postprocessing
* 1 - 0 + chromablur
* 2 - Diffmasked pp (sharp and good for hq sources) - default
* 3 - 2 + chromablur
* 4 - Blurmasked restoring (more soften than 2, but sometimes less artefacts)
* 5 - Combines post 2 and 4 but without chroma.
* 6 - 5 + extra chroma (slowest).

If these postprocessing modes aren't strong or individual enough for you you can also use your own favourite filter on the restored frames. Therefore set a string with your setted filters. Use pp0 till pp6 for the postprocessing mode and add your filter like this:
post="pp4.blur(1)"
If you want to use a filter with inputstrings use three quotation marks like in the second example.

Post=0 is the fastest, post=5 is the best for bad quality and the slowest postprocessing mode.

{{Par|dclip|clip|none}}
This clip is used for the blenddetection and won´t be returned, so that you can preprocess for blenddetection without affecting the output. A light bluring or temporal stabilizing can be really useful sometimes, especially in a source with many artifacts, but normally this feature shouldn´t be used.

'''Note''': The blenddetectiondifferencing is also used for post 4 and 5. So a too strong preprocessing could maybe have a bad effect on the postprocessing, but I wasn´t able too produce such cases till now. Indeed sometimes this seems to be just better for the postprocessing.

{{Par|sbd|bool|false}}
SingleBlendDetection, it's a bool parameter you should set true for 12fps sources (anime/cartoons).

{{ParR|bthresh|float|0.1|0.0-2.0}}
The blendthreshold can be used to make the blenddetection less aggressive if there are some wrong detections.

{{ParR|mthresh|float|0.1|0.0-1.0}}
The motion threshold for the function. If the framedifference is smaller than mthresh the function don't trust the blenddetection and does nothing. This helps decimating and can avoid side-effects. Sbd enables allready some kind of mthresholding, but the 12 fps detection works with really low thresholds.

== Examples ==
<pre>
AviSource("blended.avi")
FixBlendIVTC(post=3)
Decimate(cycle=5,quality=0)
LimitedSharpen()
</pre>
<pre>
FixBlendIVTC(post="""pp2.deen("a2d")""")
tdecimate(rate=23.976,mode=7)
</pre>
== Changelog ==
'''''Foxyshadis'''''

'''v.1 - v.3''': 
Required manual offsets. v.1 had broken reversal. 
'''v.4''': 
Conditional, effective but very slow.

'''''MOmonster'''''

'''v.5''': 
Much faster, better detection & single-blend detection. 
'''v.6''': 
Changed parameters again, better motion mask/influence. 
'''v.8''': 
Sped up significantly, also more accurate single-blend. 
'''v.9''': 
Modified for less artifacts, more post-processing choices, bthresh.
