View source for Cdeint


Bad telecined sources with blended fields seems to be normal in my country. The possible solutions for this problems are really rare. For example matchbob or tdeint(mode=1, tryweave=true) with unblend and a decimater or the the great but totally complex function restore24. So I tried to create a alternative for restore24 and this is the result.

Discussion can be found [http://forum.doom9.org/showthread.php?t=95924 here].

== Function ==

<pre>
function Cdeint(clip clp, clip "bob", int "bmode", float "nlv", float "hv") 
{
###### PREPARATION ######
global noisel = default(nlv,0)
global x = default(hv,0.9)

ord = clp.getparity() ? 1 : 0
tmpp = isyv12(clp) ? clp.leakkernelbob(order=ord, sharp=false, twoway=false, threshold=5).duplicateframe(0) : 
\	clp.leakkernelbob(order=ord, sharp=false, twoway=false, threshold=5).duplicateframe(0).ConvertToYV12()
one = tmpp.crop(8,8,-8,-8)
two = tmpp.crop(8,8,-8,-8).BilinearResize(640,352)
three = tmpp.crop(8,8,-8,-8).BilinearResize(352,192)

global testclip = (bmode==1 ? one : (bmode==3 ? three : two))
