Line TBC with Avisynth script?

Hi maby someone know how to tweak this line tbc sortof or it align all field lines after a reference clip

it´s very slow

example Clip A is a bad align clip and Clip B is the good align clip of the same video or movie as Clip A

NonlinUSM you can find here http://avisynth.nl/index.php/NonlinUSM

Code:

#SetMemoryMax(1920)

#SetMTMode(1,8)



a=AVISource("D:\titanic\titanicSvideo_EDIT720.avi").Trim(463,2463)

b=AVISource("D:\titanic\titanicES10NoTBC_EDIT720.avi").Trim(17,2017)#.crop(0,0,-70,-0).AddBorders(70,0,0,0)# ES10 Capture



aa=a.AssumeTFF().SeparateFields()

bb=b.AssumeTFF().SeparateFields()



#287 or 288x2=576 Lines PAL

return stackverticaln(aa,bb,287).FlipVertical().Weave()



function stackverticaln(clip v,clip vv, int n) {

  n<1?get_line(v,vv,n):stackvertical(get_line(v,vv,n),stackverticaln(v,vv,n-1))

}



function get_line(clip aa,clip bb,int field_line)

{

line=field_line

top=line

bottom=287-line

clipf=aa.crop(0,top,-0,-bottom)



a_ref = aa.ConvertToYV12().NonlinUSM(60.0,2.6,6.0,8.5).greyscale().ConvertToYUY2().crop(0,top,-0,-bottom).AddBorders(0,0,0,1)

b_ref = bb.ConvertToYV12().NonlinUSM(60.0,2.6,6.0,8.5).greyscale().ConvertToYUY2().crop(0,top,-0,-bottom).AddBorders(0,0,0,1)



c_ref = Interleave(a_ref, b_ref)

mdata = DePanEstimate(c_ref,trust=0.01,dxmax=80,dymax=0)



c_stab = DePan(Interleave(clipf,clipf), data=mdata,offset=1,subpixel=2)



bb_stab = c_stab.SelectEvery(4, 1)

bbb_stab = c_stab.SelectEvery(4, 3)



return Interleave(bb_stab,bbb_stab)

}

I'm not really clear on what's happening here. It separates fields, blurs/sharpens and stabilizes.

That's not TBC.

At very best, that may hide timing errors, but that's true of any temporal blurring, or blurring in general. It's not pretty, but it can sometimes make terrible video more tolerable. Not enjoyable, just tolerable.

Hi SeparateFields() i use it to deinterlace so i can compare line after line to the reference clip

about this avisynth script i was thinking if it´s possible to run the same video or movie 2 times one time without ES10 and one time with ES10

and then align line by line the clip without ES10 to get it as good as with ES10 clip but without ES10´s DNR effects

Code:

a_ref = aa.ConvertToYV12().NonlinUSM(60.0,2.6,6.0,8.5).greyscale().ConvertToYUY2().crop(0,top,-0,-bottom).AddBorders(0,0,0,1) 

b_ref = bb.ConvertToYV12().NonlinUSM(60.0,2.6,6.0,8.5).greyscale().ConvertToYUY2().crop(0,top,-0,-bottom).AddBorders(0,0,0,1) 



c_ref = Interleave(a_ref, b_ref)



mdata = DePanEstimate(c_ref,trust=0.01,dxmax=80,dymax=0)



#this compare one line from Clip A to Clip B(the reference clip)

stackverticaln function calls get_line function 287 times to get a full frame so stackverticaln function stacks vertical all the lines it gets from the get_line function line by line

get_line function returns one line from Clip A but with the horizontal Offset that Clip B has

the sharpens that i do does not effect the final frame at all i only do the sharpens because the compare funtion DePanEstimate works better to compare the clips

if i understand correct DePanEstimate returns only the offset data that can be use to other functions

if you edit like this for example it only stacks 10 lines in the middle of the frame and works mush faster to good for testing

Code:

return stackverticaln(aa,bb,135).FlipVertical().Weave() 



function stackverticaln(clip v,clip vv, int n){

 n<125?get_line(v,vv,n):stackvertical(get_line(v,vv,n),stackverticaln(v,vv,n-1))

}

stackverticaln function loops and stack vertical line number 135,134,133,132,131,130,129,128,127,126,125
