I need help on how to handle this video please

[pooksahib]

Hi - I recorded this off the TV (satellite) and it has plenty of interlacing 'combs'. I've applied separatefields along with Assume TFF and BFF but it looks odd and I just cannot work out what type of deinterlacing to use. I'd love some help, thanks - and Happy New Year to you all.

It's pure interlace. Bob it using QTGMC or some such.

This is normal interlaced video - 'combs' are visible only on progressive display when no deinterlace is applied to source.
You may follow manono advise and use QTGMC however you may be interested in faster and overall good quality yadif deinterlacer.

Thanks, lads. Ordinarily, I'd use QTGMC especially for such a short video as this. I used MeGUI, DGIndexer, QTGMC and the result is the wavy lines you see in the attachment. I don't understand how this should be, maybe someone knows of a reason?

Yadif, however, works fine.

Looks like motion analysis issue.

Those thick wavy lines looks like you resized vertically in a progressive manner while still in fields . (Don't resize, until after your deinterlace, or resize in an interlace aware manner)

I don't get those artifacts

Post your script

[jagabo]

Yes, a common mistake. When you resize an interlaced image vertically without taking into account it is interlaced, the two fields are co-mingled and can no longer be separated properly.

Thank you, well spotted! My TV recording was of a 4:3 programme sandwiched between two modern programmes. You can see what I did here:

LoadPlugin("E:\MeGUI\tools\avisynth_plugin\NicAudio.dll")
LoadPlugin("E:\MeGUI\tools\dgindex\DGDecode.dll")
a=DGDecode_mpeg2source("E:\zGet Down\gET DOWN.d2v")
b=NicMPG123Source("E:\zGet Down\gET DOWN PID 1452 L2 2ch 48 224 DELAY -38ms.mp2") 
audiodub(a,b)
LoadPlugin("E:\MeGUI\tools\avisynth_plugin\yadifmod2.dll")
Yadifmod2(order=-1)
Spline64Resize(720,540)
trim(36917,41049).fadein0(40).fout(70)++loop(200,41049,41049).trim(41049,41049+199).amplify(0).fadeout0(40)

Is there a single script that would give me QTGMC and a 4:3 AR? Thanks again.

[jagabo]

Replace Yadifmod2 with QTGMC.

[pooksahib]

Damn. It's the order they appear in the script, isn't it? Idiot! I'm not thinking straight yet...

[pooksahib]

Actually, I have options - I can do it using MeGUI's 'Clever Anamorphic' option:

global MeGUI_darx = 4
global MeGUI_dary = 3
LoadPlugin("E:\MeGUI\tools\avisynth_plugin\NicAudio.dll")
LoadPlugin("E:\MeGUI\tools\dgindex\DGDecode.dll")
a=DGDecode_mpeg2source("E:\zGet Down\gET DOWN.d2v")
b=NicMPG123Source("E:\zGet Down\gET DOWN PID 1452 L2 2ch 48 224 DELAY -38ms.mp2") 
audiodub(a,b)
trim(36917,41049).fadein0(40).fadeout(70).QTGMC()

or by resizing to a 4:3 ratio:

LoadPlugin("E:\MeGUI\tools\avisynth_plugin\NicAudio.dll")
LoadPlugin("E:\MeGUI\tools\dgindex\DGDecode.dll")
a=DGDecode_mpeg2source("E:\zGet Down\gET DOWN.d2v")
b=NicMPG123Source("E:\zGet Down\gET DOWN PID 1452 L2 2ch 48 224 DELAY -38ms.mp2") 
audiodub(a,b)
trim(36917,41049).fadein0(40).fadeout(70).QTGMC()
Spline64Resize(720,540)

Does anyone have a preference?
