Ugly interlacing on PAL DVD

...which I don't want on my backup, of course.

sample: http://www.mediafire.com/?sharekey=1...db6fb9a8902bda (0'40", 29 MB)

bob + remove duplicates gets rid of most of the interlacing, but at the price of a severe quality loss, and KernelDeint creates too much blur

unfortunately, this is as far as my AviSynth knowledge goes... is there a better way?

Hi-

It's field-blended from an NTSC source. You'll have to unblend it and return it to film speed. One such script might go:

LoadPlugin("C:\Path\To\DGDecode.dll")
LoadPlugin("C:\Path\To\MT_MaskTools.dll")
LoadCPlugin("C:\Path\To\Yadif.dll")
LoadPlugin("C:\Path\To\TIVTC.dll")
LoadPlugin("C:\Path\To\Average.dll")
LoadPlugin("C:\Path\To\RemoveGrain.dll")
MPEG2Source("C:\Path\To\Test.d2v")
Import("C:\Path\To\SRestore.avs")

Yadif(Mode=1,Order=1)#or your favorite bobber
SRestore(FRate=24)

Adjust the script for your names and paths. Get and read up on SRestore here (it's part of the R_Pack you'll download):

*Googles "How to make a d2v file"* (yep, I'm a newbie)

*tracks down Average.dll* (apparently I wasn't the only one having trouble finding it)

*runs script*

*gets error message about DGDecode.dll*

*fixes error*

*runs script again*

*falls off chair*

By Jove, it works! Thank you, thank you, thank you! *does little happy dance*

OK, done, looks nice!

One more question: the avi has 24.0000 fps (probably caused by "FRate=24")... shouldn't that have been 23.976?

I wouldn't be so sure, myself. If the source for the PAL DVD is an NTSC DVD (doubtful, in my opinion), then yes. If the source is an NTSC master made from film, then no. After all, 23.976 results from the drop frame flag, and film is 24fps. My opinion only, of course.

In addition, I've made allowances here. If it's really 24fps, by making it 23.976fps you lose one frame in every 1000 (every 40 seconds or so), resulting in a big jerk. If you make it 24fps and it's really 23.976fps, then you get an extra frame in every 1000, resulting in a much smaller and probably unnoticeable jerk at that point.

But if you'd feel better making it 23.976fps, just change the FRate.

Only slightly and really none at all now that I know there is a good reason behind it.

Thanks again!
