De-interlacing PAL videos

Postby Archangel768 » Sun Feb 15, 2009 4:53 am

Ok well i'm at the point of ripping my dvds where i have my .AVS script loaded into VIRTUAL DUB MOD.
I am finding that there is a lot of interlacing in the video (lots of horizontal lines)

This is my Script so far.

mpeg2source("D:\Gundam seed v1\VIDEO_TS\gundam seed volume 1 .d2v\Gundam1.d2v")
separatefields
LanczosResize(768,576)
Limitedsharpenfaster()
Toon()
converttoyv12(interlaced=true)
Deen("w3d",3,3,5)
Undot()
AssumeFrameBased

I have "separatefields" due to a guide i was following to get rid of interlacing but now there is a lot of bobbing in my video and FIELD BOB doesn't seem to be getting rid of the bobbing.


The video Is PAL format and i need to get rid of the horizontal lines (interlacing) somehow.
Can anyone suggest a way of doing this?
Sorry is my post if confusing at all or is in the wrong section.

If you haven't checked, try the EADFAG found here

I'm not familiar with PAL footage, but from what I can see in your script, you have no deinterlacing going on at all, hence the combing all over the place.

I'm not very good at scripting, but you've got your script in the wrong order. First comes the deinterlacing, THEN the denoising, THEN the sharpening, THEN the resizing, and THEN the colorspace conversions. Also, you only need one item for sharpening or deinterlacing, otherwise it's overkill.

If under "sharpening" you include line thinning, line darkening, and so on, then I beg to differ. For example, combining FastLineDarken with, say, LimitedSharpenFaster can provide results similar to vmToon at much better speeds.

Thanks for all ur help guys now it is looking pretty good!

ok here is my new script

mpeg2source("D:\Gundam seed v1\VIDEO_TS\gundam seed volume 1 .d2v\Gundam1.d2v")
converttoyv12(interlaced=true)
fielddeinterlace()
Undot()
Deen("w3d",3,3,5)
Toon()
LanczosResize(768,576)

now the lines are gone and it mostly looks great. theres just this thing when the character moves. sometimes the character will be in two places at once on the screen like there is a trail. doesnt really matter too much if it is there but i thought it would be good if someone knew how to get rid of it.

is there a way to just edit my post instead of double posting?

You've encoutered the wonder that is frame blending. It apparently can be removed but I've never successfully managed to.

Should'nt this topic be in 'AviSynth' sub forums?
And s/s always helps people who are you helping you ;)

I find tomsmocomp(1,5,1) to be the best solution for most cases of PAL interlacing. The blending is pretty much impossible to properly remove, in the case it's there, it's just better to leave it there.
