Deinterlacing wrongly encoded footage

[Xyena]

Hey i'm trying to currently deinterlace some footage i have on my hdd. and the footage is encoded wrong.
its from itv sometimes in the late 2000s i would think. not sure if anyone can help. QTGMC and CCD seem to both not work for this occasion as well and reinterlacing and then deinterlacing it again. and topaz video enhance ai did not help either. file is attached is of the video untouched.

You can't really deinterlace it because it's not interlaced. It was originally, but what you have is the two fields mingled together.
This is probably the result of it being resized while it was still interlaced to the progressive file you have now

It can probably be cleaned up a little but the damage is already done

[rrats]

Is that a reencode

[Xyena]

its a yt rip. so probably, idfk.
i am looking for actual help not morons that just say YEEEEP ITS SCREWED PAST OBLIVION.
bitch I KNOW. thats why i'm asking yall xD
cause maybe at least one of you will actually tell me something else i dont know.

Look for avisynth's "DeBilinear" or "DeBicubic". Try to re-resize back (find best parameters with trial and error) to the original 720*576 and then deinterlace again (if necessary).

^ That ain't gonna work

blur the video. it will have blending artefacts but it aint that eyehurting

[rrats]

Here's my attempt at restoring the video

Why?

1. you loose detail by resizing from 576 to 480 vertical pixels. that also includes the interlacing crap and makes proper deinterlacing impossible
2. video is compressed af

Another customer for BananaLacer.

In your case:

Spline16Resize(640,240)
Spline16Resize(640,480)
#Deblock_QED() #Optional

[rrats]

That also wouldn't work both because of the compression and the fact that those interlacing stripes are not aligned

[VoodooFX]

Wouldn't work what? What interlacing? What compression?

Your facts are wrong.

[If you are still confused then read the second post again (one from davexnet).]

[Alwyn]

I think that should be a 16:9 video, not 4:3. 16:9 looks more correct, and the ITV label is probably sitting just inside the 4:3 safezone, which means it should be further out to the left.

What interlacing?

They are not saying it's interlaced.

[VoodooFX]

There is no word "interlaced" in my rhetorical question too.

[rrats]

Your spline16resize states otherwise

[VoodooFX]

States what?

[rrats]

That you are dealing with interlaced video.

[VoodooFX]

That you are dealing with interlaced video.

That's wrong assumption on my sarcasm. Isn't sarcasm there obvious? Name as "BananaLacer" should be a dead giveaway, a smiley works as indication too.

I didn't want to resize to 480. My suggestion was to resize BACK to 576. And not with a resizer, but with DE-Bilinear which is made for this kind of situations, because it tries to take back a wrongly made resizing (while interlaced). If you find right parameters it is possible to deinterlace afterwards without too many artefacts.

In my opinion the clip IS truly interlaced (shot with a tv camera), and of course afterwards badly compressed.

I don't think either de-bilinear nor de-bicubic upscale do they? Downsize only

[VoodooFX]

Filters are named Debilinear and Debicubic, they are intended to work only on upscales.

Not an opinion, the fact: This clip is NOT interlaced.

It was interlaced 576px and then weaved into progressive, downsized and compressed to 480px. so interlaced.

I didn't want to resize to 480.

That's not what I meant. I said that by resizing the 576px video to 480px you lose details, that you cannot bring back by resizing the video to 576px. In this case it's interlacing. Debilliniar won't do much here

On an English forum you should understand English, otherwise you don't make any sense.

Same as above, sarcasm needs to be understood to be funny, not other way around.

What is the point of this statement?

[jagabo]

I don't think either de-bilinear nor de-bicubic upscale do they? Downsize only

That's what I found. When you Attempt to upscale with them you get an error saying "debilinear: does not support upsampling".

Yes. I thought the most likely use case of this problem
Is what this seems be, SD interlaced, resized smaller.
I tried that script you did, some months back,for that music video "Bellefire - All I want is you"
The script ran ok, but I couldn't find an obvious "good" value for the resize down

EDIT your sample looks pretty good

Oops. I didn't know that. Then my proposal doesn't make sense. Forget it.

I am of different "fact"-opinion.
