DVD2DVD Deinterlacing Problem

[WhipHubley]

Hi there,

I have The Abyss on PAL DVD which sadly is a 4:3 letterbox widescreen transfer - bah :-(

So I decided to use DVD2DVD to convert it into an anamorphic 16:9 version.

Unfortunately after I did this the resultant MPEG2 file was horribly interlaced.

I chose to scrap this version and start again, this time adding in a Separate Fields / Select Every deinterlace.

But this version ended up looking extremely strange. The image was split horizontally, with the lower half being completely green, and the movie being squashed up in the upper half - very odd.

I enclose my log file below - can anyone see what I've done wrong, or advise me on a course of action to fix this?

Thanks very much.

Hi,

Let me guess. You have the interlaced PAL version. I did this resizing by selecting Telecide (PAL) in the deinterlacers. It is very difficult to resize interlaced material. In fact some of the sharpest brains around here, claim that you should not do it. However, telecide gave me an acceptable result.

BTW, if you had used the 'Preview Video' function ('GO' Button), then you would have seen the bottom half was green with the "Separate Fields / Select Every deinterlace" option. This happens on my computer as well.

Other options which do deinterlace without the green picture (use the preview to check) are 'Smartdeinterlace" and "Blendfields". It is upto you to determine which looks best; just encode 1 chapter with the appropriate maximum average bitrate set to your value of 3429 (make sure you put it back to 7200 afterwards).

Hope this helps, regards,
Bob

Thanks very much, I shall give this a go and report back.

I can assure you that I did check several preview clips before I began encoding and they looked fine - very impressive in fact. Which is why I was so gutted with the result!

I'll have a go with Telecide.

Thanks again.

If the source is field-shifted, Telecide should make it progressive. If it's fieldblended, Restore24 can help you.

Deinterlacing is not an option is this case;) If nothing can help you, encode as interlaced.

Hi Boulder,

Can you elaborate further on your above statement?
You seem to be suggesting that deinterlacing is a not an option? I am confused.

The source is definitely interlaced. If you re-size it without first deinterlacing, you see horrendous combing when there is movement.

Regards,
Bob

[Boulder]

It may appear interlaced, but I am quite sure the original was shot in 23.976fps.

If a PAL version of a Hollywood movie appears combed, it's in 99% of the cases either field-shifted (which Telecide(order=1) will fix) or fieldblended (when the NTSC->PAL conversion has been done in a wrong way). In the latter case Restore24 will restore the original, progressive frames and return a 23.976fps clip. This can then be converted to a 25fps with AssumeFPS(25) , just as the conversion should have been done in the first place by the releasers of the PAL DVD.

If you could get a small unprocessed sample of a scene with motion, I'd be happy to check what it is.

[WhipHubley]

bobwillis - telecide worked a treat, thanks very much.

Boulder - just out of interest, if I were to try a Restore24, what are the parameters I need to pass eg,

Restore24(?, ?)

or something?

thanks again.

[Boulder]

The documentation that comes with the Restore24 package is quite good, and there's an example script included as well.

Basically it's just


MPEG2Source("path\clip.d2v")
AssumeTFF() # or AssumeBFF() for bottom field first video
a0=KernelBob(order=x,threshold=0) # x=1=TFF, x=0=BFF
b0=MatchBob()
Restore24(a0,b0)


This will restore the original progressive frames at 23.976fps, that's the default. If your source isn't fieldblended NTSC->PAL conversion, you should use different arguments in Restore24. They are explained in the docs.

[WhipHubley]

Nice one - thanks.
