View Full Version : Ghosting = Interlace?

My DVD source which appears to be progressive has a bit of ghosting. Basically, a bit from a previous frame remains in the next one. Is there any way to reduce that by deinterlacing or something or does that have nothing to do with the ghosting I'm experiencing? The ghosting is most likely due to the 24fps film conversion to NTSC.

Ghosting and Interlacing are not related in first case! However Ghosting may be the result of using a bad Deinterlacer (e.g. "Blending"), when converting from Interlaced to Progressive.

Furthermore what you are seeing may very well be the result of a bad NTSC to PAL conversion, which often is done via "Field Blending" and results in significant Ghosting artifacts all over the place.

Please upload a short clip of your unprocessed original source...

It's the original that has ghosting. Everything I said was in reference to the original. The footage on the DVDs is captured 24fps film converted to NTSC which is what I suspected may be causing the ghosting. I'll upload a short clip from the original VOB when I get home (in a couple hours).

Umm... I can't find a way to just cut a small piece of the original VOB without re-encoding. The shortest clip I can pull from there is the entire opening which is 1 minute and 45 seconds about... Is that okay or can I get in trouble for that?

You can use DGSplit to cut the VOB into segments.

What I said still applies. A bad format conversion and/or bad deinterlace can be found on many "original" discs, unfortunately :rolleyes:

DGSplit can be found here:

Sumawo13, thanks, maybe I'll try that if necessary.

Lord_Mulder, so, is there any filter that can correct this or is it as I suggested it might be (the ghosting is embedded into the frames making it impossible to just remove from the picture)?

If what you have is truly blended content, there are several restore functions, srestore() is a commonly used one - search that thread for usage and examples.

I'll test it out and see what happens. Thanks.

Yeah, SRestore() just makes it choppy, it's not something that terrible. Here's a short clip of the original VOB where what I'm talking about you can see for yourself. You might have to look at it frme by frame. Check at parts where a previous frame had a lighter colored spot which turned dark in the next one. That's where it's most visible.

# 0.) Index the VOB (your sample) with DGIndex ...

# 1.) Load the indexed source ...
Mpeg2Source("D:\Ghosting_(Typhoon859).d2v")

# 2.) The source is telecined, so do IVTC ...
TFM().TDecimate()

# 3.) ... and be done
Return( last )

:sigh: Now, where's the ghosting are you talking about ... ?


Hint#1: In your thread about cropping, some knowledged people told you how-to and how-NOT-to. Listen to them.

Hint#2: You've too little knowledge of the very basics, yet. This forum is full of information. Go figure.

The ghosting is in the original so obviously it turns out.. ghosted in the encode. The ghosting is very subtle. I think you might've just not noticed it. Later, I'll post a frame from there where it's apparent.

Maybe it was just telecine that I was seeing so when I get home (5 hours, I'll check your encode). Thanks for taking the time to do this.

Maybe the results of a "slow" LCD screen?

Didee, I just checked your encode where you did "TFM().TDecimate()". I tried to see any sort of difference but I couldn't find it. The difference I'm guessing is in the properties of the video itself, improving how well the other filters work?

Lord_Mulder, no, that's not the reason. Here, I'm posting some frames where it's apparent.

I can see it as well on my CRT monitor. I'm not sure you'd get rid of that though.

Yep. That's what I thought in the beginning. I think that it's pretty much drawn into the frames, the way it was done. There's no way to undo it.. :/
