Blended fields (a.k.a "ghosting")...

Post by devilmaykickass » Thu Feb 23, 2006 5:19 am

I'm having a real, real hard time getting around this one (my apologies for large images).

Image

I've tried to make several videos in the past using the Sailor Moon movies, but I just could never finish them because after testing I knew that there was no possible way to compress them to a reasonable size without them looking terrible because the blending KILLS compression (as if the quality wasn't bad enough already...what the hell kind of commercial company crams entire movies into 4GB of a double layer DVD?). All three of the R1 movie DVDs released by Pioneer are like this...no, not just parts, but the ENTIRE movies are like this. Even when you watch them on a DVD player, though when it's in motion it's nearly unobvious for the most part.

Also, aside of killing compression, it makes any methods of deinterlacing besides simply blending the fields together with "blur(0,1)" or the standard VirtualDub deinterlacer (and those still don't get rid of all interlacing) impossible, and just makes ghosting out of the already ghosted footage, killing compression even more and making things look worse. Using telecide (order=1) as I usually would gives me stuff like this (though every so many frames appear ok and intact):

Image

I'm not completely sure if that's due to the ghosting or not, but I've never had that happen before.

So I really have two questions:

A) Is there any way to get rid of or reduce blending/ghosting, or atleast deal with it in a way that won't completely kill compression and make editing hell?

B) Is there a way to properly deinterlace blended footage without blending it even more, or is what I'm getting a result of blended footage in the first place?

Help is greatly appreciated. I've never worked with ghosted footage before, so forgive me if there's something that's obvious to most people besides myself around here.

Special situations like this can vary from source to source. If you would make a short sample of the vob available (under 1 minute), I would gladly take a look and see what can be done.
You can make clips in DGIndex using file>save project and demux video.

Awesome.

I've uploaded a (very) short clip at the following link: http://rapidshare.de/files/13946466/VTS ... d.zip.html

I can't fix it!

For the jagged deinterlacing though, try
Tdeint(mode=1).Blendbob()
instead of Telecide()

Yeah, that fixes the interlacing issue for the most part.

Thanks for taking the time to look at it. I just wish I could do something about the blending. I've seen a couple videos that actually used it and made it look decent, like "Visionary", but I don't think she remembers what she did because that video was made quite a while ago, but it shows that decent quality is possible at a resonable filesize.
