Resolution problem while creating NTSC DVD from AVI

[vertical]

FulciLives,

Thanks!

Well... It is not that easy for my level of knowledge. The scripts I used to convert from PAL DVD to NTSC DVD was created by FitToDisc.

But I do not know how to do manualy all that you advised. I will try to adjsut it through FitToDisc but it will take a while.

Thanks anyway as now I know in what direction to move.

I agree with John. Redo the PAL2NTSC DVD using his numbers, and also convert the AVI to NTSC DVD using his numbers.

"royally screwed" - Il like that though -)

Thanks, guys. No doubt, you are right. But the picture I've got, I mean NTSC DVD> is of a great quality both on PC and my standalone and plays perfectly well.

Give me some time and tomorrow I will post the results.

You have a good night! It is 11:40 in Vancouver.

Assuming the PAL DVD is progressive you do this in your script:

crop(0,76,-0,-68)
LanczosResize(720,360)
AddBorders(0,60,0,60)

The MPEG-4 AVI should be progressive so you change it like this in your script:

LanczosResize(720,360)
AddBorders(0,60,0,60)

It is just that simple

- John "FulciLives" Coleman

P.S.
Just so you know the "syntax" goes like this:

Crop(left,top,-right,-bottom)
AddBorders(left,top,right,bottom)
LanczosResize(height,width)

Thanks again. It is really helpful.

"It is just that simple" - You are right, especially when you know what you are doing, right?

Can you please advise whether there is an AVISynth ghost removal filter?

I like to say that the answer to A/V questions like this one is in the details. The key detail missing here until just recently: the unaltered screen shots of each source. Once you gave that and I understood what you wanted to do (convert both to NTSC DVD) the answer was easy. But yes I do know what I am doing :P

I would imagine that there is but I don't know off the top of my head. Never had to deal with that situation myself.

Here is a link to AviSynth filters: CLICK HERE

If such a filter exists it would be there.

"yes I do know what I am doing " - Hopefully one day I would be able to say the same but for now...

Thanks. I know the page and browsed it but I cannot understand - which one would be ghost removal. There are very few descriptions on the page.

Well only if you are a BIG egotistical ******* like myself ... or manono

You are on your own for this one unless manono has a suggestion.

You might want to ask over at the doom9 forums. They have a forum dedicated to AviSynth and they are bigger egotistical ******** than either I or manono.

But they sure as hell know what they are doing. I am only a demi-god compared to the real thing over there 8)

Thanks, I will try but I have really bad experience with Doom9 forums.

Thanks, I will try but I have really bad experience with Doom9 forums.

Ask nicely and above all else come across like you know what you are talking about. That surely helps. They hate newbies more than we do ... at least in the AviSynth forum

Avoid anything remotely similar to "I am a newbie and have no idea what filter to use for this problem", etc.

*** EDIT ***
I just remembered that TMPGEnc Plus (an MPEG-2 DVD spec encoder) has a built-in GHOST REDUCTION filter.

If you use AviSynth with TMPGEnc Plus be sure to use this as your last line in the script: ConvertToRGB24() and that assums your source is progressive (or you are making it progressive in the script if the source is interlaced). With an interlaced source that is to stay interlaced you would instead use: ConvertToRGB24(interlaced=true)

I'm not sure what you mean by ghost removal, or how these ghosts got there in the first place. If this is something from a retail DVD, maybe you can upload a sample somewhere.

[vertical]

manono,

I mean a picture where you can see like the second but clear silouette of a person or of a car or any other object. Like the second but clear shoulders, head and so on.

[FulciLives]

See my last post ... I added some info to it.

Although as manono said a retail DVD should not have any "ghost" like artifacts.

"above all else come across like you know what you are talking about" - That's the hard part in my situation but I can try something like: "Hey, guys, I have every AVISynth filter in my huge collection bit one is missing - ghost removal. Is there anybody who has one?"

[guns1inger]

So where did the first image, without the black bars come from ?

[manono]

I mean a picture where you can see like the second but clear silouette of a person or of a car or any other object.

I know what a ghost/double image/blended frame is. I'm wondering how they got into the video in the first place. If from an AVI, then most likely the original encoder messed up. If from a DVD, then often upon reencoding, they can be fixed. For example, the RePAL filter can often fix the blended fields caused by bad PAL2NTSC conversions. Those things appear to be "ghosts" in the original DVD, but can be filtered out to a large degree when reencoded.

And that's why I asked for a sample. I'm learning that making suggestions to you is a losing game, as we can only guess, based on your often misleading information (and I'm being kind here). This whole thread could have been 2 pages shorter had you posted those pics first thing.

That website will allow you to upload a file that is up to (or just shy of) 100MB which is enough space for you to throw up a VIDEO SAMPLE from the SOURCE VIDEO that has the "ghosting" that you are talking about.

In this case a video sample (even if only a few seconds long) is best.

guns1inger, that was his first attempt at doing the PAL2NTSC conversion.

manono,

I am not lazy but sometimes I do not know what is required to make it easier. Sorry about that.

It is about AVI files. Here it is:

"that was his first attempt at doing the PAL2NTSC conversion." - Actually the second. The first one was without resizing, without any scripts but sharpening.

The second one (the one we are talking about) was with a script from FitToDisc but looks like with a wrong script -)

[manono]

I'm not sure I see any ghosts. I do see a bit of Edge Enhancement (sometimes called halos). Is EE what you mean:

[vertical]

manono,

I am not quite sure but it looks like it is not about EE.

I realize it is hard to see on my pic. I am sure you've met it - the clear line running around the object. Sorry I do not know how to expalin better.

Thanks for the guide!

Hello everybody,

With your generous help, I finally finalized my first project. I converted PAL DVD to NTSC DVD and converted NTSC AVI to NTSC DVD, joined the resulting DVDs and ahve made a movie.

The picture quality of the NTSC DVD from NTSC AVI is quite acceptable. The black bars are of the same size. Everything is fine.

I have a few questions though and would appreciate your advice.

1. To FulciLives: kindly advise how the scripts were created. I mean why these numbers?


2. If instead of the two pieces I just had a full PAL DVD and would like to convert it to NTSC DVD. Would be the srcipt FulciLives advised the only one to use or the one I used (the picture at the top of the page 2) would be OK too?

The NTSC DVD that I've got with my script, what's wrong with it? The picture is of a good quality. It can be played on a standalone player with no problem.

The difference between the movie from my script and from the one FulciLives advised is that my final movie has no black bars while watching on TV while there are black bars while watching the movie resulting from the FulciLives script.

Do both have the right to exist or only one? Why?

Thank you!
