AVSynth and Premier

eadsja · Post by **eadsja** » Mon Jun 20, 2005 10:36 am

Allright, I've been going through the guides for the last two afternoons and I've got a couple of specific questions. To make things easier, here is what I'm using:

The AMV App V. 2.1
Adobe Premier Pro V7.0

Problem 1: I get this error messages whenever I CLOSE adobe Premeir. It doesn't seem to be hurting the program it'self (everything appears to be working fine, I still have yet to attempt an export). I remember reading somewhere to defrag the hardrive, and check the physical memory system (which seems to be ok). They only started appearing AFTER I installed the AMV App, so I am wondering if one of the codecs or plugins is not working propperly -

Adobe Premier Pro.exe - Application Error

"The instruction at '0x4f91177" referenced memory at "0x0e96328". The memory could not be "read".

My theory is that the pluggins were designed for Premier pro 6.0 and 1.5.1. Is one of my settings wrong or did I install the wrong program (I can't seemt o find anything for Pro 7.0 specific).

I Know this is more of Video Edditing question, but it deals more with software settings than how to actualy use the program, so here goes:

Problem 2 - Wierd Aspect Ratio

The video I am using -The Return of the Cat - DVD has a really wierd aspect ratio that I can't tell if I am manipulating it correctly.

On the box it says it has a ratio of (1.85:1) and my DGIndex says it is wide screan 16:9. That means it should be animorphic video right? But when I use the 840x420 lanczos resize, it looks even more pixilated.

Premier has no 1.85:1 aspect ratio (even in the custom fields). The closest thing to it is D4/D16 Widescreen 16:9 (1.896).

Is this the same Aspect Ratio? I am making the assumption that it is animorphic (because I don't see any letter boxes on it) but when I resize using LanczosResize the whole image looks -more- pixelated as opposed to the smooth lines I got when I did the same to an Akira DVD (where I actually gained quality by resizing).

Should I just leave it at 720X480 or try to propperly format the silly thing even though I have not made any attempt to adjust for the Pixel Aspect ratio?

Second, I've stared at the friggin Pixel aspect ratio explanation for three days now, and it still sounds like greek. I am lost in the sauce without a spoon. I am hesitant to start edditing until I get the source video correct.

Thanks for the time guys.

I don't have an answer for the plugin thing, but I feel I must clarify this --

The progression of Adobe Premieres goes like this:

Premiere 5.1 --> Premiere 6.0 --> Premiere 6.5 --> Premiere Pro (1) --> Premiere Pro 1.5

There is no such thing as "Premiere Pro 7.0" or, even worse, "Premiere Pro 6.0".

So I have Premier [Actual] and not some crazy X.0 version. On the install disk the menu says "Install Adobe Premier Pro 7.0" But thank you for the clarification.

What are the major differences between Pro and Pro 1.5 (I am using a film student's hand-me-down copy that he gave me.) And I could not find a way to upgrade from my current version to 1.5 (I thought it would be a patch fix. Though it feels like a completely different version upgrade).

Second: Do you have any advice how to insert custom aspect ratio's into Premier [Actual] so I am exporting out of premier at the same rate I am importing?

What I am finally doing is learning how to create lossless master videos before I begin compressing to everyone favorite distribution codecs.

Is there another guide that further simplifies (or goes into greater detail) how to manipulate the aspect ratio directy through AVSYNTH or a way I can work around it in Premier?

I don't quite understand the basic concept of the aspect ratio (except that at 16:9 it is more compressed so when it is shown on a wide screen it comes out correctly). It's blowing my mind.

Gah...

The version at http://videoeditorskit.sourceforge.net/ should have fixed this error.

Just to be clear: the version of the plugin in AMVapp is v1.5, right?

On the box it says it has a ratio of (1.85:1) and my DGIndex says it is wide screan 16:9. That means it should be animorphic video right? But when I use the 840x420 lanczos resize, it looks even more pixilated.

There is no native support for the 1.85:1 aspect ratio on a DVD. What's done to support it is that the video is encoded anamorphically at 16:9 and further resized to get it to the right aspect ratio.

I'm not sure where you're getting 840x420 from. At a 1:1 pixel aspect ratio, that's a display aspect ratio of 2:1, which is way off...

Premier has no 1.85:1 aspect ratio (even in the custom fields). The closest thing to it is D4/D16 Widescreen 16:9 (1.896).

Is this the same Aspect Ratio?

No. Widescreen DVDs have a display aspect ratio of 1.77...:1, and a pixel aspect ratio of 40:33 (well, 96:79 to be pedantic...)

D4 and D16 are digital television formats.

I am making the assumption that it is animorphic (because I don't see any letter boxes on it) but when I resize using LanczosResize the whole image looks -more- pixelated as opposed to the smooth lines I got when I did the same to an Akira DVD (where I actually gained quality by resizing).

Have you tried viewing it in VirtualDub, or instructing Premiere to not reinterpret the footage?

Should I just leave it at 720X480 or try to propperly format the silly thing even though I have not made any attempt to adjust for the Pixel Aspect ratio?

Two options:

(1) leave it the way it is, compensate in everything you do, and correct the aspect ratio at the end. For example, all graphics generated by you will have to have the same "squish".

(2) Convert the footage to 1:1 pixel aspect ratio. The closest you'll get in integers is 853x480; however, 853 is odd, and no one likes odd numbers, so 854x480 or 856x480 would be closest.
That's a direct conversion from an NTSC 16:9 display device to a VGA 1:1 device. You may have to do some cropping to get rid of black borders to ensure that the aspect ratio works out ok.

Second, I've stared at the friggin Pixel aspect ratio explanation for three days now, and it still sounds like greek. I am lost in the sauce without a spoon. I am hesitant to start edditing until I get the source video correct.

The pixel aspect ratio is the aspect ratio of each pixel in the screen, whereas the display aspect ratio is the aspect ratio of the entire screen.

To illustrate:

Code: Select all

       screen width
    ____________________
s. | _
h  ||_| ph
e  | pw
i  |
g  |
h  |
t  |

screen width / screen height = display aspect ratio
pixel width / pixel height = pixel aspect ratio

The resize calculator included in the avtech guides handles resizing across different PARs for you. The formulas for conversion are also linked in that guide.

Is there another guide that further simplifies (or goes into greater detail) how to manipulate the aspect ratio directy through AVSYNTH or a way I can work around it in Premier?

Thank you.

I will give all this a try and tell you how it comes out.

I just installed the latest and the greatest, but I still came out with the close memory read error. The plugin is 1.5 right? On the "About Adobe Premier" menu selection the product version is "gasp" Adobe Premier Pro 7.0. Is my software version incompatable with the plugin?

You said it was a know error? Is it going to hurt anything to leave it 'as is' or is there another fix?

Thank you a lot for the aspect ratio help. It's still swiss cheeze, but I think I am slowly starting to get it.

No. I fixed the big crash error that comes up when using the AVISynth plugin in Premiere Pro.

What you're experiencing is either a different crash error or a crash condition completely unrelated to the AVISynth plugin. I'd need, at the very least, stack backtraces to draw any sort of conclusion, because I know the thing doesn't crash here.

What steps can I take to determine whether or not it is my system with the problem. What can I do to get that information to you for your project?

i have a similar error
but it happens when i read avi's with vdub mod/avisyth,

"The instruction at "0x02118bfc" referenced memory at "0x02143888". The memory could not be "read".

with adobe premire pro 1.5:
"The instuction at "0x1ad98bfc" referenced memory at "0x1ack38x8". The memory could not be read".

yes updated AMVapp, different ffdshow cuase the one wiht the app is buggy, but i had the same type of error with amvapp's ffdshow.

and just to be clear...you know the Adobe Premiere Pro 7.0 was a marketing error right? It was suppose to be 1.0 but something happend and it was put as 7.0. if i can find the link on adobe forums ill link it.

EadsJA <---------- Someone who fiannly pulled his head out of his but in hopes of actually Learning an artform.

I didn't know that about premier pro. I got the coppy from a friend, "I've got something better now". And I just lit up like the fourth of July.

The error, seems benighn(sp). I have not had any system crashes and my projects still save. Let me see if I can reproduce your vdub mod/avisyth. What do you do to make it happen (I do all my avsyth scripting with a txt document and a bat file so I havn't seen the need to use it yet)

i just open video via avisyth
and i try opening a video that is XVID MPEG 4
then it says it cant and i shut it VDub down and i get the error

im more interested in the adobe error though as to why it is doing that...
