extract a matrice from an xvid avi file ? [SOLVED]

[vhelp]

[SOLVED] -- Nov 14, 2011 mon a.m.

is there an app or utility that can extract the matrice out of an xvid encoded avi file ?

i'm working on a matrice editor tool that helps modify matrices more easily, but i have a lot of (past encoded) avi's in several folders that i can't identify the matrice used in those clips i encoded--a lot were experimental matrices--each filename has an inc index tacked on to help me view progressive quality results. now i do try to follow a personal rule, when encoding: to include the matrice 'filename' i used in the clip, and/or, few 'chars' that uniquely identify the matrice, but i wasn't consistant with a number of files using this practice. lets face it, we do get lazy from time to time.

if there is no app/tool, then, is there something, like a technique of some sort 'to decode the matrice' programmically ?

thank you in advanced!

Why reinvent the wheel?

AFAIK, Ligh's CQM Editor cannot "extract" the QM used in ASP stream.

There exists QuantDump.exe by neuron2, however it supports MPEG-2 video only.

I didn't say it did. vhelp says he's designing a matrix editor to modify (and create also, I would guess) matrices, and there already exists a very good one. I didn't mention anything about extracting the matrices used because I can't think of such a program offhand. I suspect there is one out there somewhere.

[vhelp]

thank you, manono, but i much prefer the one i'm currently developing. coding is one of my hobbies.

thanks el heg, i knew about that quant dump feature--and used it a few times, a good feature indeed--but thats for mpeg2's, i'm looking for xvid avi's because it relates to what i'm trying to accomplish, which by the way, i solved. but now to get the 'dll calling' code to cooperate in my project--there is no example for how to do it using the resource i found, so i'm winging it through debugging.

adding the ability to extract a matrice from an xvid will be a great feature to have!

also, it wouldn't hurt to add a feature to determine if other matrices (from a list, D/L's or my own, folder, etc) are duplicates or not in a custom list i'm trying to work out...and a few other ideas. thanks again.

snipet of the tool so far. . .

Hummm, the app looks nice

Especially because its window is resizable

The editors by Rockas and Ligh do not use resizable windows.

BTW --- if you manage to make your matrix editor "perfect" ,
you MUST release it,

otherwise, you'll have to face the "consequences"

i finally managed to get the routine to work--is in another app alltogether.

lots of pieces borrowed from other worthless tools i created.

now to strip it from that app and stitch it into matrice editor. will be a messy job.

what i also want to do--now that i think of it--is to add to the routine that tests for duplicates. this way i can tell right away if i already created the matrice or someone else did.

Any plans to support DivX/Xvid in MP4 and Matroska

vhelp, your tool looks good, but please change one thing - although 'matrices' is the plural form, the word is matrix, not 'matrice', as any mathematician will tell you.

[El Heggunte]

as any mathematician will tell you.

Actually that's a matter of etymology

BTW, the root of that word has to do with "womb" and "wood"

And no, there is NO "science" in giving new meanings to very-ancient ideas

[jman98]

as any mathematician will tell you.

Actually that's a matter of etymology

"Matrice" is a French word and I suppose in that I found a dictionary definition for it in English it is theoretically correct to use this spelling, but let's say that the French spelling is discouraged and not commonly used. So Gavino has a point. You're going to roughly have to go back to pre-Shakespearean English to find a time where "matrice" is considered the preferred way to spell the term in English.

[vhelp]

@ gavino, if no other matrix apps are named such then i can change it to 'matrix editor'

@ el heg, if you are refering to the matrix extraction part, then no..i hadn't thought of that since xvid was my primary path. or do you mean containers other than avi to extract matrix from. i can test and report results later. but i don't know anything about divx. i learned about the techniques for xvid through trial and error.

[El Heggunte]

Yes, Xvid remains Xvid, regardless of the chosen container. Also, you'd better not neglect the olde and goode *elementary streams*

And SFAIK, the differences between Xvid and DivX are:
a) the Xvid encoder offers more choices to the end-user ;
b) the respective "4CC IDs" when the container is AVI, a VfW-compatible MKV, or (gulp) ASF
