Excellent comparison of MCF, Ogg and AVI ...

[ChristianHJW]

done by ingoralfblum today : http://sourceforge.net/docman/display_doc.php?docid=9810&group_id=47402 .

He said this was done in a hurry with not much time adn there is much more to be added, but i guess its giving a pretty good impression why i personally favour MCF ...

MCF does look pretty good in comparison, but how close is it to actually being usable with the level of sophistication of ogg today? (that is to say, essentially a work-in-progress version capable of creating finished, usable content by a reasonably knowledgeable person.) because it's one thing to say that its specification looks good in comparison, and it's another to say this finished movie performs better by comparison.

Tronic, Robux4 and Ingoralfblum are working hard on creating the first MCF parser right this moment. Once it's out testing can begin.

Ogg-Vorbis hasn't been out for a very long time yet and already people are using it en-mass. That shows that progress can go very fast indeed.

I hope MCF will get an equally fast kick-off once it is launched.

Marty has his own theory on things :)

goto Marty's Corner.....

(I wonder if this will get like a race?) :)

Cheers,

You are very good at racing yourself Nic (can you say XviD? :) ). Any chance you'll be joining the developers on this project?

[Nic]

I will....& I mean too, but I can't work if I feel im stepping on peoples toes & egos.....

Im waiting for things to calm down.... :)

(Also, with folk like Ingo, your in very capable hands :) You probably dont need me at all)

Take Care,
-Nic

ps
I also had a little hand in Marty's development direction :)

[MaTTeR]

Judging by the number of emails I'm getting from the Dev list I'd say it's picking up steam quite nicely.

I have no doubt that we will have hords of people to test and adopt MCF. I for one will be at the fron tof the line :)

EDIT- Nic, it will be great to know your help out as well...erhh after the Xvid DSF. LOL:D

Lets be realistic guys, right now our coders are indeed working hard, but they are still in the process of defining basic structures. What i really like is to see how great the teamwork is between those guys, i have the feeling ( allthough i understand only half ) that the mcf specs are greatly enhanced right now from day to day. This is the time to do this now as there is nothing out yet ....

There was another ( strange form of ) input coming from this guy here : http://www.powerdivx.com/phpbb2/viewtopic.php?t=272 . He was putting water on Marty's and Nic's mills by saying we dont need a new format, the extended OpenDML AVI specs can do a lot more than commonly known .... but in the end it seems he didnt have much arguments left against ingo and roBux4 .... ( Tronic didnt even participate in the discussion ;) ) ... but believe it or not, his arguments against mcf were leading to a few new ideas it seems :D !!

[Neo Neko]

Hehehehehehe. Yes indeed. Tronic and the others are not just trying to re-invent the wheel. They are making better steel belted radials! :D

i never liked the avi format
and i know many people that prefer mpg1 to divx cause divx...is avi...
we heard many times that divx brought the mpg4 compression from a "closed" format like asf to an "open" format like avi...
i dont know if avi could be really considered an open format, sure all video editors supports avi,but, not if the avi is incomplete or corrupted.
so, one year ago, i suggested here(and i got almost killed...) and on the opendivx forum to implement divx in the mpg format, or in a new format with the advantages of mpg.

i hope that all the advantages of mpg will be present in MCF,and maybe something better:
-ability to paste movies with the simple dos copy command
-paste a mpg header to mpg data and play them
-play the movie also if corrupted.

But also mpg has problems with these points when audio is involved,es. Vdub wont load or process mpg with audio corruption,while always works when the mpg has not audio
(but i know that MGI wave can process also heavyly corrupted mpg).
mpg with audio cant be pasted in dos....
so an a/v implementation better than the old mpg1 will be welcomed.

-ability to fast load all vids, also if incomplete.
-to play the movie also if you only have a little chunk of it starting at whatever position(not all the mpg are so,but could easy be)

another good new im thinking about,beyond the variable frame rate,
is a VARIABLE SCREEN SIZE,
that is the video is encoded at different resolutions in different parts(es. 640x352, and then,say,384x576).
Would be also cool to have different shapes than rectangular,like elliptycal.

On the MFC page is mentioned the player support problem,
but still more important will be the editors support problem.
since if would be easy to build a dedicated player when wmp wont support the new format, will be impossible to build big programs like ulead or premiere.

what i can think now is a "plugin" that makes possible to present editors to load the movie,
or to write a new mpg1 or avi driver that supports the new format with the olds,
making possible to "normal" applications to read it.

If avi sucks, let us drop it.

@movmasty


i´m not that experienced in video formats but i think, that your suggestions would requiere more some kind of "zip container" for the data, expecially when it goes to different resolutions for the different parts of a movie....

and the eliptic shape for the movie, is more or less unuseful, i think...


actron :sly:

MCF will

- play even corupted streams, thanks to Adler32 correction and many other safety features
- provide the capability to use different aspect ratios for one movie, but not for different parts of the movie. I am not sure if this is feasible at all, no idea how long it takes to switch res in the video renderer from one frame to the next ?
- be implemented in Vdub if we are successfull in creating libraries that Avery Lee likes ( he was posting recently at our board again )
- play in any Mediaplayer, even in WMP, thanks to DirectShow

[movmasty]

but Vdub doesnt supports non linear editing(for now)
and Lee cant build alone a free prog will all the functions of ulead.
but ok, if the new format will have success editors will support it, sometime...

about the variable screen size i dont think will be very difficult to do, just as switch to another movie with the player.

now a question, which are the causes of the amazing behaviour of mpg video streams over avis?
how differnt is the file formed?
and, what is the url of your board ??

@Actron
not more than rectangular...., well maybe video enthusiast will like it.
anyone know of some program that displays circular windows?
