put nero avc into avi

[SimonSez07]

trying to extract avc video from nero mp4 file and put into avi. tried using mp4box, but it outputs unusable avi (virtualdub says resolution 0x0).

extracted raw h264 (using both mp4box and mp4creator) but then avc2avi crashes when using this raw file.

anyone know a way to do this successfully?

why do you want to put avc in avi?

[guada 2]

"Who knows", Maybe a question of compatibility.

Why you do not use Nero 7 to make conversion?

[SimonSez07]

to open in virtualdub. and to use vfw decompressor to decode (as in avisynth: avisource). and for comparison with x264 avis i have encoded. plus if i distribute avi to another user that has ffdshow installed, they can play it without any mp4 split filters installed. and it wont open in quicktime or anything they dont want.

@guada 2 i did use nero 7 to encode file. are you saying nero will let me put avc in avi?

Have you tried it:

Photo and video / Capture video (annul) / to Create a movie (Browse, Following) / Export the movie (Following) / Personalize, AVI, Huffyuv2.1.1.

I think that it functions.

[SimonSez07]

i think what you are doing is re-encoding the video into some avi file. but i tried anyway. i went into photo and video / capture video and then it said "no supported capture device"

i have a file "movie.mp4" encoded with nero avc standard profile using recode. i am trying to extract the video track (track 3) to an avi file (fourcc h246) for use in virtual dub.

hope thats clearer. thanks for the help

Have you tried mp4UI (http://mp4ui.sourceforge.net/) ?

This little free program can demux your mp4 file and export the video part as an Avi which can then be loaded into virtualdubmod

For the audio you can use Nero Wave Editor to convert the aac to ac3, mp3 or wav and again import that file in virtualdubmod (streams -->stream list)

Finally remux your audio and video (direct sream copy) in virtualdubmod ( http://virtualdubmod.sourceforge.net/)

mp4UI can extract avc to an avi?

mp4UI can extract avc to an avi?No. mp4UI doesn't support AVC.plus if i distribute avi to another user that has ffdshow installed, they can play it without any mp4 split filters installed. and it wont open in quicktime or anything they dont want.Just give them the latest Media Player Classic instead, they can use ffdshow with that without installing any mp4 splitters. AVC in avi is not a good solution.

You're right, I misunderstood Simon's question. mp4Ui does support Nero Digital Mp4 ASP but not AVC. Sorry

SimonSez07,

Sorry, I had not understood your reasoning.
Nevertheless, my stept functions (AVC to AVI with nero 7 / make a short test, you will see).
But it is not your real problem.
It is true it doesn't have really utilitarian able to make your process.
You would probably need a " m2d mp4demuxer "or a "YAMB" with the option demux, to make well.

Who knows, maybe you will have the luck that a developer saves you the stake.
it will be very interesting for you like everybody else. :)

Bye.

AVC in avi is not a good solution.

Ahem... And no arguments as usual :D An avc in .avi is same if not more compatible
than .mp4, not to mention it is way more flexible in terms of editing. I know, you'll say
that there's some bframes glitch, etc... Funny thing is, that avc plays perfectly even with
no bframes presented at all.

AVC wasn't standardised for avi.
Using water instead of gasoline isn't standartised either. Though, noone would argue
which is better.

It won't work optimally in avi.

Tell me exactly why. Please.

You can't use all the advanced features of AVC in avi. Same thing with SP/ASP (VFR for example).

What advanced feats..? What SP/ASP have to do with it? And who really needs VFR in video stream? How is it superior to CFR???

Before I even opened this thread, I guessed that several of the replies would be along the lines of "don't do it" and "AVI sucks". Why do these evangelistic replies not surprise me?

H.264 spec does not tell anyone what container or systems layer they should use. AVI is a perfectly good container for constant framerate, one-in-one-out decoding.

Sorry I can't help much with the original question: I could write some code to do it, but I'm a software consultant so time==$$$ ;). It would be possible to write a driver for the VfW subsystem that allows any application which uses Windows API calls to load AVI files to also open .mp4's...... an interesting project for sure, not sure if anyone has done this yet.
