audio problem please help

[thegrizz]

i am trying to convert an avi to mpg but i am having problems with the audio,avi plays great in wmp.but says unknown format in properties for the audio,ideas how to find out which format its in and best way to convert to wav.thanks in advance

[setarip]

Load the file into VirtualDub. then, from the "File" dropdown menu, select "File Information".

Post everything listed.

I'll bet you a tuppence (remember those?) that the audio is either .AC3 ("tag 2000") or VBR (variable bit rate)-MP3 (the audio file will be between 1.5 and 2 times as long as the video file)...

[thegrizz]

I knew I could rely on you m8,file info as follows,
sample rate=48000hz
channels=5(sterio)
compression=unknown(tag2000)
preload skew=28000 samples(0.58s)
#of frames=207455
min/avg/max/total.frame size =2083/2335/28000/4732111k

ps, i think i can just about remember farthings


regards

"compression=unknown(tag2000)" = .AC3 audio format.

You now are indebted to me for the princely sum of tuppence ;>}

In order to convert the audio to .WAV format, download both the specially modified VirtualDub v.1.4c-AC3 and the PX3AC3Converter.

Load the file into VirtualDub v.1.4c-AC3
From the "File" dropdown menu, select "Save as WAV"
Enter a new filename with an AC3 (".AC3") extender - This is critical!

Note: If you attempt to play this .AC3 file, it will not play properly, but have no fear.

If I'm correct in assuming that your intention is to eventually replicate the original .AVI but with WAV audio, do the following before exiting from VDub1.4c-AC3:

Change "Audio" to "No audio"
Change "Video" to "Direct Stream Copying"
Save your silent video with a new name and exit VDub v.1.4c-AC3

To create the .WAV audio file:
Load the .AC3 file into the PX3AC3Converter and convert it to a WAV file (which will play perfectly).

To merge your silent .AVI file with your .WAV audio file:

Open ANY version of VirtualDub
Load your silent .AVI file
From under the "Audio" dropdown menu, select "WAV audio"
Select your WAV audio file
Set both "Video" and "Audio" to "Direct Stream Copying"
Save your multiplexed .AVI with a new name

Let us know of your success ;>}

cheers m8y,your a star will let u know if I suceed and u were right in your assumption

[setarip]

"will let u know if I suceed"

What do you mean, "IF"? ;>}

[thegrizz]

I was right about the if.
question,were do I download that version of VDub v.1.4c-AC3,have tried the one from their official site? ie/v1.4c but cant find any reference to -AC3 and output from said version same as,even with the new file extention,
solution,I could just be thick,as I am still coming to terms with decimilisation never mind digital.

ps:I think i'll owe you tuppence ha'penny after this

As long as you don't try to fob off a Euro to me...

[thegrizz]

what can I say?your advice was spot on.I now have a perfect wave file.thanx again.

can you change a florin setarip ?

[setarip]

As always, my pleasure.

Into a kroner, perhaps ;>}

P.S. Do you think you could arrange for your bear gif to annihilate "Enchanter's" washerwoman?

[jbrice]

It seems the two of you should hop on top of a Grand Piano and do each other. I mean you're getting so cuddly. Is this a personals forum or a tech forum?

[setarip]

To jbrice

Although hardly worthy of a response:

Your remark is rude, crude, immature, and totally uncalled for.
Let's not get cranky, or profane, about some lighthearted humor.

If I choose to inject a liitle humor into posted responses that provide meaningful information to others (which may or may not have included you - something about converting widescreen to fullscreeen, if I remember correctly), that is, and always will be my prerogative.

I'd sincerely believe that an apology should be forthcoming from you, but if you don't agree that this is appropriate then I can only suggest that you limit your postings to:

A) technical matters

and

B) postings directed to you

[jbrice]

I will limit my responses to technical matters, and I'd appreciate only technical matters being posted.

[thegrizz]

setarip,whilst I appreciate the advice u give, I also enjoy a bit of witty humour,so feel free to carry on imparting both,as it must be sad to go though life without a sense of humour
