VirutalDub Problem!!!

[davidcws2000]

I trying to convert the audio file form an AVI file to WAV. But once i open a anime file and a message pop out and said this :

'VirtualDub has detected an improper VBR audio encoding in the source AVI file and will rewrite the audio header with standard CBR valves during processing for better compatibility. This may introduce up to 7502 ms of skew from the video stream. If this is unacceptable, decompress the *entire* audio stream to an uncompressed WAV file and recompress with a constant birate encoder. (birate 145.0?18.3kbps)'

I have no idea what it's mean. I'm trying to convert an AVI file to MPEG so i need to convert the audio to wav. Any idea what the what's the problem is.

By the way, I think the problem (I'm not sure ) is with my file because went i watch the movie, the sound (the speech and the music) run faster than the movie goes. Any idea that i can fix this problem.

Thanks in advances

VDUb is telling you to save the audio as a wav since it can't handle it the way it is.

The wav should fine without adjustment for use in TMPGenc or other encoder.

Thanks snowmoon, but is there any way that i can change back the audio to the right position because the sound seems to be faster the the movie goes (and sometimes slower)? Please advise

What are you playing the avi with that gives this problem? If Virtualdub, it's because It doesn't like VBR audio, as was pointed out already. If you extract the uncompressed wav then you should have no problem converting to a correctly-synced mpeg. If you still get problems, then either the source avi is not in sync, or there are errors with the video stream. If you just want to play the avi, then use something else other than Virtualdub!

you must correct the audio this way. go into vdub load file. then in audio check full processing mode. then in audio check conversion and choose 44100, 16 bit, stereo, high quality. then either save this wav of add the video with direct stream copy and save the entire avi. it will play in sync then. i guarantee that if you open this file and check full processing and then conversion it will tell you that the file is 8 bit, and probably 48000. this is your problem.

[davidcws2000]

KingJohn, not that i have not go through the guide's, I have print out a lot of guide's and i follow the guide to during the process. I'm still new with this site and i have try to seach but no result This is why, i try on this forum for the newbie which have problems and get help from the professionals I hope my question does not bored you and i know some of them sound stupid but thats my problem i'm facing. Hope you understand....

[banjazzer]

KingJohn has a valid point. So many people now ask questions before even bothering to look at the CONVERT section to the left, or the User guides at the bottom of this forum.

Hi

No I never get board with answering the same questions over and over "and over" Its just that I seen so many posts from you in a short period of time, with so many problems, that I felt you needed to read the guide's

The error you are getting in Virtual Dub is normal for an AVI which has VBR, you ask also about saving out the audio as a WAV, however you kill all the replies to that, because you say the original is not playing correctly.

Maybe the first problem.
KingJohns Guide to bad frames

However, if your original has lip sync to start with, and has VBR. You may need to decompress the Video as well as the audio, before you can fix the problem.

So I think you need to post again starting at the beginning, and the first problem you have, no point in moving on to other things if the AVI is not playing correctly.
