Problem again :cry: :cry: :cry: plz. HELP :cry: :cry: :cry:

When I open my virtualdub and open my vid .avi file window pop up and say like this
Alert Window *VBR audio stream detected*
*?*
VirtualDub has detected an improper VBR audio encoding in the source AVI file (audio stream 1).
The current preference is to rewrite the audio header with standard CBR values during processing for better compatibility. This may introduce up to 26 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 bitrate encoder. (bitrate: 128.0 = 0.5 kbps)


Do you still want to rewrite the header?

[YES] [NO]
So what's should I do? :? :? :? :? and also I read the Glossary am I rite in that link yeah? :? :? but still I'm confused. Plz HELP !!! :cry: :cry: I will not close my virtual or even touching it to be sure I did not mess anything :cry: :cry: :cry:

:( :( :( YES ~.~ errr..... but moonnie told me to click NO so I did and this pop up another window for me :cry: :cry: :cry:
Coun't locate decompressor for format "DIV3" (Microsoft High-Speed MPEG-4 V3 [Hack: DviX Low Motion])
VirtualDub requires a Video for Windows (VFW) compatible codec to decompress video. DirectShow codecs, such as those used by Window Media Player, are not suitable. Only 'Direct stream copy' is available for this video.


[OK]
I did what Scintilla told me to download and install the XviD in my laptop and also he say that I will not having problem to open my file but it did happen again :? :? :cry: :cry:

Beside it happen this to me before when someone told me to use vdub after he help me something he leave me like in nowhere and confusing in this thingy so so tell me what I should do in this VdubMod to open and play the video file :? :? :? :? :?

regarding your audio problem.
the avi container does not really support vbr (variable bit rate) audio streams. (you can do it, but it's not advised. This is what's known as a "hack")

there are a few ways to deal with this (the best options use programs other than virtualdub), but I don't have the time to go through them.

as for the div3 thing...this is what fourcc.org has to say:
low motion codec (optimised for low motion source material?). Several sources tell me that this is an old and illegal codec that should not be used to encode new material.

the warning message that vdub gives you even tells you that it's a hack.

looks like it's still divx though. the link the site gives

I said you wouldn't have problems with <b>XviD</b>-encoded AVIs; I said nothing about any other codecs. :P

This message is for a different FourCC (DIV3 instead of XVID), so it requires a different codec -- DivX 3.11 Alpha ";-)", which you can get here:

:cry: ok and there's so many code I need to install in my laptop to make amv is there anything "One Codec" to be install in my PC than to get 'em all just to work my vdub/mod *sigh* :oops: :oops: :oops: :oops:

sorry but ok I will get that also :oops: :oops: :cry: :cry: :oops: :oops: :oops:

Well, I had the same problem when I tried to open some AVIs with VirtualDub, and, after several days of searching and trying, I finally found the ONLY 100% EFFECTIVE SOLUTION. That stuff about decompressing and recompressing doesn’t work: after the whole process it loses sync between video and audio.
First of all, let’s understand the problem:
You have an AVI file which’s audio is encoded with VBR (Variable Bit Rate). This is very frequently used, but is not “technically correct” for AVI files. VirtualDub suggests decompressing the audio and recompressing it with CBR (Constant Bit Rate). This, no matter which way you do it, which program you use, which BitRate you choose, won’t work. You will never get sync between Audio and Video.
There’s a program called VirtualDubMod. It’s a variation of VirtualDub, with a lot of great add-ons, but still has this same problem: can’t handle files with VBR without losing sync. There’s another program called NanDub. It’s another variation of VirtualDub specially designed to work with files with VBR. It doesn’t alert anything when you open the file. The problem is that it just doesn’t work: when trying to save the file, although you’ve already selected the desired compression, it doesn’t compress anything and writes entire raw video data. This generates a file of approximately 80 GB. Not to mention that IT DOESN’T WRITE ANY AUDIO DATA AT ALL. Maybe it’s my fault, but it’s a lot different and harder to use than VirtualDub. Searching a lot more, I discovered that an earlier version of VirtualDubMod (the first variation I mentioned) has a checkbox in the lower left corner of the “Open Video File” dialogue that reads “NanDub VBR MP3 compatibility mode”. I can’t imagine why they left out this option in newer versions. So, to sum up, you need VirtualDubMod 1.4.11.2
Download it from http://downloads.sourceforge.net/virtua ... g_mirror=0
As you might have already guessed, problems don’t stop here: VirtualDubMod has always been distributed in two packages: one for the program files and another for the DLL files. And also, as an option, an “ALL INCLUSIVE” package, which includes both. But the problem is that they discontinued the DLL package as well as the “ALL INCLUSIVE” for older versions, so, if you download and install from the url I gave you, it won’t work yet. You need to get the DLLs from a newer version. Download it from http://downloads.sourceforge.net/virtua ... g_mirror=0
Now extract all files from the 1.4.11.2 version (the firs link) into a folder. Then, extract all DLL files from the 1.5.10.2 version (second link) to the same folder. MORE PROBLEMS: the older version uses some DLL files that the newer doesn’t, so you need to get them from somewhere else. These files are libpng.dll and zlib.dll.
You can get them from these addresses (these are the versions that work with this program, it took me a while to find them, because they are also older versions, and newer versions won’t work with VirtualDubMod 1.4.11.2, so don’t try getting them from other addresses):
libpng.dll: http://www.driverskit.net/dll/get/1722.html
zlib.dll: http://www.dll-files.com/dllindex/downl ... 0UIkR0dJgT
They are both within zip files, so you need to open the files you downloaded and extract both DLL files into VirtualDubMod folder.
Congratulations!!! You did it! Finally! Now, open VirtualDubMod, choose File>Open video file. Check the “NanDub VBR MP3 compatibility mode” checkbox before selecting the file, and then just open the file you want. You should know that you can’t change anything about the audio stream (compression, conversion, etc) or it will lose sync. Be sure that “Direct Stream Copy” is selected in the Audio menu. That’s it. You can do whatever you want to the video stream without losing sync in an AVI file with VBR audio encoding. It’s also possible that you won’t hear any audio when playing the opened video file in VirtualDubMod, but it will be perfect when you save it and open it with a Video Player such as Windows Media Player, DivX Player, or any other.
Hope it helps, I couldn’t find this solution anywhere, I had to discover it myself, so read this and you won’t have to go to so much trouble as I did. Greetings,

Gabriel
