Audio out of sync (with over 0.5sec) when joining multiple avi files

[andy_blah]

I`ve been using BoilSoft Video Joiner and I`m still having this problem. I am trying to join 10 avi files of about 100MB each, XVid encoded 50FPS and the audio is Lame MP3 192kbps CBR. I`ve also tried Easy Video Joiner but it has a problem, starting from the 2nd joined video, I cannot hear any sound (this happens to any kind of avi file I try to join. I would like to know if there is any solution to my problem.

[45tripp]

try vdub

[andy_blah]

How can I join video files in VritualDub?

[guns1inger]

Load the first part, then click on File -> Append to add extra parts.

Personally I find AVI Demux more reliable than Vdub, especially if the audio is VBR MP3.

If you use Vdub, use the latest version, and use smart rendering for the join.

[andy_blah]

Thank-you, now I`ve got my problem solved

[andy_blah]

I can`t believe it, the problem is back now, just that it`s MUCH more worse!
I did the same thing, appended all the video files that I needed. I check the final video file and find out that after the half of the video the sound gets choppy! I`ve tried to open it, and append the rest with VirtualDub but it says:
"Cannot append segment '*path to file*': The audio streams have incompatible data formats. (Mismatch detected in opaque codec data at byte 20 of the format data)

I did not apply a different method than the one that I used before (for DVD ripping, splitting, etc.) and used the same quality rates!

[guns1inger]

Have you tried AVI Demux ?

[andy_blah]

Erm, if you would look by four posts above you would see that you already suggested to me that, so that results naturally that I used it this time before trying VirtualDub...

Actually, I rarely assume that anyone has tried anything suggested unless they specifically say so. You have only mentioned problems with virtualdub, and nothing regarding AVI Demux, hence my question.

So what happened when you tried AVI Demux ?

It might also be worth posting either mediainfo outputs or g-spot screen shots of the file sin question so we can see what you are working with.

[45tripp]

in any case,

i'd take each section,
direct stream copy video, audio to full uncompress,
then
append,
direct stream copy video, compress audio

[andy_blah]

You mean as in export the audio of the source files to wav, join them, and after that to add them to Section1.avi?

[45tripp]

no i mean create section1new.avi with uncompressed audio,
an so on...
then append sectionnew.avi files, and when exporting recompress audio.

[andy_blah]

I must tell you that this section1.avi was done in AviDemux, not in VirtualDub. If you will read above you would see why. And section1.avi has that audio problem in it already, recompressing the audio won`t do any good.

[45tripp]

If you will read above you would see why.

i tend to read before posting
you've not written it.

I am trying to join 10 avi files of about 100MB each, XVid encoded 50FPS and the audio is Lame MP3 192kbps CBR.

"Cannot append segment '*path to file*': The audio streams have incompatible data formats. (Mismatch detected in opaque codec data at byte 20 of the format data)

maybe you want to be more specific about what you are doing,
what you did,
what failed,
how it failed.

if you;re running a mishmash approach,
no one will follow.

And section1.avi has that audio problem in it already, recompressing the audio won`t do any good.

if it's already evident in step 0,
how'd you expect to correctly append?

and again if step 0 is problematic,
trying to go to uncompressed, is a sound idea,
unless the audio is damaged and beyond salvage,
in which case, quit.

tripp

[andy_blah]

Ok then, I will have no choice, just to repeat myself *sigh*

What I used last time, and it worked (on joining): AviDemux
What I used this time, and failed: AviDemux - problem: audio is choppy after the second half of the video
What I tried to use further: VirtualDub - failed - message after appending different avi segments: "Cannot append segment '*path to file*': The audio streams have incompatible data formats. (Mismatch detected in opaque codec data at byte 20 of the format data) <- and this was the reason of not using VirtualDub for appending avi segments

I cannot understand what you mean by all the "uncompressed". Maybe if you would tell me in which program I should do that and precisely how to do it.

Might be a stupid question, but what do you mean by "Step 0"?

[45tripp]

Might be a stupid question, but what do you mean by "Step 0"?

you seem to imply with this:

And section1.avi has that audio problem in it already, recompressing the audio won`t do any good.

that section1 already has problematic audio,
before even attempting to append, hence you'd need to see to that before attempting appendage.
so i dubbed it step 0.

I cannot understand what you mean by all the "uncompressed". Maybe if you would tell me in which program I should do that and precisely how to do it.

open section1 in vdub.
set 'video' ->'direct stream copy'
set 'audio' ->'full processing mode'
'save as' section1new.avi
repeat for section2, section3,....

open section1new.avi,
append section2new, section3new,....
set 'video' ->'direct stream copy'
set 'audio' ->'full processing mode' & set 'compression' to lame mp3.
save avi.

try appending in avidemux as well.

you could also try to disable audio and mux video only,
demux each audio to full uncompressed .wav, and use an audio editor to work at it,
compress and mux.

they might not be appendable, in which case you have to join in avisynth reencode everything.

the audio might be buggered,
in which case good luck.

and when gunslinger said post info,
he meant a grab on at least 2 of the streams you plan to append,
to compare their properties.

[andy_blah]

I`ve done that uncompressed audio method you suggested me to, but it still says: "Error Initializing audio stream decompression:
No installed audio codec could be found to decompress the compressed source audio." But I do have that specific codec (which is Lame MP3)

Here is some information about two of the videos that I`ve been trying to join:

[andy_blah]

I don`t understand what you mean

[poisondeathray]

You need lame acm for the vdub method suggested earlier, lame mp3 by itself is insufficient

[andy_blah]

But I do have that specific codec (which is Lame MP3)

v.v"

[45tripp]

I don`t understand what you mean

he means upload (to rapidshare yes, mediafire better), only the mp3 streams of the 2 files you
posted info on.
that's a total of 5mb only,
demux the audio from each file.

and poisondeathray means to double check,
can you uncompress any mp3 file in vdub?
is it failing only on these files?


and my methodology still stands.
change the tools until something works,
or until nothing works.
but the method is the same.
ie start trying the process in avidemux

[andy_blah]

Here it is: http://rapidshare.com/files/136339040/mp3s.zip.html (I prefer uploading to Rapidshare, sorry)

I was going over the splitted videos and I observed that some were at 128, some at 192, can this be one of the causes?

What process should I start in Avidemux?

of course

Here it is: http://rapidshare.com/files/136339040/mp3s.zip.html (I prefer uploading to Rapidshare, sorry)

nothing wrong with the attached mp3s,
they join fine too.

lame acm, for vdub
as poisondeathray mentioned, ( http://www.rarewares.org/mp3-lame-dshow-acm.php )

What process should I start in Avidemux?

https://forum.videohelp.com/topic354272.html#1876438
mp3->uncompressed audio,
then join, then recompress audio.
(plus fallback solutions)


tripp

[Midzuki]

Okay, I downloaded the .mp3s, removed their .WAV headers,
played them finely in both MPC and Winamp,
hexviewed them with XVI32, no problems were detected.

I was going over the splitted videos and I observed that some were at 128,
some at 192, can this be one of the causes?

What do you think

[andy_blah]

I suppose that I should try to cut again from the source, *sigh*
