Virtualdub's default MP3 encoder sometimes doesn't have any viable outputs. Why?

Note that this isn't related to number of channels, sample rate, or anything like that. The audio in question works just fine with LAME mp3 at the same settings that would normally be available to Vdub's own mp3.

If previously I select: Audio -> Full processing mode.

I can Save audio... to valid mp3 with VirtualDub2 v2.1.1.607 like show in the image.

The same with VirtualDub2 Build 44282 64 or 32 bits.

Okay but I'm not talking about Virtualdub2. I'm talking about normal Virtualdub.

AFAIK (or remember), the original VirtualDub does NOT have "its own" MP3 encoder, it uses (by default) the crippled MP3 codec licensed to Microsoft by Fraunhofer :-|
If you don't like LAME's ACM, you can replace the crippled Fraunhofer codec by its fully-functional "professional" edition
(l3codecp.acm)

Or read the info about lameACM.acm in RareWares
Maybe for that are not "viables" for you.

Also in RareWares l3codecp.acm

That's irrelevant hair-splitting. The MP3 encoder that ships with Virtualdub sometimes doesn't offer any output settings and I'd like to know why and how to fix it.

You need install ACM encoders.
In my W10 SO only some Windows compression can be used.

To read my test.avi (xVid+AC3) I need use AviSynth decoders because I haven't VFW decoders installed.

Any problem with VirtualDub2?

That was true in the earlier versions of it. The current version, however, does have it. I was quite thrilled by that because it meant that I no longer had to remember where to get LAME or how to install it

Are you referring to Avery Lee's last version from 2013? As far as I understand and remember, classic VirtualDub never had a concept of built-in encoders; it was always the ACM ones from Windows. Also, from a quality point of view, using any MP3 encoder other than LAME is not advisable (though I believe Helix has the edge).

If you're looking for a range of encoders and decoders in one executable, FFmpeg is brilliant.

I used the final version 1.10.4 from 2013, what version do you have?
I try a last test 1.10.5 (2014) version in https://www.videohelp.com/software/Virtualdub , and still without internal MP3 encoder, only decoder.

I put the link to rarewares, to install it use the .inf file, or the HOWTO Install LAME-ACM on x64.txt
