WMA Audio In VDubMod?

[Yo]

I recently discovered the WMV-VCM video codec (you can find it with a search at Microsoft.com), with which you can use WMV9 video compression in any program in any container. Therefore, in using it in Vdub or Vdubmod, one can create an AVI, OGM, or Matroska file using WMV9 as the compression codec.

I created a movie with that, and thought while using WMV as the video codec, I might as well use WMA as the audio codec. (Although that's not a requirement. You can use any audio codec with it.)

If under audio settings you choose "Full Stream Compression", then choose "Compression", and see the codecs to choose from, I don't see any that I think are WMA9. There are two that could be: one says "Windows Media Audio V1", and the other "Windows Media Audio V2". What are those? Are either the same as WMA9?

If I choose one of those two, however, I do not see any formats to choose from on the right hand side. If I click "Show All Formats", then I see some. But why do they not show up right away? Are they considered incompatible?

If I go ahead and choose one of those formats that came up when I clicked "Show all Formats", a problem arises at the final stage, when I try to save the video. The encoding doesn't really start-- right after clicking on "Save" the process stops with an error message:

"Error initializing audio stream compression, the requested conversion is not possible."

I guess that might have something to do with the fact that when one first clicks on either of the WMA codecs shown, no formats appear on the right side, until one clicks "Show all Formats".

Is there a way to use current WMA audio compression in a movie created by VirtualDub, or VirtualDubMod? (Perhaps something similar to the WMV-VCM video codec, for audio?)

Do any of the audio transcoders for video, such as BeSweet, support WMA audio?

If I were to convert the stream to WMA in another audio converter, such as DBPowerAmp, would I be able to mux that WMA file with the movie in Vdub (VdubMod)?

Thank you in advance for your input.

dont do it, if you want WMV with WMA, either use WMEnconder, or encode the video with VirtualDub and the audio separatly (perhaps with WMencoder too, i dunno) and mux them in Matroska.

for your answer to perhaps get the WMA codecs in VD working:

go to audio-->conversion (in VDM you can find conversion when you right-click on the audio-stream) and fill in the right conversion factors for the audio.

So, are you saying that a Matroska program will mux an WMA file with a video? What is the name of the program?

In the last paragraph, do you mean that if, for instance, the input video is a MPEG-2 file (so both video and audio are MPEG-2), and one is going to compress the video to AVI, OGM, or Matroska using the WMV-VCM codec, that if one wants to use WMA compression on the audio, rather than choosing "Compression" after right-clicking on the audio stream and choosing "Full Compression", choose "Conversion", and that will work?

MKVtoolnix probably will, graphedit also. note that you also have to download the matroska playback packs or a player that by default is able to play matroska files (e.g. MPC) for playback.

not really, look at the audio compression you have chosen in the compression menu, it will show things like channels (e.g. mono, stereo) and sampling frequency (e.g. 48 kHz). make sure that those things are the same in the conversion menu.

as a side note, im putting question marks at the quality you would obtain from those audio codecs.

So, as I first suspected, the WMA V1 and V2 codecs listed in the compression menu for audio (but with no formats shown until you click "show all formats"), is not really the same as WMA9 compression?

[stephanV]

not the same at all
