what kind of audio ?

[natty]

its just a .avi movie i didnt mean i made the movie. i dont understand what u mean when u say what audio, I just thought there is only 1 kind or maybe i am wrong

Many types of AVI. AVI is just a container name. It can be Xvid or Quicktime or DV or others. The audio format is similar. Common ones are MP3 or AC3 or less common, ogg vorbis. There are many more

Drop your video into Gspot, it will tell you the codecs used for the video and audio and those are what is important, not the video type. Post the screenshot here. Blank out the title if you like.

Usually VirtualDub doesn't do anything with your audio, unless you tell it to.

how do you set up audio in virtualdub anyway

here is a snap of movie

[jimmalenko]

What are you trying to do ?

[natty]

i am trying to enhance video and also audio i was told to send snap of movie

[Cornucopia]

What kind of "enhancement" do you think it's needing?

Volume boost?
Dynamic Range Squeeze?
Background Noise Reduction?
Hiss Filtering?
Pop/Tick Removal?
Vocal Separation/Removal?
Remix/Rebalance of the various Dialog/FX/Music Parts?
undo of mp3 compression artifacts?

There are all kinds of ways to enhance an audio clip. Some of those listed above are easy to do, some are pretty near IMPOSSIBLE.

Volume boost

[Cornucopia]

Do this:

(Old AVI) --> Demux (AVIDemux) = XvidVideoOnly.AVI + AudioOnly.mp3
Do what you need to do with Video...
Open AudioOnly.mp3 in MP3Gain or Mp3DirectCut and "Normalize" (or the equivalent). Save to FixedAudioOnly.mp3. Won't even re-encode!
Remux with video (use VirtualDub or AVIMuxGui, etc)

I'm not sure which version of VD you are using, but in general: Select 'Full Processing' under 'Audio' and a volume control selection will come up. Adjust the volume here, and then in 'Compression', select a MP3 compression setting that is similar to what the original is. In Video, select 'Direct Stream Copy' and save the old video with the new audio.

Or if you want to do a little more with the audio, save it out as a WAV and process it with a audio editor like Audacity. It's freeware and has a lot of filters. Then save it out as a WAV again and use VD to encode it back to MP3 and combine it with your video, then save as above.

Other versions of VD have slightly different methods. In 'Tools' on the VirtualDub page, there is a listing of guides to the bottom. <<<<<<

I am using virtualdub v1.6.13 and nothing happens when i do the above no volume control selection pops up

[Cornucopia]

Something might be amiss with your copy of Virtualdub.

Nevertheless, you may not want to do it that way. It will RE-encode your audio (or just decode it to WAV = larger size). That's why I suggested what I did, NO RE-ENCODING.

I'm pretty sure that it literally won't "pop up" - he means that it will stop from being greyed out and will now be accessible from the Audio menu.
