Audio Fad In/Fade Out

[Killer 69]

Pls. add this, would make a big difference

"I'm pretty sure fade outs did not occur during the days when 78s were used ... since in those days music was recorded directly to disc. Once studios started using magnetic tape for their masters (early-mid 1950s)

Barbra, I agree the audio editing is very limited in avidemux. But there is a simple enough work around that should fit your needs.

First, make note of the frames you want to fade (audio and video will both fade in). Then, open avisynth proxy, select custom tab. Next is a little script writing. Define the source [if it is an .avi] type in the text box:

Code: [Select]

avisource("C:\pathtofile.avi")
FadeIn(2000) #This fades in until frame 2000.
Here's some documentation if you have trouble understanding the fade parameter. You can find more documentation on the avisynth wiki.

Hope that helps

After thinking about it, there is a much better alternate way to do this.

Use an external audio editor, such as Audacity, then use external source for the audio track.
