Bulk/Mass Edit Video Audio? I have 100 videos that need editing so that I can level the and amplify the audio track. However I do not want to have to extract the mp3 track from each one and edit it then merge it again with the video. this is aloooonggg process.

Is there a software that can achieve this or something similar?
you can use avconv (the ffmpeg utility replacement) and mp3gain to script extracting, adjusting and merging the files.

The advantage using mp3gain is that it does not reencode the audio but just adjust levels. So you don't lose any quality. It has a nice automatic mode that work descent although not perfect.
