How can I change the sound level of YouTube videos with minimal recoding.

[MarcMiller]

Hello
in another thread I read on these forums a question was asked on how to change the sound level on MP4 videos with minimal recoding. I essentially have the same question but my sources MP4 downloads from YouTube. There is a playlist of YouTube videos I wish to listen to again and again but one of them is much too loud. In this other thread the responder was suggesting the thread starter use mediacoder freeware and I have been trying that. The trouble is I go to the sound tab and pull down the slider to reduce the volume, but recoded file output is still at the same sound level of the original. Are there any tricks or other software I may use? Any ideas will be greatly appreciated.

Try Handbrake, the audio tab also has volume controls.
