I've just bought a DVD which is recorded quite softly. It was for my mother who is quite deaf and wears two hearing aids and has the volume up a fair bit. This DVD just won't go loud enough. Considering it's got a fair bit of music in it, subtitles are not the whole answer. I've been looking around for how to raise the volume and can only come up with - demux video/audio, convert AC3 audio to WAV, use Audacity to raise volume convert WAV to AC3 remux video/audio streams re-author VOB/IFO files together It's a bit of a journey with eleven VOB files to process. Does anybody know of an editing application that will take the whole movie and batch these operations into a single pass?
When you rip the audio with 'Rejig' (IFO mode),it rips all the VOB's automatically and puts out a single WAV. 'AC3Tool' will convert AC3 to WAV, then you use Audacity. 'FFMpeg' will convert the new WAV to a new AC3 and 'Rejig' (DVD Author) will remux.
Thanks Attar, I will check out Rejig. ATM I am looking over VideoReDo to see if it will do what I'm looking for.
