How can I increase the audio-volume of a movie ?

How can I turn up the volume-level of a movie before encoding, being allready low originally ?

I was just searching the forum and found something like the use of Besweet and resetting of ac3-filters, which are all parts of enoding-processes other than rebuilder that I'm not into.

u can't change the audio when using dvd rebuilder (at the moment ;)), u would have to do it before and reauthour then run through rebuilder, or use the big3 method.

and to make it louder u could try and normalize the audio and re-encode it... i think headac3he and softencode would work well for that

have you tried adding "AmplifydB" into the AVS script? see also

The audio isn't processed by AVS. The original audio is muxed with the new video at rebuild. It isn't even demuxed to a seperate file, but read directly from the source VOBs, which is why it is so difficult to tinker with and requires reauthoring before or after DVD-RB. Though if you are reauthoring then, why not just re-encode the video and skip DVD-RB all together.

Allow me to share this:

i got a few dvd which the audio track is LPCM,(original not compressed),
the size of the LPCM audio of the main movie is over 1GB, and all other audio track in bonus material was also LPCM, it make re-encode the full disc impossible (the result was not watchable, even using RB_CCE).
and i want to keep the original menu.

the way i fixed the audio is,
- i use 'Add DVD Video' in TMPGEnc DVD Author, select the 'Title'
that i want to do the audio re-encode (need to have TMPGEnc.DVD.Author.Sound.Plugin.AC-3 installed),and keep the chapter information, and output as a final dvd (playable video_ts)

- after that, i run DVDReMake, input the original video_ts (with LPCM audio track),
i locate the main movie in DVDReMake and replace each chapter with the one that TMPGEnc DVD Author created (audio re-encode to AC3 2.0), than i export the dvd.

- i run ifoedit
1.open the VIDEO_TS.IFO, locate the title that had the new ac3 track, change the audio to AC3 (DRC) (double click), save & replace the new VIDEO_TS.IFO with the original one.

2.again, open the VTS_??_?.IFO (the one had a new ac3 track), change the audio to AC3 (DRC), save & replace the new VTS_??_?.IFO with the original one.
* i also do 'Menu Extra' in ifoedit and replace VIDEO_TS.VOB with the original one), i didnt know it matter anything or not, but i have not problem with the new final 'video_ts'

- i test the new 'video_ts' in windvd to make sure it work.
- finally i run RB to run the encoding.

*The final copy work perfectly in my SA and pc with new ac3 audio track instead of the uncompressed LPCM
*This reduced over 1GB size of the original disc (before re-encoding with RB), and allow the video to be encode in a higher bitrate.
