I have on my hard disk a movie in the form of VOB file. I would like to cause part of it (in this case the beginning)to sound louder. Is or are there any program/s (as fare as possible not too complicated one/s)with which one can do it ?
This uses a number of programs, but comprises simple steps.
The Video and Audio are separated;the audio adjusted;the new audio and original video are rejoined to create a new file.
1 VOBEDIT- DemuxVOB to m2v and ac3 2 PX3- Convert AC3 to WAV
3 Audacity- Load wav and adjust audio and output New WAV
4 FFMPEGGui- Convert New WAV to New AC3
5-MUXMAN- Mux m2v with New AC3 into New VOB (a New VOB folder with all the required files is created)
Run VobEdit > 'Open', select VTS_01_1.VOB (the first large VOB of the title, the rest will come in at the same time).
'Demux' > select 'All Video and Audio'.
The files will be saved as an .m2v and an ac3.
Drag or load the wav onto the window.
Highlight the section to amplify, click 'Effects'.
Choose 'Amplify'
Check 'Allow Clipping' and set the slider up ~9db, check the level then OK.
Play the stream to verify that the sound is good.
Export the file as 'new.wav'
The basic steps would be the same for MPEG files, inasmuch as it is demuxed, adjusted and remuxed.
Run 'Rejig', 'File' Mode.
Select the MPEG file then demux both streams to M2Vamd MP2 (MPA?)
Adjust/convert the audio.
Load new WAV and M2V into 'IMagoMPEG Muxer' and create new MPEG file.
For AVI, use VirtualDub.
Load video, then ('File' 'Save wav'), then reload the new wav ('Audio' 'WAV Audio').
Note, you would have to select a compression for the new audio, else it is saved as a large, uncompressed PCM file.
Save the new video file without recompressing ('Video' 'Direct Stream Copy).
