Utility to boost audio level in Xvid file?

[StratPlaya]

Hello,

Anyone know of a utility that can boost the audio dB level in an MP4 type video file while leaving the video untouched?

Thanks,
SP

mp3DirectCut or mpTrim may work for that.

I tried MP3directcut but it only works on audio files.

Sorry, those were audio only programs.

Here's a link to a guide for normalizing audio for AVIs: https://forum.videohelp.com/topic314909.html

I would try this ( hope i explain it correctly )

use super to do an audio only file, use the volume increase option

use avidemux2 to add the new audio stream as a second stream, then delete the first stream and export/process /save the file , with video 'stream copy' on

you get a new avi with the original video stream and the new audio stream

SUPER is unnecessary.
You can use gain filter in Avidemux.

AVI or MP4?

i have read posts, in this very forum about the gain filter causing the sound to go out of sync with the video

but he can try it

I can modify the Avi_Gain batch file to work with MP4 containers, but I'm in a bit of a lazy mood. I'll do it if you're modifying more than 1 file,

Thanks to all for taking the time to reply.

FYI: the file is Xvid which I believe is considered an MP4 container.

I'll play around with AVIdemux to see how that works.

Will report back in a couple of days.

xvid is a codec, mp4 is the container, what is the file ext, mp4, mkv, 3g2

those are containers

AVIDemux2 worked great. I was able to down convert the audio on my 6 channel AC3 Xvid AVI video file to a simple stereo boosted by about 1 dB. I then saved the file normally and the old audio track was replaced by the new audio track on the AVI video file.

Thanks,
