I have to use windows at work. I have already installed various GNUWin32 packages. I have many of the classic cross-platform #opensource programs (firefox, vlc, libreoffice, eclipse, ffmpeg, python, etc etc).
Now this: a #package #manager for #windows. From command line.
If only I could manage to run Sony Vegas on Linux, my life would be easier
I have bunch of #mp4 #video files with low volume #audio.
How I can turn it up with minimum loss?
With #ffmpeg, #sox, #mp4box to interleave for streaming.
Here the bat (yes, for #windows ..) (modified from this)
echo off echo Extracting audio.. ffmpeg.exe -i %1 -ac 2 -y %1_clean.wav echo Extracting video.. ffmpeg.exe -i %1 -map 0:0 -vcodec copy -y %1_clean.mp4 echo Normalizing and compressing audio.. sox.exe --show-progress --norm %1_clean.wav %1_norm.wav compand 0.3,1 6:-70,-60,-20 -5 -90 0.2 echo Creating new video file.. ffmpeg.exe -i %1_clean.mp4 -i %1_norm.wav -vcodec copy -b:a 96k -ac 1 %1_norm.mp4 MP4Box.exe -i 500 %1_norm.mp4 echo Cleaning.. del %1_clean.wav del %1_clean.mp4 del %1_norm.wav
The video is untouched, but the audio is recompressed. It will loss a bit.
My script compress audio to 96kbps mono, but if replace "-b:a 96k -ac 1" with "-b:a 128k -ac 2", you will get a 128kbps stereo, much better
