I have a collection of mp4 movie files and a lot of them have audio that is too high in some places and low in others. I found a small program called MP4gain that I thought would be perfect because it could normalize the audio of a 90min mp4 movie file and save it in about 1 min and the bonus was it could do files in batch. Only problem was the audio of many files would get cut off about midway through the movies.
Is there a program other than MP4gain that I can import an mp4 file run a normalize filter on the audio and save the file without it taking upwards of an hour or more to re encode? It's possible because mp4gain can do it but that program tends to cut off the audio about midway.
