MP4 volume? - Esato archive

Any programmes out there that can increase the loudness of MP4 Videos? I have some that dont play very loud at all on my 750i

I thought wavepad just dealt with audio files, not video?

There are no software that can simply increase volumes of mp4 videos.

A video usually has 2 streams, 1 videostream and 1 audiostream

To increase volume or otherwise alter the audiostream, you would first need to demux the video and audiostreams into 2 separate streams. Then alter the audiostream as you wish, and finally mux the new audiostream back together with the videostream.
