Portable BOX4 Video Remuxer v3.0 Final (x64)
BOX4 portable is a MKV/MP4/MOV/FLV to MKV/MP4 re-packager/remuxer/converter. It is an update to the old rebox.NET which needed refreshing simply because it was a little limited and concentrated too much on outputting to consoles. BOX4 now outputs to both MKV and MP4 using MP3, AAC and AC3 audio codec options. It also uses the audio filter ‘Dynamic Audio Normalizer’ which simply, is amazing.
