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 and AAC audio codec options. It also uses the audio filter ‘Dynamic Audio Normalizer’ which simply, is amazing.

The Dynamic Audio Normalizer is like a Dynamic Range Compressor AND Normalizer WITH intelligence ALL IN ONE.
I was fed up messing around with different ‘compand|pan’ filter options or manually altering channel levels (rebox.NET) so I was rather excited when I stumbled across this little tool. It was exactly what I wanted and I use it exclusively. Basically it performs D.R.C and normalizes the audio in an intelligent way to give you what many people ask for: A ‘Night Mode’. An audio track that is far more consistent in terms of volume across the range resulting in you not having to keep changing the volume throughout. I use this filter on all the movies I do for my daughter, no more constant volume changing.
INPUT|OUTPUT folders are independent and remembered between jobs and sessions.
BITMAP subtitles will not be taken into MP4 files, even if selected.
Only one AUDIO|SUBTITLE track can be selected (currently).
Your input file must contain a H264 VIDEO stream and at least one AUDIO stream.
BOX4 is x64 ONLY, it will not work on 32-BIT computers.
BOX4 has only been tested on WINDOWS 10 (developed) and WINDOWS 7.
BOX4 is a .NET application and requires .NET Framework v4.5.2 or greater (included in this portable).
