Remux Mp4

[danielmak]

I am looking for a program like Mkvtoolnix or TSMuxerGUI that will allow me to mux a new audio track into an existing Mp4 so the Mp4 will have multiple audio tracks. The previously mentioned programs are fast, have a graphic interface, and are easy to use with MKV and TS files respectively. I don't have to mess with any settings because the video is not altered (something I want to avoid with MP4 remuxing as well). I just want to be able to select another audio track that has already been edited to match the video. Can anyone recommend a program? My Google search leads me to a variety of programs but many seem to be old or don't have a graphic interface and I'm preferring to avoid downloading everything that pops up to then run tests when ideally I can rely on the knowledge of folks on this forum. Thanks.

Tried MyMp4boxGUI?

It's not as good as mkvmergegui but it's a gui at least(for Mp4box).


edit: I missed that you are in the mac section. Nope. I haven't seen any good mac mp4box gui....
