Hi everyone I was searching online for my problem and ran across your forum, I hope you don't mind me stopping by to ask a question.

Basically I have 2 files, an mp4 video file with no audio and an aac audio file that corresponds to the video. What I want is to make so that they are just one mp4 file. This way it will be compatible with any program I want to play it in. I can sorta do it now, but all the programs I try to do it in want to compress/convert my video file again. Is there anyway to just add the audio "back" to the video?

Thanks a million,
Jack
