Hello all,

I got a little problem ... I've got a bunch of video files (*.mp4) on my Mac and need to filter out some "noise" (Basically those are captured from old VHS tapes). I managed to extract the Audia Track and (using Audacity) and to save to the properly filtered Audio file to a *.aiff file in teh same folder as the *.mp4 video files.

So this is where it gets difficult: How can I replace the original audio track with the new one?

I've got MPEG Streamclip installed, but cant for the live of me find out how to use it to do this "MUXing". Any advise would be much appriciated

(BTW: If there are other better tools, pls let me know as well)

Best Regards,

Yonz
