Does Premiere allow audio replacement without affecting video?
Is there any program out there that can easily and quickly swap audio on an MP4 that I spent hours rendering without having to re-render the video? I don’t understand why this isn’t an easy option if audio and video are separate things.
I had an mp3 as the audio track for a music video and now the client sent a “mastered” version of the audio so I need to replace it in place.

-Import the new file to your project
-Highlight the audio to be replaced in the timeline
-Alt/Option drag the new clip onto the highlighted clip in the timeline
-Green + appears
-Drop the clip to replace in place -
Hi Paul,
I believe he means re-muxing new audio without affecting/transcoding the video.
QT Pro could/can do this (though it wasn’t totally straighforward), and there are tons of Windows/Linux Tools available (MP4Muxer is one.)

Yes I ask because I dont want to spend another 5 hours re-rendering just to change the music (it’s the same exact song, just a more cleaner version suited for the video).

Hi Danny,
What platform are you on?
One good idea, in the future, is to export a “Master Version” (something in either Uncompressed, Cineform, ProRes, DNxHD, AVCIntra, Etc.) so you can make changes like this quickly when you need to export multiple highly-compressed copies, or make changes. If you export to a codec like that, you only need to spend the time it takes to encode to MP4, and not re-render the whole thing. Just a thought/unsolicited advice… take it for what it is.
However, if you are on Windows (or have access to Boot Camp/Parallels/Fusion) MP4Muxer will do the trick.
