How do I replace the audio in an MP4 file without re-encoding?



As an IT admin, it’s often necessary to edit or replace audio in an MP4 file without re-encoding. This can be useful for creating tutorials, instructional videos, or simply for replacing audio that is no longer relevant. Fortunately, this is a relatively straightforward process that can be completed with the right tools.

First, you’ll need an audio editing program such as Audacity. This software allows you to open an audio file, edit it, and save it in the desired format. You can then open the newly edited audio file in your video editor of choice.

Once the audio file is open in the video editor, you’ll need to replace the existing audio with the edited file. To do this, first delete the existing audio track and then add the new audio track. Make sure to adjust the length of the new audio track to match the length of the video.

Once the audio has been added, you’ll need to save the video as a new file. This can be done by selecting “Save as” from the File menu. Make sure to select the same format as the original video, as some formats may not be compatible with certain video editors.

Finally, you’ll need to export the video. This can be done by selecting “Export” from the File menu. Make sure to select the original file format, as some formats may not be compatible with certain video editors.

By following these steps, you can easily replace the audio in an MP4 file without re-encoding. This process is relatively straightforward and should take only a few minutes to complete.

In addition to editing audio in an MP4 file, you may also need to replace the video track. This process is similar to replacing the audio, but involves a few more steps. First, you’ll need to open the new video file in the video editor. Then, delete the existing video track and add the new video track. Make sure to adjust the length of the new video track to match the length of the audio.

Finally, you’ll need to save the video as a new file and export it in the original file format. This process should take a few minutes to complete, and should result in a video that has both the edited audio and video tracks.

By following these steps, you can easily replace the audio and video in an MP4 file without re-encoding. This process is relatively straightforward and should take only a few minutes to complete. With the right tools, you can easily edit audio and video in an MP4 file without the need for re-encoding.
