Replacing Audio in Selected Video Files

You can embed your stereo sound mix in one or more selected video files without re-rendering them. This is not only safer, but also quicker.

Prerequisite

  • Your project contains one or more video events and you have arranged and mixed the audio to a stereo output bus.

  • The video files are compressed using the H.264 codec in the .mp4 or .mov container format.

Procedure

  1. Select one or more video events in your project.
  2. Select File > Export > Video.
  3. In the Export Video dialog, open the Replace Audio in Video tab.
  4. In the File Location section, choose a File Path for the videos that contain the new audio.

    Copies of the original video files are saved at this location.

  5. Optional: In the Add to Video File Name field, enter a string that you want to add to the file names of the original video files.

    The resulting names of the video files are displayed in the Resulting Video Files section of the Export Video dialog.

  6. In the Audio Settings section, open the Channel Selection pop-up menu, and select a stereo output bus.
  7. Click Replace Audio.

Result

The original video files are copied to the specified location, and an audio mixdown of the selected stereo output bus is embedded into the files.

Note

If you trimmed the lengths of the video events in your project, the resulting video files are longer than the video events in the project. As a result, they contain silent portions.

The resulting video files are MP4 files. The embedded audio is compressed using an AAC LC encoder with 192 kbps at a constant bit rate.
