Your sequence contains audio but the exported MP4 file does not. Which option could have caused this?

• A. Use Selected Tracks checkbox
• B. Include Inactive Audio tracks checkbox (unchecked)
• C. Export Audio Only
• D. Mute All Audio

Answer: (A)

In export, the scope of what gets written to the file is controlled by the track selection. The option to use only selected tracks means the exporter will include only the tracks you have actively selected in the timeline. If you left the audio tracks unselected (or only the video tracks are selected) then the MP4 will come out with video but no audio, even though the sequence contains audio. To fix this, either turn off the Use Selected Tracks option or explicitly select the audio tracks you want to export. Other choices could also change the result—exporting audio only would omit video entirely, and muting all audio would silence the output—but the direct reason audio goes missing in this scenario is the Use Selected Tracks setting not including the audio tracks.
