Considerations when switching from video and audio-only
If you have a composition where you have created video content, there are a few things to remember before switching your composition to audio-only.- If you do not need to edit the content further, you can always export your video composition as an audio file.
- Video layers will still be visible in your timeline when switching to audio-only.
- You cannot export a video file while working in an audio-only composition; you will need to switch the composition back to a video to export a video file.
