Best I can tell, audio/music can only be added in the beginning - in preferences. Correct?
The only way to add separately recorded audio is to record the time lapse as photo, not video. Then, export the photos to a 3rd party editing app (apple, adobe, etc.). Is that correct?
Also, if audio is added in preferences, it is embedded in the file and cannot be removed later. Correct?
Thank you
