Audio issues when exporting to YouTube
Since an iMovie update in October 2020, I have been noticing audio 'pops' in videos exported to directly to YouTube. These pops do not appear in iMovie while I'm editing, meaning that they only appear after the file is exported and processed on YouTube. I have tried exporting the video multiple times, however these glitches still appear. Interestingly, they appear in the same place for multiple exports of the same video. In the YouTube video linked, you can hear them at 1:06, 1:16, 1:35, 2:54, 3:48, and 4:18. https://youtu.be/ekZhkCMFYv8
I've tried uninstalling and re-installing iMovie, however I am still seeing these problems. Any assistance would be appreciated.
iMovie version 10.2.1
