Alice Averlong🏳️⚧️oh god. I thought every social media was breaking my audio when uploaded, but no, they're transcoding my mp4 into a perfectly sync'd mp4.
which firefox/their video player then plays out of sync.
I feel like less shit for making a video that played wrong, I thought I fucked up the sync.
