I’ve just watched through, and in VLC the audio did feel off by about 100ms. Though I do often find that playing in VLC, you sometimes need to tweak the sync in playback. Did you watch in VLC?
I’m not sure about that final note, but I’ll check it.
Either way, I have some more time today to work on those last couple of bits of audio I’d like to add, but I feel like this is close to release.
