It was a touch of artistic genius to have the ship crew talking, and making facial gestures, all adding to the immersion of the story being told, so well done FD for this creation.
We know why you did this, and that it is not part of the regular game. However, I wonder if you should add a caveat in the small print at the end of the video to point out that lip-sync is not available in the main game (you said so in the live feed) because newcomers to ED will not see the video with this context and may falsely believe the game already has this feature.
It would be nice to think you are working towards talking avatars
