About your avatar - no idea how long it's been since you did this recording, but there is two things that affect your avatar's ability to follow your movement's mouth opening. 1st was as you guessed - light levels, i ususally have my living room light on even during the day (Although avoid point the camera at the light itself :P). 2nd is the input resolution ofthe camera -I have my camera set to 4k input and 720p output (So the camera send 4k data to tthe v-avatar program and the program send 720p data to my OBS software). but anyway, WHO coulda guessed the Ghostie would get revived due to the power of friendship XD
