Although I am not keen on recording a video of myself, I am willing to give VI a try!
I tried to chose pictures taken on different occasions and where I smile/don't smile in order to have a better general view.
Any wild guesses?
EDIT on 10/11/2019:
I have now recorded a 17 minutes video for additional evidence.
If you are interested in this video, just let me know and I will send you a link in PM.
