Wait until the consulate make appointment to interview you (if they do), and provide your video at that point of time.
I am doing almost the same thing as you. I have recorded her verbal resignation when she said she resign. Later on, I will still chase her for a written resignation , but I am prepared that she doesnt write it. If it happens like this, I will also write her a letter to tell the background first and to state that the one month notice of termination I give is a response to her verbal demand for breaking contract.
