Music Video Planning - Filming

Today, I carried out the filming for my music video. I found it difficult as the casting i had enrolled didn't know each other so I feel that there was an awkward atmosphere between them. I also feel that when lip syncing my male could not take things serious, this put me in a very stressful situation as I had to film the same scene a number of times more than I usually would. The whole filming process became very stressful and I now have the worry that the filming isn't very good.
