i love videos. Videos can show the real you versus a picture that took hours to get the right lighting, etc.
Usually, when someone seriously asks me "Do you think I pass" and they want a very thorough answer, I ask to see a video of them. Also, when they talk I listen to their voice since they asked me if they pass, the voice, in my opinion, is the biggest attribute. And it's more than just the voice. I see how they reflect, their gestures, and a video shows more of a person than a picture carefully taken.
A video, other than being there in real life, is the strongest media to see any changes on a person. Pictures not so much. And this is one of the biggest reasons why you don't see me in the "Do I pass" thread as much. Cuz, it takes more than just a picture for me to know.
