If they are vetting for attractiveness then they would do at an interview anyway so just bringing it one step forward really - could be a positive thing some might come across better on video than on paper or in an interview. Some jobs paper cant really do justice so I can see why a video would be better at narrowing down appropriate candidates. Just asking for a video will narrow it down, far easier to send off a piece of paper. If it is the sort of role you would enjoy I think probably asking for this format is to your advantage.

Photos I think are worse that really is only appearance but video they are looking for a bit more.
