If you are filming a news event, like a protest or violent encounter, please say to the camera at some point, or repeatedly, WHERE and WHEN the recorded action is taking place. Like, "Valiasr Avenue 430pm Tuesday" or "San Francisco City Hall, June 23 at noon". This will greatly aid viewers in understanding, and foreign media outlets in reporting, the veracity, context and chronology of video they receive. Without such information, the lead-in to most videos consists of "we don't know when or where this is but..." and then they try to guess or just say when it was submitted. So, if you are holding a camera, or if you look into the camera and don't know what to say, say WHERE and WHEN this is, and you are doing a journalistic service. It is a good habit for any citizen journalist. The camera takes care of who, what and how. But unless the location and time are obvious (i.e., Azadi Tower in the background with today's newspaper in the foreground), then it is up to the journalist to indicate WHERE and WHEN. This is true with regard to the events in Iran as well as to anyone holding a camera anywhere and seeing news in the viewfinder. My eternal gratitude to anyone brave enough to hold a recording device while the dangers of doing so remain immense. You are the foot-soldiers in a new type of revolution and your bravery is felt worldwide. May peace once again be upon you all.
