The festival, founded by Initiative Africa, is now in its ninth year and is one of the most information documentary festivals in Africa.
Some of the 60 documentaries this year, selected from all over the world, include 35 Cows and a Kalashnikov, Five Minutes to Freedom, Good Night Sarajevo, I will not be Silenced.
A number of directors will also be attending, including two of Ethiopia's emerging film makers Tirsit Agez and Tamara Dawit. There are also workshops and panel discussions and some of the films will be shown later around the country in Adama, Bahir Dar, Hawassa and Mekele.
The opening is at the National Museum with Framing the Other (about tourism-native dynamics in southern Ethiopia) and will be introduced by Ethiopia's minister for culture and tourism and the head of the bureau for tourism and culture in Addis Ababa.
Screenings are at the Alliance Francaise, the British Council and Hager Fikir Theatre. Tickets are available at the Monarch Hotel and are given out on a first-come-first-served basis.
