AUDIO – VISUAL used to be slides and sound, combined with commentary sometimes. Short series, anything from 1 to about 10 minutes. Digtial has changed that, we now can incorporate Video. For normal competition purposes, the time limit is still the same. Some events stipulate short times, themed or open. Very few AV festivals allow about 20 minutes. The amateur and professional film events overseas want longer videos, especially for ducumentaries and travel series, from 15 to 45 minutes or more.
