GUIDELINES
FOR USAGE

Help

Best practice is to select from a picklist of values.

If the aspect ratio of a media item being described is outside of an expected video/film aspect ratio, then enter the data as an "other" option or customized data entry, depending on the information or digital asset management system in use.

For a comprehensive review of digital video and the evolution of our past, current, and upcoming digital video horizons, please reference an intriguing web site called gruntmedia whose mission "is to use the podcasting platform as a means for publishing short videos that tell stories about the basics of things." One of their service channels is named videogrunt where a growing directory of podcast videos clearly illustrates the concept of aspect ratios for digital video and HDTV.
