Much work in scientific visualization has addressed the question of appropriate graphic representations for formatted data. Video contains both pictures and a sound track. DICs can be derived from a video BIC by using one or both of these elements. The sound track can be converted to text. Frames can be selected from the video.
Video abstracts can combine elements of both.
Several issues arise in these conversions. A conversion that preserves content may not be completely reversible. For example, translating a novel into another language preserves the content. But an attempt to translate it back into the original language would be unlikely to restore the original. But changing a pie chart into a bar graph can easily be reversed.
