As to soap operas, ITC (2000) suggests inserting a kind of reminder at
the beginning of the programme, since there is less need to repeat the cast
that is actually always the same. In case a new character is introduced, it
might be useful to insert a short description of the character, to help visually
impaired viewers familiarizing not only with his/her voice but also with
his/her physical appearance and behaviour.
In nature documentaries, although there is already a commentary, it can
be useful to insert audio description in the long pauses where only sound is
heard. In addition, since part of the viewing impaired population is totally
blind and has no mental image of the appearance of nature elements, whether
it is vegetation or animals, audio description might intervene to explain how
things look like, which is not usually provided by own commentary within a
documentary. In current affairs documentaries, which traditionally need little
or no description at all because they are mostly spoken, sometimes it is
useful to voice the on screen subtitles that are inaccessible to visually
impaired people.
Sport events are also quite difficult to audiodescribe. Indeed, a
distinction should be made between live sports and pre-recorded sport
performances. For the latter, although it is possible to insert some audio
description strings, putting this principle into practice is somehow impossible
because of the short time audio description should be delivered. This
