In-vision commentary

An in-vision commentary is a commentary in which the participants are filmed, and the resulting video is dropped within the video of the episode on which they're commenting. Such commentaries were a major feature of the series 2 boxset, but they were not extensively used thereafter.

However, a form of "video commentary" was later used on the official Doctor Who website, as a part of the Adventure Calendar series. These commentaries differed from the ones on the DVD boxset, in that they were simply recordings of the commentary participants; no footage from the actual episodes was included. Indeed, most of these "in-vision commentaries" were later repurposed as simple audio commentaries either in the podcast series of commentaries used in the RTD era, or on the DVD boxsets. Nevertheless, they were labeled "in vision commentary" on their respective title cards.
