Video as an exploratory and explanatory visualization mode for scientific data has come of age. Nearly any good scientific talk today includes at least a short video, explaining a concept that is better explained with moving images than with static figures. Some journals even publish nearly exclusively video, in fields where it is so instuctive on its own that less accompanying material is needed. For example, [JoVE](http://jove.com), the Journal of Visualized Experiments, began in 2006 as the world's first peer reviewed scientific video journal.   Including video, like audio, is a challenge in standard journals, even when online, due to the plethora of video (and audio) file formats that potentially need supporting. It is a value-added service of a publisher to advertise which formats are acceptable, and to then migrate those formats in the future so that multimedia content continues to be accessible. Even the modern de-facto _de-facto_  standard paper format, PDF, fully supports audio and video. Both can be included using only LaTeX packages and require no special technology. Videos can present sequential figures, true movies of time-variable phenomena, movies of simulated phenomena in time, or even commentary from authors. Long-term considerations around video, other than the challenge of archiving and format migration, will also involve commenting. As discussed below, it is likely that authors will rely more in the future on the opinions of readers/viewers being recorded as they are included as "comments" attached to the media that form a publication. Commenting tools that involve video are currently maturing, but not robust. In the near future though, both video commenting and commenting on video are likely to be sought-after features.
