IOPscience allows inline presentation of multimedia files within journal articles, with videos, animations or sound files that are supplied by authors as part of the main article treated as figures (please note that multimedia files must not include any music). Multimedia figures are represented in the PDF by a static image with appropriate caption. In the HTML the same image and caption are displayed, readers can click/tap the image to play the multimedia file inline.
If a figure has more than one multimedia file, there must be a separate image for each file (e.g. parts a and b for a figure with two videos). This is necessary so that the files both display in the HTML.
We strongly recommend video files be delivered in the MPEG-4 container, encoded with the H264 codec. Other formats may be provided, but using MPEG-4 will provide the most faithful rendering of your video in the HTML journal article.
Video files should be a maximum of 10 MB file size each. Exceptions can be made in cases where larger files are essential for the science being presented.

Authors may prepare interactive models to enhance the communication of their research. These models are treated as figures in the article. Each model is represented in the PDF by a static image with an appropriate caption. The HTML in IOPscience displays the figure and caption with a ‘Start interaction’ button which loads the interactive model within the flow of the article.

We strongly recommend the use of X3D/X3DOM but stand-alone interactive figures produced using alternative packages (such as Plotly https://plot.ly/ or Bokeh http://bokeh.pydata.org/) are also accepted.
Authors interested in using this functionality need to create and supply the interactive model and an HTML file that presents the model, along with all .JS and .CSS files used.
