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.</p> <p>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.</p> <p>Please note that multimedia files must not include any music.</p> <p>To make multimedia files accessible to as many readers as possible, the caption accompanying the file must include a description of the key points demonstrated by the video/audio. If the time duration of a video is long enough, we encourage authors to add a voiceover describing the key points illustrated. If the video already has audio, try to record your description in spaces where the original audio is not crucial to the information in the file.</p> <h3>Technical specifications</h3> <p>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.</p> <p>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.</p> <p>Recommended settings:</p> <ul> <li>Frame rate: 15 frames s<sup>-1</sup></li> <li>Frame size: 480 x 360 pixels</li> <li>Data rate: 150 kB s<sup>-1</sup></li> </ul> <h3>Interactive figures</h3> <p>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.</p> <p>To make interactive figures accessible to as many readers as possible, the caption accompanying the figure must include a description of the key points demonstrated by the interactivity.</p> <p>Example images:</p> <p><a href="http://iopscience.iop.org/article/10.3847/0004-637X/818/2/115">http://iopscience.iop.org/article/10.3847/0004-637X/818/2/115</a> figures 2 and 3</p> <p><a href="http://iopscience.iop.org/article/10.3847/0004-637X/819/2/113">http://iopscience.iop.org/article/10.3847/0004-637X/819/2/113</a> figures 1 and 5</p> <p>Interactive models should use the X3D standard. This is an open-source, XML-based format curated by the International Organisation for Standardization (ISO). By using the X3DOM javascript/CSS combination, X3D models can be incorporated directly into HTML without the need for browser plug-ins. This can be downloaded at <a href="https://www.x3dom.org">https://www.x3dom.org</a>.</p> <p>We strongly recommend the use of X3D/X3DOM but stand-alone interactive figures produced using alternative packages (such as Plotly <a href="https://plot.ly/">https://plot.ly/</a> or Bokeh <a href="http://bokeh.pydata.org/">http://bokeh.pydata.org/</a>) are also accepted.</p> <p>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.</p> </div> </div> </div> <div
