Placeholder image (video only)

  • Before the video is played, a static ‘placeholder’ image from the video will be displayed in the HTML version of the article. Authors should supply their preferred still image (following our standard image guidelines), and the timestamp within the video in seconds for the still image. This will also be used as a placeholder in the PDF version of the article.

Please note that that transcripts (and/or closed captioning) will not be proof-read by Wiley, nor will Wiley be responsible for any of the wording. Authors assume responsibility for the accuracy of supplied files.
