Video

Overview

The Coherent Prysm Player can load a video through the <video> HTML tag and the Coherent Prysm Exporter makes it possible to create it by simply clicking a few buttons in the panel.

Videos have the following notable restrictions.

  • Videos must be in the webm format.
  • Video tracks must be VP8 or VP9 encoded.
  • Audio tracks must be Vorbis encoded.

More about video support in the Prysm Player can be found here.

Creating video HTML elements requires the following two steps.

  1. A video source file is added to the document.
  2. The source file is used to turn the bitmaps of a movie clip into video elements.

  1. Select the movie clip on the stage.
  2. Open the "Properties" tab.
