In Spark Desktop player, you can use the symbols in the toolbar to:

  • Change the video.
  • Pause the video.
  • Restart the effect.
  • Enable grid view (this symbol only visible for video calling-enabled projects).

Grid view

Grid view is helpful for previewing effects designed to run on a video call with multiple participants. Grid view is only visible when previewing effects configured for a video calling experience.

To simulate this environment:

  1. In the toolbar select the grid symbol.
  2. Use the dropdown to set the number of participants in your calll.
