Transcription: You can play a video clip in a stage by writing a script. We want our clip to play when a button is clicked, so we'll add a satellite button. Open the button script and enter a button click handler. Next, add an mmplay command that plays clip satellite. We want it to play in stage X hat. By adding the weight parameter, we make sure the video finishes playing before Toolbook continues. Finally, update the script and exit. We'll switch to reader level to see our results. Clicking the button plays the video clip in the stage.
