Lesson 20. Synchronizing with Digital Vi... > Playing a Digital Video Cast Member

Playing a Digital Video Cast Member

Like a sound file, a digital video cast member will play only as long as the playback head is in the frame that contains it. For example, if the digital video sprite is in just one frame of the score and the playback head is moving at 15 frames per second, you will see only 1/15 of a second of the digital video when the playback head passes through that frame. To play more of the digital video, you can use three techniques:

  • You can extend the video sprite's duration in the score. The video plays as long as the playback head is moving through the frames that contain the digital video sprite. This technique alone is usually impractical, because it is difficult to match the length of the digital video exactly to the length of the digital video sprite in the score, especially when you do not know the capabilities of the user's system.

  • You can use Lingo to keep the playback head looping in a frame that contains the digital video sprite. The video continues to play while the playback head loops. In this case, the duration of the sprite in the score is not significant. The sprite can span one frame or many frames, so long as the last (or only) frame keeps the playback looping (in most cases, with an exitFrame handler containing a go to the frame command).

  • Use cue points to synchronize the video playback with other elements or continue playing the video to its end.
