The quiz and exercise questions are designed to test your knowledge of the material covered in this hour.


1:If your video has a frame rate of 29.97 fps (a likely rate if it was made for television), the videos in your Flash movie will be slightly out of sync with the audio, unless you do what:
  1. Use video from Europe on the PAL system (which is exactly 25 fps).

  2. Click the Synchronize option when importing.

  3. Use 30 fps in your Flash movie because this is “close enough for television.”

A1: B. It's that easy. In fact, it's probably not terribly noticeable. Also, PAL video is 25 fps, but that has nothing to do with the question.
2:How do you change the compression on a video that you've already imported?
  1. You can't. But, instead, you could re-import and recompress at that time.

  2. Simply access the video item (in the Library), select its properties option, and then press recompress.

  3. You simply need to modify the Publish Settings, Video tab.

A2: A. Answer B is actually close because you can re-import from the item's properties—but that just invokes the compression dialog box again (and requires that the original video file still be in its original location).
3:Sorenson Spark is…
  1. An old technology that could cause sparks to shoot from your monitor.

  2. The compression technology included free with Flash MX and the decompression technology used in the Flash player.

  3. An option (that costs extra) to compress your videos with supercompression.

A3: B. As a “codec,” there are both compression and decompression components. There is a version called Spark Pro (that costs extra), but realize that users with the Flash player will still be able to view Flash videos that use this version.
