Macromedia Flash MX 2004 Killer Tips

If you have an animation that needs to be synchronized to music or a voice file, you may get frustrated. On your computer, it's in total sync, but on someone else's, things are a bit off. Try putting the entire animation on one Timeline and then putting your sound on a separate layer on the same Timeline. Now select the keyframe that the sound is on, look to the Property inspector, and where it says Sync, change it from Event to Stream. Doing this will force the animation to play in sync with the audio on the same Timeline. Frames in the animation will be dropped if necessary so that the sound and animation frames will always play in tandem.

The only thing you have to worry about is that the sound layer must now have enough frames to play completely. Keep extending the frames of the sound layer if you need to until the entire sound plays back.
