View Full Version : Making a music video -- audio-video sync?

04-07-2007, 04:34 AM
Apparently, the sound file must be set to stream to assure synchronization.

I also read this somewhere:

Note that it's critical to add a preloader to allow the music file to properly stream down to the player before playback begins. With the sound file set to Stream, the animation and song may be out of step with each other if this step is not taken.

What does this mean? If the song it's set to stream it just isnt loaded in the preloader -- how do I make it load?

One more question, what is the optimal framerate for a music video? 30?

I am unfamiliar with this area but i do know that the question is asked a lot.
Do a forum search for "sync audio to flash".
It might throw up some answer.

Sound must be a timeline sound, it's Sync set to "stream". Not the same as loading a dynamically streaming sound.
You could make the sound a timeline 'stream' sound set in a external.swf, which could be loaded in to your main video movie...
Then your above line makes sense, since you'd have to be sure the external sound .swf is fully loaded, before starting up the main video movie, to ensure sync was maintained.

I think my old Flash AV guy used to use cue points to tell the audio when to start. That may be a good starting point, if of course that is even your problem.
