Audio synching problems - Please help!

[joebedot]

Hello

I'm making a fifteen minute animated film in Flash 7. It's divided up into 7 scenes of varying length, and each scene has an audio track that takes up the whole length of that scene.

The film is very heavy on lip-synch (in other words, the characters lips move as they speak), but when I export the file as a SWF, the audio begins to lag progressively more and more as the film plays on. I have tried both "Streaming" and "Event" sounds, and Event works better, but for some reason there is still a lag by the time the film is about 10 or 11 minutes in.

It's crucial that I can get the audio to synch EXACTLY to the animation right up until the end. My animation is very minimal, and so shouldn't be too tough for flash to draw each frame

Am I missing something?
Is there an unofficial limit on the length of audio tracks?
Or flash movies?

Please help, I'd be very grateful.
Thanks in advance
Joe

Stream should work better than Event. Stream breaks the audio into frame by frame pieces, so if it matches on the timeline, it should match exactly when you export. That's not happening for you, huh? What format is your audio in (wav, mp3)?

I thought stream would work better than event too, but it doesn't
The audio format I'm using is AIFF, 44.4Khz, 16bit etc, then in the swf export it becomes a 64kb/s MP3 file.
Any ideas??

Check your Publish Settings under the File Menu, you should be able to change the streaming/event sound export options. Whats the frame rate of your movie?
