I am new to animation and I use Adobe Flash Professional CC and Actionscript 3
So when I'm editing the animation, I'll add the audio (mp3 file) and sync everything together. But when I get to exporting the video, the animation moves a lot faster and doesn't sync with the audio anymore. The red play line lags whenever I play the video on Flash, and each time I play the video in Flash, it lags a little bit differently. The red play line doesn't follow the audio's volume waves on Flash but with the animation. I have 2867 frames playing at 24 fps, and the animation lasts for about 3 mins when I play it on Flash, but 2 mins when I export it and play it on Windows media player. The audio seems to play at the right time, so it ends a lot earlier than the animation when I play it on Flash.
I'm not sure if this problem is to do with my computer or Flash, but every time I animate something with audio, i have to export it multiple times, then go back to Flash to add or remove frames so that the animation syncs with the audio, which makes the animating process a lot longer.
I also have another problem, which I'm not sure is related, but whenever I pause the animation in Flash, and press play again, the audio stops working.
Thanks, I'd really appreciate any help.
Synching audio to video in Flash is not as simple as it might seem. There are a number of variables that can lead to problems. Here is a pretty thorough explanation of the process: Adding Sound to Flash Movie Timeline and Choosing Flash Sync Sound Options - Flash Event Sound vs Flash Stream Sound Tut… This should give you a basis to start with.
