Im fairly new to manipulating FLV’s outside of a creating a player or setting up a Component to play it. But I am stumped on how to sync flash animation with an FLV.

I have some alpha-channeled video and I animated it to move around within the flash stage at certain points, and at the end I animate it completely off the screen to make it look like it flew out of frame. Everything was fine until I went to view it on a browser. When I view it on a browser the ending animation where it goes off screen always occurs too late. I even tried reducing the animation times in the fla and still it won’t sync up.

Anyone know what is going on here? I know flvs play at different frame rates than the swf but I have tried both the 29.97 flv and 18 fps fla as well as an 18 fps flv and fla and but still no difference. Do I have to use a cue point to trigger the animation? Should the cue point be action script based or embedded in the flv? Thanks for the advice.
