I use CS4 on Windows 7. I have a lot of RAM and a big CPU. And yet, I am having trouble getting the exported video from my animated cartoon FLA to match the good motion/synch on the SWF. The FLA is sized 1920x1080. I have been exporting it down to 640x480 with various export settings for video and sound. The product slows down the motion at early moments like a scene shift tween, while the sound moves along as scheduled. Simply put, I want my MOV file's animation to perfectly match that of the SWF.
if you sound is attached to the timeline, change its sync property from event to stream.
I tried that with the first sound file. When I did, all the other sound files began playing prematurely on the SWF. Should change all of them to stream, then playback?
all sounds that you want to sync with the timeline should be assigned the stream insteda of event property.
