I'm working on a intranet project full of about 14 sections with a FLV video synchronised to an animation.

Initially when we started animating - we embedded the FLV file on the timeline with a MP3 track so we could organise the correct times for animations to trigger - Due to multiple people working on the project a lot of the animations are nested and triggered by actionscript calls. When i convert the video to a external FLV (with a 5 sec buffer) the performance and sync of the video doesn't work. It will drift out of sync.

For example, if you play it on a Mac (G5, with either flash 7 or flash 8 plugin) the video with play at the correct speed (25fps) but the animation will play at about 12-16fps. On a PC depending (2.4 Ghz) the animation will keep in sync but on a 1.8Ghz it will drift behind (although not as much as the mac)

An example can be seen at http://www.subtle.co.nz/telecom/ i have posted both the version with an embedded SWF and the external FLV version.

We are still optimising all the file sizes - Macromedia says that you shouldn't really embed long video on the timeline but flash will only really drop frames when the flv is embedded.

Is there any way of alleviating this?

Cheers
