...if I want to sync slides to an flv, and I have all the timings (and the sucker is longer than the timeline frame limit permits), what's the best method. Cue points work, if you watch linearly, but if you scrub back, the slides don't re-order.
Do I have to "listen" for the playhead position and reference that position to an array of time/slide intervals?
When it is not necessary to do something, it becomes necessary NOT to do it.
I use a platform called Arctic fox, it allows you to upload large videos and sync a slide presentation with it easily. It's easily the cheapest easiest and most straight forward solution out there. You do it all online and upload the content, input your slide times and end up with your own url to send out or embedd. Its also the only platform i know about that uses HTML5 so you can watch it on ipads and iphones
