This is tough for me to ask becuae I don't know anything about flash or the terminology. I watched a few flash videos online and at least some of them will allow a thumbnail to appear at the bottom that changes along the "playline" or time indicator (whereever the cursor is, might be called 'rollover'). The thumbnail will show a frame of the video in that particular spot of the video. That feature is really neat and would be very helpful in the video that I am producing. Its almost like a fastforward so the viewer can just skip through and view whatever section they want.
I am using CS5 and edited the video in CS5 Premiere.
