seems to work well. how do you source the index for a video?
1) find interesting content and note it on there
2) allow people to search for a spot to go to based on the closed captioning. that sounds pretty neat actually now that i think of it
3) if you wanted to get a little risky, you could watch where people scroll to/pause/get started at from the time stamp query and use that to determine popularity at a certain spot in the video
