1) Why is there a warning that there is not a Most Replayed section from YouTube?
If a video is very recent or doesn't have enough views, YouTube doesn't have this data yet. It is best to try once you see the data on the actual YouTube Video. You can look for that when you mouse over the timeline and see something like this:
YouTube doesn't publish the criteria of when this appears, but we believe you need at least a few days and about 50K views minimum. We have seen videos with more views not have it and with less views sometimes have it as well, so that is just an approximation.
2) When are you building automation for this?
It is coming!
3) My Most Replayed clips don't match up exactly with the sections I see in YouTube
We take the peak of the top moments (up to 5 max) and then clip around that time accordingly, basically trying to make sure we start and end with full sentences. We don't actually have the data to match it perfectly to the graphs you see on the YouTube screen, but the peaks you see in YouTube should match up with the clips you are getting.
