If you look at the bottom of the video (video inside of video), you will see a timeline.
It gives you a preview of what frame is in the video at any given time, by just hovering over the timeline.
This is useful when you want to jump to specific part of the video, but you don't know exactly at what time your desired part is.
I was asking what steemq is..but yeah that feature comes in handy
SteemQ is the upcoming video platform for Steem.
Will be looking forward to it. When will it launch?
When hype stops working for them.
