I think the video is very interesting for several reasons. The first is the deck crew. They look like they went shopping at U.S. Navy Carrier Incorporated. Float coats and cranials, A couple of weird colors in there, but a lot of the colors are exactly the same including jobs. I noticed they were using yellow for flight directors and launch directors, safety in white, arresting and launch gear in green.
It wasn't in this video, but in a Chinese media release they showed the use of deck mounted "chock plates" that rotate up in front of the tires allowing the plane to throttle up without using the brakes. This is really interest compared to other "deck run" type carriers. One thing that is apparent from this video is that those plates are built for the SU-27 variant aircraft only. There doesn't appear to be any other sets of chock plates in the deck.
For the super nerds here is a link to the Chinese (propaganda) news piece. It shows some more footage of a FOD walk, some deck ops and setting up for the launch.
