Like a lot of posted videos, this one is truncated. Video editing software must cut things shorter than one expects. The result is really annoying. Why don’t editors view before they post? (I am not complaining about the FR poster. The problem is with the video clip from the original site.)
Have you not seen the actual video?
I don't use TikTok but I believe the app limits the time of videos. If the big event happens at the end, you're out of luck because the recording will stop when time is up.
Best to use your cellphone camera or a digital camera.
