In this, I don't blame TEPCO for not having posted a video of the entire work (9 to 10 hours) on November 18, 2013.
The preparation for submerging the cask started in the morning, with the cask submerged completely at 12:30PM. The removal of unused (new) fuel assemblies into the cask started at 3:18PM, and by 6:45PM 4 unused fuel assemblies were transferred into the cask.
The names of the companies and the names of the workers are blurred in the video. They could be TEPCO workers, but most likely from one of the primary contractors.
From TEPCO's photos and videos library (11/19/2013):
Compared to the still photos (see below), the water in the pool looks slightly murky. After the day's work ended at 7PM on November 18, another set of workers were scheduled to be there all night, clearing small debris and particles using a vacuum cleaner in the water.

Today (November 19, 2013), the workers have removed 8 unused fuel assemblies into the cask as of 1:30PM, according to Nuclear Regulation Agency (secretariat of Nuclear Regulation Authority). The Agency thinks the workers will be able to remove additional 10 fuel assemblies to fill the cask.
There are six group of workers who take turns in removing the fuel assemblies so that each group of workers spends less than 2 hours on the operating floor.
