What you're seeing is not videos, but images belonging to the videos. They are laid out in a row with the image in a column that is 2 wide and the text in a column that is 10 wide. ( total must equal 12 for a full row ).
I believe you're wanting to make the images about 6 wide, so change the col2 to col6 and the col10 to col6 for that row.
