I believe that there were giants, or what they called giants back then.
Angus Mòr MacAskill, frequently referred to as Giant MacAskill (1825 – August 8, 1863), was known as the world's largest "true" giant (normal proportions, no growth abnormalities). The 1981 Guinness Book of World Records lists Angus as the tallest natural giant who ever lived, the strongest man who ever lived, and the man having the largest chest measurements of any non-obese man (80 inches, or 2,000 mm).

As a child he was also said to be of normal stature, but in entering his adolescence he began to grow rapidly and by his 20th year had attained 7 ft 4 in (2.24 m), eventually reaching 7 ft 9 in (2.36 m) within another year or two. His early adult weight was 425 pounds (193 kg), but usually was over 500 pounds (230 kg). His shoulders were 44 inches (110 cm) wide, and the palm of his hand 8 inches (20 cm) wide and 12 inches (30 cm) long; by 1863 he was wearing boots 17.5 inches (44 cm) long. He had deep-set blue eyes, a musical, if somewhat hollow voice and a mild and pleasant manner. Despite his size he was well proportioned.

I have no idea if giants existed, but please do keep in mind that the video in the OP contains many images of well known/documented hoaxes ... that in itself all but kills the cred of the video
