Clip is a commercial for the Boy Scouts of America. 

Shows a group of boys in uniform hiking, making a bird house, hopping from tire to tire, eating hot dogs, climbing a hill, jumping from rock to rock over a river or stream, sleeping in tents, camping beneath stars, making beds, and climbing over a wood fence. 

In the final shot, a boy tells his dad that he wants to be a cub scout and asks whether this is OK.
