You can do what you want but I don't think this particular video is going to give outsiders a good impression of Steem. The video is very far from anything approaching professional quality in every respect. Spreading videos like this far and wide may actually harm Steem's reputation.

The face of Steem to the outside world should preferably be presentable people whose English is flawless. Any videos intended for consumption by large numbers of people should have better production values.
