Your rank is still newbie so it will be hard for you to find those reliable bounties that can give you a good stake. The lower rank you'll join to bounties, lower stakes you'll receive so I don't recommend it for you.

You can't only use your video creation skill to bounties but you can also offer it on the Services section to increase your way of earning.

There are paid articles too which will be beneficial to you so I'll say that stick to these two.

If you still have enough time of joining social media campaigns and you've got plenty of followers to twitter / facebook then join.
