Since you are new I will give you this advice. never put anything on your site or anywhere on the internet unless it has some watermark on it. Videos, teaser clips, pics, everything needs a watermark.
Your content eventually will get stolen and posted on another site without your permission, and if its not watermarked you just gave your work to someone for free. If its watermarked then you get free promotion and when youre new and small every little bit helps.
