Promotion items on youtube and facebook


I want to promote my item sold on graphicriver
using video on youtube and facebook.

Can I use free music video? (free monts items)

The video I want to include in the description of the item on the graphicriver
Do I have to put a watermark on video and audio?

Mockup has 4 views - one view I would like to make available for free download
Is it consistent with the envato policy?

Hello! You can use audio-preview with watermark from AJ. And put link to item into description.
