I dont understand Pond5 License

If im buying a video on pond5 (individual), am i free to use it on youtube forever? can i use it in one or all my videos? do i need to attribute pond5 even tho i bought a license and if so do i need to add a link to the site? to the creator?

royalty free is you can buy and use it in any project you create forever. You just can't resell the original footage as you bought it or give it to someone else to use, meaning, its yours to use but you don't own the copywrite to sell or give away. That belongs to the original creator.

You don't have to attribute pond5 or the artist that created it but if you have a list of credits, it would be nice to list the artist that created it.
To many times I see the site its bought from and not the creator.
