Am I allowed to use anything I download from this site on my YouTube videos?

Hello friends.

I just signed up tonight. I read through the terms of use, but a lot of that went over my head. Basically I have a YouTube channel, can I use any of the stock footage I download from here on my videos risk free? Or are there specific tags or something I have to look for with the videos when searching the site? Obviously I can’t market or sell these videos I download as my own, but there’s no issue with having this stock footage in my videos and then later down the line monetising my videos?

Can I use one piece of stock footage across multiple YouTube videos? Or do I have to download the footage again for every specific YouTube video I use?

Also, I’m guessing I have to credit envato in my description for using the stock footage?
