Free Stock photos and videos Websites and blogs

Hi, I am working in a firm as an art director to create some creatives and social videos.

so,we need some resources for that like stock music, photographs and videos.

I know some famous sites are selling these elements are paid or subscription basis. like Envato.com and stutterstock.com etc.

But sometimes we need these things for free I did shortlist some free stock photos and videos.

For music use, youtube music resource is best and there are lot more free music sites. you can download for your videos from there.
