From the Adobe Creative Cloud blog by Zeke Koch:
We've just added over 100,000 native 4K video assets to our ever-growing content collection on Adobe Stock. 4K is increasingly becoming the new standard for video production - it provides significantly more image detail than HD and gives you editing options you wouldn't have at lower resolutions.
These new videos are native, meaning they were shot in 4K or rendered in 4K, which offers more precise edges for creating and editing.
Adobe Stock already includes over one million video assets and over 45 million images and graphics. Read more about our announcement on our Creative Cloud blog and watch Adobe Stock 4K videos below
Adobe Stock video content is available for licensing on stock.adobe.com and can also be searched and purchased directly from the Creative Cloud Libraries panel in Premiere Pro CC and After Effects CC and from there dragged directly into an open project. Whether you need video clips for corporate or commercial use in videos, commercials, television shows or websites, Adobe Stock will have the video content you need.
These new 4K assets are available today for $199.99. While standard license terms apply, there is no limitation to the number of impressions. (HD versions of the 4K clips are available for $79.99).
