As long as the content you’re using is licensed properly for promotional usage, AND as long as it complies with Videohive’s requirements (such as not containing visual corporate logos, brands, violence, drug use, etc.), AND as long as you’re not including those assets in the project files, you are typically free to use the visual content.

Regarding audio, we typically ask that authors select a track from and provide a link to the item for proper attribution. Tracks that contain audio watermarks from other marketplaces are not accepted.

ALL media used in preview videos, regardless of images, video, audio, etc. need to be properly attributed with links to their original sources.
