item preview and License premium or not ?

Hi all, I would like to know if I can use a free image or video stock for my preview template on video hive, i read everything on the help center but I’m not sure and if I can do I have to put license in my files ?

It’s important to read the terms and conditions of each image and video stock website carefully to see if their licenses allow for commercial use and if they require attribution. In general, most free stock media websites allow for personal and commercial use, but it’s always a good idea to double-check. If you are using free stock media in a preview template on Video Hive, you should include the proper attribution and/or license information in your files to avoid any potential copyright issues.
Kind Regards,
