To allow public have access to video

Hi Saidat, 

Welcome to the Box Community, I'm happy to help!

To make sure that the public will be able to access the file you shared, please make sure that you've set the correct sharing permissions on the shared file. To create a link with public access, you would need to set the link access type to "People with the link".

• People with the link:  Anyone with the link can access the item and no Box account is required. For extra security, you can also set a password or expiration for the link, as well as restrict download and/or preview access for link viewers.

To learn more about Creating shared link in Box, please take a look at this article: https://support.box.com/hc/en-us/articles/360043697094-Creating-Shared-Links

Thanks!
