How to give one user access rights to files of another?

Question

linux

Hello. There are two conditional users on ubuntu server 14. The first user dynamically creates folders and puts video files in them, after the first user finishes, the second user must process these videos. But the second user does not have this right. How it is possible so that the second user had full access to all files and folders created by the first? Thanks in advance.

Add these users to the same group -- https://wiki.archlinux.org/index.php/Users_and_groups

# groupadd group
# gpasswd -a user group

user - user login, group - group name.
