If you have a gmail account then you will already have an account, like Rocket said. You need to upload that video to YouTube (publicly or private - private meaning only people with the link can see the video and public meaning everyone can see) and then give the staff a link
Astrogaming23 Please post the video in hidden content if it worked. Let me know if you have any concerns with this still.
Closing since you have not replied to this thread, feel free to create another help thread if this is still an issue
