Problem whit my loading screen

In the script I use for my loading screen I am suposed to use a .gif url.

But I want to use my folder video but I do not know how I do it. I work on it and I am not able to find how to do it. I know it’s simple but if you are able to help me, I will be very happy.

Search “set video as background html” On google, alot of guides on how to do it :smiley:
