What is the new way to upload videos on my site (since the last Wordpress update)

Hello,
I already uploaded videos from my computer to my site in the past. But today I tried and curiously this time its didn't work. There a limit of 64Mb, if I remember well...
So what is the new way to upload my videos on my site, from my computer? (not from youtube). I saw an wpmuvde article on that subject in the past, but I can't find it anymore... What can I do?
Thank you again for your help guys.
