I would like to download the video embedded onto this webpage:

So far, I have tried using this command: 

ffmpeg -i
-c copy “grad.mp4”

(Please note that the "exp="... part expires every 30 seconds, so every time
you reload the page it will be different)

However, this is the output I get when I use Terminal on Mac with

[NULL @ 0x7fd01b8c7600] Unable to find a suitable output format for
“grad.mp4”: Invalid argument

This is my first time trying to copy a video... does anyone know what I am
doing wrong?

Thank you!!
