"Unable to find a suitable output formula" error message

m8r-295go3
Hello,

I would like to download the video embedded onto this webpage: http://www.iamagraduate.com/lse/ceremony01.html

So far, I have tried using this command:

ffmpeg -i "http://content-ausc2.uplynk.com/96f2bc1283574d0eabf5cbacde547f55.m3u8?cid=96f2bc1283574d0eabf5cbacde547f55&oid=8ab72384e3aa4ceb8e59b5d2af64e262&exp=1451557845&rn=1721083425&tc=1&ct=a&sig=55b1597c4d9f330042fe24a260801b87bc982cc58076d21c0d4ccbb386b49646" -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 Homebrew...

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

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

Thank you!!

Normally, you are required to post the full output on this list to get help.
In this case, the snippet you posted was enough to know the problem, but in
the future make sure to do it.

You must use normal ASCII double-quotes, like that: "...", instead of
asymmetric double quotes like that: “...”. You may also use single
quotes/apostrophes (the ASCII symmetrical one, again) or no quotes at all if
your filename does not contain any special character. Peruse the
documentation for your shell to know the difference it makes.
