bitrate improves quality, but increases file size.
760k (include the k!) gives a nice balance between quality and file size.

PycURL error: ConfigurationError: Curl is configured to use SSL, but we have not been able to determine which SSL backend it is using. Please see PycURL documentation for how to specify the SSL backend manually.

Partly pulled from the comments here: pycurl/pycurl#526

May also be a fix for this error:

ImportError: pycurl: libcurl link-time ssl backend (none/other) is different from compile-time ssl backend (openssl)

If you try to install PycURL and receive this error:
