Using proxies:
$ proxyload
Format the first line of ssl_proxies.txt to remove everything but the ip address at the end (or just delete the first line)
$ protofix https ssl_proxies.txt | sort -R | sort -R >> sort_ssl.txt
$ endtube --ua-rand --proxylist sort_ssl.txt --list list.txt

Add proxycheck to the workflow to get working proxies only. 
$ proxycheck ssl_proxies.txt
$ protofix ssl_proxies_yt.txt | sort -R | sort -R >> sort_ssl_chk.txt

If you have a better workflow feel free to share.
