Hi Paul, you can upload videos directly through DTube ( https://dlive.io/ ) which is the YouTube equivalent on the steem blockchain.
You need the free @steem-plus browser add-on to include the signature & image in your comments.
It is available on Chrome (and Firefox as well I think).
It is probably worth getting an account on Discord as well as that is where most day-to-day communication is done for Steem. You can find me there @Pennsif#9921.
If you need any help with anything just let me know.
Host of The Alternative Lifestyle Show on MSP Waves Radio.
