You could also try to upload it to dLive. And they don't take 25% from your author rewards like dTube.
There's also another decentralised video hosting platform called view.ly , but their sign up process is quite convoluted, however their quality is hi-resolution.
dTube overcompresses videos depending on how much SP you have.
Not dissing dTube, but it still has many flaws at this stage. I'm sure they'll iron it out soon.
