This is a paid service that is absolutely brilliant for anyone wanting to share their video on the net in a format that anyone can see, regardless of what kind if computer they are using or internet connection speed - it's called Helloworld
The picture quality is the best I have seen, and you don't need to scour the internet and download a player in order to see it since it encodes your video in multiple formats so it is viewable on any device - Windows, Mac, Ipod, PDA, mobile phone etc.
You can also use it as an email service and reply to any text email with video.
I have posted some articles about it here on my blog for musicians
I am personally using the service on my own site and also earn a part-time income from it as an affiliate.
This has also given me a lot of great business ideas (since I can run my own virtual TV station with pay per view and post footage on my website or blog).
Well worth having a look at.
