Youtube.com (some features not available), Twitch.com (Really good but it depends is you upload HD or not and maybe doesn't have unlimited storage idk) these are the ones I know Hope it helped.

Not exactly what I was searching for but, best answer anyway.

Hello!

I am looking for a video sharing service similar to that of sockshare.

I need this service to perform certain tasks and I require the following features:

Streaming Capability

Free Hosting

HD Support

Embed support

Unlimited Storage

Minimal to no copyright take downs?

Also, unlimited file sizes would be great!
