I just uploaded my first video to 3Speak video site. It was definitively lesson in patience, but it finally worked. Video got stuck Queued for encoding for few hours (actually slightly over 2). This is improvement from yesterday because I was not even able to finish upload.
I understand common video site workflow: user uploads whole video source file and site will re-encode it for lower bitrates. This is standard nowadays and user expects video site working that way.
