Owww, I thought 3Speak is not that complex? I think I uploaded once a video through them. The good thing with 3Speak is that you can choose the first tag yourself, which basically means you can select the community the video goes into. Ok, 3Speak is probably a bit more complex then uploading to YouTube and sharing that one to HIVE. The reason I advise you to check 3Speak is that you may get attention by the 3Speak team as well; They can give good upvotes when they like content.
