No... My sounds, and files uploads are doing great. I did have to have my server people make some adjustments to my overall file size amounts, server side. Once that was done I had no issues with those. I have had the video issue continuously. I to am having members who are wanting to upload video, but they get the same result as you or I. (A continuous converting window). I have been at this problem for over 3 weeks now. 

It is a bit upsetting for sure.

I have found today though, that the problem is relevant and persistant here on UNA.io, as well.
