Same problem here. And I have the full license and was uploading over a T1 line at work.
My solution was to upload to sho.co first, then download from there so I could upload separately to youtube.
Kim, I have converted your post into a support ticket and sent a reply. Please check your email for further information.
Alex, you may be trying to upload a .scribe file to YouTube which is not a video file. To publish your scribe to YouTube, click the publish/render icon in the top right corner and then select the YouTube option.
I tried to upload a short video, and that worked. However, I am still not able to upload my project itself. I switched to another internet connection at the university here (which should be allright) and I still get the same notification...
University and some office networks may have upload limits. That could be the reason why a small scribe video uploads and a larger one doesn't.
Other things to try are:
I made the most amazing video for a job application, however, I cannot upload it onto youtube. It says my internetconnection failed, but there is nothing wrong with my connection.. I am in the free trail mode, so I am also not able to save it first and upload it manually on youtube. I also verified my youtube account...
Can anyone help me?
