I am a complete nubie at this but I am having so much fun. I submitted about a 45 min long video and it's been 12 hours so far. I hope I didn't break your servers.
The reason I did want a longer video is because Youtube will see time being spent watching my video and increase it for the suggested video search. If I need to cap the time frame just let me know. Can you tell if this video is rendering? I think I submitted it an hour after a second time to see if this was submitted. You can delete the second copy if needed.
If it's been rendering for more than about 4 hours on sho.co it will not render. You will need to cut the scribe down into smaller parts and edit them together after rendering.
