I have sony vegas (movie studios version) i usually dont have issues with render time unless i have a TON of things going on in the video like HD footage from other sources and different editing tools and what not but sometimes that can be your computer that may be keeping it from uploading quick. There are a few settings they have that can speed up the render but may effect the quality. I had issues back when i was using a laptop to render and edit but once i upgraded to an actual desktop my issues stopped.
