Here is the end snip of the output from the troublesome node: After doing some digging I discovered when Saber is not present in the comp the issue goes away. It will start and render the quicktime all the way up to 100% but never report that the task is done.
One of our nodes refuses to finish a render. Because of the hundreds of files we generate I use Deadline to slave them out. Our graphics package utilizes the Video Copilot effect “Saber”.
