ClipsReel - My video is stuck in "Rendering Pending" status

Rendering time may depend on several factors like the number of slides that you have created, the resolution of the images that you are using, the internet speed, browser issues and other factors like unusual traffic and ongoing server updates. If you encounter such an unusually long rendering process (e.g. "Rendering Pending" status), refreshing the browser/page would be helpful in most cases.  You may also clear your cache/cookies then recreate campaign.
