If you see the "something went wrong" message, it means that your video has unfortunately encountered an error during the rendering process and has been dropped from the queue.
Our team is notified whenever a rendering video encounters an error, so chances are that we're already investigating the problem as you're reading this message. Once we've fixed the problem, we'll put the video back into the rendering queue, and you'll receive your video as usual!
You can expect to see the video back in your dashboard, fully rendered and available for download, by 11am PST the day after you see this error (or the same day, if the error occurs before 10am PST).
If you're on a tight schedule, you can make a copy of the video and try replacing some of the media assets in it before attempting to render again. A lot of render issues are due to errors with the selected media, so this is a good strategy if you don't mind a little trial and error.
We're constantly improving the system to reduce the likelihood of rendering problems, but in the meantime you can also try creating another video.
