Why doesn't my video have a thumbnail?

You might want to share a video on Twitter, Facebook, or even Instagram (if you are using our companion mobile app) but you noticed that a preview isn't generated.

Does this mean something happened? Will the post be uploaded correctly? All of those are valid concerns!

But, don't worry! Your video will be uploaded and shared correctly. The black thumbnail will change once you've added the post to the category. Just give it a minute or two to load.
