Sometimes, videos get stuck in transcoding.
We have a script that runs every 24 hours at/around 12:00am EST to remove videos that are stuck in transcoding. Please make sure you have given this script sufficient time to run in the event that you have a video(s) that may be stuck. If 48 hours has passed, and your video remains stuck, you may write into our Technical Support Team - although, this is a rarity as our script removes these files 99% of the time.
Here are recommendations to try to prevent videos transcoding issues:
Make sure your video files are compressed per our guidelines.
Make sure your internet connection is strong.
