Synthesia Video Stuck Generating
Quick answer
Videos pass six stages (Moderating, Queued, Preparing, Rendering, Assembling, Finalizing). A long wait is usually manual moderation review; do not regenerate, which lengthens the wait.
Most likely fix: Wait and do not regenerate
How to fix it
Try these in order — the most common fix is first.
1. Wait and do not regenerate
- Repeated generation hinders the process and increases wait times
- Leave the video as it is
