Frequently Asked Questions
Why is Synthesia rendering stuck?
Video rendering is GPU-heavy. During peak times, jobs queue up. If stuck for 30+ minutes with no progress, cancel and retry.
How long should Synthesia video rendering take?
Typically 2-15 minutes depending on length and complexity. Anything over 30 minutes likely means an issue.
Will I lose credits if Synthesia rendering fails?
Policies vary. Check Synthesia's terms — most services refund credits for failed generations.
