This article will take you through all frequently asked questions around videos in Synthesia.
Q: Why is my video still processing?
A: Once a video is generated on Synthesia, it must go through a processing phase that includes all uploaded assets, such as images, audio, and backgrounds. We also perform moderation on all of our content, both automatically and manually.
The overall processing usually takes only a few minutes, but it can take longer depending on the length of your video and the assets used. If your video has been processing for more than a few hours, please contact our Support Team.
Q: Why is my video under manual moderation review?
A: We moderate 100% of our content. Moderation happens through both automated systems and manually. Whilst automatic moderation is instant, manual moderation requires further time for approval. Learn more about Content Moderation here.
If your video is awaiting moderation, it will be reviewed by our Moderation Team as soon as possible. Please do not submit the video multiple times, as this will hinder the process. If your video has been under manual review for longer than 24 hours please contact our Support Team.
Q: Why have I not received my free demo video?
A: If you have not received your demo video, please check your spam folder. If the video is not in your spam folder, it may have been rejected due to going against our content moderation guidelines. We moderate 100% of our content, so if your script does not meet our guidelines, you will not receive a generated video. You can find out more about our Content Moderation Guidelines here.
