How to create a custom Instant Avatar 🤳

Note: Instant Avatars do not support transparency, so if your PNG has a transparent element to it, it will get generated in black. This is not an error.

To prevent the misuse of Instant avatars, we use demographic moderation. Sometimes, this process can result in errors.

Here are the possible reasons for them:

Age moderation failed

We detected a minor in your video. We only allow individuals over 21 to create videos. If this is a mistake, please contact our support team.

🚫 < 21

Safety moderation failed

Your footage should not contain inappropriate content. If you have any questions, please contact our support team.

Celebrity moderation failed

You can't create avatars of celebrities. 🚫 ⭐
