FAQ

Your Questions Answered

Everything you need to know in one place.

What types of files does Facemint support?: Facemint supports image formats (JPG, PNG, WebP), video formats (MP4, MOV, M4V), and animated formats (GIF, WebP). Maximum file size is 2GB, and video length is unrestricted.
What’s the maximum video length supported for face swapping?: We don’t limit the duration of your video. As long as the file size is under 2GB, you’re good to go.
Can I choose which faces to swap in a video or image?: Yes. Our API automatically detects all faces and allows you to swap one, several, or all. You can assign the same identity to all, or different identities to each face.
How is pricing calculated?: You only pay for what you use — pricing is based on the actual resources consumed per task.
Can I trim videos before swapping?: Yes. Our API allows you to trim videos before processing, so users can accurately select the desired segment before the face swap begins.
Is face enhancement included or optional?: Face enhancement is optional. When enabled, it improves clarity and realism — especially useful for close-ups or HD content. You can toggle it on or off per request.
Can I add or customize watermarks on the output?: Absolutely. You can enable/disable watermarking and fully customize the text, position, size, and opacity — ideal for branding, free previews, or demo protection.
How fast is the processing time?: Most image tasks are completed within seconds. Videos vary depending on file size and resolution, but generally complete in minutes.
Are there any usage limits?: There are no restrictions on how many tasks you can run. As long as your usage stays within the API rate limits, you’re free to process as many tasks as needed.
Do you store uploaded files or generated results?: No. We do not store any user content. All files — including inputs and outputs — are permanently deleted immediately after the task is completed.
