Frequently asked questions
Everything about making mermaid videos, your privacy, and billing.
Creating videos
What is an AI Mermaid Video Generator?
An AI Mermaid Video Generator creates short, animated mermaid videos from a text description or a photo. With Monnvia you describe a scene (or upload a picture), pick a style such as Anime, Watercolor or Cinematic Real, and our video model renders a short clip with realistic water, light and tail motion.
How do I turn a photo into a mermaid video?
Open the generator, switch to Photo to Video, upload a clear, well-lit photo, confirm that you own it and have consent from everyone in it, then add an optional motion prompt like 'she swims up toward the moon'. Press Generate and your video is usually ready in one to three minutes.
Is the AI mermaid video generator free?
Yes, you can try it for free. Every visitor can create 2 free 6-second videos per day at 480p, with no account or card needed. Paid plans add monthly credits, higher resolution and longer videos. There is no free trial that converts into a paid plan.
How long does it take to generate a video?
Most videos finish in 60 to 180 seconds. Busy periods can take a few minutes more. Keep the page open and the result appears automatically.
What photos work best?
Use a sharp, front-facing photo with good lighting and a single main subject. Avoid heavy filters, very small faces and group photos. Only upload photos of yourself, or of adults who have given you permission.
Can I use the videos on TikTok, Instagram or YouTube?
Yes. Under our Terms of Service you may use the videos you create. Free, Starter and credit pack videos are licensed for personal use; Pro and Studio plans include a commercial use license for ads, client work and monetized channels.
Do you create videos of famous characters like Ariel?
No. Monnvia only creates original mermaid characters. Prompts that reference copyrighted or trademarked characters, films or real celebrities are blocked to respect intellectual property and personal rights.
Is my photo private?
Uploaded photos are used only to generate your video. They are stored temporarily with our processing provider and deleted automatically within 72 hours. We never sell your data or use your photos to train models. See our Privacy Policy for details.
Is Monnvia family-friendly?
Yes. Adult, violent and hateful content is blocked, and every request passes a safety filter. Accounts and purchases are for users aged 18 and over, and photos of minors may not be uploaded.
Plans, billing and refunds
How do credits work?
Paid plans and credit packs use credits, charged per second of video: 2 credits per second at 480p, 4 at 720p and 7 at 1080p. A 6-second 480p video costs 12 credits. If a generation fails, the credits are returned.
Do subscriptions renew automatically?
Yes. Monthly plans renew every month and yearly plans renew every year at the price shown at checkout, until you cancel. Yearly plans receive their credit allowance every month, and we email you a reminder at least 7 days before each yearly renewal.
How do I cancel?
Cancel anytime using the "Manage subscription" link in your Stripe receipt email, or by emailing billing@monnvia.shop. Cancellation stops future renewals; you keep your plan and remaining credits until the end of the current billing period.
Can I get a refund?
Yes. First-time subscribers can request a full refund within 7 days if they used less than 20% of their first month's credits. Unused credit packs are refundable within 14 days. Failed generations are always refunded in credits. See the Refund Policy for the full terms.
Do unused credits roll over?
Subscription credits reset at each monthly allocation and do not roll over. Credits from one-time credit packs never expire.
Which payment methods do you accept?
We accept major credit and debit cards (Visa, Mastercard, American Express, Discover) and wallets such as Apple Pay and Google Pay, processed securely by Stripe. All prices are in US dollars and card charges appear as MONNVIA.SHOP on your statement.
