Terms of service
Last updated November 10, 2026
By using aivideoexpand.com ("the site", "we") you agree to these terms. If you don't agree, please don't use the site.
Who can use it
You must be at least 18 years old. You sign in with your Google account; keep access to its email address, because it is how you get back into your account.
What the service does
You upload a video clip (MP4 or MOV, up to 60 seconds) and choose the new shape and quality. We send the clip to an AI video model, LTX 2.3 from Lightricks, run by our API provider fal.ai, which keeps your whole original clip and generates the missing edges, and we deliver the result to your account. You can't enter your own prompt. The added edges are created by AI and may contain mistakes or artifacts.
Videos you may upload
- Your own videos, or videos you have the right to edit.
- No sexual content, nobody under 18 in a sexual or harmful way, and no clips made to deceive or harass.
- No nudity, violence or other content listed in our acceptable use policy. The first frame of every clip passes an automatic content-safety check, and the model applies its own safety filter; either can block a video.
You confirm you have the right to use and edit every clip you upload, and we record when you confirmed it.
Credits
Videos use credits: the generator shows how many before you start, based on the length, quality and options you pick. Credits are taken when a video starts and returned automatically if it fails. Credit packs: $12.99 for 60 credits, $24.99 for 140 credits, $59.99 for 400 credits. Credits never expire, have no cash value, can't be transferred except with a gift link, and are lost if you delete your account.
Buying just one video
When you don't have enough credits for a video you can pay for exactly that video. The payment adds the credits the video needs and starts it.
Subscriptions
Plans: 60 credits a month for $9.90 a month, or 720 credits a year for $69.90 a year; 140 credits a month for $19.90 a month, or 1680 credits a year for $139.90 a year. A subscription renews automatically at the end of each period and adds its credits each time it is paid. You can cancel any time from My videos; it then ends at the end of the period you paid for, and you keep your credits.
Gifts
You can turn at least 5 of your credits into a gift link, or buy a pack as a gift. Anyone signed in who opens the link first gets the credits. Until it is claimed you can take it back. Keep links private: we can't return credits claimed by someone you shared the link with.
Payment
Prices are in US dollars and are the final price; buyers in the euro area see and pay the same figures in euros; checkout may also offer your local currency at Stripe's exchange rate. Payments are processed by Stripe and appear on your statement under AIVIDEOEXPAND.COM; Stripe emails a receipt. Plans renew until you cancel them on My videos. Refunds are described in the refund policy.
Content rules
You may not use the service to create sexual or NSFW content, violent or gory content, hate speech, anything that sexualises or endangers children, deepfakes that impersonate or mislead, or content that infringes someone else's rights. The full list, how we check uploads and how to report a video is in our acceptable use policy, which is part of these terms.
AI-generated content
The edges added to your clip are generated by AI: they show what the model imagines beyond the original frame, not what was really there. When you share a video, label it as AI-edited where the platform asks for it.
Your videos
You may use your expanded videos however your rights in the original clip allow. The result contains your original clip and its sound with AI-generated edges; we claim no rights in it. You are responsible for having the right to use and edit the clip you uploaded.
No affiliation
The site is not affiliated with TikTok, Instagram, YouTube, Lightricks or fal.ai. Platform names are used only to describe the video shapes they use.
If you break these terms
We may block videos, delete the clips and videos concerned, and close the account. You are responsible for the clips you upload and for how you use and share the videos, and you agree to cover any claims, losses or costs that third parties bring against us because of that use.
Disclaimer and liability
The service is provided "as is" and "as available"; see the disclaimer. To the extent allowed by law, we are not liable for indirect or consequential losses, and our total liability for any claim is limited to what you paid us in the 12 months before it.
Changes
We may update these terms and prices. The date at the top shows the latest version; prices you already paid don't change, and a change to a subscription's price applies from its next renewal after we tell you.
