Image to video AI FAQ.
Free access, model choice, prompt length and render cost — the short answers.
What is image to video AI and how does it work?
It turns one still photo into a short clip. The model estimates depth and edges in your frame, then predicts how light, hair, fabric and background should move, so a single picture becomes a few seconds of camera movement. Nothing is filmed and nothing is imported from stock.
Is image to video AI free?
Yes. Upload a frame and render the daily free clip without signing up, and the allowance renews on its own. Longer clips, higher resolution and premium engines spend credits, charged once per render, and a failed render returns them.
Is image to video free and unlimited?
It means the free channel stays open: no login wall, no countdown, no card before your first clip, and a free render that comes back every day. It is not an endless supply of 1080p renders on every engine, since premium models still consume credits.
Can I make an image to video without signing up?
No. Open the page, upload a frame and render the daily free clip as a guest. An account is only there to keep your videos in history across devices and to hold any credits you buy.
Which image to video AI models can I choose?
Kling 3.0 and 2.6, Wan 3.0 and 2.6, Veo 3.1, Sora 2, Seedance, MiniMax H3, Vidu Q3, HappyHorse and Grok Video. Grok Video 1.5 at 480p / 6 seconds is the free engine; cheaper models are for finding the right prompt, and the premium ones are for the take you publish.
How do I write a good image to video AI prompt?
Name one camera move, one action and one light, for example "slow dolly forward, steam rising from the cup, warm window light". Stay under about 25 words and change a single detail per re-render. The start frame does the composition; the prompt only moves it.
How long can a clip be?
Duration depends on the model, usually 5, 10 or 15 seconds. Short clips read better in feeds, longer ones suit product walkthroughs, and the cost of each option is shown before you submit.
Can the video have sound?
Some models generate audio alongside the clip, typically ambience or short effects. Switch it on per render when the engine supports it; music and voice-over still come from your editor.
Which aspect ratios are supported?
16:9, 9:16, 1:1 and adaptive, which follows the shape of your start image. Choose the ratio before rendering, because reframing a finished clip means a second render.
Do renders have a watermark?
The studio does not add one. Clips download as MP4 files you can post, ship to a client or drop into an edit.
What happens if a render fails?
Credits are returned automatically and the job is marked failed, so a bad take costs time rather than credits. Adjust the prompt or settings and run it again.
Can I use the clips commercially?
You can use what you generate, subject to the Terms of Use and the terms of the model providers. Read the Intellectual Property Rights page before a paid campaign, since some engines restrict specific uses.
What kind of photo works best for photo to video?
A sharp frame with the subject fully inside the crop, even light and a visible background. Product shots on white work, but ones with a little depth behind the subject move better because the model has somewhere to send the camera.
Can I convert an image to video without editing skills?
Yes. There is no timeline and no keyframes: you upload, type one sentence and press render. The editor is where you cut the results together afterwards, and one clip does not need one.
How much does an image to video AI cost after the free clip?
The daily free render costs nothing, including on the entry model. Paid takes are priced per render before you submit, based on engine, duration and resolution, so a 5 second 480p test is the cheapest way to find a prompt that works.
Why does my render look soft or jittery?
Usually the start frame. A tight crop, motion blur, heavy filter or low resolution leaves the model inventing detail. A cleaner, larger frame with breathing room around the subject fixes most of it, and a simpler camera move fixes the rest.
Can I generate video from a phone photo on mobile?
Yes. Upload from the camera roll in the browser, and the render runs on the server, so the phone only has to hold the page. You can close the tab and come back to the result in your history.
Can I use Sora 2 for image to video?
Yes. Sora 2 is one of the engines in the model list, and it takes a start frame like the others. It is a premium model, so a take spends credits, which is why the usual advice holds: find the prompt on a cheap engine first, then run the version you keep on Sora.
Can I make a clip loop seamlessly?
A loop needs the last frame to arrive back where the first one started. Orbit moves and slow push-ins loop far better than a pan, which always lands somewhere new. Render the shortest duration the engine offers, then trim the tail in an editor until the two ends meet.
Can I upscale a finished clip?
Render at the highest resolution the engine offers rather than enlarging afterwards. Upscaling a compressed MP4 softens skin and fabric first, and the loss is obvious on a phone at full brightness. If the shot matters, spend the credits on a second higher-resolution render of the same prompt.
Which style works best for image to video?
Photoreal works best for products, interiors and portraits, because the start frame already carries the look. Illustration and line art survive motion well too, since flat color hides small errors. What fails is a heavily filtered photo: the model amplifies the filter along with the movement.
What happens to the images I upload?
Uploads are re-encoded, stripped of metadata and stored privately, then served only through routes tied to your own history. Nothing is published, and deleting a result removes the stored frame as well as the clip.
Can I add text or captions to the clip?
Add them in your editor after download. Text baked into the start frame gets animated by the model, which usually looks wrong, and a caption burned into the video cannot be edited for a second platform. Keep the render clean and overlay the words in post.
What format do the clips download in?
MP4, which is what every editor, ad platform and phone gallery accepts. The file lands in your history with the prompt and settings attached, so you can tell two similar takes apart a month later. Nothing is watermarked and nothing expires.
How do I improve a take I almost like?
Change one element and re-render: shorten the move, simplify the background, or drop an action the model struggles with. Two or three passes on a cheap engine usually beats one expensive guess, and the version you keep is worth the premium settings afterwards.
