AI text to video FAQ.
Free access, prompt length, model choice and cost — the short answers.
What is an AI text to video generator?
It renders a short clip from a written description. You name the subject, the action, the camera move and the light; the model predicts how that scene should look in motion and returns a few seconds of video, with no photo or footage as input.
Is text to video AI free?
Yes. You get one free clip per day on the entry model, no sign-up needed, and the allowance resets the next day. Longer clips, higher resolution and premium engines spend credits, charged once per render and refunded if the render fails.
Can I make a text to video without signing up?
No. Write a prompt and render the daily free clip as a guest. An account keeps your videos in history across devices and holds any credits you buy, and nothing about the first clip depends on it.
Which AI text to video 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 prompt, and the premium ones are for the take you publish.
How long should an AI text to video prompt be?
One or two sentences, under about 25 words. Subject, action, camera move, light, in that order. Anything past that adds adjectives the renderer cannot use and starts competing with itself. Write it as a description of a frame, not as marketing copy.
Text to video vs image to video: which one?
Text to video starts from nothing, so the model designs the look. Image to video starts from your photo and keeps it. Use text when the scene does not exist yet; use image when a product, face or room has to stay exact.
How long can a clip be?
Usually 5, 10 or 15 seconds, depending on the model. Short clips read better in feeds, longer ones suit explainers, and the cost of each option is shown before you submit.
Can a generated clip have sound?
Some models generate ambience or short effects alongside the clip. Switch it on per render where 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. Choose the ratio before rendering, because reframing a finished clip means a second render.
Do renders have a watermark?
No. 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 money. 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.
How much does an AI text to video clip cost?
The daily free clip costs nothing on the entry model. Paid takes are priced per render before you submit, by engine, duration and resolution, so a five second test stays cheap and only the published version gets the expensive settings.
Can I turn a script into video?
Yes, one shot at a time. Split the script into single actions, write one prompt per line, render each, then cut them together. A full scene in one prompt comes back with a camera that tries to do three things at once, which is where most attempts fail.
What are the best text to video prompts?
Short, concrete and camera-aware: "wide shot, cyclist turns a corner, handheld follow, overcast morning". Name a shot size, one action, one move and one light. Prompts that work read like a line from a shot list rather than a paragraph of atmosphere.
Can I storyboard with text to video?
That is one of the better uses. Render each planned shot at low resolution, drop them into the timeline in order, and check whether the sequence reads before anyone books a set. Clients react to a rough cut faster than to a board of frames.
Does the prompt have to be in English?
English gives the most predictable results, because the training data behind most video models is weighted that way. Other languages work and often translate the intent correctly, but if a render keeps missing the point, try rewriting the same sentence in English first.
Can I keep one character consistent across clips?
Describe the same person with the same words in every prompt: age range, hair, clothing, build. Repeat the description word for word instead of paraphrasing, and keep the shot size similar. It is not a locked face, so a clip that has to match a real person belongs on the image to video page instead.
Can I render text to video on Sora 2?
Yes. Sora 2 sits in the model list and takes a written prompt like the rest. It is a premium engine, so a take spends credits, which is why the sensible order is: test the sentence on a cheap model, then run the version that works on Sora for the shot you publish.
Can I write a prompt that loops?
Ask for a move that ends where it began, such as an orbit or a slow push that settles back. Keep the duration short, because a long loop drifts. Then trim the last half second in an editor so the join is invisible and the clip can repeat in a feed.
Can I upscale a text to video clip?
Render at the highest resolution the engine offers instead of enlarging afterwards. Upscaling works from a compressed MP4, so texture and skin soften first. If a shot is going into a paid campaign, re-render the same prompt at a higher setting rather than stretching the file.
Do I have to upload anything?
No. A text to video clip needs a prompt and nothing else, so there is no photo in the workflow at all. Your prompts and results stay in your own history, and deleting a result removes it from there.
Can I add captions or a logo to the clip?
Add them in your editor after download. A logo described in a prompt comes back redrawn and slightly wrong, and text baked into the render cannot be changed for a second platform. Keep the clip clean and overlay words where you can still edit them.
What format does a text to video clip download in?
MP4, ready for any editor, ad platform or phone gallery. The prompt and settings travel with the file in your history, so a take from three weeks ago can be rebuilt instead of guessed at.
Can I reuse a prompt that worked?
Yes, and that is the fastest way to build a series. Keep the description of the subject and the light, then change only the action or the camera move. A saved prompt is worth more than a saved clip, because it works on the next shot too.
