AI Video Generator: Describe the Video, Get It Finished

What is an AI video generator?

An AI video generator is software that creates video from text, pictures or a link, using AI models instead of filming. There are two levels. A clip model turns one prompt into a shot a few seconds long, which you still have to write around, voice, edit and caption. A full AI video generator turns an idea into a finished video: script, voice, a chain of scenes, captions and the edit, in one file you can post.

Most people who search for an AI video maker want the second: a video, not a shot. FacelessCast is that kind. You never touch a timeline; you say what the video should be, check the plan, and get the finished file, with the option to change one scene afterwards.

What can you make with an AI video generator?

Anything you can describe in a few sentences and nobody needs to film. These are the kinds of video FacelessCast makes:

• Shorts, TikToks and Reels: a vertical explainer, a fact, a story beat or a joke, 15 seconds to 3 minutes, with a hook in the first second.
• Story videos and kids episodes: recurring characters who keep one face and speak their own lines, episode after episode.
• Films with no narrator: when you ask for a scene rather than an explainer, characters act and speak their own lines, and nobody reads over them.
• Long-form YouTube videos: up to 20 minutes with chapters, usually on real stock footage, which costs no credits.
• Product promos: a presenter pitches your product while every step shows your real screens, from a pasted link.
• UGC-style ads: a creator holds, shows and uses your real product, the way people post on social media.
• Versions: the finished video in English, Turkish, German, Spanish or French, or with other opening hooks to test.

How does an AI video generator make one video?

In FacelessCast one message runs through eight steps, and you only take part in the first two:

• 1. The brief: you describe the video in the studio chat. It asks only what is truly missing, such as the length when nothing hints at it, and decides the rest with defaults you can see.
• 2. The plan and the price: a plan card shows the format, length, frame, voice and the price in credits. Nothing starts until you accept, and you can see every scene first in a free storyboard.
• 3. The script: written hook-first at the length you asked, or your own script, read word for word.
• 4. The voice: a natural AI voice in any of 37 languages, at a pace measured for each language.
• 5. The scenes: every scene becomes a generated AI video clip of about six seconds, or a licensed stock clip under every sentence. Characters are drawn from saved portraits, so the same person appears in every scene.
• 6. Talking scenes: the line is voiced first and the character's mouth follows its syllables.
• 7. The finish: word-synced captions in the style you pick, music when you ask for it, a cover and a publish kit with titles, description, tags, hashtags, chapters and .srt and .vtt caption files.
• 8. The render: an MP4 in 16:9, 9:16 or 1:1, up to 1080p on Starter, 1440p on Creator and 4K on Pro and Studio, with no watermark on any plan.

AI video or real stock footage: which should you use?

Use AI video for what nobody can film, and real footage for what is real. AI video, where every scene is a generated clip that moves, suits stories, fiction, characters, the distant past and ideas. Real stock footage suits real places, animals, products and facts, because a generated clip of a real place is an imagination of it.

The two also cost differently. Stock-footage videos use no credits and are unlimited on every plan, so they carry long-form and daily uploads. AI video is paid per clip in credits, so it fits Shorts, story episodes and the videos where moving scenes make the difference. You choose per video, and the studio tells you which it will use before anything starts.

Can AI characters talk and keep the same face?

Yes, when every scene starts from the same saved reference. In FacelessCast a character is saved once with a portrait, in the character library or a series bible, and every scene of every episode is drawn from it, so face, hair and clothes stay the same. Photographic characters are made to look like real, candid photos rather than glossy renders.

A talking scene costs 40 credits at standard quality. Each character gets its own voice and speaks its own lines, and the lip-sync follows the voiced line, not a generic loop. It needs a clear, front-facing character; a scene that cannot be made to talk stays a regular AI clip and the difference is refunded. Presenters are generated people, and FacelessCast does not clone real voices.

How long does it take to make an AI video?

A short stock-footage video is usually ready in one to three minutes. An AI video, where every scene is generated, takes about ten minutes per minute of video, because each six-second clip is made from scratch and talking scenes need a second pass for the lips.

Videos render in the background: you can plan the next one while the first is made, and on Pro and Studio two or four videos render at once. The finished video appears in your library with its publish kit.

How much does an AI video generator cost?

An AI video generator costs whatever one finished minute costs at the quality you publish, so compare that number, retries included, not the plan price. On FacelessCast, stock-footage videos cost nothing beyond the plan, and AI video is paid in credits worth about 5 cents each:

Plans include monthly credits: 400 on Starter at $10, 800 on Creator at $19, 2,000 on Pro at $49 and 4,000 on Studio at $99, or 20% less paid yearly. Credit packs start at $5 for 100 credits, can be bought with or without a plan and never expire. A clip that cannot be generated is refunded, and if an AI video cannot be finished the render stops and every credit comes back, rather than a still picture being slipped in.

Can you make AI videos for free?

Partly, and it is worth knowing which part. On FacelessCast the chat, the plan, the price and a storyboard of every scene are free, and every account's first video is free: one video cut from real stock footage, up to 2 minutes at 1080p, with a small watermark and no card needed.

AI video itself is never free here, because every generated clip takes real computing time. The smallest way in is a $5 pack of 100 credits, enough for a 12-second AI video twice. Wherever you try a free AI video maker, check before you publish whether its free tier adds a watermark, caps the resolution or length, or forbids commercial use.

What does YouTube ask of AI-generated videos?

YouTube allows AI-generated videos and asks for two things: a disclosure when the content looks real, and originality if you want to earn. Answer Yes to the AI use setting in YouTube Studio when a video contains realistic AI-generated or altered content, such as realistic footage of a real place; clearly unrealistic content, animation and help with the script or captions do not need it. Since May 2026, YouTube labels a video itself when its systems detect significant photorealistic AI use that was not disclosed, and it says a label alone does not change how a video is recommended or whether it can earn.

Earning is judged on the channel. YouTube's monetization policies exclude inauthentic content, which is mass-produced, generic or repetitive, including AI-generated content made with generic templates that gives the impression of mass production, and AI clips stitched together to surprise or shock with no clear narrative. A video with its own idea, script and story, made one at a time, is on the right side of that line.

What FacelessCast's AI video generator does not do

It has no free plan or trial: plans start at $10 a month, and only the first stock-footage video is free. It does not edit or clip your existing footage, clone your voice or upload videos to YouTube for you. Generated clips last about six seconds each, so action is told in shots, and lettering inside a generated picture, such as a sign or a screen, can come out wrong. AI video is at its best in Shorts and story episodes; long videos usually run on stock footage, which costs no credits.
