AI Video Generator
100% Free No sign-up No login No paywall
AI Video Generator builds a complete video direction prompt from your idea: subject and action, style, duration, aspect ratio and audio or dialogue. That prompt is what real video AI tools need, and it works free on this page. This site is honest about one thing: no website can render a real video in your browser for free — video rendering needs a video-generation provider. So instead of faking a video, we give you a production-ready direction you can paste into your video tool, plus a scene plan. The Video Clipper tool on this site handles real video files you already have. And if you want a LONG video — up to 30 minutes — use the Long Video Maker: it builds a real video from your own images, short clips and script, with voiceover and music, right in your browser.
How to use AI Video Generator
- Describe your video idea — what happens, where, and who is in it.
- Pick a style, duration and aspect ratio (16:9 for YouTube, 9:16 for Shorts).
- Add audio or dialogue notes, like “natural ambience, one line of dialogue”.
- Press “Build Direction” and copy the full prompt into your video AI tool.
Worked example
Example: idea “a cinematic night market in Lahore, rain on the street, a vendor serving tea”, style Cinematic, duration 10 seconds, ratio 9:16. The builder returns a full direction — shot list, camera movement, lighting, motion notes and audio — ready to paste into a video generator, plus a note that rendering happens in that provider.
Tips for better results
- One clear action per clip works best — video models handle short, simple scenes well.
- Add camera language: “slow dolly in”, “aerial view”, “close-up” changes the result a lot.
- For Shorts and Reels use 9:16 and keep the idea to one strong moment.
- Write the dialogue separately so the tool does not garble it into the visuals.
Frequently asked questions about AI Video Generator
Does this tool render a real video?
No — and no free browser tool honestly can. It builds a professional video direction prompt you paste into a video-generation provider. Anything that claims to render video for free in the browser is faking it.
Is the prompt builder free?
Yes, completely free, no API key and no sign-up.
Which video tools can I paste the prompt into?
Any text-to-video tool that accepts a prompt — for example Runway, Pika, Kling, Luma or Sora, depending on your access.
Can I plan a full video here?
Yes — the direction includes scene, camera, lighting and audio notes. For a full script use the AI Script Writer on this site.
What ratio should I choose?
16:9 for YouTube long videos, 9:16 for Shorts, Reels and TikTok, 1:1 for social feeds.
How long can AI video be?
True AI-generated footage (text-to-video tools like Sora, Runway, Kling or Veo) only makes SHORT clips — typically 5–10 seconds per clip, sometimes up to about 30 seconds to 1 minute with paid tools — and it needs a paid API key. No tool anywhere generates a full 15-minute AI video in one go, free or paid, and this site will never claim otherwise. BUT you can still make a 15-minute (or up to 30-minute) video here: the Long Video Maker on this site builds a real video from your own images, short clips and script, with AI voiceover and music, and exports it as a WebM file. That is how long videos are honestly made in a browser.
Can I edit a video I already have?
Yes — use the Video Clipper tool: preview your video, define clips and download a clip plan.
