What an AI video generator like Vaideo actually does
"AI video" tools come in two broad families. Some generate synthetic clips shot by shot from a prompt; others, like Vaideo, assemble a complete narrated video: they write a script, turn it into a voiceover, match an image to each line and animate it with zoom and pan (the Ken Burns effect) plus burned-in captions. The result looks more like an explainer or a short documentary than a cinematic clip.
That distinction matters when you choose a tool. If you need to tell something—a list of tips, an article summary, a story, a fun fact—the narrated format works best and breaks least often. If you want characters moving on screen or a talking avatar, Vaideo is not the right fit: it does not generate avatars or moving characters (though you can add your own footage afterwards in Vaideo Editor (free)).
Images come from free libraries (Unsplash and Wikimedia Commons) or, if you switch it on, are generated by AI. You can apply one of 10 visual styles (Real photo, Cinematic, Documentary, Anime/Illustration and more), add a style hint that applies to every scene, and swap the image of any scene you don't like.
What the free plan includes and when a paid plan is worth it
The Free plan costs €0 and includes 1 free video a day up to 30 seconds, exported in 720p with a watermark; it's generated in turn, in a queue. That's enough to try the whole workflow, test a format or post a short every day. If you want videos without the watermark, you need a pack (from €5). If a generation fails, it doesn't count against your quota.
Packs are a one-off payment and never expire: 5 videos for €5, 15 for €12 or 40 for €25. Each video runs up to 5 minutes, exports in 1080p without a watermark and is generated ahead of free ones. Unlimited costs €39 a month and gives you unlimited videos (fair use) up to 10 minutes, no queue, direct upload to YouTube by connecting your account and AutoPilot (creates and publishes videos automatically on a connected channel). You can cancel it any time.
Rule of thumb: if you need anything longer than 30 seconds, 1080p, or a watermark-free finish for a channel or a client, a pack pays for itself (5 videos for €5). If you'll publish several videos a day, need videos longer than 5 minutes, want to skip the queue or want direct YouTube upload, go for Unlimited. If you just want to experiment, the free plan is enough.
How to write a prompt that produces a good video
AI fills in the gaps, so the more specific your prompt, the less generic the script. State the topic, the angle and, ideally, the structure: "5 mistakes when…", "the story of…", "why … happens". Naming the audience ("for beginners", "for parents") shifts tone and vocabulary.
Think about the visuals too. Concrete, visual topics (places, objects, animals, historical periods) find better photos in free libraries than very abstract ideas. If your topic is abstract—productivity, anxiety, money—pick a style such as Minimal/Abstract or turn on AI-generated images to avoid repetitive stock shots.
If the content already exists in writing, paste the article URL: Vaideo condenses it into a narrated script. It's the quickest way to repurpose a blog post or newsletter as video.

Tips that make the difference
- ★Use your daily free video to test different formats (list, question, article summary) before deciding whether you need a pack.
- ★Keep Free-plan videos to 30 seconds or less: ask for "in 25 seconds" explicitly in the prompt.
- ★Always review the script: AI can get specific facts, dates or figures wrong.
- ★If an image doesn't match its line, replace it instead of regenerating the whole video.
- ★Add a shared style hint (e.g. "warm tones, natural light") so every scene looks consistent.

Frequently asked questions
Can you really create AI videos completely free?+
Yes, within limits. Vaideo's Free plan allows 1 free video a day up to 30 seconds, in 720p with a watermark. To remove the watermark, get 1080p or make longer videos you need to pay: a pack from €5 (up to 5 min, one-off) or Unlimited at €39/month (up to 10 min).
How long does it take to generate a video?+
Usually between 2 and 6 minutes, depending on length and the number of scenes. It's worth spending a few extra minutes reviewing the script and images afterwards.
Can I use the videos commercially?+
The videos you generate are yours. Unsplash images carry a free licence that allows commercial use; some Wikimedia Commons images may require crediting the author, so check each licence if you plan to monetise.
Which languages can the AI narrate in?+
English and Spanish, with one natural AI voice per language. You can't pick specific accents or clone your own voice.
Can I add background music or my own clips?+
Yes, afterwards: the AI produces the video with narration, animated images and captions, without music. Then you can open it in Vaideo Editor (free) and add your own clips and royalty-free music, or add music in the platform where you publish.
Which video formats can I create?+
Horizontal 16:9 for YouTube and vertical 9:16 for Shorts, Reels and TikTok. There's no square 1:1 option.
What happens if a generation fails?+
Failed videos don't use up your quota, so you can try again without losing your free video for the day.
