How Does AI Video Generation Work? A Plain-English Explainer
By the Maybe Labs teamAI video generation turns a text prompt into moving images using a model trained on huge amounts of video. In plain terms: you describe what you want, the model predicts what each frame should look like so the sequence stays coherent over time, and it renders a clip. Most modern tools use diffusion models — they start from visual noise and denoise it, step by step, into frames that match your prompt. That's the core of generative tools like Veo, Runway, and Kling. Motion-graphics tools like Maybe Labs work differently: instead of predicting photoreal frames, they generate a designed, editable video from your brief.
The short answer
- You give a text (or image) prompt describing the video.
- A model trained on video predicts coherent frames over time.
- Diffusion models denoise random visual noise into matching frames.
- Output is a clip — which you may still edit, brand, and assemble.
Step by step
First, your prompt is encoded into a representation the model understands. The model then generates frames while maintaining temporal consistency — the hard part, because objects, lighting, and motion must stay believable from frame to frame, not just look good in a single still. Diffusion-based systems do this by repeatedly refining noise toward the target; some newer models generate synchronized audio in the same pass. Finally the clip is decoded to standard video (MP4). For the input side of this, see text-to-video AI, image-to-video AI, and prompt-to-video.
The main types of AI video tools
| Type | How it works | Examples |
|---|---|---|
| Generative (text-to-video) | Predicts photoreal frames from a prompt | Veo, Runway, Kling |
| Avatar | Drives a synthetic presenter from a script | HeyGen, Synthesia |
| Template + stock | Matches a script to stock clips and templates | InVideo, Pictory |
| Motion graphics | Generates designed, editable, on-brand video | Maybe Labs |
What AI video generation can't do well (yet)
Generative models still struggle with reliable on-screen text, exact product accuracy, longer coherent stories, and keeping a specific brand look. That's why raw generative clips make great b-roll but poor launch videos — you'd add structure, editable copy, and a CTA yourself. Understanding this distinction is the whole point of AI video editor vs generator.
How motion-graphics generation is different
Instead of predicting photoreal pixels, a motion-graphics tool like Maybe Labs interprets your brief and composes a designed video from editable elements — animated UI, kinetic type, layouts in your brand colors and fonts. The result is on-message and on-brand by construction, not by luck, and it exports in 16:9, 9:16, and 1:1. That's why it fits product and launch videos where a generative clip doesn't.

How AI video works FAQ
What model do AI video generators use?
Most modern generative video tools use diffusion models (often diffusion transformers), which turn random visual noise into coherent frames that match your prompt. Some also generate synchronized audio in the same pass.
Is AI video generation the same as deepfakes?
No. Deepfakes specifically swap or synthesize a real person's face or voice. General AI video generation creates new scenes or designed graphics from a prompt and isn't tied to impersonating a specific person.
Why do AI videos get text and hands wrong?
Because the model predicts pixels frame by frame rather than rendering defined objects. Fine, structured details like legible text and hands are hard to keep consistent. Motion-graphics tools avoid this by using real, editable text layers.
Can AI generate a full marketing video automatically?
Generative clip tools can't — you assemble and brand the output. A motion-graphics generator like Maybe Labs can produce a finished, on-brand product video from a single prompt.
Now that you know how it works, pick the right type for the job. For an on-brand product video from a prompt, describe it to Maybe Labs.
