AI Video Generator
The most powerful AI video generator online. Turn text prompts and images into cinematic videos in seconds with Veo 3.1 and more. Free to try — no editing skills required.
What Is an AI Video Generator?
An AI video generator uses deep learning models trained on massive video datasets to turn natural-language prompts and images into original moving footage. Describe a scene — a product demo, a cinematic landscape, a talking character, or an animated concept — and the AI video generator renders it in seconds. Modern systems like Veo 3.1 have pushed AI video generation to cinematic quality with synchronized motion, lighting, and sound, making professional video accessible to anyone.
How AI Video Generation Works
Diffusion and transformer models synthesize each frame and interpolate smooth motion guided by your prompt. Every pass refines detail, camera movement, and temporal consistency until the clip matches your description.
Text-to-Video Prompting
Describe your scene in plain language. The AI video generator interprets subject, action, camera angle, lighting, and mood — even multi-shot sequences — from a single sentence or paragraph.
Image-to-Video Animation
Upload a still image and let the AI video generator bring it to life. Add camera pans, natural motion, and cinematic effects to transform a single photo into a dynamic clip.

AI Video Generator — Frequently Asked Questions
Everything you need to know about creating videos with AI on Nana Banana Pro.
What is an AI video generator?
An AI video generator is a machine learning system that creates original videos from text prompts or images. It uses diffusion and transformer models trained on large video datasets to synthesize moving footage that matches your description — no camera, editing, or animation skills needed.
Is the AI video generator free to use?
New accounts receive free credits on signup and can earn more through daily check-ins. These credits let you try the AI video generator at no cost. Paid plans unlock longer videos, higher resolution, and priority queue access.
What is the difference between text-to-video and image-to-video?
Text-to-video generates an entirely new clip from a written prompt. Image-to-video takes a still image you upload and animates it — adding motion, camera movement, and cinematic effects — guided by your text direction.
Which AI video models are available?
Nana Banana Pro gives you access to Veo 3.1 and Veo 3.1 Fast — Google's advanced video models with realistic motion and synchronized audio. Choose Veo 3.1 for maximum quality or Veo 3.1 Fast for quicker turnaround.
How long does AI video generation take?
Most AI video generator requests complete in one to three minutes depending on the model, duration, and resolution. Veo 3.1 Fast returns results quicker, while full-quality generations take slightly longer.
What aspect ratios and resolutions does the AI video generator support?
You can generate videos in landscape 16:9, portrait 9:16, and square formats in HD. Portrait output is ideal for TikTok, Reels, and Shorts, while landscape suits YouTube and product pages.
Can I use AI-generated videos commercially?
Videos created on Nana Banana Pro can be used for personal and commercial projects. Review the specific model's usage policy for details — Veo 3.1 outputs follow Google's usage terms.
How do I write a good AI video generator prompt?
Be specific about subject, action, camera movement, lighting, and mood. For example: 'A slow cinematic dolly shot of a red sports car driving along a coastal road at golden hour, dramatic lighting.' More detail produces more accurate AI-generated videos.
Can ChatGPT or Gemini generate videos?
ChatGPT and Gemini are primarily text and image assistants and do not directly generate finished videos. To create AI video you need a dedicated AI video generator like Nana Banana Pro, which runs purpose-built video models such as Veo 3.1.
What is the best AI video generator in 2026?
The best AI video generator depends on your needs, but models like Veo 3.1 lead on realism, motion quality, and synchronized audio. Nana Banana Pro gives you access to these top models in one online AI video generator with free credits to start.
