How does the preview-generation AI work on Moleculai?

You describe the scene, style and length - the AI creates a video based on a text prompt or an uploaded image. Generation takes anywhere from 30 seconds to a few minutes depending on complexity. The platform lets you create short clips, animations and content videos with no video editing skills required.

What formats does the AI preview tool support?

The platform lets you create short videos (5-15 seconds), animated clips, and videos from still images or text descriptions. It works for Reels, Stories, ad previews and educational content. You can download the finished file and use it anywhere. Format and aspect ratio adjust to the target platform - vertical for mobile, horizontal for YouTube.

How much does the AI preview generator cost?

Video generation is available on Moleculai's paid plans. The Pro plan (≈$21/month) includes a basic generation limit. Expert (≈$98/month) gives you higher limits. Free generations after signup are enough to try it out. It's significantly cheaper than professional AI-powered video editors.

Can I create a preview from images with AI?

Yes, Moleculai has a tool for creating video from a still image. Upload a photo and describe the motion you want - the AI brings the picture to life with smooth animation. It works for turning portraits into animated avatars, bringing landscapes to life, and creating dynamic content from your photo archive. The result comes out smooth and realistic.

How good is the quality of AI-generated previews?

Quality depends on how detailed the prompt is and which settings you choose. With a detailed scene description - subjects, movement, lighting, style - the AI produces well-detailed clips. That's more than enough for social media and short formats. For professional production, you can use the generation as a draft or reference. Every new generation is unique, even with the same prompt.
