Type a prompt → AI generates a video clip (8 seconds or concat). Uses Google's Veo model.

Upload an image + type a motion prompt → AI animates it into a video.

Enter multiple prompts separated by blank lines:

A cute cartoon boy reading under a tree

A girl walking through a neon city at night

A dragon sleeping on a mountain of gold

Each prompt is processed one by one. The queue shows progress.

Process 1-6 prompts at the same time. Higher = faster but uses more credits.

Wait time between prompts (default: 20-30 seconds). Prevents rate limiting.

Generate 1-4 images per prompt. More outputs = more variations to choose from.

Automatically adds quality descriptors to your prompts. Choose from 5 styles: Detailed & Sharp, Cinematic, Photorealistic, Artistic, Minimal Touch.

Select from: 🍌 Nano Banana 2 (default), 🍌 Nano Banana Pro, Imagen 4, ImageFX Default.

Automatically renames downloaded files with the prompt text + timestamp. Organized in subfolders.
