Why Choose This?

Prompt-based video generation Turn natural-language scene descriptions into short video clips with controllable duration and format.
Two generation modes Choose std for higher-quality output or fast for quicker, lower-cost generation.
Multiple resolutions Supports 480p, 720p, and 1080p to balance quality and budget.
Flexible aspect ratios Choose 16:9, 9:16, or 1:1 for widescreen, vertical, or square delivery.
Optional sound effects Enable sound when you want the video generated with audio effects.
Production-ready API Suitable for short-form content, ad concepts, storytelling, social media clips, and rapid prototyping.
