AI Video Generation Technology Explained
A creator-friendly explanation of how modern video models interpret text, image references, timing, and motion.
From prompt to moving scene
Video models translate text into a sequence of visual states. They infer people, camera movement, background, and action from the prompt.
Shorter, clearer prompts often produce more consistent motion than long prompts full of competing details.
Why image-to-video helps
An image reference anchors composition and subject placement. The prompt can then focus on motion, expression, and dialogue.
Why costs vary
Resolution, duration, and model class all affect compute cost. That is why credit systems usually charge by seconds and quality tier.
